“We have a hunger of the mind which asks for knowledge of all around us, and the more we gain, the more is our desire; the more we see, the more we are capable of seeing.” -Maria Mitchell, Astronomer (1818-1889) “But science and everyday life cannot and should not be separated. Science, for me, gives a partial explanation for life. In so far as it goes, it is based on fact, experience and experiment.” -Rosalind Franklin, Biophysicist and Physical Chemist (1920-1958)

The Douglass Project for Rutgers Women in Math, Science, and ! Engineering Encouraging women in the STEM fields Established in 1986, the Douglass Project for Rutgers Women in Math, Science & Engineering is an award-winning program that provides support and encouragement for undergraduate women pursuing degrees and careers in, science, technology, engineering, and mathematics. The original goals of the program included developing a network of support for undergraduate women students who were interested in math and science at Rutgers-New Brunswick and developing co-curricular programs to increase confidence of these students. Specific programs were organized where students could meet other young women interested in math and science majors and see that they were not alone in their endeavors. Over 25 years later, the Douglass Project continues to offer signature programs of support for women in science throughout Rutgers University. Each year the Douglass Project holds over 30 events and workshops that assist participants in enhancing their academic, career/professional and personal development. We also provide individualized advising with both graduate students and full-time staff specific to the needs of undergraduate women in STEM. A Network of Support Programs: Bunting-Cobb Residence Hall for Women in Science (the first of its kind in the nation) Project SUPER (Science for Undergraduates a Program for Excellence in Research) Douglass Engineering Living-Learning Community for first year women The STEM Ambassadors leadership program An industry mentoring program for woman in science in collaboration Outreach program with Rutgers DIMACS for women in computing Health Sciences Research Symposium planning committee We invite you to connect with us on Facebook (/DouglassProject) and Twitter (@DouglassProject).

STEM Summer Stipend

The STEM Summer Stipend provides Douglass students conducting scientific research with the opportunity to receive funding for their work during the summer as well as professional development workshops. Students work over 300 hours with a faculty advisor on a scientific topic of interest to them. In addition to presenting at this poster session, they also write a paper on their findings. We would like to thank the faculty, post-docs, and graduate students who hosted and mentored our students during the 2014 summer. All Douglass students interested in participating in the STEM Summer Stipend should apply during the spring semester prior to their summer of work. The Douglass Project expresses great gratitude to the generous contributors who support our mission. We extend great gratitude to Regina Best Heldrich '42, in memoriam, for generously creating the Regina Best Heldrich Science Endowment for Douglass students, which assists Project SUPER students in their research endeavors. We would also like to thank Wendy Cai-Lee, Carol Gershaw Myers, Barbara Rodkin and the Rodkin Family Foundation, and the Colgate-Palmolive Corporation for their continued financial support of our students.

Cilgy Abraham | Advisor: Dr. Pamela de Cordova Californiaâ&#x20AC;&#x2122;s Mandated Nurse-to-Patient Legislation and Patient Outcomes: A Systematic Review of the Literature

Inadequate staffing of nurses in healthcare facilities in the United States and abroad is a significant problem. The growing body of evidence suggests that high nurse-to-patient ratios may worsen selected patient outcomes and quality of care while contributing to the epidemic nurse shortage. In an effort to improve patient outcomes, California became the first state, in 1999, to pass Assembly Bill 394 which mandated minimum ratios in several units such as medical/surgical, step-down, specialty, and telemetry units at all times. This current systematic review examined the evidence revealing any changes in specific patient outcomes in California healthcare facilities after the implementation of the mandated ratios. Furthermore, the researchers evaluated the entire sample of selected articles for study quality. Ten out of the twelve articles had strong methodological rigor. A crucial finding from this systematic review is that the mandated ratios increased the number of nurse hours per patient day. Another finding is a decrease in the use of restraints and a drastic decrease in the time, from 103 to 62 minutes, from the written order to the administration of antibiotics for patients with pneumonia. While some patient and quality outcomes have improved post-regulation, others have not, making the findings from a majority of these studies mixed and inconclusive.

Cilgy Abraham is a junior of the Rutgers, School of Nursing Honors Program. Cilgy is interested in global health, quality of healthcare services and patient outcomes, nurse staffing, and access to healthcare in underprivileged communities. In addition to researching this summer, Cilgy worked with and monitored individuals with mental health issues and from that experience she has learned the importance of advocating with local, state, and federal authorities to improve the access to healthcare services for those living in underserved communities. Cilgy is also highly passionate about changing societal stereotypes concerning the nursing profession and hopes that her involvement in summer research will help others realize that nursing is a respectable profession that uses science, evidence-based practices, theory-guided practices, and of course research to improve the quality of patient care. Working with and being mentored by Dr. Pamela de Cordova has inspired Cilgy to someday pursue a doctorate in nursing.

Nimah Ahmed | Advisor: Dr. Nicole Fahrenfeld Reactive Transport Modeling of the Explosive TNT

Transport simulation has become an increasingly important tool for environmental scientists and engineers due to growing interest in groundwater quality as well as the rapid development of computer technology. However, few solute transport models account for complicated branched degradation pathways associated with many organic pollutants. The objective of this work was to develop a 1D reactive transport model to accurately simulate TNT transport and biodegradation. A finite difference approximation approach was used along with the assumption of a linear isotherm. The model was also applied to TNTâ&#x20AC;&#x2122;s daughter products ADNT and DANT as well the intermediate products HADNTs. The model was validated using previously published data from a column biodegradation study. Accuracy was evaluated using R2 values to approximate fit. Good results were achieved for TNT and the two ADNT products, with moderate results for the DANTs. Nimah Ahmed is a senior in the Rutgers School of Engineering. She is majoring in civil engineering with a focus in environmental and is involved with Engineers Without Borders. Her future career goal is to work in environmental consultation.

Suwaiba Asghar | Advisor: Dr. Huaye Zhang The Screening of Putative Proteins that affect APP Trafficking and Processing

Alzheimer’s Disease (AD) is a progressive neurodegenerative disease characterized by deposits of amyloid beta (Aβ) in senile and neuritic plaques and neurofibrillary tangles of paired helical filaments of hyperphosphorylated tau. Various studies indicate that overproduction and aggregation of Aβ in the brain is the primary cause of AD and inhibition of Aβ generation has become a popular topic in AD research. Aβ is generated through β- and γ-secretase cleavage of amyloid precursor protein (APP). Alternatively, APP can be cleaved by α-secretase within the Aβ domain to release soluble APPα and preclude Aβ generation. Hence, understanding the processing of APP is crucial for AD therapeutics. In Dr. Zhang’s lab, we previously screened for putative proteins that may play important roles in APP trafficking and processing and identified RhoA as a very likely candidate for the CTFα fragment that follows the non-amyloidogenic pathway. Now we used confocal microscopy to examine the effects of RhoA on APP trafficking. Results suggest that RhoA might influence APP through its cytoskeletal interaction, shifting the APP distribution from the Transgolgi-network to the recycling endosomes. Understanding the role of RhoA in APP trafficking and processing can elucidate the molecular mechanisms of the disease, which serves as great potential towards therapeutic advancement of AD.

Suwaiba Asghar is double majoring in Neuroscience and Cell Biology and Psychology at Rutgers University. She has taken her interest of neuroscience to a higher level by working in Dr. Huaye Zhang’s laboratory over at the Robert Wood Johnson Medical School. After working in Dr. Zhang’s lab for about three years, she has been working on her own project on Alzheimer’s Disease (AD) and is currently a research mentor for other students in the lab. Suwaiba also enjoys tutoring Organic Chemistry at the Rutgers University Learning Center and also is a TA for Molecular Biology and Biochemistry. Suwaiba is a Fellow for RUWINS, Rutgers University Women in Neuroscience, and enjoys inviting prominent women neuroscientists from around the world and helping other students connect with them. She is also treasurer of CBN Society of Rutgers University. Suwaiba also enjoys her non-science hobbies of doing henna and hanging out with her four younger siblings. Suwaiba plans to apply to dual MD-PhD programs so she can continue to do research and also treat patients, hopefully here at RWJUH.

Muzdalifa Ayub | Advisors: Dr. Wise Young and Dr. Patricia Morton Lumbosacral Spinal Cord Injury Project

Lumbosacral Spinal Cord Injury (LSCI) makes up about 1/3 of all spinal cord injuries in the world and results in damage to the spinal roots at the T11-L1 junction. Damage at this region affects the movement and control of all bodily muscles and functions from the waist down. Even with its paralyzing effects and its rate of occurrence around the world, a treatment for lumbosacral spinal cord injury is barely being researched around the world. At the W.M. Keck Center for Collaborative Neuroscience, one of the only labs actively researching to find a treatment for LSCI, the project has been divided into two objectives. The first objective is regenerating motor neurons at the site of injury and the second objective is to promote the growth of new nerve connections from those neurons to the atrophied muscles. This past summer, we have worked on the first objective of the project using female GFP rats as our animal model to observe the effects of introducing neurospheres at the site of injury. The project is still ongoing so no conclusive results have yet been found. Muzdalifa Ayub is a sophomore in the School of Arts and Sciences Honors Program, majoring in Cell Biology & Neuroscience. She began her research at the W.M. Keck Center for Collaborative Neuroscience under Dr. Wise Young's guidance in January of 2014 with the help of Project SUPER. She continued her research this past summer as a Rodkins Scholar and plans on remaining in this lab to complete her Senior Capstone Honors Thesis. Muzdalifa is also actively involved in the Douglass community as a Red Pine Ambassador, Douglass Summer Orientation Leader, Douglass Orientation Committee Member, and a Douglass Project Mentor. She also volunteers and shadows at the University Medical Center of Princeton at Plainsboro. Her future plans involve attending medical school.

Jessica Beck | Advisor: Dr. Nina Fefferman Higher Order Analysis of Social Learning in African Elephants

African Elephants (members of the genus Loxodonta) exhibit tiered social networks with fissionfusion dynamics. Knowledge is disseminated through these networks via group social learning. Elephants rely on information flow in order to make decisions when faced with novel challenges, but poaching of matriarchs, who serve as knowledge repositories, has limited the capacity for knowledge transfer. It is therefore important to study how knowledge dissemination changes following the loss of key individuals. Traditionally, computational models created to understand the percolation of information and potential limitations to communication in social networks are simplified by representing all communication in a pairwise manner. However, given the group dynamic of elephants, higher order analysis is necessary to fully understand the limitations of knowledge transfer. A newly developed framework relying on simplicial sets from algebraic topology is being implemented to more efficiently analyze n-way elephant communication and knowledge transfer.

Victoria Bowers | Advisor: Dr. Suzie Chen Preparing Mass20 Melanoma Clones to express Green Fluorescent Protein

Melanocytes are cells that are responsible for eye and skin pigmentation. Melanoma is the abnormal proliferation of melanocytes. An estimated over 76,000 new cases of melanoma will be diagnosed in 2014 and the 10-year survival rate for patients with metastatic melanoma is less than 10%. Therefore, a better understanding of the molecular mechanisms of metastatic melanoma development is necessary to development improved treatment options. Previously, Dr. Suzie Chenâ&#x20AC;&#x2122;s lab has demonstrated the ectopic expression of a neuronal receptor, metabotropic glutamate receptor 1 (Grm1) in melanocytes is sufficient to induce transformed melanocyt in vitro and spontaneous melanoma development in vivo. Grm1, is a member of the seventransmembrane G-protein coupled receptor family. Grm1 is normally expressed in the central nervous system with glutamate being its natural ligand and involves in learning and memory. Using cultured mouse melanocytes as a model system to elucidate the underlying mechanisms of Grm1mediated glutamatergic signaling in melanoma metastasis, we set out to construct green or red fluorescence tagged Grm1-transformed mouse melanocytes. We will use these fluorescencetagged cells to monitor the progression of the implanted transformed melanocytes in vivo by using a small animal imaging system, IVIS. Victoria Bowers is a third-year student in the School of Arts and Sciences pursuing a major in Genetics with a minor in Spanish. She has been working in Dr. Chenâ&#x20AC;&#x2122;s lab since January 2014. Victoria is interested in continuing her academic career into graduate school to get a PharmD. She involved both on and off campus, being a certified pharmacy technician at a Walgreens, the administrative manager of Douglass Residential Collegeâ&#x20AC;&#x2122;s Red Pine Ambassadors, as well as a member of the Rutgers Ultimate Frisbee Team. In her spare time she enjoys reading, volunteering, and snowboarding.

Aneesha Cheedalla | Advisors: Dr. Janet Alder and Dr. Smita Thakker-Varia Analyzing the effects of VGF on Spine Morphology

VGF (non-acronymic) is a neuropeptide that increases dendritic outgrowth and the number of spines on dendrites when transfected into hippocampal neurons. Molecules that increase the number of spines show higher amounts of filopodia. Therefore, VGF is thought to increase the amount of filopodia in hippocampal neurons along with the previously observed overall increase in dendritic spines. When infected with AAV vectors containing the VGF gene, hippocampal neurons show an increase in dendritic spines and a slight increase in spines of all different morphologies.

Aneesha Cheedalla is a junior in the School of Arts and Sciences majoring in Cell Biology and Neuroscience and minoring in Political Science.

! ! ! ! Schizophrenia (SZ) is a detrimental widespread neurological disorder that affects 1% of the worldâ&#x20AC;&#x2122;s population ! and for which there is no cure. There is strong evidence linking SZ to the abnormal activity of three neuronal populations: cortical glutamatergic neurons, gamma-aminobutyric acid ! (GABA)ergic neurons, and midbrain dopaminergic (mDA) neurons. Studies currently show that ! reduced glutamatergic input onto GABAergic neurons may contribute to disease, though it is unknown whether defects in glutamatergic neurons are the causal factor that first contribute to ! disease initiation. Methods to differentiate human induced pluripotent stem cells (hiPSCs) to ! neurons have been developed, but these methods generate heterogeneous neural populations that produce astrocytes, ! neural precursors, and non-neural cells alongside neurons. To improve these slow and inefficient methods, we are adapting viral transfection to overexpress key subtype-specific ! neuronal genes, an approach that appears to accelerate neuronal differentiation and also has the potential to!yield pure populations of glutamatergic neurons. By rapidly generating pure populations of glutamatergic neurons from schizophrenia patients and healthy controls, we hope to develop a ! platform with which to compare the cell autonomous contributions of glutamatergic neurons to this devastating!disease, and discover for the first time whether defects in glutamatergic neuron activity are primary!to schizophrenia. ! !

! ! ! Melanoma is ! a form of skin cancer that begins in the melanin-producing melanocytes. Itâ&#x20AC;&#x2122;s estimated that in 2014, there will be 76,100 new cases of melanoma in the United States. Recent studies have established!a link between microvesicles, exosome, production and increased tumor metastasis. In general, tumor ! cells release these microvesicles more frequently than normal ones. Exosomes may promote communication within the local microenvironment and the primary tumor, and sustain ! tumor cell dissemination and the early events in metastasis. Aberrant expression of metabotropic glutamate receptor ! 1, GRM1, in melanocytes led to dysregulated glutamatergic signaling, which has been implicated in melanoma pathogenesis and may influence exosome formation. We introduced ! exogenous GRM1 into human melanoma cell lines with either modest GRM1 expression level or ! absence of detectable GRM1 expression, these cells with enhanced GRM1 expression led to upregulated!angiogenesis and tumorigenesis in vitro and in vivo. To determine the relationship between GRM1, its subsequent signal transduction cascades and the production of exosomes, we utilized both! cultured cells and melanoma prone transgenic mouse model, TGS. Preliminary results showed that!the pharmalogical modulation in GRM1 function or expression resulted in a reduction in exosome levels and increased levels of exosome formation correspond to elevated GRM1 ! expression levels. ! !

! ! ! ! Varicosity formation in dendrites and loss of dendritic spines are early indicators of glutamate ! induced excitotoxicity. N-methyl-D-aspartate ((NMDA) acts as an agonist for the glutamate receptor. Hence, application of sublethal doses of NMDA to neurons induces the influx of sodium ! and chloride ions resulting in the formation of varicosities and the retraction of dendritic protrusion along the length ! of a dendrite. In this study, we utilize an optical scatter imaging method based on Fourier filtering to characterize the orientation changes of subcellular structures within neurons, that ! of NMDA treatment with high sensitivity and objectivity. Using a liquid crystal arise as a result device(LCD)!for Fourier filtering, twenty one Gabor filters were implemented at eight different orientations from 0o to 315o in increments of 45o to give a total of 168 Gabor filters. Scattering signals from!the neurons were then filtered at this conjugate Fourier plane and captured on a CCD camera. Analysis using an orientedness parameter, that measures the degree of elongation of ! cellular objects was then carried out on the Gabor filtered images by finding the ratio of the maximum to ! the average intensity over all the filter orientations employed. Our results tend to show a decrease in the orientedness values at time points after treatment and this decrease in ! values is slightly more apparent along the dendrites than in the cell bodies. Using our orientedness optical scatter ! imaging method, we investigated optical scatter responses from silicone membrane substrates. By conducting this study, we aim to determine the optimum filtering protocol to be ! studying the mechanical injury response of neurons injured via silicone membrane employed when stretching. ! !

CRISPR method were the following: sec-10, ipla-1, sdpn-1, let-23, tgn-38, and sma-6. The hTAC gene was successfully tagged with GFP; two homozygous strains exhibiting GFP expression have been isolated and will be frozen for future analysis. The CRISPR/Cas9 method did not yield GFP tagged genes suggesting that microparticle bombardment may not be optimal for this technique. A different delivery method, microinjection, may improve the delivery of the plasmids to the endogenous loci. CRISPR/Cas9 may prove to be more effective at fluorescent tagging due to its ability to precisely edit the genome, versus the random integration of the GFP gene during microparticle bombardment.

! ! ! Taste is an essential ! factor in a person’s decision to consume food. The fungiform papillae (FP) on the tongue contain taste buds, which are the main sense organ of taste and help guide a person’s ! foods. Previous studies have used a live visual or photographic method to count FP to responses to correlate their ! number with taste responses and with variations in taste genes [1]. Recent literature has suggested that other quantitative measures related to FP such as papillae size, density, and ! distance among FP could be correlated to taste perception and variation in related genes [2,3]. The goal of this project ! was to develop a methodology that would create a life-size, high resolution tongue impression that accurately reflects all of the anterior lingual papillae.

In this portion of the project, one diblock ! copolymer of polyethylene glycol—polylactic acid (PEG-PLA) was attached to each cowpea mosaic virus (CPMV)! capsid. Utilizing a highly coarse-grained system, two hundred and sixteen capsids were analyzed ! over five different volume fractions, ranging from 0.01 to 0.05.

This data includes extensive research on!its use as a drug delivery carrier in the form of hydrogels, nanoparticles, and micelles. The results of the study are in qualitative agreement with these previously-recorded studies, with ! PLA-centered micelles being formed in all volume fractions. It was found that this self-aggregation occurred for!all volume fractions within 30,000 tau—in which one tau is ~0.1997 nanoseconds; however, more dense systems appear to have equilibrated to a lower energy level and formed ! larger clusters.

! ! ! To determine ! the radius of a proton, physicists take advantage of electron scattering and muon scattering. However, the experimental results from recent electron scattering and muon scattering ! did not agree with each other. In this part of the research project, the group experiments investigated!whether there is an effect of point target assumption, which had been used in previous solid angle calculations to simplify the problem in muonic experiments. Solid angle values are ! important to know for estimating the time needed to run the scattering experiment. Since in the real world the ! target being hit by muonic signals is a three-dimensional object, the group studied the change of solid angles when the target is extended in x, y and z direction. Comparing the ! behavior of each kind of extended target with a point target for different kinds of targets allowed observation!of the differences made in extending the target in the axial directions. However, the overall effect of the extended targets are cancelled out when averaging the result of all the points ! on the targets. At the end, significant numbers of random points are generated using ROOT, a ! language created at CERN, to simulate the overall solid angle result from the programming extended target.

! ! ! Methoxychlor ! (MXC) is a pesticide that was previously used to replace DDT because of the harmful effects it had on wildlife and human populations. MXC is an endocrine disrupting chemical (EDCs) ! and an environmental estrogen, which is a compound that can bind to estrogen receptors and mimics estrogenâ&#x20AC;&#x2122; ! s effects. When exposed to MXC, it affects the reproductive system and the endocrine system of the body in both males and females. For this study, we specifically looked at ! male wild type mice to see how MXC affects gene expression in the arcuate nucleus of the hypothalamus, ! the area of the brain that controls reproduction and energy balance. The three treatments that were given were MXC low dose (MXC LD: 1 mg/kg/d), MXC high dose (MXC HD: 10 ! mg/kg/d) and oil. The genes that were analyzed were POMC, CART, AgRP, and NPY. However, the ! had significant data was POMC. For the POMC gene, there was a higher gene only gene that expression in MXC LD and MXC HD than in the oil. When the mice were exposed to MXC, POMC ! gene expression increased presumably due to activation of estrogen receptors (ER) in the neuron. ! !

! ! !There are approximately 500,000 bone grafting procedures performed annually in the United States. ! Autografts (patient’s own donated tissue) and allografts (tissue donated from cadavers) are the most common bone grafting!procedures, however, autografts requires two painful surgeries and allografts can lead to an adverse immunologic response. Therefore, tissue engineered grafts are a promising alternative with limited ! drawbacks. Tissue engineered bone scaffolds require an adequate amount of calcium phosphate, the inorganic ! bone, in order for bone tissue to repair and regenerate properly. However, current methods used component of Isabel Perez | Advisor: Dr. Joseph Freeman Electrodeposition Mineralization

to mineralize scaffolds, such as static mineralization and flow mineralization, are time consuming and do not provide uniform mineralization throughout scaffolds. Electrodeposition mineralization is a method that can provide an ideal amount of mineralized scaffolds in a shorter period of time, by utilizing an electric field to actively force mineral ions throughout a tissue engineered scaffold. Electrospun poly(d,l-lactide) (PDLA)/poly(llactide) (PLLA) with 10% gelatin scaffolds were created with sodium chloride (NaCl) crystals leached pores. The scaffolds were then mineralized in a simulated body fluid (SBF) solution for 2 hours via electrodeposition mineralization (5V, 10V, and 15V) and static mineralization for the control samples. Static mineralized scaffolds were submerged in SBF solution and in a static state for 2 hours. Alizarin red staining and ash weight analysis were performed in order to qualitatively and quantitatively assess the content amount of mineral deposited onto the scaffold by each mineralization method. Alizarin red forms a complex with calcium deposits which can be qualitatively observed and then quantitatively through an absorbance reading. The electrodeposition mineralized scaffolds were bright red, while the static mineralized scaffolds were a light pink, indicating that electrodeposition mineralized scaffolds had more calcium phosphate. The percent mineralization values were also obtained from the ash weight analysis for scaffolds mineralized at 5V, 10V, 15V and static Electrodepostion mineralization at 5V yielded the highest percent mineralization at 8.51±4.20% followed by10V, 15V,and static conditions at 4.37±2.15%, 7.63±1.60%, and 2.91±1.54%, respectively. The results of this study conclude, electrodeposition mineralization has a promising future in bone tissue engineering as a mineralization method that provides high calcium phosphate content with uniform deposition in a relatively short period of time. Future work will include scanning electron microscopy images of mineral throughout scaffolds and mineralization of scaffolds with different thickness for different periods of time to evaluate the effect the scaffold thickness on mineral deposition and view the rate of mineralization changes over time.

! ! ! Lumbosacral ! Spinal Cord Injury (LSCI) makes up about 1/3 of all spinal cord injuries in the world and results in damage to the spinal roots at the T11-L1 junction. Damage at this region affects the movement !and control of all bodily muscles and functions from the waist down. Even with its paralyzing effects ! and its rate of occurrence around the world, a treatment for lumbosacral spinal cord injury is barely being researched around the world. At the W.M. Keck Center for Collaborative ! Neuroscience, one of the only labs actively researching to find a treatment for LSCI, the project has been divided ! into two objectives. The first objective is regenerating motor neurons at the site of injury and the second objective is to promote the growth of new nerve connections from those ! neurons to the atrophied muscles.

! ! ! ! Histone deacetylases (HDACs) belong to a family of enzymes that function in inhibiting ! and as a result repressing gene expression. While HDACs are commonly found in the transcription nucleus of neurons, in vivo studies have shown that HDAC1, class I HDAC, may play a role in axonal ! pathology following traumatic brain injury. Using Controlled Cortical Impact (CCI) as a traumatic brain injury !model, our lab is focused in investing the role that various types of HDACs may play post traumatic ! brain injury. We have been able to observe increased expression of HDAC1 near the injury site prior to the beading of the axons following trauma. This supports previous studies ! suggesting the role of HDACs in axonal pathology, morphology and also its role in cell death. In addition we!have been able to provide evidence for the expression of HDAC7, a class II HDAC, in activated microglia and astrocytes on the ipsilesional side of injury, compared to no observed ! expression on the contralesional side of injury.

! ! ! Neurons are!responsible for communication within the nervous system. They exchange information via synaptic connections and therefore allow nerve cells to interact. The outputs are then transmitted!through a long, thin, membranous extension of the cell, the axon, which receives input from branched ! membranous extensions of the cell called dendrites. Through this network of axons and dendrites, a single neuron is able to receive input from many presynaptic cells. Neurobiologists ! wonder why how neurons find their specific synaptic partners, about the specialized machinery that Reshma Vohra | Advisor: Dr. Chris Rongo Neurite Regulation in C. elegans

creates these structures, and much more regarding the process of axon guidance. The Rongo lab is studying axon guidance using the genetic model system C. elegans. In C. elegans, command interneurons are neurons with cell bodies in the head of the worm that send out single fibers (neurites) along the ventral midline. In a previous study, they found that the E3 ubiquitin ligase RPM-1 inhibits excessive neurite overgrowth of the command interneuron AVG by repressing the activity of p38 MAP Kinase (MAPK) signaling. In addition, they found that JNK Kinase signaling also inhibits excessive AVG neurite outgrowth. Finally, they found a role for the WNT signaling pathway in promoting AVG neurite outgrowth. We currently do not know how these different pathways interact with each other. Our research experiments served to examine the interaction between these pathways by generating double mutants and quantifying their neurite outgrowth phenotype.

! ! ! Methylation!and hydroxymethylation at CpG dinucleotides in genomic DNA are two epigenetic modifications central to gene silencing and mammalian development. These epigenetic marks ! for embryogenesis and stem-cell differentiation in the germ line. DNA serve as regulators methyltransferases ! (DNMTs) are enzymes that transfer a methyl group from the cofactor Sadenosyl-L-methionine onto the 5-carbon position of a cytosine residue. Ten eleven translocation ! proteins (TET) use the 5-methyl cytosine (5-mC) as a substrate and change it to 5-hydroxymethyl cytosine (5-hmC), ! which constitutes the first step in demethylation. Although in vertebrates, 5-mC is a small percent of all cytosine residues in the genome, in invertebrates like Drosophila ! melanogaster, the level of methylation on DNA is orders of magnitude lower and often ! In order to study the role of 5-mC and 5-hmC in Drosophila, we induced expression undetectable. of the mouse de novo DNMT3A gene using the Gal4 system. Both Gal4 lines tested, daughterless! Gal4 and heatshock-Gal4, resulted invariably in pupal lethality. The elevated level of methylation ! by immunostaining and detection of 5-mC on salivary gland polytene was confirmed chromosomes. The loss in viability as a consequence of the transgeneâ&#x20AC;&#x2122;s expression implies that the ! high amount of methylation is not native to Drosophila. Because flies have an enzyme similar to DNMT2 and!in wild type flies there is virtually no methylation detectable on DNA, it is unlikely that DNMT2 is a !DNA methyltransferase and instead may function as an RNA methyltransferase. Additionally, to gain more perspective on the interaction between TET and DNMT in Drosophila, we performed a!developmental Western blot.
