MCCANN Under the Direction of Kim Levy Huhman, PhD ABSTRACT Social stress is the most common stressor experienced by humans and exposure to social stress is thought to cause or exacerbate neuropsychiatric illness. Social stress also leads to behavioral and physiological responses in many animal models that closely mirror the symptoms of fear and anxiety in humans. Our laboratory uses Syrian hamsters to study behavioral responses to social stress. Hamsters are highly territorial, but after losing an agonistic encounter, hamsters exhibit a striking behavioral change, abandoning all territorial aggression and instead becoming highly submissive. This behavioral shift is termed conditioned defeat. Epigenetic modifications, such as changes in histone acetylation, are a possible molecular mechanism underlying such behavioral shifts. Histone deacetylase (HDAC) inhibitors have been shown to enhance fear learning and conditioned place preference for drugs of abuse, while suppressing histone acetylation with histone acetyltransferase (HAT) inhibitors impairs long-term memory formation. The first goal of this study was to test the hypothesis that histone acetylation is a molecular mechanism underlying conditioned defeat. We found that animals given an HDAC inhibitor systemically before social defeat later exhibited increased conditioned defeat. This treatment also suppressed defeat-induced immediate-early gene activity in the infralimbic cortex but not the basolateral amygdala. Next, we demonstrated that administration of an HDAC inhibitor in the infralimbic cortex before defeat enhanced stress-induced behavioral responses while HAT inhibition blocked these behavioral changes. Although both males and females exhibit conditioned defeat, the behavioral expression is more pronounced in males. We next used transcriptomic analysis to investigate potential genetic mechanisms leading to this sexually dimorphic expression and to further delineate the role of acetylation in stress-induced behavioral changes. We sequenced the whole brain transcriptome of male and female hamsters as well as the transcriptome of basolateral amygdala, a nucleus necessary for the acquisition and expression of conditioned defeat, of dominant, subordinate, and control animals. Our analysis revealed that numerous genes relating to histone acetylation, including several HDACs, were differentially expressed in animals of different social status and between sexes. Together, these data support the hypotheses that histone modifications underlie behavioral responses to social stress and that some of these modifications are sexually dimorphic.

Kim, you have been an amazing mentor, role model, and friend. I could not have asked for a better graduate school experience or a better advisor to help get me here. You have taught me so much about how to be a good scientist and how to keep a balanced life without sacrificing success. I am incredibly grateful that you took that chance on me all those years ago! I also want to thank the members of my committee, Dr. Elliott Albers, Dr. Laura Carruth, Dr. Kerry Ressler, and Dr. Walt Wilczynski. Thank you Elliott for being a second mentor to me all through graduate school. I am excited for the opportunity to continue to work with and learn from you over the next year. To Laura, thank you for teaching me the importance of being a well-rounded scientist. I am a better scientist because of your mentorship. To Walt and Kerry, I would not have made it this far without your support and guidance. I dove in head first to the world of epigenetics and transcriptomics, and I may have drowned had it not been for you both. I also want to thank all of the members of both the Huhman and Albers labs who have supported and helped me throughout this entire process, especially Alisa. Alisa – you know we would all be lost without you. Your help and guidance in the lab is invaluable, but more importantly, I am happy to have found a life-long friend. Furthermore, this work would not have been possible without the support of my friends and family, the GSU DAR staff, the NI administration, and GSU IS&T. Lastly, I would like to thank Ken and Georganne Honeycutt. Knowing that I had people as genuine and supportive as the Honeycutts rooting for me has made reaching the finish line so much easier. vi TABLE OF CONTENTS Acknowledgements ............................................................................ v List of tables ..................................................................................... xi List of figures ................................................................................... xii 1 Introduction ................................................................................. 1 1.1 Animal models of human psychopathology: Using hamsters in a translational model of social stress-induced behavioral change ............. 1 1.2 Epigenetic mechanisms underlying conditioned defeat: The potential role of histone deacetylases ....................................................... 4 1.3 Genetic resources for non-traditional animal models using transcriptomics ........................................................................................ 7 1.4 Specific aims overview............................................................. 9 1.4.1 Specific Aim 1: Does inhibition of HDACs or HATs increase or decrease, respectively, social avoidance and submissive behavior after acute social defeat? ...................................................................... 9 1.4.2 Specific Aim 2: Does systemic HDAC inhibition during social defeat increase subsequent neuronal activity (as measured by Fos-immunoreactivity) in specific nodes of the neural circuit that mediates conditioned defeat? ................................................................ 9 1.4.3 Specific Aim 3: Are Class I HDACs highly expressed in the hamster amygdala and is their expression altered by social defeat? .. 10 vii 2 Pharmacological manipulation of histone acetylation modulates behavioral responses to acute social stress ............................................... 10 2.1 Introduction .......................................................................... 10 2.2 Materials and Methods .......................................................... 12 2.2.1 Animals ........................................................................... 12 2.2.2 Social defeat training ...................................................... 13 2.2.3 Social avoidance testing .................................................. 14 2.2.4 Cannulation and microinjections .................................... 15 2.2.5 Pharmacological agents .................................................. 16 2.2.6 Histology.......................................................................... 17 2.2.7 Immunohistochemistry for immediate-early gene c-fos ... 17 2.2.8 Statistical analysis .......................................................... 18 2.3 Results .................................................................................. 18 2.3.1 Systemic administration of an HDAC inhibitor before social stress enhances the acquisition of conditioned defeat .............. 18 2.3.2 Systemic administration of VPA also enhances acquisition of conditioned defeat in female hamsters ............................................ 21 2.3.3 Site-specific HDAC inhibition in the IL, but not in the BLA, alters behavioral responses to social defeat ....................................... 21 2.3.4 HAT inhibition in the IL blocks the acquisition of conditioned defeat .............................................................................

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

Of the markers, 25 were placed on the USDA reference linkage map and 37 were positioned on the Roslin 3000-rad radiation hybrid (RH) map, with 20 assignments shared between the maps. Although no novel regions of conserved synteny between the cattle and the human genomes were identified, the coverage was extended for bovine chromosomes 3, 7, 15, and 29 compared with previously published comparative maps between human and bovine genomes. Overall, these data improve the resolution of the human–bovine comparative maps and will assist future efforts to integrate bovine RH and linkage map data.

Shortcomings of these studies were low mapping resolution, large confidence intervals for quantitative trait loci-positions and large linkage disequilibrium blocks. Here, we overcome these shortcomings by pooling four large F2 designs to produce smaller linkage disequilibrium blocks and by resequencing the founder generation at high coverage and the F1 generation at low coverage for subsequent imputation of the F2 generation to whole genome sequencing marker density.

The aim of the present study is to explore the database and functional annotation of NF-κB target genes. Methods: In this study, we manually collected the most complete listing of all NF-κB target genes identified to date, including the NF-κB microRNA target genes and built the database of NF-κB target genes with the detailed information of each target gene and annotated it by DAVID tools. Results: The NF-κB target genes database was established (http://tfdb.seu.edu.cn/nfkb/). The collected data confirmed that NF-κB maintains multitudinous biological functions and possesses the considerable complexity and diversity in regulation the expression of corresponding target genes set. The data showed that the NF-κB was a central regula- tor of the stress response, immune response and cellular metabolic processes. NF-κB involved in bone disease, immunological disease and cardiovascular disease, various cancers and nervous disease. NF-κB can modulate the expression activity of other transcriptional factors. Inhibition of IKK and IκBα phosphorylation, the decrease of nuclear translocation of p65 and the reduction of intracellular glutathione level determined the up-regulation or down-regulation of expression of NF-κB target genes.

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in
