Pharmacogenetics is the study of genomic-guided individualized drug prescription that plays an important role in preventing the severe adverse effects of drugs, decreasing the time and cost of therapeutic choices, and directing healthcare professionals to choose medications that are effective and safe. It is noteworthy that this approach becomes highly beneficial in patients suffering from chronic diseases or disorders, since these conditions may require multiple and long term pharmacological therapies, as in children with autism spectrum disorder (ASD). However, public acceptance is a major challenge when implementation of pharmacogenetics merges into clinical practice. The purpose of this study is a) …

Perinatal Malnutrition And Epigenetic Regulation Of Long-Term Metabolism In The Liver And Adipose Tissue, Daniel B. Hardy
Physiology and Pharmacology Publications
Maternal malnutrition in perinatal life can have long-lasting adverse effects on glucose and lipid homeostasis in the offspring, culminating in dyslipidemia, insulin resistance and obesity. Understanding the molecular mechanisms underlying how these nutritional deficits during perinatal life lead to permanent changes in hepatic and adipose function will provide efficacious therapeutic strategies to mitigate these metabolic defects short- and long-term. This chapter addresses how epigenetic mechanisms mediate alterations in hepatic and adipose gene expression identified from clinical studies and different experimental models of maternal malnutrition. These include DNA methylation, post-translational histone modifications, and microRNAs.

On December 18, 2015, President Obama signed into law a policy rider forestalling the therapeutic modification of the human germ line. The rider, motivated by the science’s potential unethical ends, is only the most recent instance in which the legislature cut short the ongoing national conversation on the acceptability of a developing science. This essay offers historical perspective on what bills were proposed and passed surrounding four other then-developing scientific breakthroughs—Recombinant DNA, in vitro fertilization, Cloning, Stem Cells—to better analyze how Congress is, and should, regulate this exciting and promising science.

Aging, Executive Function, Fronto-Parietal Network Cortical Thickness: Insights From Cognitive Reserve, Katherine Reiter
Dissertations (1934 -)
Cognitive reserve (CR) indexes the nonlinear relationship between neurological insult and behavioral change. CR is manifested in both static factors (e.g., childhood environment, education) and modifiable lifestyle factors, (e.g., leisure activities). Detailed investigation of the influence of CR on cortical thickness, which indexes neuropathology, and cognitive functioning could be particularly important in understanding the heterogeneity of Alzheimer’s disease (AD). While memory decline is the hallmark of AD, executive functioning (EF) decline often predates memory changes, making EF an important target for investigating CR influences. The current study examines the relationship of CR and genetic risk for AD (ε4) on EF …

The Neural Encoding Of Reward In The Striatal-Pallidal Circuitry, Chung Lung Chan
Dissertations (1934 -)
Humans and animals are constantly exposed to external stimuli. The ability to process reward value of a stimulus is critical to guiding appropriate behavior and essential for survival. These processes are regulated by neuronal activity and neurochemical signaling in the reward circuitry, particularly in the nucleus accumbens (NAc). The NAc receives dopaminergic inputs from the midbrain ventral tegmental area (VTA) and sends GABAergic projections to the ventral pallidum (VP). Electrophysiological studies have characterized phasic neuronal responses in the NAc that differential encode appetitive and aversive taste stimuli. Exposure to an appetitive taste stimulus evoked predominantly phasic inhibitory responses in the …

Neuromuscular Function In Women Postpartum, Rita Deering
Dissertations (1934 -)
Efficient abdominal muscle function is important for functional mobility in men and women, and dysfunction of these muscles has been associated with impaired function such as low back pain. This dissertation explored abdominal muscle function in healthy young men and young women who have never been pregnant (nulligravid). As pregnancy and child birth also impact the tissues of the abdominal wall, this dissertation will also explore abdominal muscle function in postpartum women. This dissertation involved three primary aims. Aim1 compared abdominal muscle function and experimental pain perception in males and nulligravid females. Maximal strength over a range of trunk angles, …

G-protein-coupled receptors (GPCRs) are increasingly recognized to operate from intracellular membranes as well as the plasma membrane. The β 2 -adrenergic GPCR can activate G s -linked cyclic AMP (G s -cAMP) signaling from endosomes. We show here that the homologous human β 1 -adrenergic receptor initiates an internal G s -cAMP signal from the Golgi apparatus. By developing a chemical method to acutely squelch G-protein coupling at defined membrane locations, we demonstrate that Golgi activation contributes significantly to the overall cellular cAMP response. Golgi signaling utilizes a preexisting receptor pool rather than receptors delivered from the cell surface, requiring …

The presence of multivessel coronary artery disease (CAD) is strongly associated with higher 30-day mortality, reduced myocardial reperfusion success, reinfarction, and occurrence of major adverse cardiac events (MACE) at 1 year compared with single-vessel CAD. Despite higher morbidity and mortality in patients with ST-elevation myocardial infarction (STEMI) and coexistent multivessel CAD, major guidelines recommended against percutaneous coronary intervention (PCI) on non-culprit lesions at the time of primary PCI in patients with STEMI who are hemodynamically stable. The presence of multivessel CAD often poses a therapeutic dilemma for interventional cardiologists. A few larger scale randomized controlled trials (RCTs) and meta-analyses have …

linical challenges exist in reducing prostate cancer (PCa) disparities. The RNA splicing landscape of PCa across racial populations has not been fully explored as a potential molecular mechanism contributing to race-related tumour aggressiveness. Here, we identify novel genome-wide, race-specific RNA splicing events as critical drivers of PCa aggressiveness and therapeutic resistance in African American (AA) men. AA-enriched splice variants of PIK3CD, FGFR3, TSC2 and RASGRP2 contribute to greater oncogenic potential compared with corresponding European American (EA)-expressing variants. Ectopic overexpression of the newly cloned AA-enriched variant, PIK3CD-S, in EA PCa cell lines enhances AKT/mTOR signalling and increases proliferative …

Chloroanilines are widely used in the manufacture of drugs, pesticides and industrial intermediates. Among the trichloroanilines, 3,4,5-trichloroaniline (TCA) is the most potent nephrotoxicant in vivo. The purpose of this study was to examine the nephrotoxic potential of TCA in vitro and to determine if renal biotransformation and/or free radicals contributed to TCA cytotoxicity using isolated renal cortical cells (IRCC) from male Fischer 344 rats as the animal model. IRCC (~4 million cells/mL; 3 mL) were incubated with TCA (0, 0.1, 0.25, 0.5 or 1.0 mM) for 60–120 min. In some experiments, IRCC were pretreated with an antioxidant or a …

Sh2 Ligand-Like Effects Of Second Cytosolic Domain Of Na/K-Atpase Α1 Subunit On Src Kinase, Moumita Banerjee, Qiming Duan, Zijian Xie
Zijian Xie
Our previous studies have suggested that the α1 Na/K-ATPase interacts with Src to form a receptor complex. In vitro binding assays indicate an interaction between second cytosolic domain (CD2) of Na/K-ATPase α1 subunit and Src SH2 domain. Since SH2 domain targets Src to specific signaling complexes, we expressed CD2 as a cytosolic protein and studied whether it could act as a Src SH2 ligand in LLC-PK1 cells. Co-immunoprecipitation analyses indicated a direct binding of CD2 to Src, consistent with the in vitro binding data. Functionally, CD2 expression increased basal Src activity, suggesting a Src SH2 ligand-like property of CD2. Consistently, …

Candida pneumonia is a rare infection of the lungs, with the majority of cases occurring secondary to hematological dissemination of Candida organisms from a distant site, usually the gastrointestinal tract or skin. We report a case of a 77-year-old male who is life-long smoker with a history of rheumatoid arthritis and polymyalgia rheumatica, but did not take immunosuppressants for those conditions. Here, we present an extremely rare case of isolated pulmonary parenchymal Candida infection in the form pulmonary nodules without evidence of systemic disease which has only been described in a few previous reports.

Bone and skeletal muscle mass are highly correlated in mammals, suggesting the existence of common anabolic signaling networks that coordinate the development of these two anatomically adjacent tissues. The activin signaling pathway is an attractive candidate to fulfill such a role. Here, we generated mice with conditional deletion of activin receptor (ACVR) type 2A, ACVR2B, or both, in osteoblasts, to determine the contribution of activin receptor signaling in regulating bone mass. Immunohistochemistry localized ACVR2A and ACVR2B to osteoblasts and osteocytes. Primary osteoblasts expressed activin signaling components, including ACVR2A, ACVR2B, and ACVR1B (ALK4) and demonstrated increased levels of phosphorylated Smad2/3 upon …

Numerically Solving A System Of Pdes Modeling Chronic Wounds Treated With Oxygen Therapy, Stefan Stryker
Mahurin Honors College Capstone Experience/Thesis Projects
Chronic wounds such as diabetic foot ulcers are the leading cause of non-traumatic amputations in developed countries. For researchers to better understand the physiology of these wounds, a mathematical model describing oxygen levels at the wound site can be used to help predict healing responses. The model utilizes equations that are modified from work by Guffey (2015) that consists of four variables – oxygen, bacteria, neutrophils, and chemoattractant within a system of partial differential equations. Our research focuses on numerically solving these partial differential equations using a finite volume approach. This numerical solver will be important for future research in …

Psychology: Faculty Scholarship
Corticotropin releasing hormone (CRH) produced by the hypothalamus initiates the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the body’s stress response. CRH levels typically are undetectable in human plasma, but during pregnancy the primate placenta synthesizes and releases large amounts of CRH into both maternal and fetal circulations. Notably, placental CRH synthesis increases in response to maternal stress signals. There is evidence that human fetal exposure to high concentrations of placental CRH is associated with behavioral consequences during infancy and into childhood, however the direct effects on of the peptide on the human brain are unknown. In this study, we used a …
