The Epigenetic Impact Of Dietary Choline On Growth Outcomes Of Children Exposed To Gestational Diabetes Mellitus, Ismail Kadam

Dissertations, Theses, and Capstone Projects

Maternal insulin resistance and hyperglycemia lead to gestational diabetes mellitus (GDM) which can cause fetal hyperinsulinemia, ultimately leading to excessive fetal growth associated with macrosomia and increased adiposity at birth. Increased placental macronutrient transport and epigenetic changes in growth and metabolic genes affected by GDM contribute to fetal overgrowth and can result in complications such as overweight/obesity, insulin resistance/type 2 diabetes, cardiovascular disease risk factors, as well as cognitive impairment later in life. Choline, an essential nutrient, participates in lipid and energy metabolism by providing methyl groups for DNA methylation and thus may overcome the hypomethylation of growth and metabolic …

The crosstalk between clathrin-mediated endocytosis (CME) and the autophagy pathway has been reported in mammals; however, the interconnection of CME with autophagy has not been established in plants. Here, we report that the Arabidopsis CLATHRIN LIGHT CHAIN (CLC) subunit 2 and 3 double mutant, clc2-1 clc3-1, phenocopies Arabidopsis AUTOPHAGY-RELATED GENE (ATG) mutants in both autoimmunity and nutrient sensitivity. Accordingly, the autophagy pathway is significantly compromised in the clc2-1 clc3-1 mutant. Interestingly, multiple assays demonstrate that CLC2 directly interacts with ATG8h/ATG8i in a domain-specific manner. As expected, both GFP-ATG8h/GFP-ATG8i and CLC2-GFP are subjected to autophagic degradation, and degradation of GFP-ATG8h is …

Light plays an essential role in a variety of physiological processes, including vision, mood, and glucose homeostasis. However, the intricate relationship between light and an animal's feeding behavior has remained elusive. Here, we found that light exposure suppresses food intake, whereas darkness amplifies it in male mice. Interestingly, this phenomenon extends its reach to diurnal male Nile grass rats and healthy humans. We further show that lateral habenula (LHb) neurons in mice respond to light exposure, which in turn activates 5-HT neurons in the dorsal Raphe nucleus (DRN). Activation of the LHb→5-HTDRN circuit in mice blunts darkness-induced hyperphagia, while inhibition …

Oxysterols are metabolites of cholesterol that regulate cholesterol homeostasis. Among these, the most abundant oxysterol is 27-hydroxycholesterol (27HC), which can cross the blood-brain barrier. Because 27HC functions as an endogenous selective estrogen receptor modulator, we hypothesize that 27HC binds to the estrogen receptor α (ERα) in the brain to regulate energy balance. Supporting this view, we found that delivering 27HC to the brain reduced food intake and activated proopiomelanocortin (POMC) neurons in the arcuate nucleus of the hypothalamus (POMCARH) in an ERα-dependent manner. In addition, we observed that inhibiting brain ERα, deleting ERα in POMC neurons, or chemogenetic inhibition of …

Exploring The Relationships Between Food Insecurity, Wic Participation, Early Life Feeding Practices, Diversity Of Dietary Exposures, And Diet Quality In The First Two Years Of Life, Vivian M. Drewelow

Master's Theses

Diet quality during early childhood is a strong predictor of mental and physical outcomes, as well as future diet quality. Although many factors determine diet quality during childhood, food insecurity is a significant predictor of lower diet quality. On the other hand, participation in nutrition assistant programs, such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a significant predictor of higher diet quality. In addition, specific feeding practices, including timing of complementary food and beverage (CFB) introduction, types of CFB introduced early, and diversity of dietary exposures (DD), in the first year may predict future …

An Estrogen Receptor Α-Derived Peptide Improves Glucose Homeostasis During Obesity, Wanbao Yang, Wen Jiang, Wang Liao, Hui Yan, Weiqi Ai, Quan Pan, Wesley A Brashear, Yong Xu, Ling He, Shaodong Guo

Faculty, Staff and Students Publications

Estrogen receptor α (ERα) plays a crucial role in regulating glucose and energy homeostasis during type 2 diabetes mellitus (T2DM). However, the underlying mechanisms remain incompletely understood. Here we find a ligand-independent effect of ERα on the regulation of glucose homeostasis. Deficiency of ERα in the liver impairs glucose homeostasis in male, female, and ovariectomized (OVX) female mice. Mechanistic studies reveal that ERα promotes hepatic insulin sensitivity by suppressing ubiquitination-induced IRS1 degradation. The ERα 1-280 domain mediates the ligand-independent effect of ERα on insulin sensitivity. Furthermore, we identify a peptide based on ERα 1-280 domain and find that ERα-derived peptide …

Targeting Glutamine Dependence With Drp-104 Inhibits Proliferation And Tumor Growth Of Castration-Resistant Prostate Cancer, David Moon, J Spencer Hauck, Xue Jiang, Holly Quang, Lingfan Xu, Fan Zhang, Xia Gao, Robert Wild, Jeffrey I Everitt, Everardo Macias, Yiping He, Jiaoti Huang

Faculty, Staff and Students Publications

BACKGROUND: Prostate cancer (PCa) continues to be one of the leading causes of cancer deaths in men. While androgen deprivation therapy is initially effective, castration-resistant PCa (CRPC) often recurs and has limited treatment options. Our previous study identified glutamine metabolism to be critical for CRPC growth. The glutamine antagonist 6-diazo-5-oxo-l-norleucine (DON) blocks both carbon and nitrogen pathways but has dose-limiting toxicity. The prodrug DRP-104 is expected to be preferentially converted to DON in tumor cells to inhibit glutamine utilization with minimal toxicity. However, CRPC cells' susceptibility to DRP-104 remains unclear.

METHODS: Human PCa cell lines (LNCaP, LAPC4, C4-2/MDVR, PC-3, 22RV1, …
