Role Of Retinoids In The Regulation Of Hepatic Glucose And Lipid Metabolism, Rui Li
Role Of Retinoids In The Regulation Of Hepatic Glucose And Lipid Metabolism, Rui Li
Doctoral Dissertations
The liver plays an important role in controlling glucose and lipid homeostasis. Metabolic abnormalities such as obesity and type 2 diabetes are often associated with profound changes in the expression of genes involved in hepatic glucose and lipid metabolism. Dietary nutrients provide us with macronutrients for energy and micronutrients for maintenance of general health. However, the effects of individual micronutrients on the development of metabolic diseases are unknown. Sterol regulatory element binding protein-1c (SREBP-1c) is the master regulator of fatty acid synthesis, and glucokinase (GK) is the key enzyme in glucose metabolism. Based on the preliminary results from our laboratory …

Angiotensinogen Gene Silencing Reduces Lipid Accumulation And Inflammation In Cultured 3t3-L1 Adipocytes, Wenting Xin Carroll
Masters Theses
Obesity is characterized by metabolic complications which are related to several life-threatening diseases. Dysregulated inflammatory adipokines secretion from adipose tissue is believed as the major contributor to obesity-associated local and systemic inflammation, insulin resistance, and other metabolic dysfunctions.
Numerous studies in our lab and others pointed to the role of local adipose tissue renin-angiotensin system (RAS) in the pathogenesis of obesity, inflammation and insulin resistance. We hypothesized that adipocytes-derived angiotensinogen (Agt) played a critical role in adipogenesis and/or lipogenesis as well as adipose inflammation. To test, we established 3T3-L1 preadipocytes stably transfected with Agt-shRNA or scrambled sequence (Sc-shRNA). Transfected preadipocytes …

The peroxisome proliferator-activated receptor gamma (PPARgamma) is a nuclear transcription factor that controls the genes involved in metabolism and carcinogenesis. In the present study, we examined the alteration of gene expression in HCT-116 human colorectal cancer cells by PPARgamma agonists: MCC-555 (5 microM), rosiglitazone (5 microM), and 15-deoxy-Delta12,14-prostaglandin J2 (1 microM). The long-oligo microarray data revealed a list of target genes commonly induced (307 genes) and repressed (32 genes) by tested PPARgamma agonists. These genes were analyzed by Onto-Express software and KEGG pathway analysis and revealed that PPARgamma agonists are involved in cell proliferation, focal adhesion, and several signaling pathways. …
