Glucotoxicity is the leading cause for β-cell dysfunction [e.g., defective glucose-stimulated insulin secretion] in Type 2 Diabetes [T2DM]. Recent studies from our lab have shown sustained Rac1 activation leading to the activation of downstream signaling steps including stress kinase [p53, p38MAPK] activation and mitochondrial dysregulation [caspase-3 activation] in pancreatic islet beta-cells exposed to glucotoxic [HG] conditions [20 mM; 24 hrs]. Metformin [MF] is an oral anti-diabetic drug that is being widely prescribed to T2DM. MF works by suppressing hepatic …

Endocrine-Disrupting Properties Of Pharmaceuticals And Personal Care Products (Ppcps): An Evaluation Using Aquatic Model Organisms, Manahil Monshi

Wayne State University Theses

Thousands of chemicals have introduced into the environment as a result of human activity since the industrial revolution, and the U.S. Government Accountability Office has estimated that as many as 1,500 new chemical entities are synthesized each year ("Key Issues: Toxic Chemicals - High Risk Issue," 2017). Many of these chemicals are now found in surface water and ground water and can have detrimental effects on environmental health and on human health. This anthropogenic contamination has resulted in the labeling of the diverse array of chemicals found in water, which are not routinely monitored or regulated, as contaminants of emerging …

Patholigical And Prognostic Role Of Mdig In Pancreatic Cancer, Srinivas Ashok Kumar

Wayne State University Theses

Pancreatic cancer is a highly aggressive malignant disease having very limited therapeutic options that ultimately results in its poor prognosis. It is still elusive on the etiology and tumorigenic mechanisms of pancreatic cancer. In the present report, we provide evidence showing involvement of the mineral dust-induced gene (mdig) in the pathogenesis and prognosis of the pancreatic cancer. Using immunohistochemistry approach on human pancreatic cancer tissue microarray, we found differential expression of mdig in pancreatic adenocarcinoma and normal pancreas. Based on the staining intensities of mdig in these tissue samples, we found that 12% of the cancer tissues were strongly positive …
