[A] Epigenetic and cell signaling effects of ethanol on liver:

The effect of ethanol on cell signaling in liver cells (hepatocytes) is being investigated with the goal to identify the key steps altered by ethanol in (a) MAP kinase pathway and (b) in the nuclear responses. Proteomic analysis of the kinase substrates affected by ethanol is one of the issues being addressed. In the nuclear effects, the focus is on the chromatin histone modification(s) and the goal is to understand the molecular mechanism and transcriptional consequence of ethanol induced epigenetic histone modifications (i.e. acetylation, methylation and phosphorylation). The CHIP assay, gene and protein array technologies are being utilized to identify the ethanol affected genes and proteins relevant to alcoholic liver disease. The laboratory also uses pharmacological agents in animals/ in vivo for translational implications of these studies.

[B] Platelets and vascular remodelling:

The role of blood platelets and its secretory products in vascular responses is another topic of focus. We have established the pharmacological properties of platelet activating factor (PAF) and its receptor associated cell signaling responses in human and rabbit platelets. Our new observations show that upon activation, human platelets secrete specific PKC isozymes (PKC α, βII and δ). This raises the question of extracellular role of these PKCs on adjacent cells (eg. endothelial or smooth muscle cells) in the vasculature or at the site of injury where platelets adhere and secrete these isozymes. Diabetic platelets, which exhibit hypersensitivity, are being used to test whether secretion of these PKC’s have significance in the thromboembolic complications observed in diabetics.
