    Gut microbiota induced epigenetic alterations in type 2 diabetes mellitus

    Gut microbiota is implicated as an epigenetic factor contributing to chronic diseases such as obesity and diabetes. These indigenous microbiota produce multiple low-molecular weight substances that can interact with different targets in the cells, tissue, organs and organism on the whole.The major focus of my study will be to delineate genetic and epigenetic mediated regulation of gene expression in pancreatic cells by metabolites of gut microbiota.

    Molecular Pathogenesis of Varicose Veins

    Varicosity of lower limb veins is a multifactorial and heritable disease. The genetic basis and molecular mechanisms underlying the pathogenesis and progression of varicose veins are obscure. The aim of this study is to elucidate the genetic factors associated with the pathogenesis of primary varicose veins.
