Mechanisms of insulin secretion

Our laboratory is interested in the study of the KATP-independent anionic mechanisms of insulin secretion and how widely used diuretics impact the ability of pancreatic islets to secrete insulin and regulate carbohydrate metabolism.

Our research is primarily focused on the molecular biology, gene expression and the regulation of ion transporters targeted by diuretics and recently developed drugs. We are also interested in the impact of those drugs and their targets on insulin secretion in vitro and in vivo. Basically, our interests are centered at the molecular mechanisms involved in the regulation of transporters' gene expression, the intracellular signaling networks leading to transcriptional or post-transcriptional modulation of their expression and function and how these mechanisms interact to modulate insulin secretion in response to nutrients. We use animal or cellular models, which have been genetically modified to lack or over express genes of interest. We routinely use functional methods to assess glucose homeostasis, tissue function and hormone secretion. Our research hypotheses are routinely tested at several levels using functional, pharmacological, genetic and molecular approaches such as those involving th euse of the polymerase chain reaction (PCR), reverse transcription coupled to conventional or quantitative  PCR, cloning, sub-cloning, site directed mutagenesis, molecular tagging, gene silencing, gene over expression, immunological and imaging techniques.
