Research Interests

Type-2 Diabetes
Mechanisms of insulin secretion

Our laboratory is interested in the study of anionic mechanisms of insulin secretion and how widely used diuretics and other drugs impact the ability of pancreatic islets to secrete insulin and regulate carbohydrate metabolism directly or indirectly through the regulation of feeding behavior

Our research is primarily focused on the molecular biology, gene expression profile, regulation and physiology of chloride transporters and channels expressed in insulin-secreting β-cells. We are also interested in the role of drugs targeting those transporters and channels on the secretory response and glucose homeostasis. 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, how these mechanisms interact to modulate insulin secretion in response to nutrients and how primary changes in the secretory response affect satiation and satiety to control energy intake. We use animal or cellular models, which have been genetically modified to lack or over express gene/s 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, molecular and behavioral approaches such as those involving the use 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 or immunological imaging techniques and the real time measurement of satiation and satoety responses to food intake.
