Studies in the Rameh Lab (http://sites.bu.edu/rameh-lab/) are aimed at understanding how phosphoinositide lipids affect different aspects of the diabetes/obesity cycle. As regulator of many cellular processes, such as vesicle trafficking and hormone signaling, phosphoinositide kinases are promising targets in the treatment of these diseases. The Rameh Lab is particularly interested in determining the role of the phosphoinositide PtdIns-5-P in pancreatic beta cell function. Recent data from the Lab show that PtdIns-5-P 4-kinases can regulate nutrient-independent TORC1 signaling that activates basal protein translation. They are currently investigating how these can impact basal insulin production and secretion in the pre-diabetic state. The Rameh Lab uses state-of-the art high performance liquid chromatography (HPLC) coupled to flow scintillation analysis to measure cellular phosphoinositides in cultured cells. They have recently developed a unique method for PtdIns-5-P detection that will aid future research on the cellular function of this lipid.
