    The research program of Dr Claing aim at studying the molecular mechanisms regulating cellular responses following stimulation of the largest family of trans-membrane receptors, the G protein-coupled receptors. These proteins are the targets of more than 40% of the drugs sold today. The detailed study of the signaling pathways activated by receptors following their stimulation by a broad variety of stimuli ranging from the light to hormones have allowed Dr Claing\u2019s group to reveal the important role of a family of proteins named ADP-ribosylation factors (ARFs). These act like molecular switches to control remodeling of the actin cytoskeleton, transformation of plasma membrane lipids and the process of vesicle formation. Elucidation of the molecular events leading to the activation of ARF proteins as well as the signaling pathways regulated by the GTPases are the main focus of this laboratory. Cellular models used include breast cancer and endothelial cells. The demonstration that ARF proteins are key regulators of intracellular signals activated by membrane receptors will contribute to demonstrate that these proteins are potential new therapeutic targets.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
