Abstract:
Rho protein represents a family of small GTP binding proteins that are involved in many important cellular functions including cell proliferation, migration and cytoskeletal reorganization. Rho protein is activated by GTP binding and is inactivated by hydrolyzing GTP to GDP. This process is influenced by variety of physiological and pathophysiological stimuli including growth factors, many vasoactive substances, smoking and mechanic stress or injury. Recent evidence suggest that targeting Rho protein per se or its downstream effector proteins such as Rho kinase or LIM kinase may have therapeutic potential in diseases such as hypertension, angina, myocardiac infarction (MI), atherosclerosis, tumor metastasis and spinal cord injury. Several recent patents have described modalities that regulate the activity of Rho, Rho kinase and LIM kinase as potential therapeutics. In this article, we will review the current knowledge on the cellular functions of Rho signaling pathway and strategies in targeting different components in Rho signaling pathway for human diseases with an emphasis on cardiovascular indications.

Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
