From different investigation and proof gave by analyst and author work on pathophysiological part of TRPC 6 and the medications which modify or restrain TRPC6 or its downstream molecular target propose that TRPC6 is novel molecular target. Recently distinguished ROS/TRPC6 pathway will cover the best approach to new, reassuring restorative systems to target kidney ailments, especially Diabetic Nephropathy. Key-words- Diabetic nephropathy, TRPC6, Podocyte Injury, Proteinuria INTRODUCTION Transient receptor potential (TRP) channels are a large family of proteins with six main subfamilies named as TRPC (canonical), TRPV (vanilloid), TRPM (melastatin), TRPP (polycystin), TRPML (mucolipin), and TRPA (ankyrin) sets [1] . Classification on the basis of Amino acids Mammalian TRP channel proteins form six transmembrane cation-permeable channels that may be clustered into six subfamilies on the basis of amino acid arrangement (TRPC, TRPV, TRPM, TRPA, TRPP, and TRPML) [2] . Many TRPs are expressed in kidney along diverse parts of the nephron and growing confirmation propose that these channels are tangled in hereditary, as well as acquired kidney disorders [2] . The total number of different TRPs with diverse functions supports the announcement that these channels are tangled in a wide range of processes ranging from distinguishing of thermal and chemical signals to reloading intracellular stores after responding to an extracellular stimulus. Mutations in TRPs are associated to pathophysiology and specific diseases [1] Pathophysiological role of Transient Receptor Potential (TRP) Channels TRP melastatin (TRPM2) non-selective cation channels are expressed in the cytoplasm & intracellular organelles, Access this article online Quick Response Code Website: www.ijlssr.com DOI: 10.21276/ijlssr.2017.3.5.8 where their inhibition ameliorates ischaemic renal pathology [3] . TRPV4 may function as an osmoreceptor in kidney and participate in the regulation of sodium and water balance [2] . TRP vanilloid 4 receptor channels (TRPV4) are highly expressed in the kidney, where they induce Ca 2+ influx into endothelial and tubular cells. [3] TRPV5 contributes to several acquired mineral dysregulation, such as diabetes mellitus (DM), acid-base disorders, diuretics, immunosuppressant agents, and vitamin D analogues-associated Ca 2+ imbalance [2] . TRPC6, TRPM6, and TRPP2 have stayed associated in hereditary focal segmental glomerulosclerosis (FSGS), hypomagnesemia with secondary hypocalcemia (HSH), and polycystic kidney disease (PKD) [3] . Transient receptor potential cation channel, subfamily C, member 6 (TRPC6) in podocytes is tangled in chronic proteinuric kidney disease, mainly in focal segmental glomerulosclerosis (FSGS) [3] . TRPM6, located mainly in distal convoluted tubules, appears to be a vulnerable molecule that causes hypermagnesiuric hypomagnesemia as a tubulointerstitial nephropathy-independent altered tubular function in diabetic nephropathy [4] . Role in Kidney: Associates of the transient receptor potential (TRP) cation channel receptor family have unique sites of regulatory function in the kidney which allows them to promote local vasodilatation and controlled Ca 2+ influx into podocytes and tubular cells [3] . Renoprotection Animal Study: Triggered TRP vanilloid 1 receptor channels (TRPV1) have been found to elicit renoprotection in rodent models of acute kidney injury subsequent ischaemia/reperfusion.
