Abstract:
Objective To explore the expression and distribution of transient receptor potential cation channel 6(TRPC6)in normal human,mice,rats' renal tissue and the mouse podocyte clone 5(MPC5)for further investigating the relationship between TRPC6 and the protei-nuria-related podocyte molecules.Methods 1.The distributions of TRPC6 in normal human,mice,rats' renal tissue and MPC5 were observed by using the immunochemistry staining.2.The mRNA expression of TRPC6 in mouse renal cortex and differentiated MPC5 was detected by using reverse transcriptase-polymerase chain reaction(RT-PCR).3.The protein expression of TRPC6 in human,mice and differentiated MPC5 was detected by using Western blotting.Results 1.In human kidney,TRPC6 showed a weak staining in glomeruli and a strong staining in renal tubules and vessels.In mice and rats' kidney,TRPC6 showed a strong staining in glomeruli and was mainly distributed along the capillary loops of glomerulus and in mesangium.The positive staining of TRPC6 was observed in MPC5,which was distributed evenly on the cell membrane in differentiated podocytes.2.The specific PCR band of TRPC6 was detected in mouse renal cortex and differentiated MPC5.3.The specific protein band of TRPC6 was detected in normal human,mice renal cortex and differentiated MPC5 with the size of 106.Conclusions The expression of TRPC6 is verified in normal human,mice and rats' kidneys,and in differentiated MPC5.These results will benefit for further exploring the relationship between TRPC6 and the proteinuria-related podocyte molecules.
