-254C>G SNP in the TRPC6 Gene Promoter Influences Its Expression via Interaction with the NF-κB Subunit RELA in Steroid-Resistant Nephrotic Syndrome Children.

ABSTRACT: This study is aimed at exploring the mechanism by which the -254C>G single nucleotide polymorphism (SNP) on the transient receptor potential cation channel 6 (TRPC6) gene promoter could increase its activation in steroid-resistant nephrotic syndrome children of China. Plasmids containing the TRPC6 promoter region (with the -254C or G allele) were constructed and then transfected into human embryonic kidney (HEK) 293T cells and human podocytes. Luciferase assays were used to test the promoter activity in both cell lines with or without tumor necrosis factor-α (TNF-α) treatment, and chromatin immunoprecipitation-polymerase chain reaction (ChIP-PCR) analysis was used to verify the transcription factor that could bind to this mutant sequence. Luciferase results indi
