Project description:We found several genes differentially regulated by TRPC6, and in this study focused on ESRP1 (Epithelial Splicing Regulatory Protein 1)
Project description:Inhibition of transient receptor potential canonical 6 channels (TRPC6) alleviates tubular injury and renal fibrosis induced by unilateral ureteral obstruction (UUO).However, the exact renoprotective mechanisms are unknown. In this study, we utilized single-cell RNA sequencing (scRNA-Seq) to define the cellular and transcriptional landscape associated with renoprotection through in vivo TRPC6 inhibition, specifically using SH045 (larixyl N-methylcarbamate), in the UUO model.

Project description:To investigate the mechanism of TRPC1 or TRPC6 on the regulation of endotoxemic cardiac dysfunction, we established Trpc1-/- and Trpc6-/- mice. LPS-challenged endotoxemic mouse model was built, and the gene expression profile was analyzed using data obtained from RNA-seq of WT, LPS-challenged WT, LPS-challenged Trpc1-/-, and LPS-challenged Trpc6-/- mice hearts.
Project description:The aim of this project was to detect phosphorylation on the human calcium Channel TRPC6. TRPC6 is mutated in genetic diseases of the podocyte, a postmitotic cell at the epithelial filtration barrier
Project description:As TRPC6 channel induces CREB-mediated trancription, Dental pulp cells from TRPC6-mut patient and from 6 controls were analyzed in order to verify if the disruption of TRPC6 leads to transcriptional changes.
Project description:Baroreflex control of cardiac contraction (positive inotropy) through sympathetic nerve activation is important to maintain cardiocirculatory homeostasis. Transient receptor potential canonical subfamily (TRPC) channels are responsible for alfa1-adrenoceptor (alfa1AR)-stimulated cation entry and their upregulation is reportedly associated with pathological cardiac remodeling, but whether TRPC channels participate in physiological pump functions remains unclear. Here, we demonstrate that TRPC6-specific Zn2+ influx potentiates alfa-adrenoceptor (alfaAR)-stimulated positive inotropy in rodent cardiomyocytes. Deletion of the trpc6 gene impairs sympathetic nerve-activated positive inotropy, but not chronotropy in mice. TRPC6-mediated Zn2+ influx boosts alfa1AR-stimulatedalfaAR/Gs-dependent signaling in rat cardiomyocytes by inhibiting alfa-arrestin-mediated alfaAR internalization. Replacing two TRPC6-specific amino acids in the pore region with those of TRPC3 diminishes the alfa1AR-stimulated Zn2+ influx and positive inotropic response. Pharmacological enhancement of TRPC6-mediated Zn2+ influx prevents the progression of heart failure in dilated cardiomyopathy mice. Our data provide evidence that TRPC6-mediated Zn2+ influx with α1AR stimulation enhances baroreflex-induced positive inotropy, which may be a new therapeutic strategy for chronic heart failure.
Project description:As TRPC6 channel induces CREB-mediated trancription, Dental pulp cells from TRPC6-mut patient and from 6 controls were analyzed in order to verify if the disruption of TRPC6 leads to transcriptional changes. Cells were grown until reach 80-90% of confluency in DMEM/F12 media supplemented with 15% fetal bovine serum (Hyclone, TX), 1% penicillin/streptomycin, and 1% non-essential amino acids and maintained under standard conditions (37°C, 5% CO2). RNAs samples were extracted from cells in passage 5 to 7.
