doi: 10.3389/fphar.2021.700366
Figure Lengend Snippet: Knockdown of SGLT1 inhibited high-glucose–induced CF activation. CFs were transfected with SGLT1 siRNAs, and SGLT1 mRNA and protein levels were detected using RT‐qPCR (A) and western blotting, respectively (B) . CCK-8 assay was used to detect the proliferation of CFs under high-glucose condition with or without SGLT1 inhibition. (D, E) The representative images of the wound-healing assay were obtained at 0 and 24 h after knockdown of SGLT1, and the migrative ability of CFs was compared. (F–H) ELISA was used to detect the levels of collagen-synthesis–related markers, including TGF-β1, collagen I, and collagen III in the cell supernatant ( n = 6). (I) Western blotting analysis was performed to investigate the phosphorylation levels of p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase (ERK)1/2 in CFs under high-glucose condition with or without SGLT1 inhibition.
Article Snippet: The expression levels of collagen I, collagen III, and transforming growth factor-β1 (TGF-β1) in CFs and rat serum were detected using the rat collagen I Type I ELISA Kit (abx052369, Abbexa, United Kingdom), rat collagen type III ELISA Kit (abx573727, Abbexa), and TGF-β1 ELISA Kit (PT878, Beyotime, Jiangsu, China), respectively, following the instructions of the manufacturer.
