Fig. 7From: Epithelial and interstitial Notch1 activity contributes to the myofibroblastic phenotype and fibrosisNotch1 activity mediates myofibroblastic phenotype dependent on TGF-β1 in vitro. a The mRNA expression levels of TGF-β1R, Col3α1 and α-SMA in NRK52E and NRK-49F cells treated with TGF-β1 with or without pcDNA3.1-NICD plasmid or NICD siRNA. b The protein expression levels of TGF-β1R, α-SMA and collagen III in NRK52E and NRK-49F cells treated with TGF-β1 with or without pcDNA3.1-NICD plasmid or NICD siRNA. c The mRNA expression levels of Smad2 and Smad3 in NRK52E and NRK-49F cells treated with TGF-β1 with or without pcDNA3.1-NICD plasmid or NICD siRNA. d The protein expression and phosphorylation levels of Smad2 and Smad3 in NRK52E and NRK-49F cells treated with TGF-β1 with or without pcDNA3.1-NICD plasmid or NICD siRNA. All data are presented as means ± SDs.
