In vitro | METHODS: Human dermal fibroblasts were treated with (E)-SIS3 (10 μM) for 24 hours, and the expression levels of target proteins were detected by Western Blot and Immunoprecipitation. RESULTS: (E)-SIS3 attenuated TGF-beta1-induced Smad3 phosphorylation and Smad3 / Smad4 interaction. [1] METHODS: Human dermal fibroblasts were treated with (E)-SIS3 (0.1-50 μM) for 30 minutes, and the expression levels of target proteins were detected by Western Blot. RESULTS: (E)-SIS3 significantly inhibited the expression of FN and α-SMA, but not the expression of Sphk2 induced by TGF-β1. [2] METHODS: Human dermal fibroblasts were treated with (E)-SIS3 (10 μM) for 24 hours, and the expression levels of target proteins were detected by Western Blot. RESULTS: (E)-SIS3 significantly decreased the expression of α-SMA and Palladin in primary human dermal fibroblasts. [3] |
In vivo | SIS3 inhibits Smad3 activation in streptozotocin(STZ)-induced diabetic nephropathy in Tie2-Cre;Loxp-EGFP mice. It also reduces AGE-induced EndoMT and decreases EndoMT in STZ-induced diabetic nephropathy in Tie2-Cre;Loxp-EGFP mice. SIS3 significantly reduces collagen IV and fibronectin expression in the glomeruli and tubulointerstitium of STZ-injected Tie2-Cre;Loxp-EGFP mice, suggesting that SIS3 retards the early development of STZ-induced diabetic glomerulosclerosis and tubulointerstitial fibrosis. However, SIS3 administration does not reduce proteinuria[2]. |
Cell Research | Normal human dermal fibroblasts are plated at a density of 105 cells/well in six-well culture plates and grown until subconfluence in MEM containing 10% FCS. Cells are quiesced by 24-h incubation in serum-free MEM, followed by incubation in serum-free medium in the presence or absence of SIS3 before the collection of cells for 72 h. Then, the cells are detached from the wells by trypsin treatment and counted using a Coulter counter.(Only for Reference) |
