TGFB1 and asthma: Recently, studies on the pharmacological effect of ASV have demonstrated its antioxidant, anti‐inflammatory, anti‐diabetes, anti‐hypertensive, anti‐asthma, and anti‐fibrotic properties.10 ASV was found to alleviate the progression of kidney fibrosis via inhibition of MAPK pathway and TGF‐β/Smad signalling pathway.11, 12 Besides, ASV could protect against TGF‐β1‐induced EMT by inhibiting in peritoneal mesothelial cells by promoting smad 7 expression.13 These all indicated the great potential of the anti‐fibrosis and anti‐EMT activity of ASV.
