Our hypothesis was also supported by a previous study showing ASV could up‐regulate Smad7 in the TGF‐β1/Smad signaling pathway to inhibit the progress of EMT in peritoneal mesothelial cells.13 Importantly, Li et al17 identified that ASV inhibited the increased α‐SMA in the BLM‐induced fibrosis. The gene discussed is SMAD7; the disease is Bloom syndrome.
