TGF-β-activated lnc-ATB is involved in TGF-β signaling pathway, which interacts with miRNAs to govern TGF-β signaling pathway in various cells, including enhancement of TGFBR2 and SMAD2 by inhibiting the endogenous miR-425-5p in hepatic stellate cells53 and directly binding to miR-141-3p in gastric cancer cells54. The gene discussed is SMAD2; the disease is gastric cancer.
