Overexpression of TGFBR1 lacking 3′ UTR may restore the effects of PL. a, b Cell growth curve and optical density value were obtained from the CCK-8 assay in cells treated with PL alone, PL combined with TGFBR1 lacking 3′ UTR, and blank control. c Cell migration ability was evaluated by the transwell assay in cells treated with PL alone, PL combined with TGFBR1 lacking 3′ UTR, and blank control. d, e Relative protein expression level of TGFBR1 was detected by western blotting after 48 h of PL treatment or TGFBR1 transfection
