Figure Lengend Snippet: circNRIP1 activates CAFs by binding to TRMT6. A Graphical representation of the molecular docking between circNRIP1 and the TRMT6 protein using HDock. B , C Western blot was conducted to validate the circNRIP1 pull-down products in fibroblasts. D The expressions of TRMT6 were determined by western blot and real-time PCR. E , F Transwell assays detected the migration of CAFs. G ELISA assays detected the secretion of IL-1β and TGF-β in CAFs. H Western blot detected the expression of α-SMA and COL1A1 in CAFs. (NC: fibroblasts without treatment, shcircNRIP1: fibroblasts co-cultured with shcircNRIP1 exosomes, TRMT6-OE: TRMT6-overexpressing fibroblasts, shcircNRIP1 + TRMT6-OE: TRMT6-overexpressing fibroblasts co-cultured with shcircNRIP1 exosomes.) Data represent mean ± S.D. of three independent experiments. * P < 0.05, ** P < 0.01, **** P < 0.0001
