Fig. 4. HBx increases the m6A level of cFAM210A by promoting the expression of RBM15.

a, b qRT‒PCR (a) and Western blot (b) results showing the mRNA and protein levels of m6A regulators in HBx-oe and NC cells. c Dual-luciferase assay results indicating the activity of the RBM15 gene promoter in HBx-oe and NC cells. d Western blot results showing the knockdown efficiency of si-RBM15 in HCC cells. e, f MeRIP-qPCR (e) and qRT‒PCR (f) results showing the m6A level and expression of cFAM210A in si-RBM15 and si-NC cells. g Western blot results showing the knockdown efficiency of si-RBM15 and overexpression efficiency of the HBx-oe vector in HepG2 cells. h, i MeRIP-qPCR (h) and qRT‒PCR (i) results in HepG2 cells showing that the effects of si-RBM15 were abolished by overexpressing HBx. For (a), (f) and (i), ACTB was used as an endogenous control. For (a), (c), (e), (f), (h) and (i), Student’s t test was used. NC negative control, HBx-oe HBx-overexpressing, ns not significant. *P < 0.05; **P < 0.01; ***P < 0.001.
