ARL4C regulates β-catenin expression through the JAK2/STAT5A signal pathway. (AD) The expression of p-JAK2 in HCC827-ARL4C-SH, HCC827-Vector, and HCC827 (control) cells (A) and in HCC827/ER-ARL4C-OE, HCC827/ER-Vector, and HCC827/ER (control) cells (B) detected by Western blot. STAT5 protein expression in HCC827-ARL4C-SH, HCC827-Vector cells (C) and in HCC827/ER-ARL4C-OE, HCC827/ER-Vector cells (D) also detected by Western blot. (E) The enrichment of the β-catenin (CTNNB1) promoter in immunoprecipitated (IP) STAT5 and the input of STAT5 in HCC827/ER-ARL4C-OE, HCC827/ER-Vector, HCC827-ARL4C-SH, and HCC827-Vector and followed by Western blot. Unrelavant IgG was used as a negative control staining. (F,G) Luciferase activity in HEK293T cells (F) and HCC827 cells (G) co-transfected with pGL3-CTNNB1-Luc or mut-pGL3-CTNNB1-Luc and HBLV-ARL4C-SH3 by the Dual-Luciferase Reporter Assay System, ***P < 0.001.
