Figure 5. SOX9 regulates OPN expression in HLF and PLC/PRF/5 cells.

Figure 5

(A) RT-PCR analysis of SOX9/OPN in HCC cell lines (left) and qRT-PCR analysis of OPN in SOX9+/SOX9 HLF and PLC/PRF/5 cells (right, Student’s t-test, *P < 0.05). Data are shown as the mean ± SD. (B) Western blot analysis of SOX9 and OPN in SOX9+/SOX9 cells with SOX9-gain/loss of function experiments revealed that SOX9 induced OPN expression. (C) Western blotting with OPN-gain/loss of function experiments showed that OPN did not regulate SOX9 expression. (D–F) OPN did not affect the Wnt/beta-catenin activity including nuclear-localization of beta-catenin, cell proliferation, and the expression of cyclin D1 (D,F Student’s t-test, not significant, E; repeated-measures ANOVA, not significant). Scale bar represents 100 μm.
