SOX9 and cervical cancer: Differing from miR-361, SOX9 mRNA and protein expression was significantly upregulated in DDP-resistant Caski/DDP and HeLa/DDP cells compared with that in original Caski and HeLa cells (Figures 3A, B), and upregulated in DDP-resistant cervical cancer tissues in comparison with non-resistant samples (Figure 3C).
