[Retracted] Hypoxia Tumor Microenvironment Activates GLI2 through HIF-1α and TGF-β2 to Promote Chemotherapy Resistance of Colorectal Cancer

Figure 8

Cell viability was assessed with/without cancer-associated fibroblasts for 7 days in both normoxia or hypoxia environments when combined with chemotherapy treatments for seven days. In the western blot, cell viabilities of tumorsphere with three shGLI2-A, B, C were checked independently.
