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

Figure 1

Cancer-associated fibroblasts (CAFs) in hypoxic environment induce chemoresistance in a GLI2-dependent manner. The cell viability was checked where the cells were both left treated and untreated with CAF conditional medium which was followed by administration with chemotherapeutic reagents for other five days.
