Fig. 5: TKT confers radioresistance in HCC clinical samples.

A Representative immunohistochemistry images of the expressions of TKT in RT-Sensitive and RT-resistant HCC samples. Scale bar, 100 μm (Left) and 50 μm (Right). B Statistical analyses of the expression level of TKT from all HCC immunohistochemistry staining. *p < 0.05 of Student’s t test. C Schematic diagram summarizing TKT induces radioresistance via promoting DSB repair in HCC (Created by BioRender.com).
