Fig. 6: Combination of radiotherapy and immunotherapy impacted the expression levels ferroptosis-related proteins in Hepa1-6 cells through targeting Alkbh5/Hspb1 axis.

Hepa1-6 cells were treated with RT+anti-PD-1 or/and Alkbh5-OE. A RT-qPCR assay was performed to measure Alkbh5, Hspb1, Tfr1, Pcbp1, Gpx4, and Acsl4 levels in Hepa1-6 cells. B Western blot assay was performed to measure Alkbh5, Hspb1, Tfr1, Pcbp1, Gpx4, Slc7a11 and Acsl4 levels in Hepa1-6 cells. *P < 0.05, **P < 0.01, ***P < 0.001.
