Fig. 7. Knock-out of p62 expression decreases a sensitivity to radiation and senescence induction in HN9-S clones.

Fig. 7

A, B HN9-S cells were totally ablated of endogenous p62 using the CRISPR/Cas9 system (p62 KO), after which a reversal construct of wild type p62 was transiently transfected to p62 KO cells (p62 recons). Clonogenic survival (A) and percentage of cells positive for SA-β-gal staining (B) in HN9-S and p62 gene-edited HN9-S cells after irradiation (n = 3). Results are presented as means ± standard error of the mean (SEM). ***p < 0.005. C Overview of the different epigenetic regulation of p62 expression and the survival responses against irradiation in subclones, HN9-R and HN9-S, within a radio-resistant head and neck cancer tumor.
