doi: 10.3390/cancers17081286
Figure Lengend Snippet: The viability of parental PCa cells and the established radioresistant PCa cells 24 h after 5-ALA administration (( a ) PC-3 and PC-3-R; ( b ) DU 145 and DU 145-R). The survival curves of the relative survival fractions in the parental PCa cells and the established radioresistant PCa cells after IR (2–8 Gy single dose) alone or a combination of 1 mM 5-ALA and IR (( c ) PC-3 and PC-3-R; ( d ) DU 145 and DU 145-R). ( e , f ) HIF-1a and HIF-2a expression in the parental and radioresistant PCa cells was measured via Western blot analysis. 5-ALA: 5-aminolevurinic acid. D 50% : radiation dose required to achieve a 50% survival rate. HIF: hypoxia-inducible factor. IC 50 : half-maximal inhibitory concentration. IR: irradiation. PCa: prostate cancer. * p < 0.05, *** p < 0.001. Original western blots are presented in File S1.
