Photodynamic therapy resistant human colon carcinoma HT29 cells show cross-resistance to UVA but not UVC light.

Photochemistry and photobiology - 1 Jan 2000

Zacal Natalie, Rainbow Andrew J

Abstract excerpt

The isolation of photodynamic therapy (PDT)-resistant HT29 human colon adenocarcinoma cells has been reported previously. These PDT-resistant variants show increased expression of the Hsp27 and BNip3 proteins and a decreased expression of mutant p53 protein compared with parental HT29 cells. Because mutant p53 and increased expression of Hsp27 have been associated with resistance to various chemotherapeutic...
