Popis: | We combined pyropheophorbide-a methyl ester, photodynamic therapy (MPPa-PDT), 670 ± 10 nm, 4 mW/cm2, with herpes simplex virus type 1 thymidine kinase/ganciclovir (HSV1-TK/GCV) to improve the therapeutic effect. We built HSV1-TK expression vector GV230-TK and we observed a bright green fluorescence under fluorescence microscope. It indicated the recombinant plasmid was transfected into PC-3M prostate cancer cells successfully. As the abundant glucose-regulated protein 78 (GRP78) promoter in PC-3M cells can cause active expression of HSV1-TK, cell protein was collected for western blot to determine the expression of HSV1-TK. In CCK-8 assay (n = 6), the cell survival rate of combined treatment group was about 10%, less than that of pure MPPa-PDT group (23%) and pure HSV1-TK/GCV group (35%) (t test, P |
