Fig. 6From: The marine triterpene glycoside frondoside A induces p53-independent apoptosis and inhibits autophagy in urothelial carcinoma cellsEffect of FrA in combination with cisplatin and gemcitabine. Cells were cotreated with different concentrations of the single substances or their combination for 48 h at the constant molar ratios C(FrA) : C(Cis) = 1 : 4 (a) and C(FrA) : C(Gem) = 1 : 0.25 (b). The combinational index (CI) values were calculated with CompuSyn software. The viability was examined using a trypan blue-based viability assayBack to article page
