Fig. 5From: Antiproliferative activity of marine stingray Dasyatis sephen venom on human cervical carcinoma cell lineEffect of D. sephen venom on reduced GSH levels in HeLa cells. Treated cells were incubated for 24 h at 37 °C and then reduced GSH levels were measured in cell lysate. Values were given as mean ± SD of six experiments in each group. Values not sharing the same letter differ significantly (p < 0.05) from control (DMRT)Back to article page
