“…MC-LR exposure also induced TUNEL-positive testicular cells in rats following chronic, sub-chronic and acute exposure [46,64,65]. MC-LR-induced apoptosis/necrosis of rat Sertoli cells [71][72][73], spermatogonia [68], Chinese hamster ovary (CHO) cells [76,77,80,81], and ovary cells of zebrafish [85] were also observed. Apoptosis of HeLa cells was also observed following exposure to MC-RR [82].…”
