Cell death executors, Caspase 6 and 7, were increased in gene expression in the ovarian cancer cell lines and only modest in LoVo-Li/4OHP, but in LoVo-Li/4OHP this was accompanied by an increased expression of the inhibitor of the apoptosis (IAP) gene, BIRC5 (Survivin), and decreased expression of BIRC4 (XIAP). Here, BIRC5 is linked to ovarian cancer.
