BIRC5 and cancer: Mashanov et al. [72] reported that two pro-cancer genes, survivin and mortalin, were overexpressed only during regeneration in the sea cucumber, and Mashanov et al. [80] found that Wnt9, TCTP, and Bmp1/Tll, which have been previously known to be implicated in embryogenesis and cancer, were up-regulated in visceral regeneration in the sea cucumber H. glaberrima.
