BCL2L1 and osteosarcoma: A similar anti-cancer effect mediated by the inhibition of STAT5 phosphorylation was observed in Rat prolactinoma MMQ cells through inhibition of the STAT5/Bcl-xL and STAT5/cyclin D1 signaling pathways, in peripheral T-lymphoma through induction of the TRAIL/DR4-dependent apoptosis [67], and in osteosarcoma cells through inhibition of the proliferation of osteosarcoma stem cells [68].
