Because Ang displayed anti-apoptosis activity by Bcl family proteins and NF-κB pathway in pluripotential p19 mouse carcinoembryonic cells, we considered that the anti-apoptotic activity of Ang in astrocytoma may be accomplished possibly by regulating the expression of Bcl-xL and NF-κB pathway. Here, BCL2L1 is linked to astrocytoma (excluding glioblastoma).
