BCL2L2 and perinatal asphyxia: In relation to BCL2L2, BNIP3 (FC = 1.17, p = 0.04) encodes BCL2 interacting protein 3, which is increased in hypoxic-ischemic-encephalopathy [18] and physiological ageing [31], and has been shown to increase in association with cellular senescence especially in cells over-expressing p21 and p16 [16].
