Lung Bcl-2 and TUNEL staining in neonatal p50^–/– mice after hyperoxia. (A) Immunohistochemical staining of Bcl-2 protein in neonatal p50^–/– mice exposed to 72 hours of air or hyperoxia. Note the unchanged Bcl-2 protein levels after hyperoxia. (B) TUNEL staining in neonatal WT and p50^–/– mice after 144 hours of hyperoxia. Note the visibly increased amount of TUNEL-positive staining in the lungs of neonatal p50^–/– mice as compared with the similarly exposed WT neonatal mice.
