Western blot analysis showing effects of xyloketal B on the expression of apoptosis-related proteins in neonatal HI brain injury. Proteins were extracted from ipsilateral brain of mice. (A). Representative western blot showing the level of cleaved caspase-3 protein 1 day after HI insult; (B) Densitometric analysis of cleaved caspase-3 bands of sham, vehicle-treated HI- and xyloketal B-treated HI brains. Xyloketal B pretreatment decreased the expression of cleaved caspase-3 (cleaved casp-3) proteins 24 h after HI in comparison to the vehicle-treated HI group; (C) Representative western blot showing the level of Bcl-2 and Bax protein 1 day after HI insult; (D) Densitometric analysis of Bcl-2 bands of sham, vehicle-treated HI and xyloketal B treated HI brains. Xyloketal B pretreatment increased the expression of Bcl-2 proteins 24 h after HI in comparison to the vehicle-treated HI group; (E) Densitometric analysis of Bax bands of sham, vehicle-treated HI- and xyloketal B-treated HI brains. Xyloketal B pretreatment decreased the expression of Bax protein 24 h after HI in comparison to the vehicle-treated HI group; (F) Densitometric analysis of the ratio of Bcl-2-to-Bax bands of sham, vehicle-treated HI and xyloketal B treated HI brains. Xyloketal B pretreatment increased the ratio of Bcl-2-to-Bax in comparison to the vehicle-treated HI group. *: p < 0.05, n = 3. Sham: Sham-surgery group; HI: Hypoxic-ischemic injury group; Xyl B + HI: hypoxic-ischemic injury plus pretreatment with xyloketal B group.
