Additional file 2 of Vitamin A bio-modulates apoptosis via the mitochondrial pathway after hypoxic-ischemic brain damage

Figure S2. (A) The experimental flow chart. (B) The special feed formulations for the vitamin A deficiency (VAD) and normal (VAN) groups. (C) The vitamin A level of the VAD, VAN, VA supplement (VAS), and control groups during the course of the study. The VA level of VAN rats (N = 50) was significantly higher than that of VAD rats (N = 50) at every stage after HIBD (**P ≤ 0.01, *P ≤ 0.05, SNK). The VA level of VAS rats (N = 50) was significantly higher than that of VAD rats (N = 50) on post-HIBD days 7–40(P7–P40) (**P ≤ 0.01, *P ≤ 0.05, SNK). The VA levels of all the groups had an increasing trend from P1 to P40. The data are expressed as the means ± SEM. (TIFF 3295 kb)
