p53 and Caspase-3 assay of embryonic cell under normoxia and hypoxia.

<p>(A). p<i>53</i>: p<i>53</i> expression was highest (<i>p</i><0.05) during 7 hpf, Beyond 24 h, p53 did not show any expression. p53 expression was not detected in normoxic embryos,. (B). Caspase 3: Caspase-3 showed significantly higher (p<0.05) expression in early stages during 2 hpf (cleavage stage) in hypoxia exposed embryos compared to control (normoxia). Different superscripts indicate significant differences (<i>p</i><0.05) amongst hypoxic and normoxic groups at different times. Values are expressed as mean ± SEM (n = 10).
