Zebrafish foxo3b suppresses hypoxia-induced gene expression.
A, foxo3b-null embryos (foxo3b−/−) exhibit higher vegf expression compared with their wild-type siblings (foxo3b
+/+) under normoxia and hypoxia. B, foxo3b-null embryos (foxo3b−/−) exhibit higher pou5f1 expression compared with their wild-type siblings (foxo3b
+/+) under normoxia and hypoxia. C, foxo3b-null embryos (foxo3b−/−) exhibit higher pai1 expression compared with their wild-type siblings (foxo3b
+/+) under normoxia and hypoxia. D, foxo3b-null embryos (foxo3b−/−) exhibit higher il11a expression compared with their wild-type siblings (foxo3b
+/+) under normoxia and hypoxia. E, foxo3b-null embryos (foxo3b−/−) exhibit higher vegf expression compared with their wild-type siblings (foxo3b
+/+) with or without DMOG (100 μm) treatment. F, foxo3b-null embryos (foxo3b−/−) exhibit higher pai1 expression compared with their wild-type siblings (foxo3b
+/+) with or without DMOG (100 μm) treatment.
