Ehbp1l1^−/− mice exhibit lethal anemia. (H) WCEs from Ehbp1l1^−/− mouse embryonic fibroblasts transfected with pcDNA3 encoding EHBP1L1 isoform B, C, E, or X5 and WCEs from E14.5 mouse FL were subjected to western blotting. ∗∗∗P < .001, ∗∗∗∗P < .0001 (unpaired t test with Welch’s correction in panel D; 1-way analysis of variance [ANOVA] in panel F).
