Mechanosensitive expression of heg1 mRNA and stabilization of Krit1 protein levels by heg1. (A) RT-qPCR quantifications of heg1 and krit1 mRNA levels at 54 hpf in morphant embryos lacking blood-flow [troponin T type 2a (tnnt2a)], or Krüppel like factors 2a and 2b (klf2a/b) compared with wild-type expression levels. (B) RT-qPCR quantification showing that heat-shock-induced overexpression of klf2a causes significant upregulation of heg1 but not of krit1 expression at 54 hpf. (C–E) Morpholino-mediated knockdown of Heg1 significantly reduces endocardial EGFP-Krit1 protein levels of 30 hpf Tg(fli:GAL4FF)ubs3; Tg(UAS:EGFP-Krit1)pbb21 embryos. Scale bars are 50 µm. Mean values ± SEM of three (tnnt2a MO, hs:klf2a, heg1 MO) or four (klf2a/b MO) individual experiments are shown. Ratio paired (A, B) or unpaired (E) t-test was used to compare each condition with controls (ns: not significant, *p<0.05, ***p<0.001). |
