Celf1 promotes dmrt2a mRNA decay in vivo. (A) Effect of Celf1 on dmrt2a expression in zebrafish embryos. Total RNAs extracted from embryos injected with control-MO, celf1-MOs, dmrt2a-TP-MO, mRFP mRNA, celf1 mRNA or celf1Δlinker mRNA at 12-14 hpf were subjected to qPCR for dmrt2a and β-actin. The samples were normalized to β-actin as a reference. (B) dmrt2a mRNA is stabilized in embryos injected with celf1-MOs or dmrt2a-TP-MO. Decay rate of dmrt2a mRNA was assessed in embryos injected with control-MO, celf1-MOs or dmrt2a-TP-MO by qPCR following transcription inhibition using Actinomycin D. The samples were normalized to β-actin as a reference. control-MO: t1/2=317±11 minutes; celf1-MOs: t1/2=835±3 minutes; dmrt2a-TP-MO: t1/2=1487±4 minutes. Error bars represent s.d. |
