HB-EGF and Ascl1a Regulate Notch-Signaling Component Genes in the Injured Retina (A) Real-time PCR shows injury-dependent induction of Notch-signaling components. (B) RT-PCR shows that HB-EGF activates Notch-signaling component genes in the uninjured retina. (C) RT-PCR shows that MO-mediated HB-EGF_a knockdown suppresses injury-dependent induction of Notch-signaling component genes. (D) Real-time PCR quantification of (C). ^*p < 0.01. (E) RT-PCR shows that Ascl1a knockdown suppresses injury-dependent induction of Notch-signaling component genes. (F) Real-time PCR quantification of (E). ^*p < 0.01. (G) Ascl1a knockdown suppresses HB-EGF-dependent induction of notch1 and her4 mRNAs. Arrows identify notch1 and her4 mRNA expression in control MO-treated cells. Scale bar, 50 μm. Error bars represent SD. ONL, outer nuclear layer; INL, inner nuclear layer; GCL, ganglion cell layer. See also Figures S4 and S5.
