Association of Dll4 Levels and VEGFR-1, VEGFR-2 in Mice Model of Oxygen-Induced Retinopathy

Liu Wangkai , Su Yihua , Zhuang Siqi , Li Xiaoyu , Li Yijuan

Background: Notch1 – Delta-like ligand 4 (Dll4) signaling pathway has a biological effect of negative feedback regulation to VEGF in retinal vascular development process. There are few studies on the inhibition of Notch1-Dll4 signaling pathway in ROP and the regulatory pathway of VEGF.Objective and hypotheses: 67-day-old mice were divided into oxygen-induced retinopathy group and control group. We took ten mice from each group at postnatal day 7 (p7...

The genetic disorder Prader-Willi syndrome (PWS) is mainly caused by the loss of multiple paternally expressed genes in chromosome 15q11-q13 (the PWS region). Early diagnosis of PWS is essential for timely treatment, leading to effectively easing some clinical symptoms. Molecular approaches for PWS diagnosis at the DNA level are available, but the diagnosis of PWS at the RNA level has been limited. Here, we show that a cluster of paternally transcribed snoRNA-ended long noncod...
