This article aims to study the expression of the Notch signaling pathway in the retina of RCS rats. Real-time quantitative PCR (qPCR) was used to analyze the expression of Notch1, Notch2, Notch3, Hes1, Hes5, Dll1, and Dll3 in tissue samples of RCS rat retina, and immunohistochemical techniques were used to detect the immunoreactivity of Notch1, Hes1, and Dll1 in the retina. The results showed that Notch1, Notch2, Notch3, Hes1, Hes5, Dll1, and Dll3 genes were expressed in the retina, and Notch1, Hes1, and Dll1 had higher immunoreactivity in the retina. These results reveal the existence of the Notch signaling pathway in the retina of RCS rats, and further research on its role in retina development and disease is promising in the future.【Key Words】 Notch signaling pathway；RCS rats；retina；expression；qPCR；immunohistochemistry
