In recent years, with the development of advanced biotechnology, the research on eye diseases has become more profound. In this study, we investigated the effects of supplementing Jingyi Visual Patch on the signal transduction pathway of apoptosis in photoreceptor cells induced by N-methyl-N-nitrosourea (MNU) in rats. The results showed that the supplement of Jingyi Visual Patch can suppress photoreceptor cell apoptosis and alleviate the severity of the lesions. Introduction: Eye diseases are common clinical conditions, and the apoptosis of photoreceptor cells is recognized as an important pathogenic mechanism. Photoreceptor cell apoptosis is a programmed cell death that plays a crucial role in eye diseases such as retinitis pigmentosa and diabetic retinopathy. However, our understanding of the molecular mechanisms underlying photoreceptor cell apoptosis remains limited. Materials and Methods: Male SD rats aged 3 months were used in this study and divided into experimental and control groups. The experimental group received MNU treatment to induce photoreceptor cell apoptosis, while the control group was injected with saline. Additionally, in the experimental group, Jingyi Visual Patch was supplemented to investigate its inhibitory effect on photoreceptor cell apoptosis. After the experiments, we examined the apoptosis of photoreceptor cells and compared the differences between the experimental and control groups. Results: The results showed that photoreceptor cells in the MNU-treated rats exhibited significant apoptosis, while the supplementation of Jingyi Visual Patch significantly reduced photoreceptor cell apoptosis. Further experiments revealed that Jingyi Visual Patch can modulate apoptosis-related signaling pathways, such as the Bcl-2 family, cysteine proteinase family, and caspase family. Discussion: The results of this study suggest that Jingyi Visual Patch can suppress photoreceptor cell apoptosis by regulating apoptosis-related signaling pathways. The Bcl-2 family proteins play a crucial protective role in cell apoptosis, while caspase family proteins are the main executors of apoptosis. The cysteine proteinase family can modulate the apoptotic program of cells. Moreover, Jingyi Visual Patch may also inhibit photoreceptor cell apoptosis through other unknown pathways, which requires further investigation. Conclusion: This study demonstrates that supplementing Jingyi Visual Patch can suppress photoreceptor cell apoptosis by regulating the signal transduction pathway in rats induced by MNU. This finding has important implications for the treatment of eye diseases, and further research can explore the pharmacological effects and clinical applications of Jingyi Visual Patch.
