Bcl-w is an anti-apoptotic protein that promotes cell survival, while Beclin1 is a key regulator of autophagy, which is a cellular process that plays a critical role in the maintenance of cellular homeostasis and the elimination of damaged or unwanted cellular components. Both of these proteins have been implicated in the development and progression of various types of cancer. However, their expression and significance in non-neoplastic conditions of the vulvar epithelium have not been fully investigated.Objective:The aim of this study is to investigate the expression of Bcl-w and Beclin1 in non-neoplastic conditions of the vulvar epithelium and to evaluate their potential significance in the pathogenesis of these conditions.Methods:This study will be conducted as a retrospective analysis of vulvar biopsies obtained from patients with non-neoplastic conditions of the vulvar epithelium, such as vulvar lichen sclerosus and vulvar intraepithelial neoplasia. Immunohistochemical staining will be performed to detect the expression of Bcl-w and Beclin1 in the biopsy samples. The staining intensity and distribution of these proteins will be assessed and compared with the corresponding clinical and pathological data.Expected outcomes:Based on previous studies, we expect to find that Bcl-w is upregulated and Beclin1 is downregulated in non-neoplastic conditions of the vulvar epithelium, which may contribute to the dysregulation of cell survival and autophagy in these conditions. The results of this study may provide new insights into the pathogenesis of non-neoplastic vulvar conditions and 精品文档---下载后可任意编辑may help to identify new targets for their treatment and management.
