نبذة مختصرة : Supplementary Material 1: Fig. S1 Research flow chart. This research began by comparing proteins in early-stage endometrial cancer (EC) patients with varying outcomes using proteomics. LASSO regression was used to identify 13 key proteins. After a thorough literature review and protein function prediction and classification, we identified 5 crucial proteins involved in the p53 signaling pathway. The expression of these proteins was confirmed by single-cell transcriptome (scRNA-seq). The interactions between cellular subpopulations and the intercellular communication between the TRAP1low/CAMSAP3low cluster and the tumor microenvironment (TME) have received particular attention. Finally, the prognostic proteins were validated by immunohistochemistry (IHC) and data from the TCGA database. Based on this, a TP53-based model to predict outcomes for early-stage EC was created and optimized. This figure was created with BioRender.com ...
