Core Tip

Core Tip: In this study, we performed a systematic analysis of prognostic splicing events in stomach adenocarcinoma (STAD), constructed an elevated Alternative splicing (AS)-signature prognostic model, and explored the association between AS and cancer immunity. The final overall survival-related AS events, differentially expressed immune-related genes, and the enriched pathways may play an important role in tumorigenesis in STAD; they deserve further study in clinical applications as diagnostic biomarkers and therapeutic targets.
