CD99 is a potential diagnostic and immunological biomarker in pan-cancer

Abstract Background: As a cell adhesion factor, cluster of differentiation 99 (CD99) mainly plays a role in regulating cell differentiation. In cancer research, CD99 primarily focuses on sarcoma. Recent studies have revealed that CD99 plays a critical role in the initiation and progression of several cancers. However, a comprehensive pan-cancer analysis of CD99 has not been performed. Methods: In this study, we utilized advanced bioinformatics techniques to conduct an in-depth investigation of CD99 expression across diverse tumors, its prognostic and
