Differential expression of ABO in normal and tumor tissues: Implications for cancer biology and prognosis

Abstract Objectives: ABO, which is primarily recognized for determining blood types, shows variable expression patterns in different tissues and cancer types. This study investigated the relationship between gene expression and cancer, and assessed its potential impact on patient survival. Methods: Utilizing the GEPIA database, we analyzed ABO expression in normal and tumor tissues across various cancer types using online in silico tools for comprehensive evaluation. Results: The analysis revealed significant disparities in ABO expression among different tissue types. Notably, ovarian
