Abstract
BACKGROUND: Few studies have explored the expression profile of RPL3 in breast cancer (BRCA). Our research provided an in-depth analysis of RPL3 expression patterns in BRCA, highlighting its significance for therapy prediction and prognosis. METHODS: RPL3 was notably elevated in malignant cells, and its expression level was closely associated with tumor size and overall survival outcomes. Our study also identified RPL3-related terms and pathways and revealed a strong correlation between RPL3 expression and breast carcinoma immunity, demonstrating inconsistent expression levels in various immune cell lines. In addition, we examined the relationship between RPL3 expression and tumor mutational burden (TMB) in BRCA. To assess the clinical implications of BRCA chemotherapy, we investigated the correlation between RPL3 expression levels and drug sensitivity. RESULTS: Our findings suggest that RPL3 plays a critical role in the BRCA process and is associated with immune infiltration, indicating its potential as a novel immunotherapy target in BRCA treatment. CONCLUSIONS: In summary, our research underscores the importance of RPL3 expression levels in tumorigenesis and its potential for guiding BRCA immunotherapy.
