Unravelling novel microbial players in the breast tissue of TNBC patients: a meta-analytic perspective.

ABSTRACT: Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer (BC), accounting for nearly 40% of BC-related deaths. Emerging evidence suggests that the breast tissue microbiome harbors distinct microbial communities; however, the microbiome specific to TNBC remains largely unexplored. This study presents the first comprehensive meta-analysis of the TNBC tissue microbiome, consolidating 16S rRNA amplicon sequencing data from 200 BC samples across four independent cohorts. Our analysis highlights the enrichment of Azospirillum genus as well as butyrate-producing species, namely Gemmiger formicilis and Anaerobutyricum soehngenii, potentially influencing TNBC aggressiveness and clinical outcomes. Additionally, our functional analyses reveal the involvement of the TNBC mi
