Race-related host and microbe transcriptomic signatures in triple-negative breast cancer.
Triple-negative breast cancer (TNBC) shows racial disparities, with higher incidence in women of African ancestry (AA) compared to European ancestry (EA). Meta-transcriptomic analysis of TNBC tumor tissues from AA (n = 17) and EA (n = 19) subjects revealed distinct microbial landscapes. Hierarchical clustering based on microbial transcripts separated samples into two groups predominantly defined by racial ancestry. Bacterial genera including Hafnia and Cedecea were more abundant in AA tumors, while Erwinia was higher in EA tumors. Cellular composition analysis by xCell revealed differences in immune cell populations, with AA tumors having higher Th1 cell abundance and EA tumors containing higher macrophage M2 cell abundance. Nonetheless, AA women with high M2 abundance experienced poorer disease-free survival (DFS) than EA women. Integrative analyses revealed that high expression of human SPDYE2B gene was associated with Hafnia abundance and decreased DFS, highlighting complex host-microbe interactions in TNBC patients.
期刊介绍：
npj Breast Cancer publishes original research articles, reviews, brief correspondence, meeting reports, editorial summaries and hypothesis generating observations which could be unexplained or preliminary findings from experiments, novel ideas, or the framing of new questions that need to be solved. Featured topics of the journal include imaging, immunotherapy, molecular classification of disease, mechanism-based therapies largely targeting signal transduction pathways, carcinogenesis including hereditary susceptibility and molecular epidemiology, survivorship issues including long-term toxicities of treatment and secondary neoplasm occurrence, the biophysics of cancer, mechanisms of metastasis and their perturbation, and studies of the tumor microenvironment.
