This study, co-authored by Chandra Sekhar Pedamallu, uncovers significant race-associated host–microbe interactions in triple-negative breast cancer (TNBC). Through integrative meta-transcriptomic analysis of tumor tissues from African ancestry (AA) and European ancestry (EA) patients, the research reveals distinct microbial landscapes and immune profiles influencing disease-free survival.
The findings shed light on how specific bacterial genera and host genes together shape tumor progression. They emphasize the importance of considering microbial ecosystems as potential biomarkers for prognosis and therapeutic response. This work also underscores the need for race-informed approaches in cancer research, paving the way for more inclusive and precise treatment strategies.
Key findings include the association of Hafnia abundance and high SPDYE2B expression with poorer outcomes in AA patients, highlighting a complex interplay between tumor microbiome and host gene expression.
