Figure S1 from Neoadjuvant Chemotherapy Shifts Breast Tumor Microbiota Populations to Regulate Drug Responsiveness and the Development of Metastasis

Obesity influences breast tumor microbiota populations. Breast tumor 16S sequencing results were stratified based upon patient body mass index (BMI). Tumor bacterial populations from non-obese patients with a BMI of 20-27 (n=9) were compared with bacterial populations from obese patients with a BMI of 31-48 (n=8). A. Relative abundance of bacterial genera in different tumor samples is visualized by bar plots. Each bar represents a single tumor and each colored box a bacterial taxon. The height of a color box represents the relative abundance of that organism within the sample. ''Other'' represents lower abundance taxa. B. Phylum level distribution in tumors from obese and non-obese patients. Primary breast tumors from obese patients have decreased proportional abundance of Comamonadaceae (C) and Ruminococcaceae (D) family level taxa. E. Obese patients' breast tumors display elevated abundance of Enterobacteriaceae_unclassified. *p
