Tumor microbiome contributes to an aggressive phenotype in the basal-like subtype of pancreatic cancer

Abstract

Guo, Zhang, Guo et al. investigate microbiome alterations in different molecular subtypes of PDAC and report that distinct signatures exist in basal-like tumours, characterized by an increase in certain bacteria, such as Acinetobacter, Pseudomonas and Sphingopyxis. The authors associate increases in these bacteria with increased inflammation and carcinogenic potential, as suggested by pathway analyses.
