This review highlights how the gut microbiome influences tumor microenvironment and stemness in PDAC, indicating a potential therapeutic avenue.
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive and malignant cancer of the pancreas characterized by various genetic mutations and metabolic dysregulations. Stem cells play a critical role in the initiation, progression, and resistance of PDAC due to their plasticity, self-renewal capabilities, and ability to drive tumorigenesis. The gut microbiome, a diverse ecosystem of microorganisms, has a profound influence on systemic health, including the development of cancer. Recent studies have highlighted that the microbiome composition within the tumor can modulate stem cell behavior by shaping the tumor microenvironment (TME), enhancing cellular plasticity, and promoting the stemness properties of PDAC. In this review, we explore the potential crosstalk between the gut microbiome and PDAC stem cells, focusing on how microbiome-derived signals impact stem cell maintenance, inflammation, metastasis, TME modulation, and metabolic reprogramming.
