In pancreatic ductal adenocarcinoma tumors from the PancFit trial, higher exercise is linked to fewer αSMA+ cells and fewer IL6-expressing iCAFs, alongside lower tumor IL6 expression.
- Why it matters: Exercise can beneficially alter the tumor microenvironment, but the clinical mechanisms and why responses vary across patients remain unclear.
- What they did: Tumor analyses in PancFit were paired with a murine PDAC model to test exercise effects on stromal composition, including microbial influences; cholic acid was measured as a candidate mediator.
- The result: Exercise increased cholic acid and is associated with a microbially influenced reduction in αSMA+ cells and IL6+ iCAFs, implying microbial metabolites may help drive exercise-linked stromal remodeling.
