abstract = {Exercise potentially inhibits tumor growth. It remains
unclear which processes mediate these effects. Alterations
of cytokine concentration in serum can influence cancer cell
growth and may cause cell growth inhibition. This pilot
study examines whether exercise-induced conditioning in
serum can directly affect tumor cells. It focuses on serum
collected before and after acute endurance exercise and its
impact in vitro. Participants underwent a 1 h endurance
training on a cycle ergometer. Samples were collected
before, after, and two hours post-exercise. MDA-MB-231 cells
were incubated with serum, and cell vitality and
proliferation were assessed. Cytokine arrays identified
relevant cytokine concentration changes. After identifying
CXCL9 as a possible contributor to inhibitory effects, we
inhibited the CXCR3 pathway and reassessed vitality.
Exercise-conditioned serum significantly reduced cell
vitality and proliferation post-intervention and after
resting. Cytokine arrays revealed changes in multiple
concentrations, and the inhibition of CXCL9 resulted in
growth inhibitory effects. Our findings suggest that serum
conditioned by an endurance intervention causes changes in
cancer cell growth. Based on our observations, the
alterations in serum cause growth-inhibitory effects,
possibly mediated through the CXCR3 axis. This study
provides preliminary evidence supporting the role of
exercise in modulating the cancer cell growth directly by
changes in serum.},
