Early intervention exercise training does not delay prostate cancer progression in Pten−/− mice

Abstract

Background: There is convincing evidence that men with advanced prostate cancer experience improved quality of life as a result of exercise therapy, although there is limited preclinical, and no clinical, data to directly support the notion that exercise training improves prostate cancer prognosis or outcome. The aim of this study was to investigate the effect of regular exercise training on the early stages of prostate cancer progression, as well as assessing whether alterations to prostate cancer metabolism are induced by exercise. Methods: Mice with prostate-specific deletion of Pten (Pten−/−) remained sedentary or underwent 6 weeks of endurance exercise training or high-intensity exercis..
