چکیده انگلیسی
The study investigated the effects of exercise on epigenetic signals and systemic cytokine levels in chronic obstructive pulmonary disease (COPD) individuals. Ten participants of a pulmonary rehabilitation program were submitted to 24 sessions of a supervisioned exercise protocol thrice-weekly (90 min/session). Blood samples were collected at baseline, after the 1st session, before and after the 24th session. A DNA hypomethylation status was observed after the 1st session when compared at baseline, while global histone H4 acetylation status was unaltered in any time-points evaluated. No significant changes were observed on cytokine levels after the 1st session. A significant enhancement on interleukin 6 (IL-6) and a decrease on transforming growth factor-beta (TGF-β) levels were found after the 24th session when compared to the pre 24th session. Moreover, 23 sessions of exercise were able to diminish significantly the basal levels of IL-6 and interleukin 8 (IL-8). These data suggest a potential role of epigenetic machinery in mediating the anti-inflammatory effects of exercise in COPD patients.
