Abstract :

Approximately 1% of the world's population is affected by schizophrenia (SZ), a chronic and debilitating neurodevelopmental disorder. Recent evidences have been suggesting a pivotal role of epigenetic imbalance on SZ physiopathology. Interestingly, exercises are able to modulate epigenetic mechanisms in different populations, however, there are no reports conducted with SZ patients. Then, the present study sought to investigate the effect of exercise on global histone H4 acetylation levels in peripheral blood of SZ individuals. This study was approved by the Research Ethics Committee of the Centro Universit├?┬írio Metodista do IPA (no 1.243.680/2015). The participants (n=15) were submitted to a concurrent exercise protocol (CEP) during 90 days, 3 times a week for 60 minutes. In order to evaluate the acute and chronic exercise outcomes, blood samples were collected in different time points: pre, 30, 60 and 90 days after intervention. All analysis was done in leukocytes using specific commercial kits, according to the manufacturer's instructions. It was observed that a significant decrease in global H4 histone acetylation levels 30 days (4160.74├?┬▒1402.58 ng/mg of protein; p=0.005), 60 days (4979.32├?┬▒1849 ng/mg of protein; p=0.007) and 90 days (6528.61 ├?┬▒ 4893.95 ng/mg of protein; p=0.030) after intervention. Our findings demonstrated that CEP can induce a hypoacetylation status in leukocytes of SZ individuals, an indicative of reduced transcription and expression of specific genes.
