Adult male Wistar rats were divided into two groups: sedentary or exercised fathers.

Epigenetic marks are modulated by gender and time of the day in the hippocampi of adolescent rats: A preliminary study.

Although the involvement of gender in epigenetic machinery in peripheral tissues during the neonatal period has been suggested, the gender-related epigenetic profile of brain areas during the adolescent period is rarely exploited. Furthermore, the influence of time of day on hippocampal acetylation marks has been demonstrated in young adult and aged rats; however, there are no studies reporting epigenetic changes in the adolescent period. Therefore, this study aimed to investigate the effects of gender on hippocampal DNA methyltransferase 1 content and histone deacetylase (HDAC) activity of adolescent rats at different time points, specifically early morning and afternoon.

Glial fibrillary acidic protein levels are associated with global histone H4 acetylation after spinal cord injury in rats.

Emerging evidence has suggested global histone H4 acetylation status plays an important role in neural plasticity. For instance, the imbalance of this epigenetic marker has been hypothesized as a key factor for the development and progression of several neurological diseases. Likewise, astrocytic reactivity - a well-known process that markedly influences the tissue remodeling after a central nervous system injury - is crucial for tissue remodeling after spinal cord injury (SCI).
