[Effects of mitophagy on aerobic exercise intervention for depression in rats].

This experiment was designed to observe the effects of aerobic exercise on depressive behavior in rats induced by chronic unpredictable mild stress (CUMS), and to explore the possible mechanism by detecting the proteins related to mitochondrial autophagy. SD rats were randomly divided into three groups: blank control group (C, =12), depression model group (D, =12) and post-depression exercise group (D+E, =12). Group D and D+E were modeled with CUMS for 28 days, and group D+E underwent aerobic exercise intervention for 4 weeks after model establishment.

Moderate-Intensity Intermittent Training Alters the DNA Methylation Pattern of PDE4D Gene in Hippocampus to Improve the Ability of Spatial Learning and Memory in Aging Rats Reduced by D-Galactose.

(1) Background: Aging is the main risk factor for most neurodegenerative diseases, and the inhibition of Phosphodiesterase 4(PDE4) is considered a potential target for the treatment of neurological diseases. The purpose of this study was to investigate the inhibitory effect of moderate-intensity intermittent training (MIIT) on PDE4 in the hippocampus of rats with D-galactose (D-gal)-induced cognitive impairment, and the possible mechanism of improving spatial learning and memory. (2) Methods: the aging rats were treated with D-Gal (150 mg/kg/day, for 6 weeks).
