Mechanism of Swimming Exercise Intervention on Rats with Vascular Dementia Based on PERK/ATF4/CHOP Pathway by LIU Fang, LI Mengxing, WANG Yu, TANG Wei

“…Compared with the model group, the average escape latency of the swimming exercise group and the drug group were significantly shortened, and the number of platform crossing significantly increased (<italic>P</italic>&lt;0.05). (2) Neuron ultrastructure: in the model group, the number of organelles in the cytoplasm decreased, cytoplasmic matrix dissolution and vacuolization occurred, mitochondria cristae were broken and unclear, and neural fiber necrosis and dissolution were visible; compared with the model group, the swimming exercise group showed significant improvement in the structure of various organelles in the cytoplasm and the degree of vacuolar changes. (3) Expression levers of brain tissue PERK, ATF4, CHOP mRNA and protein: compared with the sham operation group, the expression levels of PERK, ATF4, CHOP mRNA, and protein in the hippocampal CA1 region of the model group significantly increased (<italic>P</italic>&lt;0.05); compared with the model group, the expression levels of PERK, ATF4, CHOP mRNA and protein in the hippocampal CA1 region of the swimming exercise group significantly decreased (<italic>P</italic>&lt;0.05).ConclusionSwimming exercise can protect brain tissue in rats with VD and improve their cognitive functions. The mechanism may be related to the regulation of the PERK/ATF4/CHOP pathway, suppressing the expression of ERS-related proteins PERK, ATF4, CHOP mRNA and protein in the hippocampal region of rats with VD.…”
