The Relationship of p62 Gene Expression with Integrity of Mitochondrial DNA and the Level of Lipid Peroxidation Products in Skeletal Muscles of Rats of Different Ages Exposed to Different Feeding Protocols

  • Published:
Bulletin of Experimental Biology and Medicine Aims and scope

Sequestosome-1 (SQSTM1/p62) is one of the most important multifunctional proteins, which is necessary to maintain mitochondrial stability by eliminating damaged mitochondria through mitophagy. We studied the influence of age and diet on the expression of the p62 gene in the femoral and abdominal muscles of rats, as well as the integrity of some mitochondrial components. In the femoral muscles of 24-month-old rats receiving restricted ration, the expression of the p62 gene increased. We assume that activation of mitophagy contributed to a decrease in the levels of oxidative damage to mitochondrial DNA and LPO intensity in the femoral muscles of 24-month-old rats.
