Title

Chronic stress-induced apoptosis is mitigated by young mitochondria transplantation in the prefrontal cortex of aged rats

Pages

  725-730

Abstract

 Objective(s): Apoptosis is common and often comorbid with Aging and stress-related mood disorders. Evidence suggests that fresh Mitochondria could reverse age-related dysfunctions in organs, especially in the brain. Therefore, this study investigated the effect of young Mitochondria administration on the Apoptosis process in the prefrontal cortex (PFC) of aged Rats exposed to Chronic stress. Materials and Methods: Aged (22 months old) male Rats were randomly assigned into four groups: aged control (AC), aged Rats treated with young Mitochondria (A+M), aged Rats subjected to Chronic stress for four weeks (A+St), and aged Rats subjected to Chronic stress and treated with young Mitochondria (A+St+M). A+M and A+St+M groups received a single ICV injection (10 μ, l) of fresh Mitochondria isolated from the brain of young Rats for five minutes (2 μ, l/min). Finally, the levels of Malondialdehyde (MDA), Cytochrome c (Cyt c), Bax, Bcl-2, and Caspase-3 expression were investigated in the PFC. Results: Young Mitochondria administration reduced neuronal Apoptosis in the PFC, associated with down-regulation of MDA, Bax, and Caspase-3 and up-regulation of Bcl-2. Moreover, fresh Mitochondria partially improved the Chronic stress-induced Mitochondrial dysfunction in aged Rats, as indicated by reduced cytochrome c (Cyt c) release from the Mitochondria. Conclusion: These results suggest mitotherapy could reverse cell viability and Mitochondrial dysfunction-induced Apoptosis in the PFC tissue of aged Rats subjected to stressful stimuli.
