SkQ1 as a Tool for Controlling Accelerated Senescence Program: Experiments with OXYS Rats

Area of Science:

• Gerontology
• Mitochondrial Biology
• Pharmacology

Background:

• Aging is conceptualized as programmed death (phenoptosis).
• Mitochondrial dysfunction is linked to accelerated senescence.
• Reactive oxygen species (ROS) generation in mitochondria is implicated in aging.

Purpose of the Study:

• To evaluate the efficacy of mitochondrial antioxidant SkQ1 in inhibiting accelerated senescence.
• To investigate SkQ1's effects on age-related diseases in OXYS rats.
• To explore the mechanisms underlying SkQ1's anti-aging properties.

Main Methods:

• Administration of SkQ1 to OXYS rats exhibiting accelerated senescence.
• Assessment of age-related disease manifestations (cataracts, retinopathy, osteoporosis, Alzheimer's signs).
• Analysis of mitochondrial function and signaling pathways.

Main Results:

• SkQ1 effectively suppressed accelerated senescence and its associated diseases in OXYS rats.
• SkQ1 prevented/suppressed cataracts, retinopathy, osteoporosis, and Alzheimer's-like symptoms.
• SkQ1's primary effect is linked to restoring mitochondrial structure and function, independent of direct oxidative stress reduction.

Conclusions:

• SkQ1 is a potent inhibitor of accelerated phenoptosis (aging).
• SkQ1 demonstrates therapeutic potential for preventing multimorbidity associated with early aging.
• SkQ1 represents a promising strategy for individuals predisposed to premature age-related diseases.
