Biogerontology in Ukraine: update

Area of Science:

• Biogerontology
• Molecular Biology
• Gerontology

Background:

• Aging research in Ukraine traditionally focused on neuro-humoral regulation, immune system, adaptation, and oxidative stress.
• Mitochondria and oxidative stress are central to understanding aging mechanisms and lifespan extension.
• International collaboration is essential for addressing complex aging challenges.

Purpose of the Study:

• To review recent biogerontological findings in Ukraine.
• To highlight efficient modes of cooperation in aging research.
• To synthesize conclusions from multidirectional investigative endeavors.

Main Methods:

• Analysis of mitochondrial DNA base composition and nuclear DNA insertions (NUMTs).
• Investigation of mitochondrial membrane modifications and reactive oxygen species (ROS) generation.
• Assessment of antioxidant gene and enzyme coordination.
• Exploration of the lateral hypothalamic area's role in aging.
• Evaluation of lymphoid tissue microenvironment effects on cell transplantation.
• Study of gene and polypeptide therapy for accelerated aging.
• Research on artificial atmosphere effects on lifespan and viability.

Main Results:

• Mitochondrial DNA composition and NUMTs correlate significantly with mammalian maximum lifespan.
• Mitochondrial membrane modifications impact ROS generation, metabolism, and lifespan.
• Coordinated action of antioxidant genes and enzymes is vital for successful aging.
• The lateral hypothalamic area may function as a central anti-aging region in the CNS.
• Lymphoid tissue microenvironment influences transplanted cell functionality.
• Gene and polypeptide therapies show potential for treating accelerated aging.
• Optimized artificial atmospheres can extend lifespan and enhance viability.

Conclusions:

• Mitochondrial function and oxidative stress are key targets for aging interventions.
• Successful aging depends on coordinated antioxidant defenses and specific CNS regions.
• Therapeutic strategies like gene/polypeptide therapy and environmental control offer promising avenues for life extension.
