State of art in genetic of ageing is reviewed. Deciphering of human genome and recent advances in functional genomics contributed a lot to significant achievements in molecular medicine as well as in understanding of ageing mechanisms. Progressive transcriptome degeneration caused by expression modulations of specific aging genes underlies visible physiological, biochemical and hormonal changes in aging human bodies. Each human subject should be considered as physiological mosaic composed of the tissues and organs of different age. The existence of weak genetic chain confined to particular organ or tissue provides potential substrate for severe chronic disorders in aging people. Two main groups of the aging genes are highlighted: 1. Longevity genes identified in population studies of old people, and 2. The genes identified and proved in aging studies in experimental species. Already existing and feasible molecular approaches for extending of active human longevity are reviewed. They include targeted modulation of aging gene activity, as well as presymptomatic diagnostics and relevant preventive measures of severe and frequent multifactorial diseases. Combining of already known empirical methods of anti-aging medicine with unique genetic profile of each human (gene-pass) renders new awarding opportunities for the further advancements of human longevity programs.
本文综述了衰老遗传学的研究现状。人类基因组的破译以及功能基因组学的最新进展,为分子医学的重大成就以及衰老机制的理解做出了巨大贡献。特定衰老基因表达调控导致的渐进性转录组退化,是衰老人体中可见的生理、生化和激素变化的基础。每个人都应被视为由不同年龄的组织和器官组成的生理镶嵌体。局限于特定器官或组织的弱遗传链的存在,为老年人严重慢性疾病提供了潜在基础。文中重点介绍了两类主要的衰老基因:1. 在老年人人群研究中鉴定出的长寿基因;2. 在实验物种衰老研究中鉴定并证实的基因。本文还综述了已有的、可行的延长人类有效寿命的分子方法。这些方法包括对衰老基因活性的靶向调控,以及对严重且常见的多因素疾病的症状前诊断和相关预防措施。将抗衰老医学已知的经验方法与每个人独特的基因特征(基因通行证)相结合,为人类长寿计划的进一步推进带来了新的机遇。
