| Abstract | Lifespan is a complex quantitative trait, which makes a significant contribution to Darwinian fitness. The understanding of the genetic structure of longevity is a fundamental problem of the evolution of ontogeny, evolutionary genetics, and molecular gerontology. Under optimal conditions, lifespan is determined by the aging rate. Aging is made up of interrelated processes that occur at the organismal, tissue, cellular, molecular, and genetic levels. The disturbances touch homeostasis maintenance, metabolic reactions, and transduction of intra and intercellular signals. Its other consequences are the accumulation of senescent cells, damaged organelles, and macromolecules; epigenetic changes; and genetic instability. This review summarizes the current knowledge of the major genetic determinants of longevity and aging. It considers genes and signaling pathways that regulate stress response, metabolism, the growth of cells and the body, preservation of genome and proteome integrity, qualitative and quantitative mitochondrion composition, inflammatory response, apoptosis, selection of viable cells, and circadian rhythms. The redistribution of energy resources from one pathway to another can induce or inhibit the “longevity program,” improving stress resistance and slowing down senescence. Approaches to slowing aging and achieving healthy longevity are outlined based on the analysis of the geroprotective potential of the regulation of the examined genes. These trends include heterochromatin recovery; retrotransposition suppression; aneuploidy elimination; restoration of lysosome acidity; telomere extension; suppression of chronic inflammation; elimination of protein crosslinks; elimination of senescent cells; recovery of NAD$^{+}$ levels; inhibition of mTOR, S6K, TGFβ, and AT1; and controlled activation of the longevity program genes FOXO, AMPK, PGC1α, and NRF2. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
