Dysfunction of these genes and the associated activation of transposable elements adversely affect reproductive development and quality of life. The role of transposons in contrast to retrotransposons and their interaction with genes of the Argonaute family in aging processes have not been studied. This study considers a scenario in which the piwi and aub genes in the presence of functional hobo transposons can modify the effects from the level of DNA damage to lifespan. The simultaneous presence of mutation (piwi or aub) and hobo (regardless of size) in the genome has practically no effect or (less often) leads to a decrease in the level of DNA damage in ovarian cells. A high level of sterility and low ovarian reserve were noted mainly with a combination of mutations and full-sized hobo elements. The combination of these two genetic factors negatively affects the fertility of young females and embryonic survival. Isolated cases of restoration of reproductive functions with age were noted but only in females that had low fertility in the early period of life. The presence of hobo transposons contributed to an increase in the lifespan of both mutant and non-mutant females. Dysfunction of the piwi and aub genes (without hobo) can reduce the lifespan of both sexes. Together, each mutation and hobo transposons act antagonistically/additively (in females) and synergistically/antagonistically (in males) to change the lifespan. In parameters of locus-specific instability, hobo activation was more pronounced in piwi gene dysfunction. The results obtained complement data on the study of new functions of Argonaute family genes and their interactions with transposable elements in the aging process.</p>","PeriodicalId":8909,"journal":{"name":"Biogerontology","volume":" ","pages":"131-146"},"PeriodicalIF":4.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49673916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rate of aging and age-related pathology are modulated by stress responses and repair pathways that gradually decline with age. However, recent reports indicate that exceptional longevity sustains and may even enhance the stress response. Whether normal and exceptional aging result in either attenuated or enhanced stress responses across all organs is unknown. This question arises from our understanding that biological age differs from chronological age and evidence that the rate of aging varies between organs. Thus, stress responses may differ between organs and depend upon regenerative capacity and ability to manage damaged proteins and proteotoxicity. To answer these questions, we assessed age-dependent changes in brain stress responses with normally aged wild type and long-lived Dwarf mice. Results from this study show that normal aging unfavorably impacts activation of the brain heat shock (HS) axis with key changes noted in the transcription factor, HSF1, and its regulation. Exceptional aging appears to preserve and strengthen many elements of HSF1 activation in the brain. These results support the possibility that reconstitution of aging brain stress responses requires a multi-factorial approach that addresses HSF1 protein levels, its DNA binding, and regulatory elements such as phosphorylation and protein interactions.</p>","PeriodicalId":8909,"journal":{"name":"Biogerontology","volume":" ","pages":"147-160"},"PeriodicalIF":4.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10794279/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10234968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the catalog of age-related proteins secreted by a single cell type in a single tissue would be useful for understanding tissue-specific aging patterns.

These cellular processes are tightly regulated physiologically, with FOXO3 acting as the hub that integrates signalling networks controlling them.
