Telomeres and sirtuins are independently implicated in causing disease and aging, but how they cooperate is not well understood. A recent study demonstrates that telomere shortening represses sirtuins and increasing sirtuin activity stabilizes telomeres and improves telomere-dependent disease, suggesting that these two pathways are tightly intertwined.

In this study, we explored the potential application of [d-Ala2, d-Leu5]-enkephalin (DADLE) in anti-ageing field in response to the trend of increasing global population ageing. We aimed to reveal experimentally whether DADLE can positively affect the lifespan and health of aged mammals through its unique anti-inflammatory or metabolic mechanisms. Forty-two female C57/BL6J mice aged 18 months were intraperitoneally injected with DADLE or normal saline for 2 months.

The number of infertile couples undergoing in vitro fertilisation (IVF) has increased significantly. The efficacy of this procedure is contingent upon a multitude of factors, including gamete quality. One factor influencing gamete quality is oxidative stress, which leads to telomere damage and accelerates cellular ageing.

Due to its peculiar structure and function, the cardiovascular system is particularly vulnerable to the detrimental effects of ageing. Current knowledge about the molecular mechanisms of ageing revealed the processes actively promoting ageing, e.g.

Obesity is a global health concern owing to its association with numerous degenerative diseases and the fact that it may lead to early aging. Various markers of aging, including telomere attrition, epigenetic alterations, altered protein homeostasis, mitochondrial dysfunction, cellular senescence, stem cell disorders, and intercellular communication, are influenced by obesity. Consequently, there is a critical need for safe and effective approaches to prevent obesity and mitigate the onset of premature aging.
