Aging is a complex process manifesting at molecular, cellular, organ, and organismal levels. It leads to functional decline, disease, and ultimately death, but the relationship between these fundamental biomedical features remains elusive. By applying elastic net regularization to plasma proteome data of over 50,000 human subjects in the UK Biobank and other cohorts, we report interpretable organ-specific and conventional aging models trained on chronological age, mortality, and longitudinal proteome data.

Ghrelin modulates several biological functions via selective activation of the growth hormone secretagogue receptor (GHSR). GHSR agonists may be useful for the treatment of anorexia and cachexia, while antagonists and inverse agonists may represent new drugs for the treatment of metabolic and substance use disorders. Thus, the identification and pharmacodynamic characterization of new GHSR ligands is of high interest.

Article Synopsis
  • Circulating plasma proteins are crucial for human health and can help measure biological age, which may predict risks for age-related diseases and overall mortality.
  • A study using data from the UK Biobank identified 204 proteins that accurately predict chronological age and are linked to 18 chronic diseases, as well as various health measures such as cognitive function and frailty.
  • The findings were validated in studies from China and Finland, showing that this proteomic age clock can reliably assess age-related health risks across different populations.

Invasive group A streptococci infections are increasing worldwide, mainly due to the emm1 lineage M1 UK emergence. Although this variant has recently been described in adult Italian patients, its circulation in children has not yet been established. Characterizing by whole genome sequencing 6 invasive group A streptococci strains isolated between 2022 and 2023, we highlighted M1 UK lineage circulation in pediatric patients in Italy.
