Cell-Surface LAMP1 is a Senescence Marker in Aging and Idiopathic Pulmonary Fibrosis

18 hours 23 minutes ago
The accumulation of senescent cells (SEN) with aging produces a chronic inflammatory state that accelerates age-related diseases. Eliminating SEN has been shown to delay, prevent, and in some cases reverse aging in animal disease models and extend lifespan. There is thus an unmet clinical need to identify and target SEN while sparing healthy cells. Here, we show that Lysosomal-Associated Membrane Protein 1 (LAMP1) is a membrane-specific biomarker of cellular senescence. We have validated...

Sarcopenia and osteoporosis

18 hours 23 minutes ago
Sarcopenia and osteoporosis are common, interconnected conditions, in aging populations that lead to increased frailty, disability and a heightened risk of falls and fractures. Sarcopenia is the progressive loss of muscle mass, strength and function, that often coexists with osteoporosis, which is characterized by reduced bone strenght for a decreased bone mineral density (BMD) and altered bone quality. Together, these conditions form a clinical syndrome known as osteosarcopenia. Both disorders...

Multinational evaluation of AnthropoAge as a measure of biological age in the USA, England, Mexico, Costa Rica, and China: a population-based longitudinal study

2 days 18 hours ago
We validated AnthropoAge, a biological age (BA) metric, for prediction of mortality and age-related outcomes using harmonized data from the US, England, Mexico, Costa Rica, and China. We estimated AnthropoAge and AnthropoAgeAccel as proxies of BA and age acceleration using body mass index and waist-to-height ratio. We compared mortality prediction of AnthropoAge vs. chronological age (CA) using Cox models and assessed its association with age-related outcomes with generalized estimating...
