Urinary detection of therapy-induced senescence and fibrosis using an injectable albumin-based nanoprobe Hartono M et al., Nature Aging 2026 Brief Summary provided by the authors: A novel urine test has been developed to detect a biochemical signal associated with senescence-related processes in diseased lung tissue. Matrix metalloproteinase-7 (MMP-7) was identified as a key marker linked to senescence-associated activity in lung cancer biology, particularly in the context of
