MT-Exo-derived miR-4651 and miR-6126 coordinately regulate the SRSF1-progerin and SP1-PrPᶜ axes to attenuate vascular aging in HGPS.
Hutchinson-Gilford progeria syndrome (HGPS) is characterized by progressive vascular injury that remains incompletely controlled by therapies targeting progerin-associated pathology. Here, we investigated the therapeutic activity and molecular mechanisms of melatonin-preconditioned mesenchymal stromal cell-derived smal...
