Fibroblasts derived from individuals with Down syndrome (DS) exhibit elevated DSCR3 expression at both the mRNA and protein levels, correlating with increased cell volume compared to fibroblasts from healthy donors. Despite a slower proliferation rate, DS fibroblasts demonstrate higher basal and maximal mitochondrial respiration, suggesting enhanced metabolic activity associated with increased cell size. siRNA\u2010mediated knockdown of DSCR3 reduces cell size in both DS and normal fibroblasts, indicating its general role in cell size regulation. As DSCR3 is a component of the retriever complex involved in endosomal cargo recycling, these findings position membrane protein trafficking as a novel module for cell size control.<\/jats:p>","DOI":"10.1111\/gtc.70142","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T07:39:32Z","timestamp":1786693172000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Identification
