However, the functional roles of Meflin in fibroblasts remain unclear. To investigate the functional impact of Meflin expression in fibroblasts, RNA sequencing was performed on Meflin-overexpressing NHDF-Ad cells cultured under conditions that better mimic the in vivo tumor microenvironment, using a cell accumulation technique that accurately recapitulates the fibrotic stroma observed in aggressive human cancers. Meflin overexpression resulted in the downregulation of PDPN, a well-established marker of tumor-promoting CAFs, and upregulation of DPT and COL15A1, which are markers of universal fibroblasts that resemble normal fibroblasts and are considered a potential source of diverse fibroblast subtypes.These findings suggest that high-level expression of Meflin is crucial for skewing CAFs toward a more universal fibroblast–like state.","dates":{"publication":"2026/01/11"},"accession":"GSE301570","cross_references":{"GSM":["GSM9085479","GSM9085480","GSM9085483","GSM9085484","GSM9085481","GSM9085482","GSM9085485","GSM9085486"],"GPL":["34284"],"GSE":["301570"],"taxon":["Homo sapiens"]}}
