Exosomal miR-214-3p as a potential novel biomarker for rhabdoid tumor of the kidney

This study identifies exosomal miR-214-3p as a promising biomarker for rhabdoid tumor of the kidney, a rare aggressive pediatric renal malignancy. Using miRNA sequencing and validation in cell lines and xenograft models, researchers demonstrated significantly elevated miR-214-3p levels in RTK compared to neuroblastoma and normal renal cells, offering potential for improved differential diagnosis.
