研究概览

Osteosarcoma is one of the malignant tumors in children and adolescents patients. Our findings indicate that exosomal miR-21-5p could potentially serve as a therapeutic target in osteosarcoma, providing initial evidence for further clinical investigation.

核心发现

Single-cell RNA sequencing analysis of GSE162454 revealed the crucial role of CAFs in the pathogenesis of osteosarcoma.

Tissue exosomal miRNA sequencing unveiled significant differential expression of miR-21-5p.

Subsequently, aberrant upregulation of exosomal miR-21-5p exhibited a strong correlation with advanced clinical stage and poor prognosis in osteosarcoma.

Further experiments in vitro indicated that elevated levels of miR-21-5p significantly enhanced proliferation and migration of osteosarcoma cells by suppressing ferroptosis.

研究设计

Single-cell RNA sequencing was employed to characterize the microenvironment of osteosarcoma.

Tissue exosomal miRNA sequencing was conducted on tumor tissues and adjacent normal tissues to screen for abnormal expression of exosomal miRNAs.

WGCNA analysis was used to identify target exosomal miRNAs.
