Abstract
Osteosarcoma (OS) faces a high metastatic burden, limited effective treatments, and a lack of specific therapeutic targets. In this prospective study, we established a human osteosarcoma cell (HOS) model overexpressing lncRNA FEZF1-AS1 (OE FEZF1-AS1), and subsequently obtained FEZF1-AS1-affected transcriptome data using high-throughput RNA sequencing (RNA-seq). OE FEZF1-AS1 promoted HOS cell proliferation and invasion, upregulated 125 genes, suppressed 48 genes, and impacted 1156 alternative splicing events (ASEs), including pathways like C-type lectin receptor signaling and Yersinia pestis infection. LncRNA FEZF1-AS1 plays a pivotal role in promoting the proliferation and invasion of HOS cells. Moreover, our study provides a comprehensive gene screening approach for identifying potential targets of FEZF1-AS1, emphasizing their regulatory mechanisms and ASEs in OS.
