Abstract
Osteosarcoma (OS) is a malignant bone tumor that originates from interstitial tissues and affects the health of children and adolescents. Long noncoding RNAs (lncRNAs) are an intriguing category of widely distributed endogenous RNAs involved in OS progression, many of which remain functionally uncharacterized. Herein, we observed an increased expression of lncRNA SPINT1-AS1 in OS tissues and cell lines. Further analysis confirmed that SPINT1-AS1 promotes the proliferation and metastasis of OS cells. Moreover, miR-135b-5p was identified as a downstream target of SPINT1-AS1. Through bioinformatics analysis, PGAM1 mRNA was validated as a target of miR-135b-5p via RIP and luciferase reporter assays. SPINT1-AS1 could enhance OS cell proliferation and metastasis by promoting aerobic glycolysis, acting as a ceRNA by binding to miR-135b-5p, thereby increasing PGAM1 expression. Taken together, these results indicate that SPINT1-AS1 functions as a tumor promoter and regulates OS cell progression through the miR-135b-5p/PGAM1 axis.
期刊介绍:
Cancer Cell International publishes articles on all aspects of cancer cell biology, originating largely from, but not limited to, work using cell culture techniques.
The journal focuses on novel cancer studies reporting data from biological experiments performed on cells grown in vitro, in two- or three-dimensional systems, and/or in vivo (animal experiments). These types of experiments have provided crucial data in many fields, from cell proliferation and transformation, to epithelial-mesenchymal interaction, to apoptosis, and host immune response to tumors.
Cancer Cell International also considers articles that focus on novel technologies or novel pathways in molecular analysis and on epidemiological studies that may affect patient care, as well as articles reporting translational cancer research studies where in vitro discoveries are bridged to the clinic. As such, the journal is interested in laboratory and animal studies reporting on novel biomarkers of tumor progression and response to therapy and on their applicability to human cancers.
