    Osteosarcoma (OS), a metastatic cancer prevalent in youth with grim prognosis, is modulated by long non-coding RNAs (lncRNAs), notably C1QTNF1-AS1, an oncogene associated with multiple tumors. This research focused on elucidating the functional roles and underlying mechanisms of C1QTNF1-AS1 in OS cells.Leveraging bioinformatics, miR-34a-5p was pinpointed as specifically interacting with C1QTNF1-AS1 while also targeting LDHA and PDK3, validated via dualluciferase assays and RNA immunoprecipitation. Expression analysis using qRT-PCR and Western blot in OS cells revealed intricate interplay among C1QTNF1-AS1, miR-34a-5p, LDHA, and PDK3. Functional evaluations demonstrated that C1QTNF1-AS1 silencing upregulated LDHA and PDK3, partially offset by miR-34a-5p mimics.Inhibition of C1QTNF1-AS1 accelerated OS cell proliferation, motility, invasion, and the Warburg effect, whereas miR-34a-5p overexpression alleviated these effects. In summary, our findings underscore C1QTNF1-AS1's pivotal role in OS pathogenesis.Its downregulation indirectly upregulates LDHA and PDK3 through miR-34a-5p suppression, thereby fostering OS progression by enhancing glycolytic metabolism and cancer cell behaviors including growth, migration, and invasion.
