〔Abstract〕 Objective To investigate the regulatory relationship between long non-coding RNA LINC01578 and c-Myc, and to explore the effect of LINC01578 on the metabolic process of oral squamous cell carcinoma(OSCC). Methods After c-Myc was knocked down in OSCC cell line CAL27, LINC01578, a long non-coding RNA that is positively regulated by c-Myc, was identified by high-throughput sequencing technology. qRT-PCR was employed to measure the expression levels of c-Myc and LINC01578 in OSCC tissues and adjacent normal tissues. Following overexpression or knockdown of c-Myc in CAL27 and HN6 cells, qRT-PCR was conducted to validate the consistency with sequencing results. The binding of c-Myc to the LINC01578 promoter was confirmed using a dual luciferase reporter assay. Seahorse, ATP production and lactate production assays were utilized to examine the impact of c-Myc on glucose metabolism in OSCC via LINC01578. Colony formation assays assessed the proliferative capacity of OSCC cell lines. Results qRT-PCR analysis revealed significantly higher expression levels of c-Myc and LINC01578 in OSCC tissues compared to adjacent tissues(P
