HSPG2 and hepatocellular carcinoma: To investigate the role and therapeutic potential of glucose‐related lncRNAs in HCC, we performed conducted RNA‐sequencing (RNA‐seq) analysis of Huh7 and PLC cells cultured in low‐glucose (5 mM) or high‐glucose (25 mM) medium for 48 h and identified 569 lncRNAs whose expression changed significantly (FPKM > 0.5, fold change (=FPKM of high‐glucose/FPKM of low‐glucose) >1.5 or < 0.67) with alterations in glucose concentration (RNA‐seq dataset GSE234898).
