However, HULC, which played oncogenic roles in several cancers, including liver cancer and prostate cancer [31, 32], demonstrated no significant expression difference between LSCC tumors and corresponding normal tissues in the present study, indicating that the expression pattern of lncRNAs may have cell-type specificity, and further studies should be addressed to detect the roles of tumor-specific lncRNAs. This evidence concerns the gene HULC and liver cancer.
