Table 1 lists several key lncRNAs, such as MALAT1, UCA1, HULC, HOTTIP, CCAT1, CCAT2, and H19, and their identified associated proteins, mentioning methods used for their isolation and identification. These proteins serve as potential biomarkers for the treatment of liver and colorectal cancer patients [31–34]. Additionally, one notable example is the long non-coding RNA Highly Upregulated in Liver Cancer (HULC). This evidence concerns the gene HULC and liver cancer.
