SNHG1 and cholangiocarcinoma: When a detailed characterization of expressed lncRNAs in CCA, analysis of The Cancer Genome Atlas CCA, as well as typical tissue RNA-Sequencing data (including 9 normal as well as 36 cancer specimens) in addition to one independent microarray dataset from the Gene Expression Omnibus (GSE76297; 92 cancer tissue specimens as well as 91 normal tissue specimens), revealed the fact that SNHG1 expression is augmented in tumor tissues in comparison with the nearby tissues (Fig. 1a, b).
