Similar observations were made for lncRNAs DANCR, ATB, lincRNA-ROR, SNHG20 and GAS5 all of which have also been shown to correlate with poor prognosis of colorectal cancers (Yin et al., 2014; Liu et al., 2015; Li et al., 2016b; Yue et al., 2016; Zhou et al., 2016) but we did not find them to be expressed at significantly different levels in metastases compared to the adjacent normal tissue. This evidence concerns the gene SNHG20 and colorectal cancer.
