Given the differential expression of MDL1AS between rectal cancer cells and the surrounding normal tissue (Figure 1A) and that the differences in levels of expression for this lncRNA were almost significant in patients with long survival when compared to those with lower survival (p = 0.053, Table 1), we decided to study more deeply the connections between the expression of MDL1/MDL1AS and LARC patient survival. This evidence concerns the gene CLEC5A and rectal cancer.
