The genome-wide co-expression analyses showed that the expression levels of collagen genes (COL1A1, COL1A2, COL5A1, COL5A2, COL8A1 and COL8A2) and LincRNAs (Linc01614 and Linc01711) were significantly positively correlated with PODNL1 expressions in various cancers (Figure 12). This evidence concerns the gene COL1A1 and cancer.
