These genes were associated with the process of collagen fibril organization(GO:0030199)(COL1A1,COL3A1,COL1A2,COL5A1,COL11A1),blood vessel development(GO:0001568)(COL1A1,COL3A1,COL1A2,COL5A1,MMP2,BGN,COL8A1,THY1),cell adhesion(GO:0007155)(COL3A1,COL5A1,COL11A1,TGFB1I1,CDH11,COL6A3,COL8A1,AEBP1,THY1,THBS2), extracellular matrix organization(GO:0030198)(COL1A1,COL3A1,COL1A2,COL5A1,COL11A1,PXDN), collagen biosynthetic process(GO:0032964)(COL1A1,COL3A1,COL5A1) in bladder cancer. This evidence concerns the gene COL1A2 and urinary bladder cancer.
