COL1A2 and urinary bladder cancer: They were also associated with the pathways of ECM-receptor interaction(hsa04512)(COL3A1, COL6A3, COL1A2, COL1A1, COL11A1, THBS2, COL5A1), protein digestion and absorption(hsa04974)(COL3A1, COL6A3, COL1A2, COL1A1, COL11A1, COL5A1),focal adhesion(hsa04510)(COL3A1, COL6A3, COL1A2, COL1A1, COL11A1, THBS2, COL5A1),and PI3K-Akt signaling pathway(hsa04151)(COL3A1, COL6A3, COL1A2, COL1A1, COL11A1, THBS2, COL5A1) in bladder cancer.
