COL6A3 and colorectal cancer: Similarly, we found that COL6A3 gene expression was increased in colorectal cancer tissues comparing with normal tissues by analyzing Hong Colorectal (p = 5.2E-7) [28], Kaiser Colon (p = 0.016) [29], Ki Colon (p = 4.3E-6) [30], Skrzypczak Colorectal 2 (p = 0.0002) [31], Skrzypczak Colorectal (p = 0.004) [31] and TCGA Colorectal (p = 0.006) (Figure 4F–4K).
