COL1A2 and colorectal carcinoma: Table 4 and Figure 3 show the obtained results. Expression levels of COL1A2 and KRT19 significantly increased in CRC and RC with respect to healthy donors (CRC: COL1A2, 32.11 ± 51.92, p-value < 0.0001; and KRT19, 12.06 ± 18.35, p-value = 0.0054; RC: COL1A2, 9.82 ± 6.50, p-value = 0.0088 and KRT19, 8.50 ± 4.75, p-value = 0.0008). In the group denominated Others, only COL1A2 was significantly increased (16.58 ± 17.14, p-value = 0.0044).
