Colon cancer patients with IRS of TRPS1 protein more than the median expression level (4.5) were assigned to the high TRPS1 expression group (mean expression value 5.2, n = 56), and those samples with IRS equal or below the median value were assigned to the low TRPS1 expression group (mean expression value 3.8, n = 44). Here, IARS1 is linked to malignant colon neoplasm.
