Of the 29 genes expressed above two-fold in the carcinomatosis group compared to primary carcinomas and liver metastases, several of the genes found were of interest in relation to cancer biology, such as the upregulation of DKFZp564I1922 (alias adlican), and CTGF, and the reduced expression of CCNE1, CHC1, and MYOHD1. The gene encoding the hypothetical protein adlican is previously seen highly expressed in colorectal cancer compared to normal tissue [39]. The gene discussed is RCC1; the disease is colorectal cancer.
