In SAM analysis to identify significantly differentially expressed genes score and q-value parameters were used. Results. The largest increase in expression of genes was shown by MMP9, ADAM17, EphA2, and TIMP. Conclusions. Presented genes, especially ADAM17, MMP9, EphA2, TIMP1, ICAM 11, and CD4, may be used as prognostic markers of advanced stages of colorectal cancer, contributing to the development of new lines of therapy focused on reducing metastasis of the primary tumor. The gene discussed is CD4; the disease is colorectal cancer.
