Given the critical role of CD8+ T cells in immune-mediated tumor rejection and as a prognosis factor in many solid tumors, we next determined, using RT-qPCR analysis, the levels of SERPINE1 and CD8A, a cell surface receptor found on cytotoxic T lymphocytes, in 20 surgical COAD specimens. The gene discussed is SERPINE1; the disease is colon adenocarcinoma.
