The following results suggested that MK2 depletion in CD8+ T cells enhances expression of anti-tumorigenic factors in pancreas and colon cancers, we examined molecules released from PK5L1940 and BRAF cells-derived allograft tumors obtained from control mice and animals treated with WT or MK2 KO CD8+ T cells. This evidence concerns the gene BRAF and malignant colon neoplasm.
