Fig. 4From: Molecular profile of 5-fluorouracil pathway genes in colorectal carcinomaProtein expression of DPYS and UPB1 in tumors of colorectal cancer patients. Protein expression of DPYS (a) and UPB1 (b) was assessed by immunoblotting with normalization to actin in the representative set of tumors with highest and lowest methylation levels as described in Materials and Methods Back to article page
