Reduced expression of OTC and ASS1 in CRC. (A) OTC and (B) ASS1 H-score were assessed on CRC TMA. Representative histo-spots are shown on the left. The bar graphs indicate H-score distribution according to Duke’s stage, whereas the distribution of protein expression within the whole TMA cohort is reported in the pie chart. *P < 0.05 (C) Western blot analysis of OTC and ASS1 after 72 h treatment with 5 µM 5-Azacytidine (5-AZA). Human liver extract was used as positive control for urea cycle enzymes, actin was used as endogenous loading control. Original western blots are reported in Supplementary Fig. S15.
