in tissues obtained from patients undergoing gastrectomy , the activities of 12 enzymes involved in pyrimidine nucleotide synthesis : cytidine triphosphate ( ctp ) synthetase , deoxycytidine monophosphate ( dcmp ) deaminase , thymidine monophosphate ( dtmp ) kinase , uridine ( urd ) , deoxycytidine ( dcyd ) and thymidine ( dthd ) kinases , urd , deoxyuridine ( durd ) and dthd phosphorylases , cytidine ( cyd ) and dcyd deaminases , and dna polymerase were examined in the eight-well-differentiated and 12 poorly differentiated gastric cancer tissues and the ten normal tissues .
