Adenosine Triphosphate 61-83 thymidine kinase 2 Homo sapiens 30-32 1433372-6 1992 By calculating the percent of TK activity in the presence of adenosine triphosphate (ATP) or cytidine triphosphate (CTP), we estimated the relative contributions of TK isozymes TK1 and TK2 to total TK activity. Adenosine Triphosphate 85-88 thymidine kinase 2 Homo sapiens 30-32 1433372-8 1992 Calculations of the percent of TK activity in the presence of ATP or CTP showed that this elevation was due to increased TK1 isozyme levels. Adenosine Triphosphate 62-65 thymidine kinase 2 Homo sapiens 31-33 1433372-10 1992 ER- patients with recurrence had significantly (P < .001) elevated total tumor TK levels compared with levels in those who did not have recurrence, and calculation of percent of TK activity with ATP or CTP indicated elevated TK1 levels. Adenosine Triphosphate 198-201 thymidine kinase 2 Homo sapiens 181-183
