Definitions
- the present invention relates to a novel antibody against human orthophosphate phosphoribosyltransferase and a method for measuring human orthophosphate phosphoribosyltransferase protein using the antibody.
- Orotate phosphoribosyl transferase (EC2. 4. 2. 10, hereinafter referred to as “OPRT”) catalyzes the reaction to produce uridyl monophosphate (UM P) from orotate It is an enzyme that plays a role in supplying pyrimidine nucleotides essential for nucleic acid synthesis, and is one of the main rate-limiting enzymes in the nucleic acid precursor supply pathway. Therefore, it is known that its activity is high in tumor tissue and gastrointestinal epithelium where cell proliferation is active.
- 5-fluorouracil anticancer agents are activated using OPRT as a rate-determining enzyme and exert an antitumor effect, so that the effect is significant for patients with large amounts of OPRT in tumor cells. It is known that the effect of prolonging life is observed, but the effect is small for patients with a small amount of OPRT (see Non-Patent Document 1). Therefore, for example, when treating tumor patients, measuring the amount of OPRT in the excised tumor in advance is an important indicator, such as determining the treatment method and selecting an anticancer drug to be administered. .
