uridine diphosphate/neoplasms

Uridine diphosphate (UDP) reductase was isolated in the supernatant fraction obtained after the acidification of the cytosol of Ehrlich ascites tumor cells, and was found insensitive to 10 mM hydroxyurea. However, cytidine diphosphate (CDP) reductase, being separated concurrently in the precipitate

OBJECTIVE The aim was to investigate the association between uridine diphosphate glucuronide transferase 1A1 (UGT1A1) gene promoter region polymorphism and irinotecan-related adverse effects and efficacy on recurrent and refractory small cell lung cancer (SCLC). METHODS A total of 31 patients with

OBJECTIVE To investigate the association of variations in the cyclooxygenase-2 (COX2) and uridine diphosphate glucuronosyltransferase 1A6 (UGT1A6) genes and non-steroidal anti-inflammatory drugs (NSAIDs) use with risk of colon cancer. METHODS NSAIDs, which are known to reduce the risk of colon

OBJECTIVE Inherited variations in drug metabolizing enzymes may influence drug efficacy. This phase II study assesses the impact of second-line weekly irinotecan (CPT-11)/docetaxel in non-small cell lung cancer (NSCLC) patients, and gauges the uridine diphosphate glucuronosyl transferase (UGT1A1)

Our study investigated the effects of the chemopreventive agent sulforaphane (SFN) on human colon cancer Caco-2 cells and potential underlying mechanisms of the effects. When treated with SFN at hypotoxic levels, UDP-glucuronosyltransferase 1A (UGT1A) was induced in a dose-dependent manner. SFN at

The goal of chemotherapy is the elimination of tumor cells from the host. This is achieved by the use of therapeutic agents that are often more harmful to normal tissues than to the targeted tumor. Many chemotherapeutic agents are designed to damage cell replication machinery either directly at the

The concentration of phosphates and the kinetics of phosphate transfer reactions were measured in the human breast cancer cell line, T47D, using 31P-NMR spectroscopy. The cells were embedded in agarose filaments and perifused with oxygenated medium during the NMR measurements. The following

Here we report a case of metastatic colon cancer treated with 5-fluorouracil, leucovorin, and escalated doses of irinotecan (FOLFIRI) combined with regorafenib in the fourth-line setting after uridine diphosphate glucuronosyltransferase (UGT)1A1 genotyping analysis. A 66-year-old male was initially

OBJECTIVE Variant genotypes of uridine diphosphate glucuronsyltransferase isoenzyme 1A6 (UGT1A6) associated with decreased metabolic activity have been associated with an enhanced protective effect of aspirin on the development of colorectal adenomas. However, interactions between UGT1A6 variants or

Colorectal cancer (CRC) is a leading cause of cancer death in the United States. In recent years, therapeutic advances have prolonged the survival of patients with advanced disease. Along with the addition of new treatments, an increasing body of literature explores the potential benefit of using

The genetic backgrounds of the Japanese (or Asians) are, at least in part, different from those of Caucasians. It is necessary to recognize this difference to develop medicine that is both optimized and individualized. In particular, the consideration of ethnic differences is becoming increasingly

BACKGROUND Metastatic colorectal cancer (mCRC) imposes a substantial health burden on individual patients and society. Furthermore, rising costs in oncology cause a growing concern about reimbursement for innovations in this sector. The promise of pharmacogenomic profiling and related stratified

BACKGROUND In the current Phase II study, the authors evaluated the association between genomic polymorphic variants in uridine diphosphate glucuronosyl transferase (UGT1A1), methylenetetrahydrofolate reductase (MTHFR), and thymidylate synthase (TS) genes, and the incidence of the adverse effects of
