PMID: 26557919
Thorac Cancer. 2015 Nov;6(6):785-91. doi: 10.1111/1759-7714.12303. Epub 2015 Aug 20.

BACKGROUND: This study evaluated the efficacy and safety of irinotecan/cisplatin (IP) and etoposide/cisplatin (EP) in extensive-stage small cell lung cancer (ES-SCLC) and the distribution of uridine diphosphate glucuronosyltransferase (UGT1A1). The relationship between UGT1A1 genotypes and patient outcomes was also...

Case Rep Oncol Med. 2017;2017:2683478. doi: 10.1155/2017/2683478. Epub 2017 Sep 26.

Alveolar rhabdomyosarcoma (AR) in adult patients is an exceptional malignancy. Management of AR is based on (neo)adjuvant chemotherapy combining ifosfamide, vincristine, and actinomycin D and local curative-intent surgery/radiotherapy. In cases of relapsing AR, the combination of temozolomide/irinotecan is regarded...

Pharmacol Res Perspect. 2014 Oct;2(5):e00053. doi: 10.1002/prp2.53. Epub 2014 Jul 02.

Cytochrome P450 (CYP) 3A4 is a membrane protein that catalyzes hydroxylation of endogenous and exogenous substrates. Protein-protein interaction is a crucial factor that regulates the function of enzymes. However, protein-protein interactions involving human CYPs have not been fully understood....

Bavachalcone and corylin are two major bioactive compounds isolated from Psoralea corylifolia L., which has been widely used as traditional Chinese medicine for many years. As two antibiotic or anticancer drugs, bavachalcone and corylin are used in combination with...

Update on the Genetic Polymorphisms of Drug-Metabolizing Enzymes in Antiepileptic Drug Therapy.

Pharmaceuticals (Basel, Switzerland)

Saruwatari J, Ishitsu T, Nakagawa K.
PMID: 27713373
Pharmaceuticals (Basel). 2010 Aug 20;3(8):2709-2732. doi: 10.3390/ph3082709.

Genetic polymorphisms in the genes that encode drug-metabolizing enzymes are implicated in the inter-individual variability in the pharmacokinetics and pharmaco-dynamics of antiepileptic drugs (AEDs). However, the clinical impact of these polymorphisms on AED therapy still remains controversial. The defective...

Effect of MRP2 and MRP3 Polymorphisms on Anastrozole Glucuronidation and MRP2 and MRP3 Gene Expression in Normal Liver Samples.

International journal of cancer research and molecular mechanisms

Edavana VK, Penney RB, Yao-Borengasser A, Starlard-Davenport A, Dhakal IB, Kadlubar S.

Int J Cancer Res Mol Mech. 2015 Oct;1(3). doi: 10.16966/2381-3318.112. Epub 2015 Sep 22.

Anastrozole is an aromatase inhibitor (AI) used as adjuvant therapy for breast cancer. Anastrozole is subject to direct glucuronidation catalyzed by UDP-glucuronosyltransferase1A4 (UGT1A4). Interindividual variability in anastrozole glucuronidation may be affected by UGT1A4 SNPs. Interplay between drug metabolizing genes...

Hydroxylation and sulfation of sex steroid hormones in inflammatory liver.

Journal of biomedical research

J Biomed Res. 2017 Sep 26;31(5):437-444. doi: 10.7555/JBR.31.20170031.

Sex steroids, also known as gonadal steroids, are oxidized with hydroxylation by cytochrome P450, glucuronidation by UDP-glucuronosyltransferase, sulfation by sulfotransferase, andO-methylation by catechol O-methyltransferase. Thus, it is important to determine the process by which inflammation influences metabolism of gonadal...
