Cytochrome P450s (P450s) comprise a gene superfamily encoding enzymes that are involved in diverse plant metabolic pathways that produce primary and secondary metabolites such as phenylpropanoids, terpenoids, nitrogen-containing compounds, and plant hormones. They comprise one of the most diverse gene families in plant evolution.

CYP2E1 PstI polymorphism increases cervical neoplasia risk: a meta-analysis

X. Wang and He, Y., “CYP2E1 PstI polymorphism increases cervical neoplasia risk: a meta-analysis”, vol. 14, pp. 5203-5209, 2015.

Cytochrome P4502E1 (CYP2E1) is a key enzyme in the metabolic activation of many carcinogens, but the roles of CYP2E1 polymorphisms in cervical neoplasia (CN) are inconclusive. Published case-control cohort studies from the Pubmed, Embase, and China National Knowledge Infrastructure databases were retrieved. Data were extracted and pooled odds ratios with 95% confidence intervals were calculated. Seven studies examining 1097 cases and 1117 controls were included in this meta-analysis.

Molecular cloning and cDNA characterization of Camelus dromedarius putative cytochrome P450s 1A, 2C, and 3A

H. M. Saeed, Alanazi, M. S., Shalaby, M. A., Alshahrani, O., Ataya, F. S., Pathan, A. A., and Abduljaleel, Z. A., “Molecular cloning and cDNA characterization of Camelus dromedarius putative cytochrome P450s 1A, 2C, and 3A”, vol. 13, pp. 2886-2905, 2014.

The domesticated one-humped Arabian camel, Camelus dromedarius, is one of the most important animals in the Arabian Peninsula. Most of its life, this animal is exposed to both intrinsic and extrinsic genotoxic factors that are known to cause gross metabolic alterations in many organisms. This study determined the full length coding sequence of 3 cytochrome P450s cDNAs; namely, CYP450 1A1, CYP450 2C and CYP450 3A using reverse transcription polymerase chain reaction. The C.

Prevalence of CYP2C8 polymorphisms in a North Indian population

S. Minhas, Setia, N., Pandita, S., Saxena, R., Verma, I. C., and Aggarwal, S., “Prevalence of CYP2C8 polymorphisms in a North Indian population”, vol. 12, pp. 2260-2266, 2013.

CYP2C8 is an important member of the cytochrome P450 family of enzymes; it affects the activity of various drugs used in routine clinical practice, including amiodarone, chloroquine, amodiaquine, and repaglinide, as well as endogenous compounds, such as arachidonic acid and retonic acid. It is also the main enzyme involved in the metabolism of the widely used anticancer drug Paclitaxel, which has a very narrow therapeutic index.

Interaction between CYP 2C19*3 polymorphism and smoking in relation to laryngeal carcinoma in the Chinese Han population

J. Feng, Li, L., Zhao, Y. - S., Tang, S. - Q., Yang, H. - B., and Liu, S. - X., “Interaction between CYP 2C19*3 polymorphism and smoking in relation to laryngeal carcinoma in the Chinese Han population”, vol. 10, pp. 3331-3337, 2011.

Cytochrome P450 (CYP) 2C19 metabolizes arachidonic acid to biologically active epoxyeicosatrienoic acids, which strongly promote proliferation of cancer cells in vitro and in vivo. Knowing that smoking is the most important risk factor for laryngeal carcinoma, we examined the relationships between CYP2C19*3 polymorphism, smoking and laryngeal carcinoma in the Chinese Han population. In a Chinese Han case-control study of 300 laryngeal carcinoma patients and 300 healthy controls, we investigated polymorphism in the CYP2C19 gene by PCR-RFLP analysis.
