PURPOSE To evaluate the prevalence and the diagnostic utility of testing for CYP1B1 copy number variation (CNV) in primary congenital glaucoma (PCG) cases unexplained by CYP1B1 point mutations in The Australian and New Zealand Registry of Advanced Glaucoma. METHODS In total, 50 PCG cases either heterozygous for disease-causing variants or with no CYP1B1 sequence variants were included in the ...
Estrogen production and metabolism play critical roles in the development and pathogenesis of endometrial carcinoma. Cytochrome P450 1B1 (CYP1B1) and catechol-O-methyltransferase (COMT) are two key enzymes in the estrogen metabolism pathway that result in the hydroxylation and conjugation of estradiol, respectively. We evaluated the association between the CYP1B1 Leu432Val and CYP1B1 Asn453Ser ...
Cytochrome P4501B1 (CYP1B1) is the most recently identified member of the dioxin-inducible CYP1 family. CYP1B1 is constitutively expressed in most human tissues, including colon and breast, and can activate numerous chemically diverse carcinogens. We evaluated the metabolism of the dietary heterocyclic amine carcinogen 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) by microsomes from ye...
The shared tumor-associated antigen cytochrome P450 1B1 is recognized by specific cytotoxic T cells.
Cytochrome P450 1B1 (CYP1B1), a drug-metabolizing extrahepatic enzyme, was recently shown to be overexpressed in multiple types of cancer. Such tumor-associated genes may be useful targets for anticancer therapy, particularly cancer immunotherapeutics. We identified HLA-A*0201-binding peptides and a naturally processed and presented T-cell epitope capable of inducing CYP1B1-specific cytotoxic T...
PURPOSE To examine the effects of genetic polymorphisms in cytochrome P450, subfamily 1, polypeptide 1 (C1P1B1) on primary open-angle glaucoma (POAG). METHODS A systematic literature search was performed, and random-effects meta-analyses were used to evaluate genetic polymorphisms in CYP1B1 with POAG. A gene-based analysis was conducted to investigate the cumulative effects of genetic polymor...
The Cytochrome P-4501B1 (CYP1B1) Leu432Val polymorphism has been previously shown to be associated with some types of cancer and affects CYP1B1-mediated metabolism of various infertility drugs. To establish the frequency of CYP1B1 Leu432Val polymorphism among women with a history of infertility drug use, we studied the genotypes of 147 patients with breast cancer with a history of infertility a...
Humans are exposed to polycyclic aromatic hydrocarbons (PAHs) through many environmental pollutants, especially cigarette smoke. These chemicals cause a variety of tumors and immunotoxic effects, as a consequence of bioactivation by P-450 cytochromes to dihydrodiol epoxides. The recently identified cytochrome P4501B1 (CYP1B1) bioactivates PAHs but is also a physiological regulator, as evidenced...
Oral Squamous Cell Carcinoma (OSCC) has a very flagitious treatment regime. A prodrug approach is thought to aid in targeting chemotherapy. CYP1B1, a member of cytochrome P450 family, has been implicated in chemical carcinogenesis. There exists a general accordance that this protein is overexpressed in a variety of cancers, making it an ideal candidate for a prodrug therapy. The activation of t...
AIMS CYP1A1 and CYP1B1, members of the cytochrome P450 protein family, are regulated by fluid shear stress. This study describes the effects of duration, magnitude and pattern of shear stress on CYP1A1 and CYP1B1 expressions in human endothelial cells, towards the goal of understanding the role(s) of these genes in pro-atherogenic or anti-atherogenic endothelial cell functions. METHODS AND RE...
Prostate cancer (PCa) is the most common non-skin cancer and the second leading cause of cancer death among men in the world. Growth, maintenance and the expression of genes involved in the production of steroids, may alter the susceptibility of prostate cancer. One such gene, CYP1B1 (cytochrome P450, family 1, subfamily B, polypeptide 1) is involved in the activation of many carcinogens and i...
