Induction of cytochrome P4501A1.
Cytochrome P4501A1 is a substrate-inducible microsomal enzyme that oxygenates polycyclic aromatic hydrocarbons, such as the carcinogen benzo(a)pyrene, as the initial step in their metabolic processing to water-soluble derivatives. Enzyme induction reflects increased transcription of the cognate CYP1A1 gene. The environmental toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin is the most potent known ...
متن کاملFrequency of CYP1A1 Gene Polymorphisms in Infertile Men with Non-obstructive Azoospermia
Background and Aims: The cytochrome P450 1A1 (CYP1A1) plays a curial role in phase I metabolism of polycyclic aromatic hydrocarbons to their ultimate biologically active intermediates that have potential reproductive toxicity in men. Reproductive functions in men may be impaired by many environmental, physiologic, and genetic factors. The majority of the environmental factors are xenobiotics. M...

متن کاملAnalysis of PRM1 and PRM2 Polymorphisms in Iranian Infertile Men with Idiopathic Teratozoospermia
Abstract Background: Single nucleotide polymorphisms (SNPs) in some genes which are involving in sperm maturation, are considered as one of the main reason for male infertility. Any changes in protamine genes may cause abnormal histone-protamine replacement during spermiogenesis and have been indicated to cause sperm DNA damage and infertility. Objective: The aim of present case-control study w...
متن کاملIncreased risk of testicular germ cell cancer among infertile men.
BACKGROUND The risk of testicular cancer is thought to be higher among men seeking infertility treatment compared with the general population. Confirmation of this risk in a large US cohort of at-risk patients is lacking. This study explored the association between male infertility and subsequent development of testicular cancer in a US-based cohort. METHODS A total of 51 461 couples evaluate...
