PRINCIPLES Associations between polymorphisms for genes encoding enzymes involved in biotransformation of xenobiotics and susceptibility to several cancers have been shown in several studies. The aim of the present study is to investigate the influence of cytochromes P450 (CYP450) 1A1*2C and Glutathione S-transferases (GSTs) (T1 and M1) gene polymorphisms(More)
OBJECTIVE To examine whether a relationship exists between genetic polymorphisms of glutathione S-transferase (GST) M1 and T1, CYP1A1(*)2C, and male factor infertility. DESIGN Genetic polymorphism analysis, case-control study. SETTING University research laboratory and andrology clinic. PATIENT(S) One hundred ten men with infertility and 105 healthy(More)
Carcinogenic and toxic molecules produce DNA adducts that contribute to the development of atherosclerosis. Genetic polymorphisms of xenobiotic-detoxified enzymes, which control the level of DNA adducts, may affect both enzymatic activity and individual susceptibility to coronary artery disease (CAD). In this study we investigated the effects of genetic(More)
The mechanism of final cessation of the reproductive life span has not been solved yet. It is generally assumed that the most important factor is ovarian follicular reserve. In ovaries at intrauterine period, a major factor that determines the number of the primordial follicle is the mitotic ability as well as the number of primordial germ cells, which(More)
OBJECTIVE To analyze an unusual nonrobertsonian translocation t(9;15)(p10;q10) found in an infertile man with oligoasthenoteratozoospermia who had a normal phenotype. DESIGN Case report with a review of scientific literature. SETTING Academic research environment. PATIENT(S) Infertile man with oligoasthenoteratozoospermia but otherwise apparently(More)
Death-associated protein kinase-1 (DAPK1) is a pro-apoptotic gene that induces cellular apoptosis in response to internal and external apoptotic stimulants. The silencing of DAPK1 can result in uncontrolled cell proliferation, indicating that it may have a role in tumor suppression. DAPK1 activity can be inhibited by the cytosine methylation that occurs in(More)
This study was conducted to determine the effects of methionine, inositol and carnitine on sperm (motility, abnormality, DNA integrity and in vivo fertility) and oxidative stress parameters (lipid peroxidation, total glutathione and antioxidant potential levels) of bovine semen after the freeze-thawing process. Nine ejaculates, collected with the aid of an(More)
Infertility affects 1 in 6 couples and approximately 1 in 25 men. Male factor infertility is a major cause of spermatogenic anomalies, the causes of which are largely unknown. Impaired repro-ductive functions in men might result from physiological, genetic, and/or environmental factors such as xenobiotics. The multi-drug re-sistance1 (MDR1) gene encodes a(More)
