Pregnane X receptor (PXR) is a nuclear receptor that regulates the expression of genes for cytochrome P450 3A (CYP3A), multidrug resistance 1 (MDR1), and organic anion-transporting peptide 2 (OATP2). These genes control the metabolism (CYP3A subfamily) and aspects of the pharmacokinetics (MDR1 and OATP2) of both endogenous and xenobiotic compounds. Since PXR is important in understanding the ac...

Along with other etiological factors like genetics, family history, age, etc. there is growing scientific evidence that exposure to chemicals, including pesticides is associated with increased incidence of breast cancer among women. Various animal studies have demonstrated the carcinogenic effect of pesticides byacting as Xenoestrogen, interacting and disrupting estrogen receptors or by damagin...

DNA methylation and histone modifications have essential roles in remodeling chromatin structure of genes necessary for multi-lineage differentiation of mammary stem/progenitor cells. The role of this well-defined epigenetic programming is to heritably maintain transcriptional plasticity of these loci over multiple cell divisions in the differentiated progeny. Epigenetic events can be deregulat...

Background: Human epidermal growth factor receptor 2 (Her2) gene located in human chromosome17, encodes Her2 tyrosine kinase protein, and is overexpressed breast cancer cells. activated on phosphorylation of by adenosine triphosphate (ATP). Nonetheless, excessively partakes the development prognosis specific types aggressive cancers. Therefore, inhibition therapy primary target for treatment ca...

The aim of the study was to explore whether G-Protein-Coupled Receptor 30 (GPR30) was expressed in rat testicular Sertoli cells and to assess the impact of monobutyl phthalate (MBP) on the expression of GPR30 in Sertoli cells. By using RT-PCR, Western-Blot and immunofluorescent microscopy, the expression of GPR30 in rat Sertoli cells was found at both gene and protein level. Cultures of Sertoli...

Aims of the study: Endometriosis is a prevalent gynecologic disorder in young women at reproductiveage but the underlying risk factors have not identified yet in Iran and other neighboringcountries. Persistent exposure to environmental endocrine disrupting chemicals (EDCs) in particulardioxins, PAHs and polychlorinated biphenyls (PCBs) with xenoestrogenic potentials have beenhypothesized in the...
