Calcium ions (Ca(2+) ) act as second messengers in intracellular signaling. Ca(2+) pumps, channels, sensors, and calcium binding proteins, regulate the concentrations of intracellular Ca(2+) as a key regulator of important cellular processes such as gene expression, proliferation, differentiation, DNA repair, apoptosis, metastasis, and hormone secretion. Intracellular Ca(2+) also influences the functions of several organelles, that include: the endoplasmic reticulum, mitochondria, the Golgi, and cell membrane both in normal and breast cancer cells...

Follicle stimulating hormone (FSH) is released from the anterior pituitary gland and has an important role in female fertility. As FSH is a glycoprotein polypeptide hormone which cannot pass through the cell membrane, its influence on target cells must be mediated by the FSH receptor (FSHR). Accordingly, any kind of mutation in FSHR can affect reproduction in dairy cows. In this study, the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used for recognition of a point mutation (A/G: position -278) located in the FSHR gene in Iranian dairy cows...

Non-communicable diseases (NCDs) account for 76% of deaths in Iran and this number is on the rise, parallel to global rates. Many risk factors associated with NCDs are preventable; however it is first necessary to conduct observational studies to identify relevant risk factors, and the most appropriate approach to control them. Iran is a multi-ethnic country, therefore the Ministry of Health and Medical Education sought to launch a nationwide cohort study-the Prospective Epidemiological Research Studies in IrAN (PERSIAN)-in order to identify the most prevalent NCDs among Iranian ethnicities, and to investigate effective methods of prevention...

Exercise training can affect the breast tumor growth. We hypothesized that exercise training may reduce breast tumor growth by inducing Oxytocin (OT) secretion and its related signaling pathways such as PI3K/AKT and ERK. Therefore fifty-six BALB/c mice were equally divided into seven groups to study the effects of OT and atosiban (an oxytocin receptor antagonist) together with the interval exercise training on breast tumor growth, as well as tumor related signaling pathways including PI3K/AKT and ERK. Animal weight, OT plasma level, tumor weight and volume measured at the end of study...

BACKGROUND: Male factor infertility has increased to more than 40% during the last decade. About 30% of these couples are diagnosed with unexplained infertility. In fact, reactive oxygen species (ROS), especially superoxide anion (O2(-)·) and hydrogen peroxide (H2O2), play a crucial role in regulation of physiological and pathological processes in spermatozoa. Moreover, since the diagnosis of unexplained infertility just through semen analysis is a matter of much controversy; we aimed to evaluate the levels of ROS and sperm DNA fragmentation in the semen samples of unexplained infertile and fertile control couples...
