The effects of altered estrogenic environments on creatine kinase (CK) and adenylate kinase (AK) were studied in two rodent mammary tumor systems, R3230AC and primary 7,12-dimethylbenz(a)anthracene iDMB \) indim-d carcinomas, to determine whether response of these enzymes could be related to their hormone dependence. The hormonal perturbations studied were ovariectomy and administration of vari...

BACKGROUND Azoospermia is the medical condition of a man not having any measurable level of sperm in his semen. Follicle stimulating hormone (FSH) is a member of the glycoprotein hormone family that plays an important role in human reproduction because of its essential role in normal spermatogenesis. Various Single Nucleotide Polymorphisms (SNPs) have been reported within FSH receptor (FSHR) ge...

Glycoprotein hormone receptors (GPHR) have a large extracellular domain (ECD) divided into the leucine rich repeat (LRR) domain for binding of the glycoprotein hormones and the hinge region (HinR), which connects the LRR domain with the transmembrane domain (TMD). Understanding of the activation mechanism of GPHRs is hindered by the unknown interaction of the ECD with the TMD and the structural...

background: breast cancer is the most common cancer in women worldwide. recently, natural remedies such as naringenin (nar) - a kind of flavonoids which can be found in grapefruits, oranges, and tomatoes - seem to be interesting. they play a useful role in treatment and chemoprevention because of having pleiotropic molecular mechanisms of action on breast cancer cells. methods: we performed a p...
