  Breast cancer The interactions between 15-LOX and COX enzymes also affect the outcome of breast cancer. Indomethacin, a COX-1 and COX-2 inhibitor, decreased the growth of human breast cancer (BC) cells in nude mice, as well as slowed the rate of lung metastasis formation [41]. The levels of 12-HE

  Thus, a majority of known chemical and physico-chemical methods of metallic ions assay has a number of disadvantages, such as a low sensitivity and selectivity, high costs and complexity of the equipment. Therefore, the development of simple cost-effective sensitive methods of quantitative analysis

  Introduction Active oxygen radicals in the human body have a strong effect of inducing lipid peroxidation, which in turn induces oxidative imbalance and causes various diseases. Natural polysaccharides are substances with certain antioxidant activity. They are used as antioxidants and have advant

  A selected set of these new derivatives was then used for functional assays at the human A1AR showing, as expected, an antagonist profile with IC50 values at nanomolar level. The same molecules showed also to be efficacious as nanomolar antagonists in a functional assay aimed at analyzing their abil

  It has been recognized for decades that neurons in the mammalian central nervous system may release both a fast-acting, typically amino acid derived neurotransmitter such as glutamate or GABA, and a second peptidergic neuromodulatory molecule such as neuropeptide Y, substance P, or cholecystokinin.

  The known crystal structures of class C GPCR VFTs do not include attached TM domains, therefore current conformational data may not accurately reflect the dynamics of extracellular domains in full-length receptors. Nevertheless, compelling mechanisms of signal transduction can still be postulated. S

  Cell surface metalloproteases coordinate signaling during development, tissue homeostasis, and disease. A disintegrin and metalloprotease 17 (ADAM17) is a well-characterized member among ADAM family, which mediates the cleavage of various cell surface proteins (Black, 2002, Black et al., 1997, Dello

  In conclusion, this study detected the expression of adiponectin and its receptors, AdipoR1 and AdipoR2, in goat ovarian follicles. In addition, adiponectin was shown to enhance the progression of goat oocyte nuclear maturation in vitro. The present findings provide evidence for paracrine/autocrine
