  Human testicular peritubular 5 alpha reductase inhibitor (HTPCs) are also the only human testicular cell type that can be isolated, cultured and studied in vitro (Albrecht et al., 2006, Mayerhofer, 2013). Results from recent studies indicate that their roles go beyond sperm transport and include im

  Since forskolin is known to act directly at the catalytic site of adenylate cyclases near the ATP binding (Tesmer et al., 1997), the synergistic and/or permissive effect of gonadotropins on FSK activity must occur at the level of AC itself or very near, at the level of one of its direct partner. The

  Aberrantly enhanced adenosine signaling in retina of oxygen-induced retinopathy Current therapeutic development of ROP focuses on directly targeting VEGF and HIF-1α signaling pathway (Cavallaro et al., 2014, Penn et al., 2008, Mintz-Hittner et al., 2011, Hartnett and Penn, 2012).

  The α7 nAChR has been considered an interesting potential target for numerous therapeutic indications over the last two decades, with GTS-21 one of the first candidates proposed for Alzheimer's disease [2], [3], [23]. Unfortunately, although many α7-selective agonists have been developed [21], none

  Until now, five muscarinic receptor (M1-5) genes have been cloned, but, M1-3 receptors are functionally recognized in the lungs. Smooth muscle contraction is mainly mediated by M3. M2 may also participate in the contraction via Gi protein which leads to a decrease in cAMP. On the other hand, M2 is l

  Although effects of low concentrations of agonist were not as thoroughly documented for heteromeric receptors such as the major 3787 α4β2 nAChR, a similar mechanism of action was described to explain the potentiation of these receptors with low concentrations of acetylcholine-esterase-inhibiting dr

  Very recently, Niessen et al. have described the resensitizing effect of MB327 on nAChR performing solid-supported membrane (SSM)-based electrophysiological experiments (Niessen et al., 2016) using plasma membrane preparations obtained from Torpedo californica. These findings validated and underline

  ATM is required for the proper function of the DNA-repair pathway in response to bleomycin-induced DNA damage in mammalian cells [55], [56]. Recent reports suggest that ATM activation by double-strand breaks leads to the subsequent ATR activation [57], [58], [59]. The recruitment of ATR to double-st

  Besides Arg2 overexpression, our data revealed that AGEs could decrease eNOS mRNA levels, which is considered a significant cause for attenuated NO production and vasodilation. It was found recently that AGEs significantly reduce eNOS expression levels and NO bioavailability in human carotid artery

  Mitochondrial dysfunction resulting from mtDNA abnormalities may trigger retrograde signaling pathways from the mitochondrion to the nucleus, which regulate the expression of genes involved in diverse cellular processes, including metabolism, stress responses, tumor progression, nutrient sensing, li

  Consequences of central apelin/APJ modulation Regarding extra-hypothalamic actions, recent data demonstrate that the central apelin/APJ system could be a potential new target for the regulation of memory (Han et al., 2014). Then, intracerebroventricular (icv) apelin administration in mice impairs

  The putative 55-residue apelin proprotein (proapelin or apelin-55) is processed from a 77-residue preproprotein through removal of a 22-residue signal peptide (Table 1). Apelin-55 is further processed into bioactive isoforms of 36, 17, or 13 residues, likely through protease-mediated mechanisms. To

  There are several AP-1 Moxifloxacin receptor in the sequence of TIMP-1 promoter [18,19]. EBV could up-regulate TIMP-1 expression by binding to the AP-1 site in the TIMP-1 promoter [18]. IL-32, a newly multi-function cytokine, could activate AP-1, NF-κβ, p38MAPK signal pathways, and induce cytokine
