  Main Text There are over 200 small GTPases that play critical roles in diverse fundamental cellular processes such as signal transduction, nmda receptor antagonist dynamics, and intracellular trafficking. Most of the GTPases act as switch-like molecules by cycling between the guanosine triphosphat

  Recent studies on detailed biochemical and structural characterization of plant GSNOR hedgehog inhibitor confirmed their similarities to mammalian homologues [16], [17], [18], [19]. Compared to human GSNOR, plant GSNORs exhibit differences in the composition of the anion-binding pocket, which negati

  2022-01-28

  

  The beta-catenin/TCF complex is an important target in the Wnt/beta-catenin pathway. This complex has proven challenging to target. However, natural inhibitors of this complex have been identified. One group of inhibitors is called the inhibitors of Wnt response (IWR-1/2). IWR-1/2 targets Axin and s

  Introduction Cell surface receptors are central to the interaction of cells with their surroundings and play an important role in determining functional responses. These receptors are integral membrane proteins responsible for the binding of extracellular signaling molecules and transduction into

  Introduction Herpes viruses are members of Herpesviridae family. This family consists of DNA viruses and it is a very large family. The viruses related to this family cause many diseases in animals and humans [1]. Herpes simplex viruses cause mucocutaneous lesions in the affected humans. These le

  The need for an ‘inflammatory risk profile’ was recently discussed by several investigators. The present study is all the more significant in that it shows that a phenomenon that is influenced by various atherosclerotic risk factors and acute phase proteins is, indeed, associated with a less favorab

  Unlike our present results in 4–12-week-old (~1–3 months) females, where a high-fat-diet-induced increase in body weight was evident, Schmidt et al. exposed male glut3 mice to a similar high-fat diet (60% kilocalories from fat) and observed no change in body weight, plasma glucose or insulin concent

  Methods Results and discussion Conclusions A third example of a hexokinase using polyphosphate exclusively as a phosphoryl donor has been identified, this time in mammalian tissues. This is the first polyphosphate utilizing enzyme activity demonstrated in mammalian O-propargyl-puromycin mg

  Recent research has focused on identifying key agonists and receptors mediating nutrient-induced GLP-1 and insulin secretion. The long-chain fatty GW441756 mg receptor GPR40 is the most abundant GPCR expressed in islet β cells and is also expressed on intestinal L-cells, where it contributes to GLP-

  Although it is well documented that FAAH substrates can elicit analgesic effects [for review see [47,48] and that systemic poly I:C administration induces mechanical allodynia in rats [14], to our knowledge this is the first study to demonstrate that enhancing FAAH substrate levels can modulate TLR3

  Introduction Currently, HIV-1 infection treatment guidelines adopted in USA and EU provide for the simultaneous administration of three antiretroviral drugs (HAART “Highly Active Anti-Retroviral Therapy”) in severely compromised patients [[1], [2], [3]]. Coupling at least two different mechanisms

  Introduction Hedgehog (HH) signaling regulates development, cell proliferation, and tissue repair [1], [2], [3]. In mammals, HH signaling is activated by 3 ligands: Sonic hedgehog (SHH), Indian hedgehog (IHH), or Desert hedgehog; SHH is the most widely expressed in adult tissues [3]. The primary re

  Introduction Epigenetic mechanisms modulate heritable phenotypic changes that are not dictated by changes in DNA sequences. The link between epigenetic modifications and cancer development has been established [1], [2]. Histone modifications represent an important class of epigenetic mechanisms tha

  The relaxant response to carperitide was influenced neither by the removal of the endothelium nor by treatment with the nitric oxide synthase inhibitor or nitric oxide scavenger. This result was to be expected as previous studies showing that the vasodilator action of atrial natriuretic peptide is e
