  Structure and function of EPAC isoforms EPACs are guanine nucleotide exchange factors (GEFs) for the Ras-like GTPases Rap1 and Rap2 [9]. There are two mammalian EPAC isoforms, EPAC1 and EPAC2 1, 2 (Figure 1). Whereas EPAC1 displays a wide tissue distribution, the expression of EPAC2 is more restr

  2021-08-20

  

  Since 1-OH-PGE2 is a moderately selective EP4 agonist which could bind to mouse EP3 and EP4 with a relatively similar affinity (Kiriyama et al., 1997), we have used a highly selective EP4 agonist CAY10580 to evaluate the involvement of EP4 activation in PGE2-facilitated EP4 internalization and recyc

  Introduction Hydrogen sulfide (H2S) and nitric oxide (NO) are important gasotransmitters in the cardiovascular system and instrumental to the fine control of vascular tone [1] and cellular function [2]. NO is synthesized from l-arginine by calmodulin-dependent endothelial nitric oxide synthase (e

  An important role for the precursor molecule of the main EBI2 ligand, 25-OHC, in the inhibition of inflammation was recently shown. 25-OHC was demonstrated to inhibit inflammasome induction in mouse macrophages [28]. Inflammasome assemblies are the sites of caspase 1 activation and lead to the gener

  The lack of effective strategies, aiming to directly increase the neuronal survival, is reflected by the fact that the only available therapeutic interventions are indirect. They consist of acute therapeutic interventions involving chemical and/or surgical removal of the thrombotic clot (Taqi et al.

  2021-08-19

  

  The first hint that GLP-1 might not be completely stable came from a meeting abstract in 1992, reporting that GLP-1 could be degraded in plasma incubations [16], although the enzyme(s) involved was not identified. A year later, Mentlein and colleagues [17], in a search for peptide substrates of the

  However, one major challenge will be to understand how the diverse actions of D2Rs in multipartite, dopamine-sensitive circuits are coordinated to produce specific behaviors across species. It is possible that emerging techniques for imaging neuronal activity in different neuronal population in beha

  Conclusions The PQQ-dependent CcPDH is the first PQQ-dependent enzyme identified in eukaryotes. The PQQ cofactor binds the enzyme with high affinity, reflected in a Kd of 1.1 nM, and the enzyme oxidizes 2KG, l-fucose, and rare sugars such as d-arabinose and l-galactose. The AA8 cytochrome b domai

  Cultured cells or mouse lung tissues were harvested and lysed in Radio-Immunoprecipitation Assay (RIPA) buffer (0.05 mol/l Tris–HCl pH 7.4, 0.15 mol/l NaCl, 0.25% deoxycholic acid, 1% NP-40, 1 mmol/l ethylenediamine tetraacetic y15 (EDTA), 1 mmol/l phenylmethylsulfonyl fuoride, 1 μg/ml aprotinin,

  The discoidin domain receptors, DDR1 and DDR2, are receptor tyrosine kinases (RTKs) that are stimulated by collagen in the extracellular matrix (ECM). Unlike most other RTKs, they form ligand-independent stable dimers that are non-covalently linked. This ECM activation induces receptor phosphorylati

  As previously stated, the most unexpected finding from this series of compounds was the identification of a dimethyl isoxazole side chain that gave dramatically improved binding over the parent compounds. Holding this piece of the molecule constant, a series of analogs were made to further understan

  Nucleophosmin (NPM1), which also plays a role on the nuclear export of ribosomal proteins and subunits (Maggi et al., 2008), is also a relevant MYC target, presumably through an interaction with CRM1. Conversely, it has been recently reported that specific SINE compounds reduce the levels of MYC in

  In the cytoplasm, the ternary CRM1–cargo–RanGTP complex is disassembled by the action of Ran-binding proteins RanBP1/2 and RanGAP. A recent kinetic study showed that the Ran-binding domains (RanBDs) of the cytoplasmic proteins RanBP1 and RanBP2, but not RanGAP, accelerate dissociation of NES from CR

  2021-08-18

  

  cAMP-mediated signaling pathways are important for maintaining metabolic homeostasis, and the effects of the glucagon/catecholamine–cAMP–PKA axis on energy balance have been well documented [20]. For example, Niflumic acid of the PKA 2β regulatory subunit (RIIβ) in mice leads to increased expressio
