  Presenilins and Wnt/β-catenin signalling Several groups have provided substantial data indicating that PS1 acts as a negative modulator of the transcriptional activity of the β-catenin/Tcf-4 complex (Fig. 4) [120], [121], [122]. β-Catenin is a multifunctional protein that was first described as a

  Until recently the mechanism of how GSMs shifted γ-secretase cleavage was poorly understood. Today, building on the sequential cleavage model developed by Ihara and colleagues [14], there is evidence that GSMs act as processivity enhancers, and iGSMs as inhibitors of processivity [120]. At least for

  FXR agonists represent an attractive class of drugs for patients with PFIC. Synthetic and semi-synthetic FXR agonists, with higher affinity and potency to activate FXR, have been successfully tested in animal models of cholestasis. In these murine models, the semi-synthetic steroidal FXR ligand obet

  2022-07-07

  

  The central event eliciting insulin secretion is the production of ATP which leads to the inhibition of ATP-sensitive inwardly-rectifying K+ATP channels, a consecutive depolarization of the plasma membrane with opening of voltage-dependent Ca2+ channels and Ca2+ influx into the beta-cell. However, i

  2022-07-06

  

  A second site of histone core domain acetylation that that has been observed on newly synthesized histones is histone H4 lysine 91 [34]. H4 lysine 91 lies along the interface between the H3/H4 tetramer and the H2A/H2B dimers. In fact, H4 lysine 91 normally forms a salt bridge with an aspartic Zalcit

  Treatment with histamine had no effect on histamine H1 receptor expression in HepG2 tropisetron synthesis (Fig. 1), while knockdown of histamine H1 receptor expression prevented histamine from repressing apo A-I gene expression (Fig. 2). Overexpression of the histamine H1 receptor regulated apo A-I

  A more quantitative view of kinase specificity suggests a continuum of phosphorylation rates for the various substrates of a particular kinase (Figure 4A). Such differences in ‘substrate quality’ can arise from variations in phosphorylation site or docking sequences and may explain why the timing or

  A nitric oxide donor, glyceryl-trinitrite, and the substrate for nitric oxide, l-arginine, have been used to treat preterm labor. However, these studies are preliminary. The beneficial effect of nitric oxide donors needs to be confirmed by more controlled studies. The probable pitfall of using nitri

  2022-07-06

  

  The opposite modulation observed for circulating LPI levels and WAT GPR55 327 2 by nutritional status suggests that increased levels of LPI may down-regulate the expression of its receptor in WAT, whereas in conditions of low serum LPI levels, the expression of GPR55 is stimulated. However, during

  We suggest that the FRET enhancement observed when the modified mD1 protein containing Acd at position 28 was excited at 260nm (), may differ from the diminution in fluorescence observed following excitation at 280nm due to the excitation of different transitions in Trp (i.e., the L and L transition

  Potential roles for S1P in angiogenesis, cancer, and autoimmune diseases such as RA have been reported [73]. In RA synoviocytes, S1P has been shown to enhance expression of prostaglandin E2 (PGE2) and cyclooxygenase-2 (COX-2) in response to the pro-inflammatory cytokines, TNF-α and interleukin (IL)-

  Sirolimus (rapamycin) and everolimus, both of which are mTOR inhibitors, are released by commonly used first- and second-generation DES. Considering the relatively high rates of the target vessel failure with currently available DES [12,14,16,45,46], there is a need for a novel drug strategy that pr

  Introduction Glycolysis plays a key role in AGK7 energy metabolism [[1], [2], [3]]. It is initiated mainly by hexokinase I (HKI), the major hexokinase isoform of the brain ([3,4] and references therein). Up to 90% of brain HKI is bound to the mitochondrial outer membrane (MOM) through the voltag
