  2021-12-30

  

  Regulation of pancreatic α and β cell mass has been extensively studied and hotly debated, due to potential therapeutic implications. Early claims of Angptl8 as “betatrophin” and Angptl4 as a regulator of glucagon secretion and α cell proliferation (Yi et al., 2013, Ben-Zvi et al., 2015) have not st

  2021-12-30

  

  Gap junction channels exhibit different types of gating properties. One alternative mechanism that should be mentioned is loop gating in which the extracellular loop of connexin assumes a configuration to form a narrow pathway for closure of unopposed hemichannels [53] and docked junction channels [

  2021-12-29

  

  How changes in APP processing by γ-secretase lead to AD is still not well understood. Deposition of amyloid beta (Aβ) peptide fragments of the amyloid precursor protein (APP) in amyloid plaques and hyperphosphorylated tau in neurofibrillary tangles are the cellular hallmarks of AD (O’Brien and Wong,

  By association, a possible mechanism which may underlie the progression of seizures is long-term potentiation (LTP). Indeed, LTP shares many common mechanisms with seizures activity both anatomically and physiologically, and has been implicated as a mechanism of acute epileptogenesis (Wasterlain et

• The membrane metalloendopeptidase MME gene

  2021-12-29

  

  The membrane metalloendopeptidase (MME) gene is located at human chromosome 3q21-27. It encodes a 100-kD type II transmembrane glycoprotein, a widely expressed membrane metalloendopeptidase that degrades a number of substrates. The active site of the enzyme faces the extracellular space. MME is wide

  It should be noted that the current studies were performed in female rats. Although the oestrous cycle has been shown to modulate inflammatory processes in the periphery, data from our group has demonstrated that the phase of the oestrus cycle does not significantly alter TLR3-mediated neuroinflamma

  We also intended to determine the possible mechanism underlying EZH2 upregulation in the PC. Although no recurrent mutations of EZH2 have been described in CLL [27, 28, 29], we aimed to rule out the possibility of activating mutations in the background of EZH2 overexpression. We detected no mutation

  Methods Results Discussion SV exocytosis from excitatory boutons is more sensitive to inhibition by isoflurane than exocytosis from inhibitory boutons,4, 31 but the mechanism(s) of this synaptic selectivity is unknown. Although P/Q-type VGCCs contributed quantitatively more to SV exocytosis t

  This connection is supported by studies in the SIV macaque model of HIV, where treatment with methamphetamine, which greatly enhances CNS dopamine levels (Truong, 2005); increased aminopyridine viral load. Methamphetamine also increased expression of the HIV co-receptor CCR5 in CNS macrophages, the

  2021-12-29

  

  The increased levels of proinflammatory cytokines in BALF are noted during ALI/ARDS, and the persistent elevation of these mediators may exaggerate systemic or focal inflammatory reaction with a worse outcome. These cytokines, particularly TNF-α and IL-6, play essential roles in ALI [16,17]. The ov

  2021-12-29

  

  The role of the cyclic AMP regulated exchange factor Epac1 is emerging in cancer (Almahariq et al., 2015, Banerjee and Cheng, 2015, Parnell et al., 2015, Parnell et al., 2015, Schmidt et al., 2013). Interestingly, in cancer cell migration, activation of Epac1 can be linked to activation of Rac. As s

  2021-12-29

  

  The action of niacin in upregulating cAMP is most likely determined by the milieu of adenylyl cyclase isoforms expressed in macrophages that are responsive to GPR109A activation. Several adenylyl cyclase isoforms, namely AC2, AC4 and AC7, are responsive to the stimulatory action of Gβγ G-protein sub

  To test this concept, we took advantage of our large supply of various 2-pyridyl containing [3.1.0] cores (inactive with alkyl or aryl sulfonamides) and prepared the -methylimidazole sulfonamide analogs and (), as work form Merck demonstrated that the 2-pyridyl moiety was superior to the original

  The HH-Gli pathway has been demonstrated to play an extensive role in skeletal development. India Hedgehog, derived from hypertrophic chondrocytes, and Parathyroid Hormone-like related Protein (PTHrP), derived from peri-articular chondrocytes, form a negative feedback loop to inhibit chondrocyte hyp

  The diverse biochemistry of zinc means that, in many cases, more than one factor (or pathway) is at play. Whilst catalytic Zn2+ sites are now typically well-understood, the recognition that Zn2+ levels regulate the function of many cell types has led to vigorous interest in the fate and role of mobi
