  2023-05-15

  

  In addition to pH regulation by ion (counter-) fluxes, acidification is regulated by the abundance of V-ATPase on organelles, by the pumping activity of the complex and by proton leakage. In yeast, the V-ATPase VO subunit a is the only subunit expressed in two isoforms termed Stv1p and Vph1p. V-ATPa

  2023-05-15

  

  In our studies of leucine and BCH in pancreatic islets and clonal insulin cell lines, we noticed that leucine was a slightly stronger stimulant of insulin release. Previous studies showed that leucine can be metabolized to CO2[11], [12], [13], [14] and can increase acetoacetate in pancreatic islets

  2023-05-15

  

  The 15-LOX hydroxide metabolites are converted to secondary lipid mediators such as lipoxin A4 from 15-HETE and protectin D1/resolvin D1 from 17-HDoHE [45] (Fig. S3). Importantly, all of these secondary lipid mediators have anti-inflammatory and pro-resolving properties [46], [47], [48]. Lipoxin A4

  2023-05-15

  

  There is limited information regarding hyperargininemia incidence or prevalence. Reports of incidence vary by an order of magnitude: 0.5 to 5.0 per million [5], [6]. A relatively large U.S. study estimated 1.1 cases per million births [7], but it used an indirect methodology that introduces uncertai

  2023-05-15

  

  It is now thought that tight binding of HMGB to condensed chromatin may not be restricted to apoptotic cells. That HMGB proteins might actually be involved in the organization and/or maintenance of heterochromatic regions is suggested by the results of experiments analyzing the stable binding of the

  2023-05-15

  

  Echinocandin resistance is systematically associated with point mutations in either FSK1 or FSK2 genes [7], [104]. These mutations are located in two different not spot regions of these genes named HS1 and HS2. Hot spot mutations have been reported in C. albicans, C. glabrata, C. tropicalis, C. krus

  Concluding Remarks Despite major advances in the development of antibody and small-molecule tumor angiogenesis inhibitors, therapy resistance, both innate and acquired, continues to limit further survival improvements for patients with cancer. Preclinical models of localized primary tumors and me

  2023-05-15

  

  VEGFR2 inhibition using sunitinib does not result in tumor growth reduction or in a further decrease in vessel density in NDRG1 overexpressing glioma rendering these tumors intrinsically resistant to antiangiogenic treatment. Intrinsic resistance to antiangiogenic therapy is defined as a non-respons

  2023-05-15

  

  It has been proposed that angiotensin II (Ang II) may upregulate COX-2 expression and the subsequent vasoconstrictor prostanoids production through the activation of AT-1 receptors in vascular smooth muscle cells (Hu et al., 2002). Additionally, this peptide is also able to stimulate the generation

  2023-05-15

  

  Atypically, BcALDH has a minor reducing activity for all-trans-retinal, which requires the binding of the reduced form of the NADP+ (NADPH) cofactor that is a side-product of the canonical oxidation activity of BcALDH. The reduction activity that converts all-trans-retinal to all-trans-retinol was r

  Whether similar mechanisms play a role in adiponectin signal transduction and whether additional proteins are recruited to adiponectin receptors via APPL1 has not been analysed so far. Although it has been clearly established that APPL1 is a downstream adaptor protein in adiponectin signal transduct

  Adenosine is a ubiquitous homeostatic substance released from most cells, including neurons and glias. Endogenous adenosine acts at four principal G-protein-associated receptor subtypes: A1, A2a, A2b and A3 (Ralevic and Burnstock, 1998). The stimulation of adenosine receptors by extracellular adenos

  Introduction Cancer, which is responsible for a million deaths each year, is universally feared, and approximately 50% of newly diagnosed cases can be cured [1]. The existing cancer treatments, including surgery, chemotherapy, radiotherapy or a combination of them, are quickly losing efficacy. The

  Autophagy and cell death pathways in ischemic stroke Although very important for the effects on post-ischemic LY2109761 injury, autophagy is not the only mechanism of action involved in cell death. Necrosis and apoptosis are two other distinct forms of cell death with great difference in morphol

  If the lack of specificity and the high pleiotropy may represent a problem in view of the potential chemotherapeutic features of autophagy-inducing agents, it monobenzone may switch into an advantage in the case of chemopreventive strategies. In fact, as non-pharmacologic interventions such as limi
