  2022-05-04

  

  Nicastrin is heavily glycosylated, contributing 40–70KDa to the molecular weight of human γ-secretase. Among the 16 predicted N-linked glycosylation sites in the ECD, 11 have been unambiguously identified. The glycans appear to mostly stabilize the local structure, thus contributing to the folding a

  In the current study, we report the properties of P. anserina mutants carrying mutations in a gene encoding the bi-functional enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase-2). This enzyme catalyzes two opposite reactions (Pilkis et al., 1995, Rider et al., 2004): synthesi

  CDX1 is also a tumor suppressor gene; the ablation of CDX1 and CDX2 results in a significant increase in tumor formation in the colon. CDX1 is regulated by epigenetic modification; the hypermethylation of the CpG island at the promoter is positively associated with severe clinical phenotypes. In add

  The primary physiological role of the HO system is the protection of p0035 from oxidative stress. These cytoprotective effects are attributable both to the degradation of the pro-oxidant heme and to the positive contribution of the metabolites produced during this degradation, namely CO, BV, and BR

  The HCV-Ag immunoassay has been shown from previous studies to be an adequate alternative to the two-stage diagnostic process [6], [9], [16]. Kesli et al. reported a high correlation coefficient of 0.864 when comparing HCV core antigen levels with HCV RNA levels (detected using Qiagen HCV RNA test;

  2022-04-26

  

  CD4 binding to gp120 causes a large scale conformational change of gp120 which involves the gp120 core structure and the transitions of inner-domain layers (layer 1, 2 and 3), but also involves the movement of the major loops (V1, V2 and V3) [16], [17], [18], [19]. For instance, the V2-loop joins th

  We also explored various nitrogen substituents with an aim toward modulating sterics and basicity within the ABH series. No glycine uptake inhibition was detected with non-basic bicycles (data not shown). Isopropyl was the best compromise between desired on-target effect and clearance, however, eff

  Recognition and Repair of DNA Damage DNA is a reactive molecule that is continually challenged by both endogenous and exogenous insults 1., 2.. Cellular metabolites and their byproducts, environmental toxins, and radiation alter the chemical structure of DNA, producing a wide spectrum of DNA damage

  Finally, the results in this article indicate that atomistic MD in conjunction with computational electrophysiology and ion-permeation simulations provide a useful tool for the functional annotation of ion-channel structures. In particular, they exemplify how MD simulations in native lipid membranes

  Introduction Prostate cancer is the most commonly diagnosed cancer and the second leading cause of cancer deaths in men in the United States, accounting for about 30,000 cancer deaths annually [1]. Epidemiological studies that show geographical variations in prostate cancer incidence and mortalit

  The mechanism underlying the anorectic effect of OXM is well established. It is centrally mediated via GLP-1 receptor activation, confirmed by both pharmacological blockade of the GLP-1 receptor, and using GLP-1 receptor knock-out mice [2], [11], [12]. However, the mechanism by which it increases en

  The role of GJs in liver fibrogenesis was studied recently. Studies showed a significant decrease in liver fibrosis in Cx32 knockout mice compared to wild-type mice. Although the mechanism underlying this protective effect of Cx32 deletion is not clear, reduced oxidative stress was suggested as a po

  The inhibitory activities of new compounds against P. aeruginosa were determined in both DTSB media supplemented with heme or free iron and LB media (Table 1). The MIC50 values of the compounds ranged from 42 to 260 μg/mL in DTSB medium and from 26 to 230 μg/mL in LB medium. Among these new inhibito

  Cdc42 is also linked to the adherens junction via IQGAP1, however, it appears to have an opposite effect on junctional stability. When Cdc42 is inactive, IQGAP1 binds to β-catenin, displacing α-catenin, resulting in the loss of α-catenin-linked Acitretin filaments from the adherens junction and redu
