  Previous studies from our lab looked at the effect of interfering with crossover helix interactions in TS-DHFR. One study utilized peptide mimetics of the crossover helix to inhibit wild-type TS-DHFR noncompetitively, and with an IC of 230 μM. A second study used a virtual screening approach to iden

  Concluding remarks Introduction Hypertrophic pachymeningitis (HP) is a neurologic disorder characterized by diffuse or focal thickening of the intracranial or spinal dura mater, presenting with intracranial hypertension, cranial nerve palsy and spinal cord dysfunction (Kupersmith et al., 2004;

  2020-06-17

  

  The selective estrogen receptor modulators (SERMs) are another type of estrogen receptor ligands. The main difference between SERMs and xenoestrogens relies on the fact that SERMs present functional duality and are able to act both as agonists and antagonists of the estrogen receptors in different t

  We first confirmed LPS-induction of markers known to induce NF-κB signaling in Caco2BB cells, as established for numerous other cell types [31]. We initially selected this approach to monitor NF-κB activation instead of directly monitoring p65 as it is technically straightforward and provides both u

  This study showed that ER-redox disturbance-associated ER stress is linked to cytoplasmic chaperone signaling, including HSP90 stability and its client protein, eNOS. The highly increased PERK and IRE-1α lead to dissociation with the chaperone protein, thereby decreasing HSP90 stability (Fig. 5B). S

  A decrease in heme levels enables the phosphorylation of eIF2α by HRI and thereby inhibition of eIF2α activity. Indeed, the relatively small change in cytosolic heme levels in SZ chir99021 showed downstream functional consequences manifested by almost 50% elevation in the phosphorylation of eIF2α i

  At present, there have been relatively few studies that evaluated potential correlations between pulmonary and pleura metastases, hilar and mediastinal c-Myc Peptide nodes, and organs associated with distant metastasis and EGFR mutations [33,34,37]. Further research on these relationships is needed

  Kinetic isotope effects (KIEs) inform on bond vibrational changes between the ground state (GS) and TS of a chemical reaction and remain one of the most powerful experimental techniques for interrogating TS structure. KIEs on enzyme reactions measured by the internal Spermine NONOate of labeled sub

  Results Discussion PKR is activated by viral dsRNA and exerts its antiviral effect through phosphorylation of eIF2a. Because eIF2a phosphorylation leads to attenuation of protein synthesis, many viruses have evolved mechanisms to block or suppress PKR activation. Some viruses use alternative t

  Our finding that one enzyme acts both as a primase and a DNAP poses evolutionary and mechanistic questions. In particular, why do cellular organisms require two enzymes to fulfill de novo DNA synthesis? The inability of cellular replicases to perform as primases might be dictated by the challenges a

  DHODH activity has been traditionally measured with the standard colorimetric assay that monitors 2,6-dichloroindophenol (DCIP) reduction as absorbance decrease at 600 nm . This assay has permitted the identification of several families of DHODH inhibitors in a successful high-throughput screening (

  Next, the BE obtained for the different complexes were evaluated. From the BE obtained from our MD simulations, a very good binder can be differentiated from a very weak binder (−11.85 kcal/mol for MTX vs. −6.74 and −3.61 kcal/mol for compounds 14b and 15c, respectively) but ligands with similar bin
