Activation of the Listeria monocytogenes Virulence Program by a Reducing Environment. [PDF]

, 2017
Upon entry into the host cell cytosol, the facultative intracellular pathogen Listeria monocytogenes coordinates the expression of numerous essential virulence factors by allosteric binding of glutathione (GSH) to the Crp-Fnr family transcriptional ...

High‐Efficiency Carriers’ Separation Strategy Based Ultrasmall‐Bandgap CuWO4 Sono‐Enhances GSH Antagonism for Cuproptosis Cascade Immunotherapy

Advanced Science, EarlyView.
This study prepares copper tungstate (CuWO4, CWO) nanoparticles for synergistic sono‐enhanced cuproptosis‐based cancer therapy. With an ultrasmall bandgap (1.71 eV), CWO facilitates efficient charge carrier separation under ultrasound, enhancing the generation of reactive oxygen species and the controlled release of Cu2+ ions cascade amplify oxidative ...

Investigation of electrochemical properties of biologically active tyolic compounds on a gold-carbon-containing electrode [PDF]

, 2018
The electrochemical behavior of biologically active thiol compounds on a gold-carbon-containing electrode in solutions was investigated in order to suggest their model behavior with respect to ROS. It was found that the recovered forms of glutathione and

PP1A Modulates the Efficacy of Lenvatinib Plus ICIs Therapy by Inhibiting Ferroptosis in Hepatocellular Carcinoma

Advanced Science, EarlyView.
PP1A dephosphorylates Keap1 at the S104 site, stabilizing and promoting the nuclear translocation of Nrf2, which upregulates the expression of antioxidant genes and PD‐L1. This leads to suppressed ferroptosis and enhanced immune evasion, thereby improving the efficacy of TKI and ICI combination therapy.

The Oxidized Protein Repair Enzymes Methionine Sulfoxide Reductases and Their Roles in Protecting against Oxidative Stress, in Ageing and in Regulating Protein Function

Antioxidants, 2018
Cysteine and methionine residues are the amino acids most sensitive to oxidation by reactive oxygen species. However, in contrast to other amino acids, certain cysteine and methionine oxidation products can be reduced within proteins by dedicated ...

An albumin-derived peptide scaffold capable of binding and catalysis [PDF]

, 2012
We have identified a 101-amino-acid polypeptide derived from the sequence surrounding the IIA binding site of human albumin. The polypeptide contains residues that make contact with ligands as warfarin in the parent protein, and eight cysteine residues ...

Accelerating Sono‐Piezoelectric Charge Transport for Antibacterial Therapy and Bone Regeneration by Metal‐Deficient TiO2 Spin‐Polarization Effect

Advanced Science, EarlyView.
The deficient TiO2 (DTO) and Barium titanate (BTO) heterojunction treats osteomyelitis through SDT. The spin‐polarization effect induced by the unpaired spin electrons in Ti atoms can expedite the transfer of ultrasonic piezoelectric charges in BTO, enhancing surface sonocatalytic efficiency.

GL-BLSTM: a novel structure of bidirectional long-short term memory for disulfide bonding state prediction [PDF]

arXiv, 2018
Background: Disulfide bonds are crucial to protein structural formation. Developing an effective method topredict disulfide bonding formation is important for protein structural modeling and functional study. Mostcurrent methods still have shortcomings, including low accuracy and strict requirements for the selection ofdiscriminative features. Results:

GEM Operation in Negative Ion Drift Gas Mixtures [PDF]

, 2003
The first operation of GEM gas gain elements in negative ion gas mixtures is reported. Gains up to several thousand were obtained from single-stage GEMs in carbon disulfide vapor at low pressure, and in mixtures of carbon disulfide with Argon and Helium, some near 1 bar total pressure.

Inhibition of Heat Shock Protein 90β by Catalpol: A Potential Therapeutic Approach for Alleviating Inflammation‐Induced Cartilage Injuries in Osteoarthritis

Advanced Science, EarlyView.
The schematic diagram delineates the chondroprotective effects of Ca‐bMSN in OA models. The upper portion of the diagram depicts the synthesis process of Ca‐bMSN. The lower section illustrates the post‐injection of Ca‐bMSN in joint cavity, catalpol released and subsequently mediates the reduction of oxidative stress, ECM catabolism, apoptosis, and ...
