Modulation of oxidative damage by selenium compounds [PDF]

, 2015
Myeloperoxidase (MPO) is the primary enzyme responsible for the production of strong oxidants by neutrophils in response to pathogens. One of the major oxidants produced is hypochlorous acid (HOCl), which can react with amine groups to form the secondary

ECM‐Stiffness Mediated Persistent Fibroblast Activation Requires Integrin and Formin Dependent Chromatin Remodeling

Advanced Science, EarlyView.
Prolonged exposure to stiff extracellular matrix drives cancer‐associated fibroblasts into a persistently activated myofibroblast state. Two parallel pathways are identified: β1 integrin activation smoothens the nuclear lamina to reduce lamin–chromatin contacts, while the formin mDia2 regulates nuclear actin to alter chromatin organization.

Growth Inhibition by Selenium Compounds [PDF]

, 1998
A number of selenium compounds have been shown to have anticancer properties. The mechanism by which selenium has anticarcinogenic effects is not understood although it is likely to be related to its ability to inhibit cell growth and induce apoptosis ...

Production of Polyselenodipenicillamines, Unique Selenium Compounds

Chemical and Pharmaceutical Bulletin, 2010
Selenite (H(2)SeO(3)) reacts with thiol compounds (RSH) under acidic conditions to form selenotrisulfides (RSSeSR, i.e. monoselenodithiols). The stoichiometry of the reaction is proposed as 4RSH+H(2)SeO(3)-->RSSeSR+RSSR+3H(2)O. Surprisingly, we found novel polynuclear selenium-containing compounds, i.e.

Tetrastigma Hemsleyanum Polysaccharide Suppresses Triple‐Negative Breast Cancer by Disrupting the Hippo‐YAP/TEAD4‐PDIA4 Axis and Endoplasmic Reticulum Stress Adaptation

Advanced Science, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) exhibits addiction to chronic endoplasmic reticulum (ER) stress, which sustains an aggressive metastatic phenotype through activation of the unfolded protein response (UPR). Here, we identify a previously unrecognized “ER‐stress addiction” axis in which the Hippo pathway effector TEAD4 directly ...

Selenium as a Modulator of Efficacy and Toxicity of Chemotherapy and Radiation

, 2011
Selenium (Se) is an essential trace mineral required in maintaining health in humans. Recent research has demonstrated that Se shows promise as an agent that can reduce the harmful side-effects of chemotherapy (CT) and radiotherapy (RT), while not ...

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

Multi‐Omics Profiling Reveals Immunomodulatory and Pro‐Regenerative Effects of a Graphene Oxide–Collagen Scaffold in Massive Rotator Cuff Tears

Advanced Science, EarlyView.
A graphene oxide/collagen scaffold is developed for chronic massive rotator cuff tear repair. The scaffold improves compressive stability, supports reparative mesenchymal differentiation, and modulates the immune microenvironment. In chronic MRCT models, it reduces muscle degeneration, enhances tendon–bone regeneration, and improves functional recovery,
