AI Article Synopsis

  • β-Glycoprotein I is a key protein involved in antiphospholipid syndrome (APS), a disorder that leads to blood clots and can cause complications in pregnancy.
  • In healthy individuals, β-glycoprotein I exists in a balanced ratio of oxidized and reduced forms, but this balance is disrupted in conditions like APS, age-related macular degeneration, and septic infections.
  • Researchers have created tests to measure the levels of different forms of β-glycoprotein I in blood, which may help in assessing risks and predicting outcomes in these medical conditions.

Article Abstract

β-Glycoprotein I is the major autoantigen in the antiphospholipid syndrome (APS), a prothrombotic disorder characterized by the occurrence of either venous or arterial thrombosis. In women it is also associated with an increased risk of obstetric complications such as recurrent miscarriages. We have identified that the plasma protein β-glycoprotein I in healthy individuals exists in an optimal ratio between two distinct forms, an oxidized and free thiol, reduced form. This ratio is disrupted in pathophysiological conditions associated with increased oxidative stress such as the APS, but also in the setting of age-related macular degeneration and gram-negative sepsis. We have developed assays that quantify plasma/serum levels of total and free thiol β-glycoprotein I which can potentially be used for risk stratification and prognostic purposes in the early stages of the aforementioned conditions.

The thiol-ene reaction between an alkene and a thiol can be exploited for selective labelling of cysteine residues in protein profiling applications. Here, we explore thiol-ene activation in systems from chemical models to complex cellular milieus, using UV, visible wavelength and redox initiators. Initial studies in chemical models required an oxygen-free environment for efficient coupling and showed very poor activation when using a redox initiator.

Metallofullerenol Gd@C(OH) preserves human erythrocyte plasma membrane integrity from AAPH-induced oxidative stress: molecular mechanisms and antioxidant activity.

Metallofullerenols and fullerenols have attracted attention due to their remarkable ability to interact with various biologically relevant molecules, paving the way for biomedical applications, ranging from medical imaging techniques to drug carriers, acting with increased efficiency and reduced side effects. In this work, we investigated the effects of two fullerene derivatives, Gd@C(OH) and C(OH), on erythrocyte membrane components under oxidative stress conditions induced by 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) as a source of peroxyl radicals. The results demonstrated that gadolinium encapsulation within the fullerene cage enhanced the electron affinity of Gd@C(OH), resulting in stronger antioxidant activity.

Melatonin increases Pb tolerance in P. ovata seedlings via the regulation of growth and stress-related phytohormones, ROS scavenging and genes responsible for melatonin synthesis, metal chelation, and stress defense. Lead (Pb) is a highly toxic heavy metal that accumulates in plants through soil and air contamination and impairs its plant growth and development.

Total free thiols are an important marker of the whole-body redox state, which has been shown to be associated with clinical outcome in health and disease. Recent investigations have suggested that increased insight may be gained by monitoring alterations of redox state in response to exercise and hypoxia and to monitor redox trajectories in disease settings. However, conducting such studies is challenging due to the requirement for repeated venous blood sampling and intensive lab work.

Molecular Mechanism of Unexpected Metal-Independent Hydroxyl Radical Production by Mercaptotriazole and HO.

It is well known that hydroxyl radical (OH) can be largely produced either through the classic iron-mediated inorganic-Fenton system or our recently discovered haloquinones/HO organic-Fenton-like system, but rarely produced via thiol compounds. Here, unexpectedly, we found that OH can be unequivocally generated by incubation of HO and mercaptotriazole (MTZ), a typical heterocyclic thiol which has been used as an environmentally friendly corrosion inhibitor for mild steel. By the complementary applications of HPLC-MS and oxygen-18 isotope-labeling method, MTZ-derived sulfenic (MTZ-SOH) and sulfinic acids were detected and identified as transient intermediates, and sulfonic acid as final products.
