Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Bisphenol A Induces Neuronal Apoptosis and Oxidative Stress Through TRPV4 Channel Signaling Pathways: Protective Role of Alpha‐Lipoic Acid

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), an environmental toxin, exerts adverse effects by increasing mitochondrial (mROS) and intracellular (iROS) reactive oxygen species, apoptosis, and Ca2+ influx in neurological diseases. However, antioxidants can mitigate these detrimental effects. This study aimed to investigate the protective role of antioxidant alpha‐lipoic

Is Deuterium Sequestering by Reactive Carbon Atoms an Important Mechanism to Reduce Deuterium Content in Biological Water?

FASEB BioAdvances, EarlyView.
Deuterium, a heavy isotope of hydrogen, is universal in nature, but it disrupts the mitochondrial ATPase pumps. One mechanism that biological organisms may use to reduce deuterium levels in the mitochondria is to sequester deuterium bound to carbon atoms in a small set of organic molecules that have a unique configuration to support such trapping ...

Solution Structures of \u3cem\u3eMycobacterium tuberculosis\u3c/em\u3e Thioredoxin C and Models of Intact Thioredoxin System Suggest New Approaches to Inhibitor and Drug Design [PDF]

, 2013
Here, we report the NMR solution structures of Mycobacterium tuberculosis (M. tuberculosis) thioredoxin C in both oxidized and reduced states, with discussion of structural changes that occur in going between redox states.

Opportunities and Challenges of Population Pharmacogenomics

Annals of Human Genetics, EarlyView.
ABSTRACT Pharmacological responses can vary significantly among patients from different ethnogeographic backgrounds. This variability can, at least in part, be attributed to population‐specific genetic patterns in genes involved in drug absorption, distribution, metabolism, and excretion, as well as in genes associated with drug‐induced toxicity ...

Molecular and cellular mechanisms underlying gyrate atrophy: Why is the retina primarily affected?

Acta Ophthalmologica, EarlyView.
Abstract Gyrate atrophy of the choroid and retina (GACR; OMIM #258870) is a rare early‐onset autosomal recessive disorder, caused by bi‐allelic pathogenic variants in the gene coding for ornithine aminotransferase (OAT) resulting in hyperornithinaemia.

Glutaminase‐1 Mediated Glutaminolysis to Glutathione Synthesis Maintains Redox Homeostasis and Modulates Ferroptosis Sensitivity in Cancer Cells

Cell Proliferation, EarlyView.
GLS1‐mediated glutaminolysis supports GSH synthesis in cancer cells. GLS1 KO increases ROS, downregulates GPX4, and upregulates GPX1, making cells more sensitive to ferroptosis. Combining GLS1 or GPX1 inhibitors with a GPX4 inhibitor synergistically suppresses cancer growth.

Genomic context analysis enables the discovery of an unusual NAD‐dependent racemase in phosphonate catabolism

The FEBS Journal, EarlyView.
The authors identify PbfF (previously annotated as a NAD‐dependent dehydrogenase) as a hitherto unknown enzyme in phosphonate catabolism. Guided by genome context analysis, they show that PbfF is actually a racemase, serving to degrade the natural compound (S)‐2‐amino‐1‐hydroxyethylphosphonate (S‐HAEP).

Thionicotinamide-NADP, a Nucleotide Analog Interfering with Ferredoxin-NADP Reductase/Ferredoxin Interaction

Zeitschrift für Naturforschung B, 1972
Diaphorase and transhydrogenase activities (system NADPH; dichlorophenolindophenol and NADPH;NAD, respectively) of ferredoxin-NADP reductase are increased by ferredoxin. Reduced thionicotinamide-NADP (TN-NADPH) only slightly inhibits these activities with no ferredoxin present in the assay, but the activity increments in the presence of ferredoxin are ...

The molecular mechanisms of defensive‐grade organic acid biosynthesis in ground beetles

Insect Molecular Biology, EarlyView.
Formic acid and methacrylic acid are the primary defensive chemicals in the pygidial gland secretions of Platynus angustatus and Pterostichus moestus, respectively. Comparative transcriptomics suggests the folate cycle and valine catabolism may be involved in the biosynthesis of formic acid and methacrylic acid, respectively.
