Regulation of vertebrate liver HMG-CoA reductase via reversible modulation of its catalytic activity

Journal of Lipid Research, 1980
We have investigated the comparative biochemistry of in vitro regulation of HMG-CoA reductase (EC 1.1.1.34) in microsomal preparations from the livers of nine vertebrates.

Quinone Reductase 2 Is a Catechol Quinone Reductase [PDF]

Journal of Biological Chemistry, 2008
The functions of quinone reductase 2 have eluded researchers for decades even though a genetic polymorphism is associated with various neurological disorders. Employing enzymatic studies using adrenochrome as a substrate, we show that quinone reductase 2 is specific for the reduction of adrenochrome, whereas quinone reductase 1 shows no activity.

Oral Dosed Organo‐Silica Nanoparticles Restore Glucose Homeostasis and β‐Cell Function in Diabetes Rats

Advanced Functional Materials, EarlyView.
An oral nanoplatform, MOP@T@D, which can maintain glucose homeostasis and restore islet β cells in diabetic rats is developed. It achieves efficient intestinal absorption and liver‐targeted delivery. The nanoparticle disintegrates only in response to hyperglycemia to release insulin on demand and provides antioxidant protection through selenoprotein ...

Comparative studies on the soluble and plasma membrane associated nitrate reductase from Cucumis sativus L.

Acta Societatis Botanicorum Poloniae, 2014
The biochemical comparison between two forms of nitrate reductase from cucumber roots: the soluble enzyme and the plasma membrane-associated one was made. Soluble nitrate reductase was purified on the blue-Sepharose 4B.

Dihydrodipicolinic Acid Reductase

Journal of Biological Chemistry, 1974
Abstract The enzyme dihydrodipicolinic acid reductase catalyzes a pyridine nucleotide-linked reduction of dihydrodipicolinic acid to tetrahydrodipicolinic acid in the biosynthetic pathway leading to diaminopimelic acid and lysine in bacteria. Modification of the procedure published previously and additional purification steps led to a preparation of ...

Aldose and Aldehyde Reductase Exhibit Isocorticosteroid Reductase Activity [PDF]

European Journal of Biochemistry, 1983
In this paper we describe the reduction of corticosteroid metabolites containing the 17 beta-aldol side chain (isocorticosteroids) by aldose and aldehyde reductase from human tissues. Aldose reductase catalyzed the reduction of the aldehydes derived from cortisol and corticosterone at about the same rate, whereas aldehyde reductase preferentially acted

Doxorubicin‐Loaded Metal–Organic Framework for Ferroptosis‐Enhanced Chemotherapy Through Sustained Zn Release and Glutathione Peroxidase Downregulation

Advanced Healthcare Materials, EarlyView.
A robust zinc‐based metal–organic framework (ZnMOF) enables dual functions of doxorubicin delivery and sustained Zn2+ release to trigger ferroptosis‐enhnaced chemotherapy. DOX@ZnMOF effectively depletes intracellular glutathione, suppresses GPX4, and elevates reactive oxygen species, leading to efficient oxidative DNA damage and apoptosis.

Activation of HMG-CoA reductase by microsomal phosphatase

Journal of Lipid Research, 1983
HMG-CoA reductase activity can be modulated by a reversible phosphorylation-dephosphorylation with the phosphorylated form of the enzyme being inactive and the dephosphorylated form, active. Phosphatases from diverse sources, including cytosol, have been

Simvastatin Restores Uteroplacental Hemodynamics and Trophoblast Function in Obstetric Antiphospholipid Syndrome in a Placenta‐on‐a‐Chip Model

Advanced Healthcare Materials, EarlyView.
Simvastatin mitigates placental hypoperfusion in OAPS by ameliorating abnormal uteromaternal hemodynamics and enhancing trophoblast invasion via optimized endothelial cell interactions under pathological shear stress, as evidenced by results from a placenta‐on‐a‐chip platform.
