Aldose reductase from human skeletal and heart muscle. Interconvertible forms related by thiol-disulfide exchange.
Aldose reductase was purified from human skeletal and heart muscle by a rapid and efficient scheme involving Red Sepharose chromatography, chromatofocusing on Pharmacia PBE 94, and hydroxylapatite high pressure liquid chromatography. The scheme afforded homogeneous enzyme, 65% recovery, in 2 days. All muscle samples express aldose reductase but not the closely related aldehyde reductase. Aldose...
متن کاملAldose reductase inhibitory compounds from Glycyrrhiza uralensis.
We evaluated the inhibitory effects of components from the root of Glycyrrhiza uralensis (G. uralensis) on aldose reductase (AR) and sorbitol formation in rat lenses with high levels of glucose as part of our ongoing search of natural sources for therapeutic and preventive agents for diabetic complications. In order to identify the bioactive components of G. uralensis, 5 prenylated flavonoids (...
متن کاملRegulation of vascular smooth muscle cell growth by aldose reductase.
Aldose reductase (AR) is a broad-specificity aldo-keto reductase with wide species and tissue distribution. The enzyme has been implicated in the development of pleiotropic complications of long-term diabetes. However, the euglycemic function of the enzyme remains unclear. To examine its potential role in cell growth, changes in AR mRNA and protein were measured in human aortic smooth muscle ce...
متن کاملStructure of aldose reductase from Giardia lamblia
Giardia lamblia is an anaerobic aerotolerant eukaryotic parasite of the intestines. It is believed to have diverged early from eukarya during evolution and is thus lacking in many of the typical eukaryotic organelles and biochemical pathways. Most conspicuously, mitochondria and the associated machinery of oxidative phosphorylation are absent; instead, energy is derived from substrate-level pho...
متن کاملAldose reductase mediates mitogenic signaling in vascular smooth muscle cells.
Abnormal vascular smooth muscle cell (VSMC) proliferation is a key feature of atherosclerosis and restenosis; however, the mechanisms regulating growth remain unclear. Herein we show that inhibition of the aldehyde-metabolizing enzyme aldose reductase (AR) inhibits NF-kappa B activation during restenosis of balloon-injured rat carotid arteries as well as VSMC proliferation due to tumor necrosis...
