Aldose 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...
متن کاملAldose reductase localization in human retinal mural cells.
A hallmark of early diabetic retinopathy is the selective loss of the retinal mural cells (pericytes) from vessels. Using antibodies prepared against purified human placental aldose reductase, the presence of the enzyme aldose reductase can be demonstrated immunohistochemically in the cytoplasm of retinal mural cells of trypsin-digested human retinal vessels. This enzyme, which reduces various ...
متن کاملHuman aldose reductase and human small intestine aldose reductase are efficient retinal reductases: consequences for retinoid metabolism.
Aldo-keto reductases (AKRs) are NAD(P)H-dependent oxidoreductases that catalyse the reduction of a variety of carbonyl compounds, such as carbohydrates, aliphatic and aromatic aldehydes and steroids. We have studied the retinal reductase activity of human aldose reductase (AR), human small-intestine (HSI) AR and pig aldehyde reductase. Human AR and HSI AR were very efficient in the reduction of...
متن کاملRedox activation of aldose reductase in the ischemic heart.
Aldose reductase (AR) reduces cytotoxic aldehydes and glutathione conjugates of aldehydes derived from lipid peroxidation. Its inhibition has been shown to increase oxidative injury and abolish the late phase of ischemic preconditioning. However, the mechanisms by which ischemia regulates AR activity remain unclear. Herein, we report that rat hearts subjected to ischemia, in situ or ex vivo, di...
