inhibition of enzyme in neural stem cells exposed to high glucose concentration results in decrease of oxidative stress, restoration of cell viability and proliferation, and reduction of apoptotic cell death. Inhibition attenuates the down-regulation of glucose transporter 1 expression
fidarestat
-
fidarestat decreases doxorubicin-induced upregulation of CD11b in THP-1 monocytes. Fidarestat attenuates doxorubicin-induced upregulation of IL-6, IL-1bta, and Nos2 in murine BMDM. Fidarestat also attenuates doxorubicin-induced activation and infiltration of multiple subsets of inflammatory immune cells identified by expression of markers CD11b+, CD11b+F4/80+, Ly6C+CCR2high, and Ly6C+CD11b+ in the mouse spleen and liver. Upregulation of markers of mitochondrial biogenesis PGC-1alpha, COX IV, TFAM, and phosphorylation of AMPKalpha1 (Ser485) is observed in THP-1 cells and livers of mice treated with doxorubicin in combination with fidarestat

enzyme knockdown reduces the development of diet-induced liver fibrosis
evolution
aldose reductase (AKR1B1) is a member of the aldo-keto reductase superfamily
evolution
aldose reductase belongs to the aldoketo reductase superfamily, which includes several enzymes that catalyze oxidation and reduction reactions involved in various cellular processes
malfunction
carnosine-propanals are converted to carnosine-propanols in the lysates of heart, skeletal muscle, and brain tissue from wild-type but not AR-null mice. In comparison with wild-type mice, the urinary excretion of carnosine-propanols is decreased in AR-null mice, overview
malfunction
enzyme deficiency-induced microglia/macrophages induce the M2 rather than the M1 response (classically activated pro-inflammatory (M1) or alternatively activated anti-inflammatory (M2) cells) and promote locomotion recovery after spinal cord injury in mice. In the in vitro experiments, microglia cell lines (N9 or BV2) are treated with the enzyme inhibitor fidarestat. Enzyme inhibition causes 4-hydroxynonenal accumulation, which induces the phosphorylation of the cAMP response element-binding. Enzyme deficiency causes NF-kappaB downregulation and CREB upregulation after spinal cord injury in mice
malfunction
lipopolysacchride-induced RMG activation and migration into the inner nuclear layer or outer nuclear layer is largely prevented by enzyme inhibitors or in aldose reductase null mice, or is exacerbated in transgenic mice that over-express the enzyme
metabolism
AKR1B1 functions in the polyol pathway as an NADPH-dependent enzyme, catalyzing the reduction of glucose to sorbitol, which is then converted to fructose by sorbitol dehydrogenase
metabolism
aldose reductase is the only enzyme responsible for reducing glucose to sorbitol in the polyol pathway of glucose metabolism
physiological function
aldose reductase regulates cytokine and chemokine production in the eye and mediates retinal microglia activation, role of the enzyme in RMG activation and migration in vivo, overview. Retinal microglia (RMG) are one of the major immune cells in charge of surveillance of inflammatory responses in the eye. In the absence of an inflammatory stimulus, RMG reside predominately in the ganglion layer and inner or outer plexiform layers. Under stress RMG become activated and migrate into the inner nuclear layer or outer nuclear layer. Activated RMG in cell culture secrete pro-inflammatory cytokines in a manner sensitive to downregulation by aldose reductase inhibitors. Aldose reductase expression in retinal microglia may contribute to the proinflammatory phenotypes common to various eye diseases such as uveitis and diabetic retinopathy
physiological function
aldose reductase regulates microglia/macrophages polarization through the cAMP response element-binding protein after spinal cord injury in mice, mechanism, overview
physiological function
lipid peroxidation generates unsaturated aldehydes, such as acrolein, that form conjugates with histidyl dipeptides.Carnosine-aldehyde conjugates form covalent adducts with proteins and are reduced by aldose reductase. Detoxification of carnosine-aldehyde by aldose reductase prevents protein carnosinylation. Aldose reductase prevents tissue injury due to aldehyde-carnosine conjugates. Carnosine-propanals are converted to carnosine-propanols in the lysates of heart, skeletal muscle, and brain tissue from wild-type but not AR-null mice. Role of aldose reductase as a critical regulator of protein carnosinylation and carnosine-mediated tissue protection, overview
physiological function
-
aldose reductase metabolizes both free and phospholipid aldehydes and exacerbates atherosclerotic lesion formation, increase in lesion area attributable to inhibition of the enzyme or deletion of the gene encoding the enzyme occurs in both male and female mice, phenotype of enzyme-deficient male and female mice with increases in arterial lesions, macrophage accumulation and interstitial fibrosis, and decreases smooth muscle cell content of arterial lesions, detailed overview
physiological function
-
aldose reductase catalyzes the rate-limiting reduction of glucose to sorbitol with the aid of cofactor NADPH. The enzyme induces elevations on the level of CYP2E1 expression, reactive oxygen species, mRNA expression of TNF-alpha, and IL-6, confirmed in AML12 hepatocytes. The enzyme is involved in the development of methionine-choline-deficient diet-induced steatohepatitis in diabetic db/db mice, and plays a role in the development of diabetic complications. The enzyme alleviates the diet-induced (via methionine-choline-deficient (MCD) diet) liver inflammation and fibrosis in db/db mice, probably through dampening CYP2E1 mediated-oxidative stress and ameliorating the expression of pro-inflammatory cytokines
