    intracellular,nucleus
    basic FUNCTION
  • aldo-ketoreductase, reducing aromatic and aliphatic aldehydes, with less activity than AKR1A1
  • obligatory mediator of TNF-alpha signaling leading to an increase in the expression of adhesion molecules and increased binding of monocytes to the endothelium (
  • implicated in the development of a number of diabetic complications
  • plays an important role in the regulation of hepatic PPARalpha phosphorylation and activity and lipid homeostasis
  • potent regulator of TGF-B1 induced expression of fibronectin in human mesangial cells, suggesing that inhibition of this enzyme may be useful to prevented extracellular matrix (ECM) deposition in glomerulosclerosis
  • first enzyme in the polyol pathway
  • prostaglandin F(2A) (PGF2A) synthase, which catalyze the NADPH-dependent reduction of PGH(2), a common intermediate of various prostanoids, to form PGF(2A)
  • regulates vascular smooth muscle cell proliferation by modulating G1/S phase transition of cell cycle

    over-expression in some types of hepatocellular carcinomas (HCCs) is (T3)receptor -dependent and might play a crucial role in the development of HCC
    Susceptibility
  • not associated to susceptibility to diabete nephropathy
  • to diabetic retinopathy in type 2 diabetes
  • Variant & Polymorphism other
  • type-2 diabetics with the CC genotype at C(-106)T polymorphism were more susceptible for developing retinopathy as a result of chronic hyperglycemia than those with the CT or TT genotype
