1 The impact of glyLDL on the expression and activity of eNOS in vascular endothelial cells (EC) remains unknown. glyldl nitric oxide synthase 3 Homo sapiens
2 The present study investigated the effect of glyLDL on the levels of protein, mRNA and activity of eNOS in cultured human umbilical vein EC. glyldl nitric oxide synthase 3 Homo sapiens
3 The results demonstrated that incubation of EC with physiological concentrations of glyLDL significantly reduced the abundances of eNOS protein in EC with the maximal inhibition at 100mug/ml for 24h. glyldl nitric oxide synthase 3 Homo sapiens
4 Blocking antibody against the receptor for advanced glycation end products (RAGE) prevented glyLDL-induced downregulation of eNOS in EC. glyldl nitric oxide synthase 3 Homo sapiens
5 Farnesyl-transferase inhibitor-276, an H-Ras antagonist, normalized glyLDL-induced downregulation of eNOS and prevented glyLDL-induced upregulation of H-Ras in EC membrane. glyldl nitric oxide synthase 3 Homo sapiens
6 Treatment with 4-phenylbutyric acid, an endoplasmic reticulum (ER) stress antagonist, prevented glyLDL-induced eNOS downregulation in EC. glyldl nitric oxide synthase 3 Homo sapiens
7 ER stress induced by glyLDL is possibly involved in eNOS downregulation. glyldl nitric oxide synthase 3 Homo sapiens
