1 In MCs, RT-PCR revealed that high glucose (30 mmol/l) and glucosamine (1 mmol/l) increased mRNA levels for vascular cell adhesion molecule 1 (VCAM-1) and increased the activity of an NF-kappaB enhancer by 1.5- and 2-fold, respectively. Glucose vascular cell adhesion molecule 1 Homo sapiens
2 In MCs, RT-PCR revealed that high glucose (30 mmol/l) and glucosamine (1 mmol/l) increased mRNA levels for vascular cell adhesion molecule 1 (VCAM-1) and increased the activity of an NF-kappaB enhancer by 1.5- and 2-fold, respectively. Glucose vascular cell adhesion molecule 1 Homo sapiens
3 Both glucose and glucosamine dose-dependently increased human VCAM-1 promoter activity. Glucose vascular cell adhesion molecule 1 Homo sapiens
4 In addition, GFAT overexpression activated the VCAM-1 promoter (2.25-fold), with further augmentation by high glucose and abrogation by inhibitors of GFAT, NF-kappaB, and O-glycosylation. Glucose vascular cell adhesion molecule 1 Homo sapiens
5 Inactivation of the two NF-kappaB sites in the VCAM-1 promoter abolished its response to high glucose, glucosamine, and GFAT overexpression. Glucose vascular cell adhesion molecule 1 Homo sapiens
