Abstract

Glucose deprivation of L6 myocytes results in the upregulation of glucose transporter activity, protein and mRNA. We have investigated the downregulation of transporter gene expression by glucose and other hexoses in glucose-deprived L6 myocytes. Glucose transport activity was measured as the uptake of 3H-2-deoxyglucose. Transporter protein and mRNA were detected by immunoblot and Northern blot analysis, respectively, with probes to the rat brain glucose transporter. Glucose deprivation of myocytes, in the absence and presence of insulin, increased 3H-2-deoxyglucose uptake, transporter protein and mRNA levels. Refeeding with glucose reversed the glucose deprivation effects on transport activ..
