Requirement of glucose metabolism for regulation of glucose transporter type 2 (GLUT2) gene expression in liver.
Previous studies have shown that glucose increases the glucose transporter (GLUT2) mRNA expression in the liver in vivo and in vitro. Here we report an analysis of the effects of glucose metabolism on GLUT2 gene expression. GLUT2 mRNA accumulation by glucose was not due to stabilization of its transcript but rather was a direct effect on gene transcription. A proximal fragment of the 5' regulat...
متن کاملRegulation of glucose-transporter gene expression by insulin in cultured human fibroblasts.
To clarify the effect of insulin on glucose-transporter (GT) biosynthesis, we determined GT mRNA levels in human cultured skin fibroblasts, using HepG2 GT cDNA as a probe. Insulin specifically increased the GT mRNA level in a time- and dose-dependent manner. Time-course study demonstrated that the mRNA level peaked within 3 h of insulin (1 x 10(-7) M) addition. After remaining elevated for seve...
متن کاملDifferential regulation of glucose transporter expression by estrogen and progesterone in Ishikawa endometrial cancer cells.
Estrogen replacement therapy and other unopposed estrogen treatments increase the incidence of endometrial abnormalities, including cancer. However, this effect is counteracted by the co-administration of progesterone. In the endometrium, glucose transporter (GLUT) expression and glucose transport are known to fluctuate throughout the menstrual cycle. Here, we determined the effect of estrogen ...
متن کاملexpression of glucose transporter 4 (glut4) is increased by cinnamaldehyde in c2c12 mouse muscle cells
background: in diabetes mellitus because of the absence or insufficient sensitivity to insulin, glucose transporter protein in cell membrane, glucose transporter 4, is decreased. glut4 is the major glucose transporter in skeletal muscle and adipose tissue, which is under control of insulin. it remains, however, unclear whether cinnamaldehyde plays a regulatory role(s) or not. objectives: the ob...
متن کاملRegulation of Mammalian Gene Expression by Glucose.
Recent data suggest that cells from species as diverse as yeast and mammals may use similar mechanisms to detect changes in nutrient concentration. Here we review recent advances in understanding how glucose regulates gene transcription in mammals.
