为了直接定量稳态葡萄糖转运蛋白mRNA水平,采用北方印迹杂交技术,以大鼠脑葡萄糖转运蛋白cDNA为探针,研究了大鼠脑源性/Hep G2葡萄糖转运蛋白基因表达的发育调控。结果表明,在个体发育过程中,葡萄糖转运蛋白mRNA水平的组织特异性模式不同;而在大脑中,从胚胎发育20天到出生后50天,信息水平持续增加,其他器官如心脏、肺、肝脏和肌肉在20天的胎儿和1天的新生儿中表达最高水平的葡萄糖转运蛋白mRNA,随后降至极低水平。葡萄糖转运蛋白mRNA的相对表达在不同的组织中,在胎儿和成人阶段,进行了分析,使用溶液杂交-核糖核酸酶保护试验。这种方法表明,虽然心脏在胎儿20天时表达最高水平的葡萄糖转运蛋白mRNA,但大脑在成人阶段表现出最高水平。这些结果表明葡萄糖转运蛋白基因表达的组织特异性个体发育模式,这表明葡萄糖转运蛋白基因产物的发育作用。
The developmental regulation of rat brain-derived/Hep G2 glucose transporter gene expression was studied by means of Northern blot hybridization, using a rat brain glucose transporter cDNA probe, in order to directly quantify steady state glucose transporter mRNA levels. The results obtained showed different tissue-specific patterns of glucose transporter mRNA levels during ontogenesis; while in brain there was a sustained increase in the levels of the message from 20 days embryogenesis until 50 days postnatal, other organs such as heart, lung, liver, and muscle expressed maximal levels of the glucose transporter mRNA in 20-day fetuses and 1-day neonates, decreasing subsequently to very low levels. The relative expression of the glucose transporter mRNA in the different tissues, at both fetal and adult stages, was analyzed using a solution hybridization-RNase protection assay. This approach revealed that, while the heart expresses the highest levels of glucose transporter mRNA at 20 days of fetal life, the brain shows the highest levels at the adult stage. These results indicate a tissue-specific ontogenic pattern of glucose transporter gene expression, suggesting a developmental role for this glucose transporter gene product.
