Effects of chronic ingestion of catechin-rich green tea on hepatic gene expression of gluconeogenic enzymes in rats
Normal rats were given catechin-rich green tea as drinking fluid and the effects on hepatic gene expression were examined. The results of DNA microarray analysis and quantitative real-time reverse transcription-polymerase chain reaction indicated the down-regulated expression of genes for glucose-6-...

description | Normal rats were given catechin-rich green tea as drinking fluid and the effects on hepatic gene expression were examined. The results of DNA microarray analysis and quantitative real-time reverse transcription-polymerase chain reaction indicated the down-regulated expression of genes for glucose-6-phosphatase (G6Pase) and fatty acid synthase, and the up-regulated expression of peroxisome proliferator activated receptor α in the rats given green tea for 4 weeks as compared with the water-given animals. One may expect anti-diabetic activity by catechin-rich green tea through its chronic down-regulatory effect on G6Pase expression. |
