p59fyn, a protein tyrosine kinase belonging to the src-family, is involved in the regulatory mechanism of acute response to ethanol in the central nervous system. A previous report showed an association between src-family kinase activity and fatty acid oxidation, and it also reported that hepatic free fatty acid levels were low in Fyn−/− mice. We examined, using Fyn−/− mice whether Fyn is also involved in fatty acid metabolism and the development of pathological changes in the liver in response to chronic ethanol consumption. C57BL/6J Fyn−/− and Fyn+/+ mice were fed for 8 weeks with either a liquid diet comprising ethanol or one in which the calories from ethanol were replaced with carbohydrates. Chronic ethanol consumption for 8 weeks resulted in remarkable hepatic steatosis in Fyn+/+ mice but not in Fyn−/− mice. Chronic ethanol consumption induced a significant decrease in hepatic FFA and triglyceride levels in Fyn−/− mice. Levels of interleukin-6, which is associated with the enhancement of fatty acid oxidation, was also increased significantly in the livers of ethanol-fed Fyn−/− mice. The results suggest that Fyn is involved in the enhancement of fatty acid oxidation and the development of hepatic steatosis caused by chronic ethanol consumption. 相似文献

We developed computer-based methods for constructing a nonredundant mouse full-length cDNA library. Our cDNA library construction process comprises assessment of library quality, sequencing the 3' ends of inserts and clustering, and completing a re-array to generate a nonredundant library from a redundant one. After the cDNA libraries are generated, we sequence the 5' ends of the inserts to check the quality of the library; then we determine the sequencing priority of each library. Selected libraries undergo large-scale sequencing of the 3' ends of the inserts and clustering of the tag sequences. After clustering, the nonredundant library is constructed from the original libraries, which have redundant clones. All libraries, plates, clones, sequences, and clusters are uniquely identified, and all information is saved in the database according to this identifier. At press time, our system has been in place for the past two years; we have clustered 939,725 3' end sequences into 127,385 groups from 227 cDNA libraries/sublibraries (see http://genome.gse.riken.go.jp/). 相似文献
