[CDNA microarray on differentially expressed genes of adipose tissue in two breeds chicken]

cDNA microarray containing 9024 cDNAs was used to construct gene expression profile in order to screen differentially expressed genes of adipose tissue between broiler and Bai' er and investigate the molecular mechanism related with body fatness traits between the two breeds. Sixty seven differentially expressed genes, being involved in fat metabolism, energy metabolism, cytoskeleton, transcription and splicing factor, protein synthesis and degradation, were screened out. Furthermore, some genes that had no annotation in GenBank were screened out, they were presumed to be unknown new genes. The roles that they may play in chicken fat metabolism need clarify later.
