title: [Analysis of gene expression information in the fat and muscle tissues of pig].
abstract: An in silico study was developed to detect the gene expression profile of pig fat and muscle tissues by using the porcine EST resources and human gene sequences,and thus provided candidate information for basic genetic analysis in meat quality improvement of pig. In this study,a BLAST search was performed to identify homologies between the cDNA sequences of human genes and the ESTs sequences of pig,and the high homologous records were screened out. Four Java programs were developed to retrieve and collect sequences, and analyze the BLAST alignment results. By statistical analysis, it was found that there were at least 2002 genes expressed in the fat and muscle tissues of pig, and 1087 in the fat tissue, 1205 in the muscle respectively (290 genes co-expressed in the two tissues). The top-ranking records were screened out,and meantime, 114 basic active genes (BAGs) were found to express in the two tissues,80 in the fat tissue and 34 in the muscle tissue respectively. The top 10 records were described in the paper. This study was summarized in relation to current meat quality improvement of pig at molecular level.
