Abstract

A gene-based approach was used to annotate 322 168 cattle expressed sequence tags (ESTs) based on human genes in order to census the transcriptomes, analyze their expression similarities, and identify genes preferentially expressed in different bovine tissues and (or) organs. Of the 34 157 human coding genes used in a standalone BLAST search, 14 928 could be matched with provisional orthologous sequences in a total of 230 135 bovine ESTs. The remaining 92 033 bovine ESTs were estimated to represent an additional 5970 genes in cattle. On average, ∼8600 genes were estimated to be expressed in a single tissue and (or) organ and 13 000 in a pooled tissue library. On the basis of the estimated numbers of genes, no more than 3% of genes would be missed when ∼34 000 ESTs were sequenced from a single tissue and (or) organ library and ∼40 000 ESTs from a pooled source, respectively. Cluster analyses of the gene expression patterns among 12 single tissues and (or) organs in cattle revealed that their expression similarities would depend on physiological functions. In addition, a total of 1502 genes were identified as preferentially expressed genes in these 12 single tissues and (or) organs with LOD (logarithm of the odds, base 10) ≥ 3.0. Therefore, our study provides some insights for further investigating the developmental and functional relations of various tissues and organs in mammals.
