- Two non-normalized cDNA libraries of uteri from Danish Landrace and Chinese Erhualian pigs were constructed, and 13,756 expressed sequence tags (ESTs) were randomly sequenced. The ESTs were clustered by Phrap software, and 6,139 distinct tentative consensus sequences were produced, including 2,730 contigs and 3,409 singlets. Using Blast tools, these 6,139 candidate genes were compared to the nr and nt databases; 5,210 of them were assigned putative functions, whereas 929 potentially represent new genes. Highly expressed genes appear to be associated with basic energy metabolism, transferase activity, localization, cellular physiological process, protein binding, and nucleic acid binding. Antileukoproteinase was the most highly expressed gene, corresponding to endometrial differentiation and conceptus or fetal development.
