title: Analysis of differentially expressed genes in ovaries of polytocous versus monotocous dairy goats using suppressive subtractive hybridization.
abstract: In this study, suppressive subtractive hybridization (SSH) was performed to screen differentially expressed genes in ovarian tissues between polytocous and monotocous goats. From the SSH cDNA library, we obtained 29 differentially expressed sequence tags (ESTs) that have high similarity with known genes in the public database, which were involved in signal transduction, transcriptional regulation, cellular molecular dynamics, cytoskeleton, metabolism and oxidation-reduction. In addition, one novel EST that has no similarity with known genes in the public database was obtained. Eight ESTs, TIMP1, NUCB1, OAZ1, CXXC5, CAPNS2, ATP5A1, Z and RPL5, were further examined for the reproducibility of the SSH data by the real-time quantitative PCR. The results confirmed an increased expression of respective mRNA in ovarian tissues of polytocous goats compared with those of monotocous goats. The study has identified several genes (known or unknown) that may have effect on follicular development, ovulation and egg activation in goats.
