Identification of postnatal development dependent genes and proteins in porcine epididymis

The epididymis is a highly regionalized tubular organ possesses vectorial functions of sperm concentration, maturation, transport, and storage. The epididymis-expressed genes and proteins are characterized by regional and developmental dependent pattern. However, a systematic and comprehensive insight into the postnatal development dependent changes in gene and protein expressions of porcine epididymis is still lacking. Here, we performed the integrative analysis of transcriptomic and proteomic profiles of epididymis of Duroc pigs at different postnatal development stages.
