Proteomic Analysis of Differentially Expressed Proteins in Bovine Endometrium with Endometritis

Proteomic Analysis of Differentially Expressed Proteins in Bovine Endometrium with Endometritis

Endometritis is one of the primary reasons for reproductive failure. In order to investigate endometritis-associated marker proteins, proteomic analysis was performed on bovine endometrium with endometritis. In bovine endometritis, desmin, Ձ-actin-2, heat-shock protein (HSP) 27, peroxiredoxin-6, luteinizing hormone receptor isoform 1, collectin-43 precursor, deoxyribonuclease-I (DNase-I), and MHC class I heavy chain (MHC-Ih) were up-regulated. In contrast, transferrin, interleukin-2 precursor, hemoglobin Ղ subunit, and potassium channel tetramerisation domain- containing 11 (KCTD11) were down-regulated in comparison to normal endometrium. The proteomic results were validated by semiquantitative-PCR and immunoblot analysis. The mRNA levels of desmin, transferrin, Ձ-actin-2, HSP27, KCTD11, and MHC-Ih were up-regulated by over 1.5-fold, and showed a pattern similar to their proteomic profiles. Desmin and Ձ-actin-2 protein showed positive correlations between proteomic analysis and immunoblot analysis. These results suggest that desmin and Ձ-actin-2 may play important roles in endometritis-related function, and could be useful markers for the diagnosis of bovine endometritis.
