To investigate the potential effects of Vaccaria segetalis, we employed the proteomic approach on the dairy cow mammary gland epithelial cells (DCMECs). A total of 35 differentially expressed nuclear proteins were visualized by 2-DE and silver nitrate staining. Of these, five proteins also displayed significant expression changes upon treatment of the water decoction from Vaccaria segetalis, and such alterations were further confirmed by RT-PCR. Together, at both the mRNA and protein levels, the water decoction from Vaccaria segetalis increased the expression of proteins ethylmalonic encephalopathy 1 (ETHE1), vesicle amine transport protein 1 homolog (VAT1), parkinson disease protein 7 homolog (Protein DJ-1), proteasome subunit alpha type-2 (PSMA2) and SUMO-activating enzyme subunit 1 (SAE1). This study would enable a better understanding of the molecular mechanisms underlying this water decoction effects at the protein level.
