  • Title: Activation of extracellular signal-regulated kinase in MDBK cells infected with bovine viral diarrhea virus.
    Author: Yamane D, Zahoor MA, Mohamed YM, Azab W, Kato K, Tohya Y, Akashi H.
    Journal: Arch Virol; 2009; 154(9):1499-503. PubMed ID: 19609634.
    Abstract:
    Our efforts to identify the cellular signaling cascades triggered by bovine viral diarrhea virus (BVDV) infection in MDBK cells revealed marked activation of extracellular signal-regulated kinase 1/2 (ERK). Enhanced phosphorylation of ERK was detected following infection with cytopathogenic (cp) BVDV, but not with noncytopathogenic BVDV. It appears that cp BVDV-induced ERK phosphorylation is caused by oxidative stress, because ERK phosphorylation was inducible by treatment with hydrogen peroxide or serum deprivation and was attenuated by addition of antioxidants. These results indicate that BVDV infection influences the ERK signaling pathway via oxidative stress, depending on the biotype.
