摘要: As a principal extracellular iron storage molecule, ferritin plays an important role in the iron-withholding strategy of innate immunity and detoxification system. In this study, we cloned and characterized another ferritin from Venerupis philippinarum (designated as VpFer2), in addition to one previously reported (VpFer1). VpFer2 possessed all the conserved features critical for the fundamental structure and function of ferritin H subunit. VpFer1 and VpFer2 mRNA were both found to be most abundantly expressed in hepatopancreas. Vibrio challenge could significantly up-regulate the mRNA expression of VpFers, and VpFer2 showed more sensitive to Vibrio anguillarum infection. For heavy metals exposure, the expression level of VpFer1 was significantly induced by Cd at 48 h, but kept relatively constant after exposure to Cu. With regards to VpFer2, the expression level dropped significantly at 24 h, then began to increase to the peak value at 48 h under Cd exposure, while Cu exposure constantly depressed the expression level of VpFer2 throughout the time course. Similarly, VpFer2 seemed to be more sensitive to heavy metals exposure than VpFer1 as its mRNA level changed by higher magnitudes. All these results suggested that VpFers may be important proteins involved in host immune defense and heavy metals detoxification. The diverse expression patterns of VpFers demonstrated that VpFer2 was an early and sensitive responder to environmental stress in V. philippinarum. (C) 2013 Published by Elsevier Ltd.
