FIG 2.

Expression profiles of HDAC1 in tissues of healthy pigs and in porcine IPEC-J2 cells during porcine epidemic diarrhea virus infection. (A) Expression of HDAC1 in major tissues of clinically healthy pigs. Total RNA for qRT-PCR was from three different parts of the tested tissues of each pig. (B) Expression pattern of HDAC1 and viral genome copies IPEC-J2 cells during PEDV infection detected by qRT-PCR. (C) HDAC1 expression, by SDS-PAGE/Western blotting, in the IPEC-J2 cells infected with PEDV for 24 h. (D) Densitometric analysis of HDAC1 expression relative to β-actin, as shown in panel C. The data were shown as means ± SD from three independent experiments for panels B and D. *, P < 0.05; **, P < 0.01.
