CAPZA1 and infection: In 3 independent western blot analyses (P<0.05), as shown in (Fig 4), compared with the H1N1pdm09 infection, the down- or up-regulated proteins of CAPZA1 (33KDa), OAT (49KDa), PCBP1 (37KDa), EIF5A (18KDa), PAFAH1B2 (26KDa) in H7N9 infection were consistent with the 2-D DIGE results.
