Fig. 6From: Molecular identification and functional characterization of IRF4 from common carp (Cyprinus carpio. L) in immune response: a negative regulator in the IFN and NF-κB signalling pathwaysExpression levels of ccIRF4 in the HKLs upon different stimulation. The cells were collected at 0 (as control), 3, 6, 12 and 24 h post-infection for RNA extraction and real-time PCR analysis. Expression was normalized using the 40S ribosomal protein S11 (n = 3, mean ± SD, *P < 0.05)Back to article page
