Expression of FN1 is suppressed in macrophages after S. aureus infection. a The level of FN1 expression in macrophages after S. aureus infection was determined time-coursely by RT-PCR and the representative images are shown. b The relative densitometric quantification of above results is shown. The numbers ‘12598’ and ‘1221’ represent the S. aureus strains ATCC 12598 and SJC1221 (FnBP deficient), respectively. The fold change of each transcript was compared with untreated cells at each time point and was indicated. * P < 0.05; ** P < 0.01
