Figure 4. BMP3 siRNA silencing promotes the migration of RA and AIA FLS. (A) The protein levels of MMP-3, MMP-9, and TIMP-1 in TNF-α–treated RA FLS transfected with BMP3 siRNA were analyzed using western blot. (B) The protein levels of MMP-3, MMP-9, and TIMP-1 in TNF-α–treated AIA FLS transfected with BMP3 siRNA were analyzed using western blot. (C) The mRNA levels of MMP-3, MMP-9, and TIMP-1 in TNF-α–treated RA FLS transfected with BMP3 siRNA were analyzed using qPCR. (D) The mRNA levels of MMP-3, MMP-9, and TIMP-1 in TNF-α–treated AIA FLS transfected with BMP3 siRNA were analyzed using qPCR. (E) TNF-α–treated AIA FLS were transfected with BMP3 siRNA, and their migration into the wound-healing site after 24 hours was photographed (original magnification, ×10). (F) TNF-α–treated AIA FLS were transfected with BMP3 siRNA, and their migration into the wound-healing site after 24 hours was photographed (original magnification, ×10). All values are expressed as the mean ± SD. ^*P < 0.05, ^**P < 0.01 vs RA group. ^#P < 0.05, ^##P < 0.01 vs NC-RNAi group.
