Quantitative real-time PCR analysis of tight junction genes in Schwann cells treated with MMPs. (A) MMP7 mRNA expression in Schwann cells transfected with MMP7 siRNA. (B) MMP9 mRNA expression in Schwann cells transfected with MMP9 siRNA. (C–E) The mRNA expression levels of (C) CLDN1, (D) CLDN10, and (E) CLDN22 in Schwann cells transfected with MMP7 siRNA. (F–H) The mRNA expression levels of (F) CLDN1, (G) CLDN10, and (H) CLDN22 in Schwann cells transfected with MMP9 siRNA. The expression levels of tight junction genes were expressed as relative abundance of target genes normalized to MRPL10 with respect to control. Numerical results were shown as mean (SD). ∗Statistically different from control (n = 3, paired t-test, P < 0.05).
