Table 3. The siRNA NOX4-1 group exhibited a highest silencing efficiency.

Group	NOX4 mRNA	Silencing rate (%)
siRNA NOX4-1	0.246 ± 0.033*#	75.79 ± 3.25
siRNA NOX4-2	0.467 ± 0.011*#&	33.87 ± 1.75
siRNA NOX4-3	0.492 ± 0.023*#&	31.15 ± 2.33
Negative control	0.816 ± 0.012	3.43 ± 1.24
Blank control	0.845 ± 0.042

Note: The data were analyzed by one-way ANOVA with Tukey's test; n = 3; * p < 0.05 vs. the negative control group; ^# p < 0.05 vs. the blank control group; ^& p < 0.05 vs. the siRNA NOX4-1 group; NOX4, NADPH oxidase 4.
