Figure 2From: Pharmacological studies of the mechanism and function of interleukin-1β-induced miRNA-146a expression in primary human airway smooth muscleIL-1β-induced a time- and concentration-dependent increase in primary miR-146a expression. HASM cells were exposed to either vehicle control or 1 ng/ml IL-1β for the indicated time or to the indicated IL-1β concentration for 24 h. The time- (A) and concentration- (B) dependent expression of primary miR-146a was determined by qRT-PCR. The results are expressed as the mean ± SEM of four independent experiments where * p < 0.05 versus time-matched controls.Back to article page
