Figure 2: Knockdown of HOTAIR decreases melanoma A375 cell motility. (a) qRT-PCR analysis was performed to examine HOTAIR RNA levels in A375 cells transfected with siControl, siHOTAIR I, or siHOTAIR II. (b) Wounds were introduced by scratching confluent monolayers of A375 cells transfected with siControl, siHOTAIR I, or siHOTAIR II. Migration was monitored by light microscopy at 0 hours and 24 hours (upper panel). The widths of the gaps from 3 experiments were measured and the results are presented in a bar graph (lower panel). * .
