Figure 3From: Identification and characterization of microRNA in the lung tissue of pigs with different susceptibilities to PCV2 infectionChanges in the expression of miR-122 in the different tissues from LW (A) and YL (B) pigs after PCV2 infection. The y-axis indicates the fold changes in normalized expression. SEs from the mean are labeled on the bar using vertical lines. * and ** indicate significance at the P value threshold levels of 0.05 and 0.01, respectively.Back to article page
