Figure Lengend Snippet: Validation of the circRNAs identified in PBMCs of MS patients versus HCs. Expression levels in PBMCs of five upregulated and four downregulated circRNAs ( A ) and the corresponding cognate linear mRNAs ( B ) were measured by qPCR analysis. The levels of circRNAs and mRNAs were normalized to GAPDH mRNA levels. Data are the means and standard deviation (+SD) from at least three independent experiments. ** p < 0.01, *** p < 0.001.

Figure Lengend Snippet: Circular RNAs are deregulated in human abdominal aortic aneurysm (A) Volcano plot depicting downregulated (51, blue) and upregulated (40, red). Circular RNAs (circRNAs) in human elective human abdominal aortic aneurysm (eAAA, n = 11) vs . control (CTRL, n = 6) aorta specimens, as resulted by array experiments. Log2 fold change and -log10 p value are plotted on the x and y axes, respectively. IDs of circRNAs meant for a first round of validation are highlighted. Statistics: unpaired t test; p values <0.05 are considered significant.
