Combined analysis of AS events and expression profile in UC patients. A PCA plot of 4 UC versus 4 control expression profile using the top 2000 regulated genes as variables. B Scatterplot pairs of first three principal components for Percent Spliced In (PSI) values across 8 samples. The red triangles represent UC disease patients and the blue circle represent normal samples. C Venn diagram showed overlapped genes involved in expression regulation and AS regulation
