Genome-wide expression analysis reveals differential expression of Cdk2 and p57 in TECs isolated from transgenic rat ( PKD2 (1–703)). (A). List of cell cycle-related genes examined by microarray analysis. The (*) denotes statistical significance after Bonferroni correction. (B). Each data point on the volcano plot stands for one gene. The cutoff of p-value after Bonferroni correction is shown by the red line. Only the two significantly differentially expressed genes are labeled with their gene symbol.
