Figure 2B shows different levels of UBE2C protein expression in the prostatic tissues measured by immunohistochemistry staining. The immunohistochemical characteristics of UBE2C expression in the PCa tissues and the adjacent tissues were investigated using a paired Wilcoxon test, as displayed in Figure 2C. The paired Wilcoxon test shows that the UBE2C expression in PCa tissues was notably higher than in the adjacent tissues (p = 0.0002446). These results indicate that UBE2C is associated with tumorigenesis in PCa (p < 0.001, Figure 2C). This evidence concerns the gene UBE2C and posterior cortical atrophy.
