Therefore, we tested the equality of variance of the signal distribution in the ROIs for ANO7 vs. dabB and ANO7 vs. PPIB, which was significantly different in the former (p = 0.0009 in benign/low-grade cancer and p = 0.0451 in high-grade cancer) but not in the latter (p = 0.2430 in benign/low-grade cancer and p = 0.7282 in high-grade cancer). This evidence concerns the gene PPIB and cancer.
