CASP7 and cancer: It was shown that the average levels of gene expression for CASP1 (p < 0.001), CASP2 (p < 0.001), CASP4 (p < 0.001), CASP5 (p < 0.001), CASP7 (p < 0.001), CASP8 (p < 0.001), CASP9 (p < 0.001), CASP10 (p < 0.001), and CASP14 (p < 0.001) were statistically significantly higher in patients without invasion of cancer cells into the fat tissue (n = 26) than in patients with the presence of cancer cells in the fat tissue (n = 3) (Figure 6A,B).
