In considering both tumor and normal samples, miR-34a was inversely correlated with NOTCH1 (r = −0.563, P = 0.001; Figure 5A), SLUG (r = −0.374, P = 0.009; Figure 5B), ZEB1 (r = −0.505, P = 0.001; Figure 5C), and ZEB2 (r = −0.317, P = 0.028; Figure 5D) expressions. This evidence concerns the gene ZEB1 and neoplasm.
