Moreover, YAP1 mRNA levels were significantly decreased in PCa patients irrespective of lymph node metastasis (N0, p = 7.45 × 10−10; n = 345 and N1, p = −1.36 × 10−9; n = 79) as compared to normal controls (n = 52; Figure 2C). This evidence concerns the gene YAP1 and metastatic malignant neoplasm in the lymph nodes.
