We found a strong positive correlation between p53 expression levels and the levels of both snoRNA U44 (Pearson Correlation = 0.64; R2 linear = 0.41; P = 0.02) and snoRNA U47 (Pearson Correlation = 0.69; R2 linear = 0.49; P = 0.01) in colorectal tumour samples (Figure 6A). This evidence concerns the gene TP53 and colorectal neoplasm.
