Low miR-145 expression was arbitrarily defined as smaller than 0.75 (standardized by adjacent normal) and indicated in bold. Methylation (%) in tumor (T) and adjacent normal (N) was the average of percentages at six CpG sites. dMethylation was the difference between methylation in cancer and adjacent normal. Values >20 were considered to represent significantly higher methylation and shown in bold. p53 mutations are indicated with codon number and names of involved amino acids.
