ADAMTS18 and nasopharyngeal carcinoma: Jin, H et al. [14], validated the finding that the ADAMTS18 gene is frequently hypermethylated in a variety of tumor tissues, including oesophageal squamous cell carcinoma (24/46, 52%), nasopharyngeal carcinoma (30/43, 70%), hepatocellular carcinoma (6/20, 30%), breast carcinoma (5/21, 24%), cervical carcinoma (5/8, 63%) and other carcinomas.
