PDCD5 and nasopharyngeal carcinoma: For example, in nasopharyngeal carcinoma, the negative correlation between miRNA-19a-3p and PDCD5 expression levels, miRNA-19a-3p targeting to suppress PDCD5 expression, miRNA-19a-3p levels correlated with N classification and clinical stage of nasopharyngeal carcinoma patients, and PDCD5 levels correlated with T classification, pathological grade, and clinical stage.
