RRM2 and nasopharyngeal carcinoma: To explore the roles of transcriptional and known markers of EMT in NPC metastasis, we generated a special gene microarray containing these elements to screen potential EMT-related genes on CNE2-PMSCV-RRM2-c2orf48 cells and paired control CNE2-PMSCV-vector cells, and the microarray data have been deposited in the Gene Expression Omnibus under accession number GSE100193.
