ZBTB7A and nasopharyngeal carcinoma: To elucidate mechanisms by which ZBTB7A could maintain NPC tumorigenicity, 1501 differentially expressed lncRNAs and 1276 messenger RNAs (mRNAs) were identified by microarray-based screening comparing cells stably transfected with a short hairpin RNA (shRNA) targeting ZBTB7A with cells stably transfected with empty vector.
