Gene expression studies in nasopharyngeal carcinoma (NPC) TW01 cells found that CDKN1A/p21, INCA1 (Cyclin A1 interacting protein 1), LATS2, and BIRC (baculoviral inhibitors of apoptosis repeat-containing) are up-regulated, and CDK2 (cyclin-dependent kinase 2), Cyclin A1, TP53, BAX (bcl-2-associated X protein), and BCL2 (B-cell CLL/lymphoma 2) are down-regulated by miR-372. The gene discussed is CDKN1A; the disease is nasopharyngeal carcinoma.
