In a previous study, we used miRNA chip technology to examine the differentially expressed miRNAs in FOXO1-overexpressing NPC cells (Supplementary Fig. 2A, GEO Accession Number: GSE78742) and confirmed that miR-200b is a positive modulator of FOXO1 (Supplementary Fig. 2B). The gene discussed is FOXO1; the disease is nasopharyngeal carcinoma.
