In addition, our real-time PCR and Western blot results revealed that the mRNA and protein expression levels of stemness-related markers, including ABCG2, NANOG, OCT4 and SOX2, were significantly increased in TRIP6-transduced ZR-75-30 and MDA-MB-231 cells, and conversely downregulated in TRIP6-silenced breast cancer cells (Fig. 3b). The gene discussed is NANOG; the disease is breast carcinoma.
