Abstract

Emerging evidences suggest that cancer stem cells (CSCs) are responsible for tumor growth, metastasis and treatment resistance. Nanog is one of the transcription factors that are essential for stem cellular physiology process. Previous studies reported that Nanog was detected in breast cancer and other solid tumors and indicated that it has oncogenic characteristics. However, expression feature of Nanog in breast cancer stem cells (BCSCs) enriched population and its biological function in BCSCs is poorly understood. In this study, CD44 + CD24- fraction sorting with Fluorescence Activated Cell Sorter and mammosphere culture were used for enriching BCSCs. We report here that Nanog was highly expressed in CSCs-enriched population from the breast cancer cells, as well as stemness-associated genes. In addition, we employed the lentivirus-mediated shRNA targeting Nanog to investigate function of Nanog in BCSCs. We found that targeted inhibition of Nanog could suppress proliferation and colony formation in breast cancer cells. Further studies showed that targeted inhibition of Nanog resulted in a decrease of BCSCs activities, including mammosphere formation, CD44 + CD24- proportion and expressions of stemness-associated genes. These d...Continue Reading
