RNA interference-mediated silencing of NANOG leads to reduced proliferation and self-renewal, cell cycle arrest and apoptosis in T-cell acute lymphoblastic leukemia cells via the p53 signaling pathway.

NANOG is critical for maintaining the self-renewal and proliferative properties of embryonic stem cells. Here we found that cultured T-cell acute lymphoblastic leukemia (T-ALL) cells, as well as human primary T-ALL cells, express a functional variant of NANOG. NANOG mRNA is derived predominantly from a retrogene locus termed NANOGP8. Furthermore, we showed that RNA interference-mediated NANOG knockdown inhibited cell proliferation, reduced self-renewal, promoted apoptosis and arrested the cell cycle through a p53-mediated pathway in leukemic cells. These findings demonstrate the oncogenic potential of this pluripotent gene in human T-ALL cells.
