NANOG and cancer: The network included five nodes grouping transcription factors not only involved in cancer, but also in stemness (e.g., NANOG, LEF1), in neural differentiation (e.g., FOXA2/3, NKXs, NEUROG3) and in development (e.g., HOXs, PAXs) that could all be related to a node regrouping transcription factors of the hypoxia pathway.
