Nanog

[Cell Reports] Investigators showed that hypoxia-inducible factor 1α (HIF-1α) is required for NANOG-mediated breast CSC enrichment.

[Science Advances] The authors examined the molecular mechanisms coordinating the naïve to primed transition by using inducible ESC to genetically eliminate all RAS proteins. They showed that differentiated RASKO ESCs remained trapped in an intermediate state of pluripotency with naïve-associated features.

[European Journal of Pharmacology] While (R)-crizotinib induced changes in morphologies or sizes of cells, (S)-crizotinib did not. Pretreatment with (R)-crizotinib suppressed the proliferation of cancer or CSC-like cells in vitro and tumor growth in vivo.

[Reproductive Toxicology] To explore the developmental toxicity of 2,2',4,4'-Tetrabromodiphenyl ether (BDE47), mouse ESCs, which are ideal models for testing the developmental toxicity of environmental contaminants in vitro, were exposed to BDE47 for 24 h or 48 h in this study.

[EMBO Journal] Investigators showed that the novel oncogene RASSF1C drove mesenchymal-to-amoeboid transition and stem cell attributes in breast cancer cells. Mechanistically, RASSF1C activated Rho/ROCK via SRC-mediated RhoGDI inhibition, resulting in generation of actomyosin contractility.

[Cells Tissues Organs] The authors analyzed cellular, molecular, and chromosomal alterations in Wharton’s jelly-derived MSCs during their in vitrosequential passages.
