Together with octamer-binding transcription factor 4 and Nanog, they co-operatively control gene expression in PSCs and maintain their pluripotency. Furthermore, Sox2 plays an essential role in somatic cell reprogram-ming, reversing the epigenetic configuration of differ-entiated cells back to a pluripotent embryonic state. In addition to its role in regulation of pluripotency, Sox2 is also a critical factor for directing the differentiation of PSCs to neural progenitors and for maintaining the properties of neural progenitor stem cells. Here, we review recent findings concerning the involvement of Sox2 in pluripotency, somatic cell reprogramming and neural differentiation as well as the molecular mecha-nisms underlying these roles.展开更多

Data Sources： The data used in this review were mainly published in English from 2000 to present obtained from PubMed. The search terms were ＂SOX2,＂ ＂cancer,＂ ＂tumor＂ or ＂CSCs.＂ Study Selection： Articles studying the mitochondria-related pathologic mechanism and treatment of glaucoma were selected and reviewed. Results： SOX2, a transcription factor that is the key in maintaining pluripotent properties of stem cells, is a member of SRV-related high-mobility group domain proteins. SOX2 participates in many biological processes, such as modulation of cell proliferation, regulation of cell death signaling, cell apoptosis, and most importantly, tumor formation and development. Although SOX2 has been implicated in the biology of various tumors and CSCs, the findings are highly controversial, and information regarding the underlying mechanism remains limited. Moreover, the mechanism by which SOX2 involved in carcinogenesis and tumor progression is rather unclear yet. Conclusions： Here, we review the important biological functions of SOX2 in different tumors and CSCs, and the function of SOX2 signaling in the pathobiology ofneoplasia, such as Wnt/β-catenin signaling pathway, Hippo signaling pathway, Survivin signaling pathway, P13K/Akt signaling pathway, and so on. Targeting towards SOX2 may be an effective therapeutic strategy for cancer therapy.展开更多
