Cell differentiation is a central process in development and in cancer growth and dissemination. OCT4 (POU5F1) and NANOG are essential for cell stemness and pluripotency; yet, the mechanisms that regulate their expression remain largely unknown. Repetitive elements account for almost half of the Human Genome; still, their role in gene regulation is poorly understood. Here, we show that the diox...

PURPOSE To unravel the role of interleukin (IL)-6 and insulin-like growth factor (IGF)-I receptor (IGFIR) in expressing stemness-related properties and to evaluate the prognostic values of pluripotent transcription factor OCT4/NANOG, and IGFIR in hepatocellular carcinoma (HCC). EXPERIMENTAL DESIGN Serum levels of IL6 were detected using ELISA assays (n = 120). The effects of IL6/IGFI on stemn...

سرطان های دستگاه گوارش جزء 10 سرطان شایع در جهان هستند که سالانه درصد بالایی از مرگ و میر را به خود اختصاص می دهند. با وجود اینکه در زمینه درمان سرطان پیشرفت های زیادی صورت گرفته اما به دلیل عود مجدد و مقاومت سلول های سرطانی در برابر پرتودرمانی و شیمی درمانی، مدیریت این بدخیمی ها همچنان چالش برانگیز می باشد. سلول های بنیادی سرطان، زیر جمعیت کوچکی از سلول های درون تومور بوده که مسئولیت حفظ و گست...

The genetic networks controlling stem cell identity are the focus of intense interest, due to their obvious therapeutic potential as well as exceptional relevance to models of early development. Genome-wide mapping of transcriptional networks in mouse embryonic stem cells (mESCs) reveals that many endogenous noncoding RNA molecules, including long noncoding RNAs (lncRNAs), may play a role in co...

PURPOSE To investigate the association of cancer stem-cell markers [octamer-binding transcription factor 4 (OCT4), sex determining region Y-box 2 (SOX2), and Nanog homebox (NANOG)] expression with clinicopathological properties and overall survival (OS) in operative rectal cancer (RC) patients receiving adjuvant therapy. MATERIALS AND METHODS 153 patients with primary RC receiving surgery wer...

AIM To identify and characterize cancer stem cells (CSCs) in moderately differentiated lip squamous cell carcinoma (MDLSCC). METHOD MDLSCC samples underwent 3,3-diaminobenzidine (DAB) immunohistochemical (IHC) staining for squamous cell carcinoma marker EMA, CSC marker CD44 and embryonic stem cell markers NANOG, octamer-binding transcription factor 4 (OCT4), spalt-like transcription factor 4 ...

The transcriptional activators Oct4, Sox2, and Nanog cooperate with a wide array of cofactors to orchestrate an embryonic stem (ES) cell-specific gene expression program that forms the molecular basis of pluripotency. Here, we report using an unbiased in vitro transcription-biochemical complementation assay to discover a multisubunit stem cell coactivator complex (SCC) that is selectively requi...

BACKGROUND Activation of inflammation-mediated endometrial injury is suggested to play a decisive role in pathogenesis of intrauterine adhesion (IUA). The stem cell theory of endometrial diseases has been given a hotspot, in that human endometrial stem cells have been isolated from the endometrium. Three transcription factors that play key roles in maintaining pluripotency and self-renewal in s...

Induced pluripotent stem (iPS) cells are a type of pluripotent stem cell artificially derived from non-pluripotent cells by overexpressing the transcription factors Oct4, Sox2, Klf4 and Nanog. These transcription factors play a pivotal role in stem cells; however, the function of these factors are not fully characterized. In this study, we analyzed Oct4, Sox2, Klf4 and Nanog in ten different sp...

تکثیر بی رویه و خارج از کنترل سلولها در یک موجود پر سلولی، اصلی ترین ویژگی سرطان می باشد. سلولهایی که به این مرحله می رسند خصوصیات جالبی از خود نشان می دهند ازجمله مشابهت بسیار بالای آنها به سلولهای بنیادی مثلاً از لحاظ بیان پروفایل ژنی و نیز نامیرایی و قابلیت انجام تقسیمات نامحدود. در یک تومور شکل گرفته، تعداد محدودی از سلولهای توموری این خصوصیات را نشان می دهند. این سلولها بنا بر مشابهت ذکر شد...
