فاکتورهای شوک حرارتی (Heat Shock Factors)، نقش مهمی در پاسخ به تنش‌های زیستی و غیرزیستی در یوکاریوت‌ها ایفا می‌نمایند. هدف از اجرای این تحقیق، شناسایی ژن‌های فاکتور رونویسی AlHSF در گیاه هالوفیت آلوروپوس لیتورالیس (Aeluropus littoralis) می‌باشد. بدین منظور شناسایی و تعیین مشخصه‌سازی ژن‌ها، ساختار ژنی، آنالیز موتیف‌های پروتئینی و روابط فیلوژنتیکی خانواده ژنی AlHSF مدنظ...
The pluripotency-associated transcription factor SOX2 is essential during mammalian embryogenesis and later in life, but SOX2 expression can also be highly detrimental. Over the past 10 years, SOX2 has been shown to be expressed in at least 25 different cancers. This review provides a comprehensive overview of the roles of SOX2 in cancer and focuses on two broad topics. The first delves into th...
برازینواستروئیدها (Brassinosteroids) هورمونهای استروئیدی گیاهی هستند که کارکرد متنوعی در تنظیم طیف وسیعی از فرآیند‌های رشد و نموی و همچنین پاسخ به تنش‌های زیستی و غیرزیستی ایفا می‌کنند. عوامل رونویسی BES1 در تنظیم بیان ژن‌های واکنش‌گر به برازینواستروئید نقش حیاتی دارند. تکمیل توالی‌یابی ژنوم انگور محققان را قادر ساخته است که خانواده‌های ژنی را در گستره ژنوم انگور شناسایی و مطالعه کنند. لذا در ا...
BACKGROUND SOX2 is an embryonic developmental transcription factor, which is important in the development of the respiratory tract. SOX2 overexpression is associated with aggressive disease in several tumor types. However, SOX2 overexpression and gene amplification associates with favorable outcome in lung squamous cell carcinomas (SCC) and dissimilar results have been reported in lung adenocar...
Despite advances in detection and therapy, castration-resistant prostate cancer continues to be a major clinical problem. The aberrant activity of stem cell pathways, and their regulation by the Androgen Receptor (AR), has the potential to provide insight into novel mechanisms and pathways to prevent and treat advanced, castrate-resistant prostate cancers. To this end, we investigated the role ...
Sox2 plays critical roles in cell fate specification during development and in stem cell formation; however, its role in postmitotic cells is largely unknown. Sox2 is highly expressed in supporting cells (SCs) of the postnatal mammalian auditory sensory epithelium, which unlike non-mammalian vertebrates remains quiescent even after sensory hair cell damage. Here, we induced the ablation of Sox2...
PURPOSE The role of SRY-Box 2 (SOX2) in anophthalmia/microphthalmia (A/M) is well known, with 10%-20% of A/M explained by mutations in SOX2. SOX2 plays roles in the development of both the posterior and anterior segment structures of the eye and relies on interactions with tissue-specific partner proteins to execute its function, raising the possibility that SOX2 mutations may result in varying...
The transcription factor SOX2, associated with amongst others OCT3/4, is essential for maintenance of pluripotency and self-renewal of embryonic stem cells. SOX2 is highly expressed in embryonal carcinoma (EC), the stem cell component of malignant nonseminomatous germ cell tumors, referred to as germ cell cancer (GCC). In fact, OCT3/4 together with SOX2 is an informative diagnostic tool for EC ...
The SRY-related HMG-box family of transcription factors member SOX2 regulates stemness and pluripotency in embryonic stem cells and plays important roles during early embryogenesis. More recently, SOX2 expression was documented in several tumor types including ovarian carcinoma, suggesting an involvement of SOX2 in regulation of cancer stem cells (CSC). Intriguingly, however, studies exploring ...
SOX2 is a gene that encodes for a transcription factor belonging to the SOX gene family and contains a high-mobility group (HMG) domain, which permits highly specific DNA binding. Consequently, SOX2 functions as an activator or suppressor of gene transcription. SOX2 has been described as an essential embryonic stem cell gene and moreover, a necessary factor for induced cellular reprogramming. S...
