The objective of this study was to assess the effects of an upstream estrogen response element (ERE) on exogenous p53 tumor suppressor gene with a codon 72 polymorphism about which there have been controversial reports in relation to cancer risk. The p53 gene (bases 166-1143 from start codon) with the codon 72 polymorphism, inserted into the pIRES-hrGFP II plasmid with or without upstream ERE, ...
The consensus oestrogen response element (ERE) contains two inverted copies of an AGGTCA consensus hexameric half-site, spaced by three base pairs. It differs from many other hormone response elements, such as consensus thyroid (TREp) and retinoic acid (DR-5 RARE) response elements, only in the relative spacing and orientation of these sequences. In the present study we report values for cooper...
The effects of 17-β-estradiol in osteoblasts are primarily mediated by the nuclear transcription factors, estrogen receptor (ER)α and ERβ. ERs function through three general modes of action: DNA-binding dependent through estrogen response elements (EREs; designated nuclear ERE signaling); nuclear signaling via protein-protein interactions to other transcription factors (nuclear non-ERE signalin...
Entity and relation extraction (ERE) is a core task in information extraction. This has always faced the overlap problem. It was found that heterogeneous graph attention networks could enhance semantic analysis fusion between entities relations to improve ERE performance our previous work. In this paper, an entity network (ERHGA) proposed for joint ERE. A with gate mechanism constructed contain...
We present in this paper high signal-to-noise long-slit optical spectra of the Extended Red Emission (ERE) in the “Red Rectangle” (RR) nebula. These spectra, obtained at different positions in the nebula, reveal an extremely complex emission pattern on top of the broad ERE continuum. It is well known that three features converge at large distance from the central object, in wavelength and profi...
The effect of temperature in the range of 0–150 8C was studied for homoionic montmorillonite clays with Na and Csqq compensating ions in low hydration states. Both static and dynamic information concerning the interlayer ions and water moleculeswas obtained by Monte Carlo and molecular dynamics. Principal structural changes were limited to the water phase, markeddifference was o...
تکرارهای ga در پروموتر ژن ها، موتیفهایی هستند که با ساختارهای تنظیمی g4 چهارتایی، هم پوشانی دارند و در تشکیلات نوکلئوزوم درگیر هستند.قبلا پروموتر مرکزی ژن های کدکننده پروتئین را که دارای مقادیر زیادی تکرارهای ga هستند شناسایی شده است. ضرورت عملکرد این تکرارها با تحقیق بر روی ژن sox5، که در فرآیندهای تکاملی نقش دارد، مشخص شد. در این مطالعه عملکرد str پروموتر مرکزی ژن gabra3، که گیرنده مهمترین نو...
