The parathyroid hormone (PTH)/PTH-related peptide (PTHrP) receptor regulates extracellular calcium concentrations and is therefore important for mineral homeostasis. ROS 17/2.8 cells, a rat osteoblast-like osteosarcoma cell line, express the PTH/PTHrP receptor and provide a good model for examining the transcriptional regulation of its gene. The rat PTH/PTHrP receptor gene has two promoters, U1...

Stilbene synthase is a key enzyme for the production of the phytoalexin resveratrol. Some clones of Vitis sylvestris, a wild European grapevine species which is almost extinct, have been shown to accumulate more resveratrol in response to different forms of stress. In the current study, we asked whether the induction of stilbene synthase transcripts in Hoe29, one of the V. sylvestris clones wit...

Recording of identified neuronal network activity using genetically encoded calcium indicators (GECIs) requires labeling that is cell type-specific and bright enough for the detection of functional signals. However, specificity and strong expression are often not achievable using the same promoter. Here we present a combinatorial approach for targeted expression and single-cell-level quantifica...

objective: in an attempt to develop safer and more effective gene therapy approaches as a realistic treatment for various forms of cancer, researchers are increasingly using tumor-specific promoters (tsp) to drive the expression of the gene of interest and eradicate cancer cells. in this study, for the first time we introduce the oct-4 promoter as a cancer-specific promoter with a high efficacy...

فعالیت کاتالیزور از مهم ترین پارامترها در فرایندهای پلیمرشدن است. برای یک سامانه کاتالیزوریفعالیت ممکن است به شرایط پلیمرشدن از قبیل دما و فشار وابسته باشد. با این حال، برای شرایط ثابتپلیمرشدن، افزایش فعالیت به روش تغییر دما و فشار رضایت بخش نیست و صنعتگران مجبورند تا مقدارکاتالیزور در راکتور یا زمان انجام پلیمرشدن را افزایش دهند که این کار نیز از لحاظ اقتصادی مقرونبه صرفه نیست. در سال های اخیر...

background: recently, we have shown that peroxisomal protein expression was induced upon retinoic acid treatment in mouse embryonic stem cells during the process of neurogenesis. thus, characterization of the respective promoter could elucidate the molecular aspects of transcriptional regulation of this gene. methods: using the conventional software programs for promoter prediction, a putative ...

    Background and Aim: Annexins are a large family of calcium-phospholipid binding proteins which are distributed among nearly all eukaryotes. These proteins have been found in a wide range of fungi including ascomycetes, basidiomycetes and oomycetes. The aim of present study has been the investigation of cellular localization of ANXC3.1 in filamentous fungus Aspergillus niger (A. niger). The ...

Plants in temperate regions have a remarkable capacity for cold acclimation; that is, they acquire enhanced tolerance to freezing after exposure to low nonfreezing temperatures. CBF transcription factors play a critical role in this process. In Arabidopsis, CBF genes are rapidly induced following exposure to cold temperature, and the CBF factors in turn induce the expression of ;100 other genes...

The mitogen-activated protein kinase (MAPK) pathway plays a pivotal role in intracellular signaling, and this cascade may impinge on cAMP response elements (CREs) of target genes. Both the MAPK pathway and chromogranin A expression may be activated by cytosolic calcium influx, and calcium-dependent signals map onto the chromogranin A promoter proximal CRE. We therefore probed the role of the MA...

background in this study, we evaluated the prevalence of the most common mutations occurring in enhancer ii (enhii), basal core promoter (bcp), precore (pc), and core (c) regions of hepatitis b virus (hbv) genome. objectives we also investigated the correlation between hbv variants, their genotypes, and patients’ hbe antigen (hbeag: soluble shape of the capsid antigen) status patients and metho...
