Increasing drought tolerance, especially in rice, which is one of the most important crops in Asia, is necessary. Transcription factors are specific sequence DNA-binding proteins that are capable of activating or suppressing transcription. These proteins regulate gene expression levels by binding to cis regulatory elements in the promoter of target genes to control various biological processes ...

objective: hla-g is a nonclassical major histocompatibility complex antigen and is expressed as seven isoforms, including four membrane bound (hla-g1 to –g4) and three soluble (hla-g5 to –g7) forms. the pattern of selective expression of hla-g transcripts in tissues shows the existence of a tight transcriptional control on the gene expression. it has been revealed that cytokines including inter...

Background & Aims: Blood-brain barrier (BBB) breakdown and nitric oxide (NO) overproduction following cerebral ischemia-reperfusion extensively happens in the subcortical regions (core areas). Hence, we assessed the effects of NO inhibition by L-NAME on transcription of the transmembrane proteins claudin-3 and 12, with key role in BBB structure, at subcortical areas following cerebral ischemia-...

Despite some differences, Islamic-Iranianmanuscriptshave special common out-of-text and within-text structures. These structures were followed by authors, scribes and transcription centers during centuries when transcription tradition was dominant throughout the Islamic world. In this article, these common features were considered in detail. Some manuscript folios preserved in National Library ...

background: metabolic syndrome (mets) is a prevalent disorder in pediatric age groups, described by a combination of genetic and environmental factors. sterol regulatory element‑binding transcription factor 1 (srebf‑1) induces the expression of a family of genes involved in fatty acid synthesis. moreover, dysregulation of mir‑33b, which is located within the intron 17 of the srebf‑1 gene, disru...

Stem cells are undifferentiated biological cells that can differentiate into more specialized cells and divide (through mitosis) to produce more stem cells (self-renew). In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. Mesenchymal stem cells (MSCs) are ...

artemisia annua is an annual herb native to asia most probably china produce one of the most important sesquiterpene namely artemisinin which has antimalarial and anticancer activity. three transcription factors belonging to wrky family, two transcription factors belonging to myb family and two enzymes dbr2 and opr3 were isolated from a.  annua leaves and first inserted into pjet1.2 vector then...

The response to drought stress is a complicated process involving stress sensing, intracellular signaltransduction, and the execution of a cellular response. Transcription factors play important roles in the signaling pathways including abiotic stress. In the present study a rice NF-YA transcription factor gene was partially characterized following dehydration. Disrupting the gene via a T...
