Antisense-RNA regulation and RNA interference.
For a long time, RNA has been merely regarded as a molecule that can either function as a messenger (mRNA) or as part of the translational machinery (tRNA, rRNA). Meanwhile, it became clear that RNAs are versatile molecules that do not only play key roles in many important biological processes like splicing, editing, protein export and others, but can also--like enzymes--act catalytically. Two ...
متن کاملTargeted nuclear antisense RNA mimics natural antisense-induced degradation of polyoma virus early RNA.
We describe a general antisense strategy to inhibit target gene expression. The substitution of a cis-acting ribozyme for a polyadenylylation signal in an antisense expression vector results in the nuclear retention of RNAs and the efficient degradation of their targets. We demonstrate the utility of this system in polyoma virus, where early-strand RNA levels are downregulated in the nucleus by...
متن کاملRNA-RNA Interaction Prediction and Antisense RNA Target Search
Recent studies demonstrating the existence of special noncoding "antisense" RNAs used in post transcriptional gene regulation have received considerable attention. These RNAs are synthesized naturally to control gene expression in C. elegans, Drosophila, and other organisms; they are known to regulate plasmid copy numbers in E. coli as well. Small RNAs have also been artificially constructed to...
متن کاملبیان LncRNA HOX transcript antisense RNA در بیماران تازه تشخیص داده شده لوسمی لنفوبلاستیک حاد
چکیده سابقه و هدف لوسمی حاد لنفوبلاستی، شایع‌ترین بدخیمی دوران کودکی می‌باشد. سالانه در کل دنیا به ازای هر 100 هزار نفر،1 تا 7/4 نفر به این بیماری مبتلا می‌شوند. Long non-coding RNA ها (lncRNAs)، گروهی از RNAهای غیرکدشونده هستند که در فرآیندهای زیستی از جمله تغییرات اپی‌ژنتیکی، کنترل رونویسی و ترجمه نقش دارند. استفاده از lncRNA های اختصاصی خونی و شناسایی عملکرد آن‌ها می‌تواند در شناخت بیشتر پا...
متن کاملRNA polymerase II synthesizes antisense RNA in Plasmodium falciparum.
The recent identification of antisense RNA in the transcriptomes of many eukaryotes has generated enormous interest. The presence of antisense RNA in Plasmodium falciparum, the causative agent of severe malaria, remains controversial. Elucidation of the mechanism of antisense RNA in P. falciparum synthesis is critical in order to demonstrate the origin and function of these transcripts. Therefo...
