Short-interfering RNAs as antivirals against rabies.
This study aimed to test in vitro a RNA-interference based antiviral approach for rabies with short-interfering RNAs (siRNAs) against rabies virus nucleoprotein mRNA. BHK-21 cells were infected with serial dilutions of PV rabies virus strain and transfected with a pool of three siRNAs. Direct immunofluorescence staining showed a 5-time decrease in virus titer when compared to a non-treated plat...
متن کاملMicro RNAs and Short-interfering RNAs in Plants
Gene silencing can occur either at the transcriptional level or post-transcriptional level or both. Many instances of sequence-specific silencing requires small RNAs that can be divided into two major classes: microRNAs (miRNAs) and short-interfering RNAs (siRNAs). miRNAs function in post-transcriptional gene silencing by guiding mRNA degradation or translational repression. Endogenous siRNAs a...
متن کاملConditional gene knock-down by CRE-dependent short interfering RNAs.
Short interfering RNAs (siRNAs) are short (21-23 nt) double-stranded RNAs that direct the sequence-specific degradation of corresponding mRNAs, resulting in suppression of gene activity. siRNAs are powerful tools for gene functional analysis in mammals. Chemically synthesized siRNAs permit transient gene repression but preclude inhibition of stable gene products as well as long-term phenotypic ...
متن کاملShort small-interfering RNAs produce interferon-α-mediated analgesia.
BACKGROUND There is increasing interest in RNA interference in pain research using the intrathecal route to deliver small-interfering RNA (siRNA). An interferon (IFN) response is a common side-effect of siRNA. However, the IFN response in the spinal cord after intrathecal administration of siRNA remains unknown. We hypothesized that high doses of siRNAs can elicit off-target analgesia via relea...
متن کاملCoupling Aptamers to Short Interfering RNAs as Therapeutics
RNA-based approaches are among the most promising strategies aimed at developing safer and more effective therapeutics. RNA therapeutics include small non-coding miRNAs, small interfering RNA, RNA aptamers and more recently, small activating RNAs. However, major barriers exist to the use of RNAs as therapeutics such as resistance to nucleases present in biological fluids, poor chemical stabilit...
