The discovery of environmental RNA interference (RNAi), in which gene expression is suppressed via feeding with double-stranded RNA (dsRNA) molecules, opened the door to the practical application of RNAi-based techniques in crop pest management. The western corn rootworm (WCR, Diabrotica virgifera virgifera) is one of the most devastating corn pests in North America. Interestingly, WCR displays...

RNA interference (RNAi) has advanced into clinical trials. In spite of the progress made in systemic RNAi delivery to the liver and solid tumors, delivery of RNAi to leukocytes remains challenging and less advanced. Manipulating leukocyte function with RNAi holds great promise for streamlining the drug discovery process by facilitating in vivo drug target validation and for facilitating the dev...

objective: e1a oncoprotein of adenovirus type 5 is a regulatory factor which controls transcription of other adenovirus genes. this protein promotes both viral genom replication and host cell transformation by altering the function of certain important cellular proteins such as p21 and rb. the aim of the present study was to constantly reduce the expression of e1a gene in hek 293 cell line by r...

RNA interference (RNAi), an effective technique for regulating or silencing specific genes, can be applied to treat various diseases. Multiple clinical trials using RNAi are ongoing, and molecular imaging can serve as a powerful tool in RNAi-based therapies. This brief review will highlight the current progress on in vivo imaging of RNAi delivery and silencing effects. Incorporation of suitable...

RNA interference (RNAi) is a widespread and widely exploited phenomenon. Here, we show that changing inositol 1,4,5-trisphosphate (IP3) signalling alters RNAi sensitivity in Caenorhabditis elegans. Reducing IP3 signalling enhances sensitivity to RNAi in a broad range of genes and tissues. Conversely up-regulating IP3 signalling decreases sensitivity. Tissue-specific rescue experiments suggest I...

Over the past years RNA interference (RNAi) has exploded as a new approach to manipulate gene expression in mammalian systems. More recently, RNAi has acquired interest as a potential therapeutic strategy. This review focuses on the potential therapeutic use of RNAi for metabolic diseases, the current understanding of RNAi biology, and how RNAi has been utilized to study the role of different g...

RNA interference (RNAi) is an ancient mechanism of gene suppression, whose machinery and biological functions are only partially understood. Intensive studies have focused on developing RNAi technologies for treating human diseases and for improving plant traits. Yet application of RNAi to improving the nutritional value of plants for human and animal nutrition, and development of the related R...

The RNA interference (RNAi) pathway is found in most eukaryotic lineages but curiously is absent in others, including that of Saccharomyces cerevisiae. We show that reconstituting RNAi in S. cerevisiae causes loss of a beneficial double-stranded RNA virus known as killer virus. Incompatibility between RNAi and killer viruses extends to other fungal species in that RNAi is absent in all species ...

RNA-mediated interference (RNAi) has emerged recently as one of the most powerful functional genomics tools. RNAi has been particularly effective in the nematode worm C. elegans where RNAi has been used to analyse the loss-of-function phenotypes of almost all predicted genes. In this review, we illustrate how RNAi has been used to analyse gene function in C. elegans as well as pointing to some ...
