Gene silencing is a general term describing epigenetic processes of gene regulation. The term gene silencing is generally used to describe the 'switching off' of a gene by a mechanism other than genetic mutation. That is, a gene which would be expressed (turned on) under normal circumstances, is switched off by machinery in the cell. Genes are regulated at either the transcriptional or post-transcriptional level. Transcriptional gene silencing is the result of histone modifications, creating an environment of heterochromatin around a gene that makes it inaccessible to transcriptional machinery (RNA polymerase, transcription factors, etc.). Post-transcriptional gene silencing is the result of mRNA of a particular gene being destroyed. The destruction of the mRNA prevents translation to form an active gene product (in most cases, a protein). A common mechanism of post-transcriptional gene silencing is RNAi. Both transcriptional and post-transcriptional gene silencing are used to regulate endogenous genes. This book presents the latest research in this important field.
The principles behind RNAi are just being uncovered, but this laboratory technique has been applied effectively in a wide variety of animal and plant species.
This book describes the way small RNA is produced and acts to silence genes, its likely origins in defence against viruses, and also its potential to improve plants.
This book focuses on an emerging, central issue in molecular genetics and the development of eukaryotes: the control of gene expression by small species of RNA.
Unlike journal articles, Gene Silencing by RNA Interference: Technology and Application combines essential background to the RNAi field with practical techniques designed by r
In RNA Silencing: Methods and Protocols, many of the most notable and distinguished researchers in the field describe in step-by-step detail their best methods for the design, preparation, and use of RNAs to reduce gene expression in cells ...
In recent years several different gene silencing phenomena have been discovered in plants. The book summarizes the most recent data on gene silencing phenomena such as trans-, inactivation, paramutation and co-suppression.
RNAi technology is used for large-scale screens that systematically shut down each gene in the cell, which can help identify the components necessary for a particular cellular process or an event such as cell division.
