Inhibition of class II MHC gene expression by anti-sense RNA in transgenic mice
1Department of Immunology, Kobe University School of Medicine, Japan.
Abstract:
We have established transgenic mice carrying the anti-sense DNA to the gene encoding beta chain of the class II major histocompatibility complex (I-A) molecule. The amount of I-A molecule on splenic B lymphocytes from the mice was reduced in the presence of a large amount of the exogenous anti-sense RNA. The amount of I-A beta chain RNA was selectively reduced and inversely correlated with the amount of anti-sense RNA in the spleens. These results suggest that the I-A beta chain RNA is rapidly degraded by duplex formation with the anti-sense RNA in splenic B cells from the transgenic mice.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
