Abstract:
Silent partner: In a recent publication, Gunderson and co-workers described an approach to recruit the abundant U1 snRNP, a splicing subparticle, to the last exon of a pre-mRNA, in a sequence-specific manner. This mediates interaction of the U1-70K protein subunit with poly(A) polymerase, thus blocking polyadenylation and inducing pre-mRNA degradation. This novel promising strategy expands the repertoire of gene-silencing concepts.

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...
