Translation inhibition by phosphorothioate oligodeoxynucleotides in cell-free systems
Abstract:
A detailed comparison was made of the concentration dependence of translation inhibition by phosphorothioate and phosphodiester oligodeoxynucleotides of the same anti-beta-globin sequence in cell-free systems using beta-globin mRNA and unrelated mRNAs as controls. The results confirm that at low concentrations the phosphorothioate oligomer is more potent as an antisense compound, while at higher concentration (greater than 4 microM) it exhibits more nonspecific inhibition than the phosphodiester oligomer for RNase H-mediated translation inhibition.

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...

Initiation of Translation
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...
