The initial asRNAs discovered were in prokaryotes including plasmids, bacteriophage and bacteria. Dev Biol 2: Due to the complexity of the wntisentido asRNAs, they are currently considered as less druggable targets.


Nucleobases Nucleosides Nucleotides Deoxynucleotides. For example, the synthesized protein used in the enzyme replacement therapies often cannot mimic the whole function of the endogenous protein.

During computational searches, the encoding regions are excluded. The idea of asRNAs as drug targets started in when Zamecnik and Anntisentido found an antisense oligonucleotide to the viral RNA of Rous scarcoma virus that was capable of inhibiting viral replication and protein synthesis.

Another way of affecting transcription co-transcriptionally is by blocking splicing. Trends Cell Biol 17 3: Biosci Rep 25 5—6: Nucleic Acids Res 32 Web Server issue: Secondly, off target toxicity also represents a big problem. Biotechnol Lett 28 They often show high degree or complete complementarity with the target gene.

Int J Parasitol 36 7: Mol Microbiol 6 Because of these properties antisentio trans-acting asRNAs, they form less stable complexes with their targeting transcripts and sometimes require aids from RNA chaperone protein such as Hfq to exert their functions.


In addition to computational searches and microarrays, some asRNAs were discovered by sequencing cDNA clones as well as mapping promoter elements. J Virol 80 In bacteriophage P22, the asRNA sar helps regulate between lytic and lysogenic cycle by control the expression of Ant. Handb Exp Pharmacol Due to the nature of drug development, it is always easier to have drugs functioning as downregulators or inhibitors. Dev Biol 1: Mipomersen was developed to manage the level of low-density lipoprotein-cholesterol LDL in patients with homozygous familial hypercholesterolemia HoFHwhich is a rare autosomal dominant genetic condition.
