Molecular Cell Biology 5th ed. Because of the locus specific nature of asRNAs and evidences of changes in asRNA expression in many diseases, there have been attempts to design single stranded oligonucleotides, referred as antagoNATs, to inhibit asRNAs and ultimately to increase specific gene expression.

Translational Messenger precursor, heterogenous nuclear Transfer Ribosomal Transfer-messenger. AsRNAs can be involved in this level of gene regulation. Mipomersen was developed to manage the level of low-density lipoprotein-cholesterol LDL in patients with homozygous antisentiido hypercholesterolemia HoFHwhich is a rare autosomal dominant genetic condition. PLoS Genet 2 7: This anyisentido is relatively fast because both the targeting mRNA and its asRNA need to be present simultaneously in the same cell.

They may also have therapeutic applications. Annu Rev Plant Biol Because of these properties of 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. Drug Discov Today 10 3: Nat Struct Mol Biol 13 1: Nucleic Acids Res 33 Web Server issue: Nat Cell Biol 7 6: Curr Opin Mol Ther 7 2: As a regulatory element, asRNAs bear many advantages to be considered as a drug target.

“ARN antisentido” in English

In terms of epigenetic modification, cis-acting refers to the nature of these asRNAs that regulate epigenetic changes around the loci where they are transcribed. PLoS Biol 2 5: Sometimes, however, gene repression can be achieved by prematurely terminating or slowing down transcription process.

Because the regulatory mechanism of asRNAs are found to be species specific, asRNAs can also be classified by species. In terms of drug targets, this represents a huge advantage because only a low dosage is required for effectiveness. Despite the promises of asRNAs as drug targets or drug candidates, there are some challenges remained to be addressed [13].


Neste caso, os micro ARN poden funcionar como oncoxenes ou como supresores de tumores. Nat Immunol 7 6: Due to the nature of drug development, it is always easier to have drugs functioning as downregulators or inhibitors. Lastly, depending on the level of asRNA expression, different isoforms of the sense transcript can be produced.

Biotechnol Lett 28 Genes Dev 18 In contrast to cis-acting asRNAs, they display low degree of complementarity with the target gene but can be longer than cis-acting asRNAs.
