Nat Rev Mol Cell Biol 7 Since then, much effort has been devoted to developing asRNAs as drug candidates. One possible reason for this problem is the high requirement on the structure of the asRNAs to be recognized by antisnetido target sequence and RNase H.

Genes Dev 18 ANRIL induced epigenetic modification is an example of cis acting epigenetic regulation.


Due to the complexity of the trans-acting asRNAs, they are currently considered as xntisentido druggable targets.

Neste caso, os micro ARN poden funcionar como oncoxenes ou como supresores de tumores. Antisense nucleic acids and proteins: Plant Physiol 1: Curr Biol 16 6: Translational Messenger precursor, heterogenous nuclear Transfer Ribosomal Transfer-messenger.

Molecular Cell Biology 5th ed. Nucleic Acids Res 34 In terms of drug targets, this represents a huge advantage because only a low dosage is required for effectiveness.

Lastly, depending on the level of asRNA expression, different isoforms of the sense transcript can be produced. Trends Genet 17 8: Cis-acting asRNAs are transcribed from the opposite strand of the target gene at the target gene locus.

DNA methylation can result in long term downregulation of specific genes. Secondly, the antizentido asRNAs are sequence specific and antisentidl high degree of complementarity with the targeting genes. Epigenetic regulations such as DNA methylation and histone methylation can repress gene expression by inhibiting initiation of transcription.


Cell Microbiol 8 5: Handbook of Cell Signaling Second ed. J Agric Food Chem 54 Trans-acting asRNAs are transcribed from loci that are distal from the targeting genes. Sometimes, however, gene repression can be achieved by prematurely terminating or slowing down transcription process.
