Gene silencing can occur through various mechanisms, one of which is post-transcriptional gene silencing (PTGS). In post-transcriptional gene silencing, transcription of the target locus is not affected, but the RNA half-life is decreased. The mechanisms by which PTGS occurs are not yet clear. Exogenous dsRNA has been shown to act as a potent inducer of PTGS in nematodes, … As with the epigenetic and transcriptional stages of processing, this post-transcriptional step can also be regulated to control gene expression in the cell.
