«These particles, microRNA based SNAs, could also potentially be used for gene silencing in other cancers and diseases of genetic origin.»
The bits, called short interfering RNA, then associate with other enzymes to form a large complex that can silence certain genes and render the virus harmless.
Angelman syndrome, which causes learning difficulties, speech problems, seizures, jerky movements and an unusually happy disposition, results when a gene inherited from the mother in a particular area of chromosome 15 is mutated and the other copy of the gene, inherited from the father, is silenced.

McKay and Tsai turned off production of the gene's protein through a technique known as gene silencing, and in other cases they added extra protein to the cells.
To determine whether the reactivation of methylation - silenced genes by EGCG is a general phenomenon that also occurs in other cell lines, we studied the effects of EGCG treatment on the methylation status and mRNA levels of p16INK4a or RARβ in three other human cancer cell lines (Fig. 3C) ⇓.
The third PDR approach and the one that we intend using not only for MSV resistance but also for other viruses such as MRDV, is based on something called RNA - mediated gene silencing.
