Small transcriptional-activating rna
WebRNA activation (RNAa) is a lately discovered phenomenon that small double-stranded RNAs (dsRNAs) can activate specific gene expression by targeting complementary sequences on the gene promoter, and such dsRNA molecules are termed as small activating RNAs (saRNAs). 7 A previous study reported that a candidate saRNA, dsP53-285, can induce … Small activating RNAs (saRNAs) are small double-stranded RNAs (dsRNAs) that target gene promoters to induce transcriptional gene activation in a process known as RNA activation (RNAa). Small dsRNAs, such as small interfering RNAs (siRNAs) and microRNAs (miRNAs), are known to be the trigger of an evolutionarily conserved mechanism known as RNA interference (RNAi). RNAi invariably leads to gene silencing via remodeling of chromatin to thereby suppress transcription, …
