How does rna interference function
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is a conserved biological response to double-stranded RNA that mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes. This natural mechanism … See more Endogenous triggers of RNAi pathway include foreign DNA or double-stranded RNA (dsRNA) of viral origin, aberrant transcripts from repetitive sequences in the genome such as transposons, and pre-microRNA (miRNA). In … See more A simplified model for the RNAi pathway is based on two steps, each involving ribonuclease enzyme. In the first step, the trigger RNA (either dsRNA or miRNA primary transcript) is processed into an short, interfering RNA … See more RNAi can be triggered experimentally by exogenous introduction of dsRNA or constructs which express shRNAs. The high degrees of … See more WebApr 13, 2024 · Cyclin-dependent kinase 2 (Cdc2) is involved in the metabolic pathways of the cell cycle and plays essential roles in the regulation of cell proliferation in eukaryotic cells. Previous research predicted that Cdc2 is involved in regulating sexual reproduction in male oriental river prawns (Machrobrachium nipponense). In the present study, we investigated …
