|Short hairpin RNAs (shRNAs) are a sequence of RNAs that makes a tight hairpin turn and are transcribed by RNA polymerase Ⅲ. It uses a vector introduced into cells and utilizes the U6 promoter to ensure that the shRNA is always expressed and can be cleaved by the cellular machinery into siRNA, which is then bound to the RISC silencing gene expression via RNAi (Brummelkamp et al., 2002; Lee et al., 2002; Miyagishi and Tiara, 2002; [Paddison, et al. 2002; Paul et al., 2002; Sui et al., 2002; Cao et al, 2005; Harper et al., 2005; McIntyre and Fanning, 2006).]
||A short hairpin RNA (shRNA) is a sequence of RNA that makes a tight hairpin turn that can be used to silence gene expression via RNA interference. shRNA uses a vector introduced into cells and utilizes the U6 promoter to ensure that the shRNA is always expressed. This vector is usually passed on to daughter cells, allowing the gene silencing to be inherited. The shRNA hairpin structure is cleaved by the cellular machinery into siRNA, which is then bound to the RNA-induced silencing complex (RISC).
