WebNov 20, 2009 · This smaller “core” cHS4 element provides enhancer blocking activity and reduces position effects. However, the cHS4 core sequences alone do not insulate viral vectors effectively. Two copies of the core, while effective in plasmid based systems, are unstable in viral vectors. WebAug 28, 2007 · The cHS4 insulator has been shown to protect against transgene silencing by recruiting chromatin remodeling activities via USF1/2 ( 13 ). To evaluate the contribution of USF in protecting a transgene against TPE, we knocked down USF1 expression using five RNAi-expressing vectors against this protein ( 13 ).
WebDec 22, 2012 · Chicken hypersensitive site-4 (cHS4) is one of the best-characterized vertebrate DNA insulators. Its barrier activity protects against position effects and enhances transgene expression. (Arumugam et al. 2007 ). A fragment of 250 bp (the core element) within cHS4 performs most of the insulating activity of the cHS4 insulator (Hanawa et al. … WebOct 26, 2012 · The 5′-HS4 chicken β-globin (cHS4) insulator, a 1.2-kb sequence located at the 5′ end of the chicken β-globin domain, possesses both enhancer- and barrier-blocking effects, the latter which are coupled …
