CRISPR has off-target effects that researchers have been ignoring

Off-target genome editing refers to nonspecific and unintended genetic modifications that can arise through the use of engineered nuclease technologies such as: clustered, regularly interspaced, short palindromic repeats (CRISPR)-Cas9, transcription activator-like effector nucleases (TALEN), meganucleases, and zinc finger nucleases (ZFN). These tools use different mechanisms to bind a predetermined sequence of DNA (“target”), which they cleave (or "cut"), cr… Webb22 aug. 2014 · This is true not just for hepatic and cardiovascular toxicity, but in general for all organ-linked ADRs. 12 Importantly, we have learnt to address mitigation of off-target effects and producing drugs with less pharmacological promiscuity, 13, 14 in particular concerning “antitargets”. 12, 14, 15 For example, preclinical assessment of cardiac ion … Webb18 juni 2014 · Numerous examples of shRNA off-target phenotypes related to inflammatory responses have been described (Kabilova et al., 2012).Major immunostimulatory triggers include dsRNA oligonucleotides longer than 29–30 bp and the presence of specific U-rich or G-rich sequences (Hornung et al., 2005).Although none … truck bed protection coatings
