Optimized nano-micelles can induce efficient genome editing in the mouse brain Mar 12 2021 The research group of Deputy Principal Research Scientist Dr. Satoshi Uchida (Associate Professor, Kyoto Prefectural University of Medicine) at the Innovation Center of NanoMedicine (Director General: Prof. Kazunori Kataoka, Location: Kawasaki-Japan, Abbreviation: iCONM) reported that optimized nano-micelles can induce efficient genome editing in the mouse brain. The 2020 Chemistry Nobel Prize-winning technology CRISPR/Cas9 holds great promise for treating various diseases such as congenital disorders and viral infections, by correcting the disease-specific genomic sequences. This technology attracted increasing attention in the last decade as it allows easy targeting of genomic sequences with high precision and low level of undesired off-target gene editing. However, safe and efficient delivery of the Cas9 DNA cutting enzyme and guide RNA (gRNA), which is a short piece of RNA that guides Cas9 to its genomic targets, remains an obstacle.
