Inspired by my experiences working in research at an overseas biotech venture, I founded GenAhead Bio Inc. in 2018. GenAhead Bio adopts a unique dual-business structure, providing contract services for generating genetically modified cells using highly efficient CRISPR/Cas9 genome editing technology for researchers, while simultaneously pursuing a nucleic acid drug business aiming to develop nucleic acid drugs such as antisense oligonucleotides and siRNAs. Based on the emerging delivery system called Antibody-Nucleic acid Conjugate, where an antibody is covalently linked to a nucleic acid as a targeting ligand, we are conducting drug developmental research by delivering nucleic acids to the organs where antibodies accumulate. Our ultimate goal is to apply this technology to genome editing for gene modification in specific cell types. In this review, we will introduce some case studies of genome editing, including single nucleotide substitutions, as well as the delivery of siRNA to the skeletal muscle using anti-transferrin receptor (CD71) antibody and its therapeutic effects on muscular diseases.
