Abstract
We previously demonstrated antisense oligonucleotides (AS-ODNs) delivery system based on the complex formed with poly (dA) and schizophyllan, a type of β-1,3-glucan. This complex enables efficient intracellular delivery of AS-ODNs. In this communication, we investigated the cytoplasmic translocation of the complex itself and its mechanism of action on mRNA. As a result, we found that the complex moved into the cytoplasm while keeping its structure, and AS-ODN hybridized with the target mRNA. This result encourages pharmaceutical applications of the complex.
