Self-Assembled Aptamer-Derived PROTAC Enables Efficient Cellular Internalization for Intracellular Sclerostin Degradation and Triple-Negative Breast Cancer Therapy.
Comprising an aptamer for protein of interest (POI) recognition, a linker, and an E3 ligand, aptamer-derived PROTAC enables precise intracellular POI degradation via ubiquitin-proteasome system. Due to hydrophilic polyanionic backbone, their efficacy was fundamentally constrained by inefficient cellular internalization...
