Ribonuclease A-polymer conjugates via in situ growth for cancer treatment
Efficient delivery of therapeutic proteins is a critical aspect for protein-based cancer treatment. Herein, an in situ growth approach was employed to prepare ribonuclease A (RNase A)-polymer conjugates by incorporating a cationic polymer, poly(N,N'-dimethylamino-2-ethyl methacrylate) (P(DMAEMA)), and a hydrophobic polymer, poly(N-isopropylacrylamide) (P(NIPAM)), through atom transfer radical polymerization (ATRP). The synthesized RNase A-polymer conjugates (namely R-P(D-b-N)) could preserve the integrity of RNase A and exhibit a unique combination of cationic and hydrophobic properties, leading to enhanced intracellular delivery efficiency. The successful delivery of RNase A by R-P(D-b-N) conjugates effectively triggered the cell apoptosis through the mitochondria-dependent signaling pathway to achieve the anti-proliferative response. Additionally, the conjugates could inhibit cell migration and thus possess the potential for the suppression of tumor metastasis. Overall, our findings highlight that the introduction of cationic and hydrophobic moieties via ATRP provides a versatile platform for the intracellular delivery of therapeutic proteins, offering a new avenue for treating diverse diseases.
