Abstract:

The in situ polymerization strategy was applied to construct a polymeric shell on the surface of ribonuc-lease A(RNase A) to obtain n(RNase A) nanocapsules. The characterization showed that n(RNase A) exhibited a homogeneously spherical structure with hydrodynamic diameter and zeta potential values of (118.9±14.1) nm and (7.3±1.5) mV, respectively. Using fluorescence microscopic and flow cytometric analysis, n(RNase A) nanocapsules were identified to be efficiently internalized by A549 non-small cell lung cancer cells. After the internalization, n(RNase A) could further cleave RNA molecules in the cytosol, thereby inducing the cell apoptosis and inhibiting the cell proliferation. In conclusion, the present research successfully prepared a nanoformulation to facilitate the intracellular delivery of RNase A using surface-initiated in situ polymerization, and thus provided a useful idea for the construction and evaluation of other medicinal enzymes-based nanocapsules.
