Melanoma is a fatal skin cancer. In this paper, we design a nanobiotechnological approach for the specific depletion of tyrosine that is essential for melanoma growth. We combine two nanobiotechnological methods into a single therapeutic agent in the form of Polylactide (PLA) nanocapsules containing a nanobiotechnological complex of polyhemoglobintyrosinase. Our results show that nanocapsules can enter into the melanoma cells to deplete tyrosine. This leads to the inhibition of tumor growth, migration and colonization in a highly malignant melanoma cell line B16F10. We also analyzed possible mechanisms of action including ROS generation, apoptosis induction and effect on cell cycle.
