Ribonuclease as Anticancer Therapeutics
Author(s): Kanwar SS and Kumar RKanwar SS and Kumar R
Ribonucleases (RNases) are small molecules which are highly cytotoxic in nature. They catalyse the degradation of RNA into smaller molecules rapidly in an unprotected environment. The cytotoxic properties of RNases include degradation of RNA leading to blockage of protein synthesis in malignant cells and inducing the apoptosis response. Cytotoxicity of RNases is determined by catalytic activity, stability, non-selective nature of inhibitors, positive charge on molecule and internalization. Onconase, BS-RNase and other RNases exert cytotoxic activity on cancer cells selectively by involving different cellular pathways and/ or enhance the cytotoxicity by mutation. A general mechanism of the cytotoxic activity of RNases includes the interaction of the enzyme with the cellular membrane by non-specific interactions mediated by Coulombic forces, internalization by endocytosis, translocation..
