Expressing of rice ribosome inactivating protein as tool for treatment of cancer cells

January 2012

Ribosome-inactivating proteins (RIPs) are toxic proteins synthesized by many plants and some bacteria, that specifically depurinate the 28S RNA and thus interrupt protein translation. RIPs hold broad interest because of their potential use as plant defense factors against pathogens and cancer cells. The most promising way to exploit plant RIPs as weapons against cancer cells is either by designing molecules in which the...
