Engineered therapeutic probiotic system and method

Abstract

The claimed invention provides therapeutic as well as protective measures against colorectal cancer by utilizing genetically modified gut bacteria (101) in conjunction with an optimized diet high in cruciferous vegetable intake. According to the claimed system and method, engineered gut bacteria maximize the therapeutic value of the cruciferous vegetable diet to eradicate, offset or prophylactically prevent the onset of colorectal cancer. In the claimed invention gut bacteria Escherichia coli bind specifically to the heparan sulphate proteoglycan on colorectal cancer cells to secrete the enzyme myrosinase to transform host-ingested glucosinolates which are natural components of cruciferous vegetables to sulphoraphane, an organic small molecule with known anti-cancer activity.
