Carnitine palmitoyl transferase I have been identified as a tumour target for anticancer therapeutics.[60] G protein‐coupled receptors are potential targets for the treatment of colorectal cancer, and they control different cellular functions, such as tumorigenesis, etc.[61] Oxidoreductase enzymes such as NAD(P)H: quinone oxidoreductase 1 are overexpressed in different types of tumours and are a target for cancer therapy.[62] Proteases promote tumour growth and progression, which is dependent on the supply of nutrients and oxygen. Here, NQO1 is linked to cancer.
