    Abstract: A method of identifying inhibitors of the anti-apoptotic survival pathway in cancer cells is disclosed. The method comprises the steps of (a) exposing cultured wild-type cells to a candidate inhibitor at a predetermined concentration for a predetermined period of time and determining cell viability after the exposure to the candidate inhibitor; (b) exposing two or more cell lines of specifically MCL-1 or BCL-2 or BCL-X L addicted cells to the candidate inhibitor at the predetermined concentration for the predetermined period of time and determining cell viability after the exposure to the candidate inhibitor; and (c) identifying the candidate inhibitor as a MCL-1 or BCL-2 or BCL-X L inhibitor if the cell viability in step (a) is significantly higher than the cell viability in step (b). The disclosed method provides a way to identify inhibitors which selectively inhibit specific members of the BCL-2 family ( e.g ., MCL-1) by screening two or more cell lines with addictions to different and specific members of the BCL-2 family of proteins.

    Abstract: The present invention provides a pharmaceutical composition comprising naltrexone or an analogue thereof for use in the treatment of a subject having a tumour/cancer; wherein the naltrexone or the analogue thereof is to be administered to the subject in a first treatment phase, followed by a recovery phase; wherein, following the recovery phase, a small molecule signalling inhibitor selected from the group consisting of PI3-kinase inhibitors, AKT inhibitors, taxanes, antimetabolites, alkylating agents and cell cycle inhibitors is to be administered to the subject in a second treatment phase; the recovery phase being characterised by the absence of administration of the naltrexone or the analogue thereof and the small molecule signalling inhibitor. Also envisaged are a diagnostic test to assess the response of a subject to the first treatment phase, an in vitro method of testing the efficacy of a small molecule signalling inhibitor when for use in combination with naltrexone, and the use of naltrexone in such a method when in vivo.
