BACKGROUND Cancer causes a substantial portion of all human deaths. Many cancers, such as lung cancer, continue to be resistant to known chemotherapy regiments; thus, there is a need to identify improved treatment methods. Emerging evidence indicates that impaired cellular metabolism is the defining
