The combination of the glycolysis inhibitor 2-DG and sorafenib can be effective against sorafenib-tolerant persister cancer cells

Background Chemotherapy remains a major clinical option for the successful treatment of cancer by eliminating fast-growing populations of cancer cells. However, drug resistance causes the failure of antitumor treatment. Increasing evidence suggests that a small subpopulation of cancer cells will enter a “persister state” under drug pressure. The persister cell pool constitutes a reservoir from which drug resistance may emerge. Therefore, targeting persister cells presents a therapeutic opportunity to prevent drug resistance and impede tumor relapse.
