摘要:
The invention is based on the surprising finding that treatment with a chemotherapeutic agent such as 5-fluorouracil (5-FU) and an autophagy inducer effectively inhibit the continued growth of, and prevent the recovery following drug withdrawal, of cancer cells. In vivo, drug resistance from a failure to adequately engage in apoptotic programmed cell death leads to a recurrence of cancer and tumors can remain dormant for periods of time before re-emerging as drug resistant metastases. It has been hypothesized that autophagy (Type II cell death) may help cancer cells survive in response to growth limiting conditions, such as nutrient depletion, hypoxia, absence of growth factor, or presence of cytotoxic drug. LiCl is a known autophagy inducer and accelerates cell survival to autophagic programmed cell death.
