Autophagy in Cancer Chemoprevention: Identification of Novel Autophagy Modulators with Anticancer Potential
Cancer cells have the ability to tolerate extreme conditions, autophagy-related stress tolerance enables cancer cells to survive by maintaining energy production that leads to cell growth and therapeutic resistance. Insufficient activation of autophagy in nutrient-deprived cancer cells may sensitize cancer cells to a broad array of chemotherapeutic agents and ionizing radiation. Therefore, identification of novel autophagy modulators with lower toxicity and better therapeutic index would be beneficial for cancer therapy. Here, we describe several currently used biochemical methods to assess autophagic activity and lysosomal function in cultured cancer cells. We also discuss both in vitro and in vivo assays to clarify the anticancer potential of novel autophagy modulators.
