Methods and compositions for the treatment of cancers and pathogenic infections
The subject application provides small compounds that are able to suppress autophagy in various cells. These compounds are useful in augmenting the existing treatments of various cancers and microbial/parasitic infections. Thus, the subject application also provides methods of treating various types of cancers and microbial/parasitic infections. Also provided by the subject application are methods of suppressing the expansion of autophagosomes within cells or individuals and inhibiting the lipidation of autophagy-related protein 8 (Atg8).
1. A method of increasing an individual's responsiveness to a cancer therapy comprising inhibiting Atg4 function in a cell currently undergoing the cancer therapy, said method comprising the administration of a composition comprising:
