Abstract

Autophagy has emerged as a field of rapidly growing interest with implications in several disease conditions, such as cancer, infectious diseases, and neurodegenerative diseases. Autophagy is a major degradation pathway for aggregate-prone, intracytosolic proteins causing neurodegenerative disorders, such as Huntington's disease and forms of Parkinson's disease. Up-regulating autophagy may be a tractable therapeutic intervention for clearing these disease-causing proteins. The identification of autophagy-enhancing compounds would be beneficial not only in neurodegenerative diseases but also in other conditions where up-regulating autophagy may act as a protective pathway. Furthermore, small molecule modulators of autophagy may also be useful in dissecting pathways governing mammalian autophagy. In this chapter, we highlight assays that can be used for the identification of autophagy regulators, such as measuring the clearance of mutant aggregate-prone proteins or of autophagic flux with bafilomycin A(1). Using these methods, we recently described several mTOR-independent autophagy-enhancing compounds that have protective effects in various models of Huntington's disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
