Small molecules enhance autophagy and reduce toxicity in Huntington's disease models
Open accessAbstract
The target of rapamycin (TOR) proteins regulate various cellular processes including autophagy1, which may play a protective role in certain neurodegenerative and infectious diseases2. Here we show that a primary small-molecule screen in yeast yields novel small-molecules modulators of mammalian autophagy. We first identified novel small-molecule enhancers (SMER) and inhibitors (SMIR) of the cytostatic effects of rapamycin in Saccharomyces cerevisiae. Three SMERs induced autophagy independently of rapamycin in mammalian cells, enhancing the clearance of autophagy substrates like mutant huntingtin and A53T α-synuclein, associated with Huntington’s disease (HD) and familial Parkinson’s disease, respectively3-5. These SMERs, which appear to act either independently, or downstream, of TOR, attenuated mutant huntingtin-fragment toxicity in HD cell and Drosophila models, suggesting therapeutic potential. We also screened structural analogs of these SMERs and identified additional candidate drugs enhancing autophagy. Thus, we have demonstrated proof-of-principle for a novel approach for discovery of small-molecule modulators of mammalian autophagy.

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.
