Autophagy Is Required for Maintenance of Amino Acid Levels and Protein Synthesis under Nitrogen Starvation
Open accessAbstract
Autophagy is a transport system of cytoplasmic components to the lysosome/vacuole for degradation well conserved in eukaryotes. Autophagy is strongly induced by nutrient starvation. Several specific proteins, including amino acid synthesis enzymes and vacuolar enzymes, are increased during nitrogen starvation in wild-type cells but not in autophagy-defective delta atg7 cells despite similar mRNA levels. We further examined deficiencies in these cells. Bulk protein synthesis was substantially reduced in delta atg7 cells under nitrogen starvation compared with wild-type cells. The total intracellular amino acid pool was reduced in delta atg7 cells, and the levels of several amino acids fell below critical values. In contrast, wild-type cells maintained amino acid levels compatible with life. Autophagy-defective cells fail to maintain physiologic amino acid levels, and their inability to synthesize new proteins may explain most phenotypes associated with autophagy mutants at least partly.

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.
