TSC1 and TSC2 tumor suppressors antagonize insulin signaling in cell growth
Open accessAbstract
Tuberous sclerosis is a human disease caused by mutations in the TSC1 or the TSC2 tumor suppressor gene. Previous studies of a Drosophila TSC2 homolog suggested a role for the TSC genes in maintaining DNA content, with loss of TSC2 leading to polyploidy and increased cell size. We have isolated mutations in the Drosophila homolog of the TSC1 gene. We show that TSC1 and TSC2 form a complex and function in a common pathway to control cellular growth. Unlike previous studies, our work shows that TSC1– or TSC2– cells are diploid. We find that, strikingly, the heterozygosity of TSC1 or TSC2 is sufficient to rescue the lethality of loss-of-function insulin receptor mutants. Further genetic analyses suggest that the TSC genes act in a parallel pathway that converges on the insulin pathway downstream from Akt. Taken together, our studies identified the TSC tumor suppressors as novel negative regulators of insulin signaling.

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.
