dMyc Transforms Cells into Super-Competitors

Open access
Moreno, Eduardo, Basler, Konrad·2004·Cell

Abstract

Overexpression of myc protooncogenes has been implicated in the genesis of many human tumors. Myc proteins seem to regulate diverse biological processes, but their role in tumorigenesis remains enigmatic. Here we use Drosophila imaginal discs to mimic situations in which cells with unequal levels of Myc protein are apposed and show that this invariably elicits a win/lose situation reminiscent of cell competition; cells with lower levels of dMyc are eliminated by apoptosis whereas cells with higher levels of dMyc over-proliferate. We find that this competitive behavior correlates with, and can be corrected by, the activation of the BMP/Dpp survival signaling pathway. Hence the heritable increase in dMyc levels causes cells to behave as "super-competitors" and reveals a novel mode of clonal expansion that causes, but also relies on, the killing of surrounding cells.

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.
