The Epidermal Growth Factor Receptor Antibody Cetuximab Induces Autophagy in Cancer Cells by Downregulating HIF-1α and Bcl-2 and Activating the Beclin 1/hVps34 Complex
Open accessAbstract
Autophagy is a regulated catabolic process triggered in cells deprived of nutrients or growth factors that govern nutrient uptake. Here, we report that autophagy is induced by cetuximab, a therapeutic antibody that blocks epidermal growth factor receptor function. Cancer cell treatment with cetuximab triggered autophagosome formation, conversion of microtubule-associated protein 1 light chain 3 from its cytoplasmic to membrane-associated form, and increased acidic vesicular organelle formation. Autophagy occurred when cetuximab inhibited the class I phosphoinositide 3-kinase (PI3K)/Akt/mammalian target of rapamycin pathway, but not when it inhibited only the mitogen-activated protein/extracellular signal-regulated kinase kinase/Erk pathway, and it was accompanied by decreased levels of hypoxia inducible factor-1 α (HIF-1α) and Bcl-2. Stable overexpression of a HIF-1α mutant prevented cetuximab-induced autophagy and decrease in Bcl-2 levels. Knockdown of autophagy regulator beclin 1 or cell treatment with autophagy inhibitor 3-methyladenine, a class III PI3K (hVps34) inhibitor, also inhibited cetuximab-induced autophagy. Furthermore, knockdown of beclin 1 or Atg7 or treatment with the lysosome inhibitor chloroquine sensitized cancer cells to cetuximab-induced apoptosis. Mechanistic analysis argued that cetuximab acted by promoting an association between beclin 1 and hVps34, which was inhibited by overexpression of Bcl-2. Our findings suggest that the autophagy protects cancer cells from the proapoptotic effects of cetuximab. Cancer Res; 70(14); 5942–52. ©2010 AACR.

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.
