Abstract

Inhibitor of apoptosis proteins (IAPs) interact with and inhibit caspases-3, -7, and -9. This interaction can be inhibited by Smac/DIABLO, a polypeptide released from mitochondria upon initiation of the apoptotic signaling process. Here we demonstrate that the first 4-8 N-terminal amino acids of Smac/DIABLO fused to the Drosophila antennapaedia penetratin sequence, a carrier peptide, enhance the induction of apoptosis and long term antiproliferative effects of diverse antineoplastic agents including paclitaxel, etoposide, 7-ethyl-10-hydroxycamptothecin (SN-38), and doxorubicin in MCF-7 breast cancer cells. Similar effects were observed in additional breast cancer and immortalized cholangiocyte cell lines. Further analysis demonstrated that the Smac-penetratin fusion peptide crossed the cellular membrane, bound XIAP and cIAP1, displaced caspase-3 from cytoplasmic aggregates, and enhanced drug-induced caspase action in situ. These studies demonstrate that inhibition of IAP proteins can modulate the efficacy of antineoplastic agents.

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.
