Abstract

Abstract The association between lower circulating adiponectin (APN) levels and the development of pancreatic cancer has been reported. However, the effect of APN on the growth and survival of pancreatic cancer cells remains elusive. Here, we investigate the effects of the anti-diabetic APN receptor (AdipoR) agonist AdipoRon and APN on human pancreatic cancer cells. We found that AdipoRon, but not APN, induces MIAPaCa-2 cell death, mainly through necroptosis. Mechanistically, although both AdipoRon and APN activate AMPK and p38 MAPK in an AdipoR-dependent manner that elicits survival signals, only AdipoRon induces rapid mitochondrial dysfunction through mitochondrial Ca2+ overload, followed by superoxide production via RIPK1 and ERK1/2 activation. Oral administration of AdipoRon suppresses MIAPaCa-2 tumour growth without severe adverse effects and kills cancer cells isolated from patients with pancreatic cancer. Thus, AdipoRon could be a therapeutic agent against pancreatic cancer as well as diabetes.

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.
