| Research Abstract |
We have found that proliferation in pancreatic cancer cells under hypoxia is inhibited and that Hedgehog signaling is activated under hypoxia. Then we have provided the possibility that Hedgehog signaling may contribute to the mechanism of the re-entry into cell cycle from G0/G1 phase. To analyze this mechanism we have generated the hypoxia-resistant pancreatic cancer cell line and have confirmed that Hedgehog signaling, especially Smo molecule is involved in one of the mechanisms of re-entry into cell cycle from G0/G1 phase by reoxygenating this hypoxia-resistant cell line in vitro and in vivo experiments.
