Abstract

Hypoxia plays a pivotal role in tumor progression. The functions of hypoxia and subsequent Bcl-2/Twist1 activation in epithelial-mesenchymal transition (EMT) and vasculogenic mimicry (VM) formation are currently unclear. This study aimed to investigate the role of Bcl-2/Twist1 cooperation in hypoxia-induced EMT and VM formation. In in vitro experiments, we found that hypoxia resulted in co-overexpression of Bcl-2 and Twist1, facilitated Twist1 nuclear translocation and promoted EMT and VM formation. Co-overexpression of Bcl-2 and Twist1 under normoxia could also induce EMT and promote VM formation. Furthermore, blocking Bcl-2 or Twist1 attenuated the effects of hypoxia on EMT progress and VM formation in hepatocellular carcinoma cells. In in vivo experiments, the mechanism by which hypoxia promoted Bcl-2 and Twist1 co-overexpression and induced EMT process and VM formation was demonstrated using murine xenograft models. These results above suggest that hypoxia could activate the cooperation of Bcl-2 and Twist1, Bcl-2 plays an important role in assisting Twist1 nuclear translocation which could change the expression of a wide range of genes and lead to the induction of EMT and VM formation.

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.
