Abstract

Wingless (Wnt) signaling regulates many aspects of development and tissue homeostasis, and aberrant Wnt signaling can lead to cancer. Upon a Wnt signal beta-catenin degradation is halted and consequently the level of beta-catenin in the cytoplasm increases. This allows entry of beta-catenin into the nucleus where it can regulate gene transcription by direct binding to members of the lymphoid enhancer factor/T cell factor (TCF) family of transcription factors. Recently, we identified Forkhead box-O (FOXO) transcription factors as novel interaction partners of beta-catenin (Essers, M. A., de Vries-Smits, L. M., Barker, N., Polderman, P. E., Burgering, B. M., and Korswagen, H. C. (2005) Science 308, 1181-1184). Here we show that the beta-catenin binding to FOXO serves a dual effect. beta-catenin, through binding, enhances FOXO transcriptional activity. In addition, FOXO competes with TCF for interaction with beta-catenin, thereby inhibiting TCF transcriptional activity. Reduced binding between TCF and beta-catenin is observed after FOXO overexpression and cellular oxidative stress, which simultaneously increases binding between beta-catenin and FOXO. Furthermore, small interfering RNA-mediated knock down of FOXO reverts loss of beta-catenin binding to TCF after cellular oxidative stress. Taken together, these results provide evidence for a cross-talk mechanism between FOXO and TCF signaling in which beta-catenin plays a central regulatory role.

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.
