Abstract

The mitogen activated protein (MAP) kinase cascade, leading to extracellular-regulated kinase (ERK) activation, is a key regulator of cell growth and proliferation. The effects of ERK are mediated by differences in ERK signalling dynamics, including magnitude and duration. In vivo, ERK signalling is stimulated by both growth factors and adhesion signals. A model for adhesion-mediated ERK activation is presented. Outputs of the model such as ERK and FAK activation, as well as responses to different ligand densities, are compared with published experimental data. The model then serves as a basis for understanding how adhesion may contribute to ERK signalling through changes in the dynamics of focal adhesion kinase activation. The main parameters influencing ERK are determined through screening analyses and parameter variation. With these parameters, key points in the pathway that give rise to changes in downstream signalling dynamics are identified. In particular, oncogenic Raf and Ras promote cell growth by increasing the magnitude and duration, respectively, of ERK activity.

  • The MAPK/ERK cascade is a key regulator of cell growth and proliferation, and this signaling pathway activates the binding of different integrins at the cell surface to extracellular matrix proteins.

    “The MAPK/ERK cascade is a key regulator of cell growth and proliferation, but most important, this signaling pathway activates the binding of different integrins at the cell surface to extracellular matrix proteins [60], linking its function with the up-regulated integrin pathway explained above.”

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.
