MEK kinase is known to regulate cell migration and proliferation.
“MEK kinase is known to regulate cell migration and proliferation34.”
From Inference of weak-form partial differential equations describing migration and proliferation mechanisms in wound healing experiments on cancer cells (2025) · cites this paper as [34]
The Introduction (page unavailable) says that ERK and Akt mediate cell proliferation and chemotaxis, and the Materials and Methods section places MEK upstream of ERK. This supports a pathway-level connection, but the paper does not specifically establish that MEK itself regulates cell migration and proliferation. (LLM, conf=0.78)

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.
