Cyclin-Dependent Regulation of G 1 in Mammalian Fibroblasts

Ohtsubo, Motoaki, Roberts, James M.·1993·Science

Abstract

Eukaryotic cells become committed to proliferate during the G 1 phase of the cell cycle. In budding yeast, commitment occurs when the catalytic subunit of a protein kinase, encoded by the CDC28 gene (the homolog of the fission yeast cdc 2 + gene), binds to a positively acting regulatory subunit, a cyclin. Related kinases are also required for progression through the G 1 phase in higher eukaryotes. The role of cyclins in controlling G 1 progression in mammalian cells was tested by construction of fibroblasts that constitutively overexpress human cyclin E. This was found to shorten the duration of G 1 , decrease cell size, and diminish the serum requirement for the transition from G 1 to S phase. These observations show that cyclin levels can be rate-limiting for G 1 progression in mammalian cells and suggest that cyclin synthesis may be the target of physiological signals that control cell proliferation.

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.
