Abstract

The ability of activated Ras to induce growth arrest of human ovarian surface epithelial (HOSE) cells via induction of the cyclin-dependent kinase inhibitor p21(WAF1/CIP1) has been used to screen for Ras pathway signaling components using a library of RNA interference (RNAi) vectors targeting the kinome. Two known Ras-regulated kinases were identified, phosphoinositide 3-kinase p110alpha and ribosomal protein S6 kinase p70(S6K1), plus the MAP kinase kinase kinase kinase MINK, which had not previously been implicated in Ras signaling. MINK is activated after Ras induction via a mechanism involving reactive oxygen species and mediates stimulation of the stress-activated protein kinase p38 MAPK downstream of the Raf/ERK pathway. p38 MAPK activation is essential for Ras-induced p21(WAF1/CIP1) upregulation and cell cycle arrest. MINK is thus a distal target of Ras signaling in the induction of a growth-arrested, senescent-like phenotype that may act to oppose oncogenic transformation in HOSE cells.

  • Ras-induced senescence can be inhibited by using antioxidants or growing cells in low-oxygen conditions.

    “Ras-induced senescence can be inhibited by using antioxidants or growing cells in low-oxygen conditions (8, 25, 33, 51).”

    From Mitochondrial Dysfunction Contributes to Oncogene-Induced Senescence (2009) · cites this paper as [33]

    The section “Ras-Induced Reactive Oxygen Species Promote Activation of MINK and p38 MAPK” reports that antioxidant NAC inhibited Ras-induced ROS and the appearance of senescent morphology in human ovarian surface epithelial cells. It does not report that growing cells in low-oxygen conditions inhibits Ras-induced senescence; the Introduction mentions oxygen-rich culture only as part of a debate about oncogene-induced arrest. The antioxidant result concerns senescent morphology and signaling, not a demonstrated reversal of permanent growth arrest. (LLM, conf=0.85)

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.
