  • IPMK is implicated in neurodegeneration, cancer, and inflammation.

    “Over two decades, multidisciplinary research has unveiled its far-reaching biological roles and implications in diverse diseases, including neurodegeneration, cancer, and inflammation.”

    From From Obscurity to Prominence: IPMK’s Expanding Role in Cellular Signaling, Physiology, and Disease (2025) · cites this paper as [29]

    The Introduction and Results describe IPMK’s role in Toll-like receptor–induced inflammation, and the Discussion reports effects in mouse models of sepsis and endotoxemia. Although the Introduction describes IPMK as a signaling hub, our copy does not establish the claimed implications in neurodegeneration or cancer (searched for both). Page numbers were not available in the indexed passages. (LLM, conf=0.88)

  • IPMK is involved in inflammatory disorders, obesity, Alzheimer's disease, inflammatory bowel disease, and intestinal neuroendocrine tumors.

    “Over the past two decades, research utilizing animal models and human mutation analyses has revealed IPMK’s involvement in a wide array of human diseases, including inflammatory disorders [28,29], obesity [30,31], Alzheimer’s disease [32], inflammatory bowel disease [33,34], and intestinal neuroendocrine tumors [35].”
  • IPMK binds to TRAF6 and stabilizes it by impeding its proteasomal degradation, thereby activating NF-kB downstream.

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.
