Abstract

Inositol 1,4,5-trisphosphate (IP3) receptors are intracellular calcium channels that are able to release calcium from intracellular stores upon activation by IP3 and modulation by calcium. IP3 receptors are involved in variety of processes during physiological, but also in the pathophysiological states. Unraveling their regulation and function, especially under the pathological situations can result in a development of new therapeutic strategies based on the IP3 receptor´s activation and/or blocking. To the stimuli that can modulate IP3 receptors belong several stress factors (e.g. immobilization stress, oxidative stress and hypoxia) and also apoptosis. Depending on the length and strength of the stress stimulus, expression of IP3 receptors can be increased, or decreased. Therefore, in this minireview modulation of IP3 receptors by some stressors is discussed. Since it was already shown that strong hypoxia might lead to the apoptosis induction, special focus will be given to the hypoxic stress and induction of apoptosis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The increased BDNF and decreased caspase 3 may be induced by calcium overload of mitochondria with high levels of cAMP-calcium signaling.

    “which may be induced by calcium overload of mitochondria with high levels of cAMP-calcium signaling”

    From Guanfacine’s mechanism of action in treating prefrontal cortical disorders: Successful translation across species (2020) · cites this paper as Lencesova & Krizanova, 2012

    The figure caption in the Conclusion (page unavailable) says that calcium transferred to mitochondria leads to activation of caspase 3, contrary to the claimed decrease. The “IP 3 receptors and apoptosis” section likewise links mitochondrial calcium accumulation to cell-death signaling. The passages found do not link this mechanism to increased BDNF or high cAMP-calcium signaling. (LLM, conf=0.84)

    Checked by a reasoning model — may be wrong.

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.
