Abstract

Calcium is an important second messenger involved in intra- and extracellular signaling cascades and plays an essential role in cell life and death decisions. The Ca(2+) signaling network works in many different ways to regulate cellular processes that function over a wide dynamic range due to the action of buffers, pumps and exchangers on the plasma membrane as well as in internal stores. Calcium signaling pathways interact with other cellular signaling systems such as reactive oxygen species (ROS). Although initially considered to be potentially detrimental byproducts of aerobic metabolism, it is now clear that ROS generated in sub-toxic levels by different intracellular systems act as signaling molecules involved in various cellular processes including growth and cell death. Increasing evidence suggests a mutual interplay between calcium and ROS signaling systems which seems to have important implications for fine tuning cellular signaling networks. However, dysfunction in either of the systems might affect the other system thus potentiating harmful effects which might contribute to the pathogenesis of various disorders.

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

  • Sustained elevation in cellular calcium signal stimulates higher mitochondrial ROS generation due to enhanced electron flow through respiratory chain and subsequent inhibition of complexes I and III of ubiquinone cycle.

    “However, sustained elevation in the cellular calcium signal stimulates higher mitochondrial reactive oxygen species (ROS) generation (28) due to enhanced electron flow through respiratory chain and subsequent inhibition of complexes I and III of ubiquinone (Q) cycle.”

    From Mechanistic inferences on metabolic dysfunction in posttraumatic stress disorder from an integrated model and multiomic analysis: role of glucocorticoid receptor sensitivity (2019) · cites this paper as [28]

    In “Calcium and mitochondrial ROS generation” (page unavailable), the review says calcium overload might increase mitochondrial ROS, but it also says calcium uptake can decrease ROS or leave it unchanged depending on mitochondrial conditions. It suggests increased respiratory-chain electron leakage as one possible explanation; it does not say sustained calcium elevation subsequently inhibits complexes I and III. Instead, it describes increased ROS when those complexes were inhibited by pharmacological agents. (LLM, conf=0.88)

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.
