Abstract

Reactive oxygen species (ROS) are a byproduct of normal metabolism and have roles in cell signaling and homeostasis. Species include oxygen radicals and reactive nonradicals. Mechanisms exist that regulate cellular levels of ROS, as their reactive nature may otherwise cause damage to key cellular components including DNA, protein, and lipid. When the cellular antioxidant capacity is exceeded, oxidative stress can result. Pleiotropic deleterious effects of oxidative stress are observed in numerous disease states and are also implicated in a variety of drug-induced toxicities. In this paper, we examine the nature of ROS-induced damage on key cellular targets of oxidative stress. We also review evidence implicating ROS in clinically relevant, drug-related side effects including doxorubicin-induced cardiac damage, azidothymidine-induced myopathy, and cisplatin-induced ototoxicity.

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

  • The efficacy of chemotherapeutic agents that function through oxygen-dependent ROS generation-such as doxorubicin, cisplatin, and imexon-is markedly diminished in hypoxic regions due to insufficient oxygen availability.

    “For instance, the efficacy of chemotherapeutic agents that function through oxygen-dependent ROS generation—such as doxorubicin, cisplatin, and imexon—is markedly diminished in hypoxic regions due to insufficient oxygen availability [109,110,111,112].”

    From Modeling Tumor Microenvironment Complexity In Vitro: Spheroids as Physiologically Relevant Tumor Models and Strategies for Their Analysis (2025) · cites this paper as [111]

    Section 3.1.1 describes doxorubicin generating ROS by reducing molecular oxygen under aerobic conditions, and section 3.3 reports cisplatin-induced oxidative stress. These passages concern toxicity, not reduced antitumor efficacy in hypoxic regions; our copy does not establish that effect for either drug or discuss imexon (page numbers unavailable).

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.
