1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Chemotherapy-induced cognitive impairment (CICI) is a quality of life-altering consequence of chemotherapy experienced by a large percentage of cancer survivors. Approximately half of FDA-approved anti-cancer drugs are known to produce ROS. Doxorubicin (Dox), a prototypical ROS-generating chemotherapeutic agent, generates superoxide (O2(-)•) via redox cycling. Our group previously demonstrated that Dox, which does not cross the BBB, induced oxidative damage to plasma proteins leading to TNF-α elevation in the periphery and, subsequently, in brain following cancer chemotherapy. We hypothesize that such processes play a central role in CICI. The current study tested the notion that O2(-)• is involved and likely responsible for Dox-induced plasma protein oxidation and TNF-α release. Addition of O2(-)• as the potassium salt (KO2) to plasma resulted in significantly increased oxidative damage to proteins, indexed by protein carbonyl (PC) and protein-bound HNE levels. We then adapted this protocol for use in cell culture. Incubation of J774A.1 macrophage culture using this KO2-18crown6 protocol with 1 and 10 µM KO2 resulted in dramatically increased levels of TNF-α produced. These findings, together with our prior results, provide strong evidence that O2(-)• and its resulting reactive species are critically involved in Dox-induced plasma protein oxidation and TNF-α release.
