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

Since the discovery of ferroptosis, it has been postulated that this type of cell death could be utilized in treatments for cancer. Unfortunately, several highly aggressive tumor models are resistant to the pharmacological induction of ferroptosis. However, with the use of combined therapies, it is possible to recover sensitivity to ferroptosis in certain cellular models. Here, we discovered that co-treatment with the metabolically stable ferroptosis inducer imidazole ketone erastin (IKE) and the oxidized form of vitamin C, dehydroascorbic acid (DHAA), is a powerful therapy that induces ferroptosis in tumor cells previously resistant to IKE-induced ferroptosis. We determined that DHAA and IKE + DHAA delocalize and deplete GPX4 in tumor cells, specifically inducing lipid droplet peroxidation, which leads to ferroptosis. Moreover, in vivo, IKE + DHAA has high efficacy with regard to the eradication of highly aggressive tumors such as glioblastomas. Thus, the use of IKE + DHAA could be an effective and safe therapy for the eradication of difficult-to-treat cancers.
