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

As a widely used anticancer drug for the treatment of chronic myeloid leukemia, ponatinib is known to cause severe cardiovascular toxicities. Cardiomyocytes are the major functional units in the myocardium, and impairment of their viability and function plays a crucial role in cardiotoxic responses. Previous studies have indicated direct toxicity of ponatinib on cardiomyocytes, but the effect of ponatinib on adult human primary cardiomyocytes (hPCMs) remains unknown, largely due to sample scarcity and the technical challenges associated with the adult human cardiomyocyte model. Based upon our previous work establishing hPCMs as a pharmacologically competent model, we tested the direct toxicity of ponatinib on these cells. We reveal suppression of AKT, but not ERK, phosphorylation upon ponatinib treatment. Treatment of hPCMs with AKT inhibitor MK-2206 phenocopied ponatinib, while restoration of AKT signaling with UCL-TRO-1938 or insulin partially rescued hPCMs from cell death, suggesting a potential protective effect.
