Carnitine-induced senescence in glioblastoma cells.
Article in Experimental and therapeutic medicine, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Carnitine is essential for lipid metabolism in cells and is known to possess antioxidant properties. Previous reports have suggested that antioxidants are able to induce senescence in glioblastoma cells, consequently, in the present study, we investigated the effect of carnitine on glioblastoma cells. Under conditions of hyponutrition (undernutrition), the proliferation of glioblastoma cells was attenuated and the level of intracellular carnitine was increased. Glioblastoma cell proliferation was also attenuated in cultures that were supplemented with exogenous carnitine, where the induction of senescence was detected by senescence-associated β-gal (SA-β-gal) staining. However, there was no evidence of the induction of apoptosis. These effects were not detected when cells were cultured with carnitine plus an inhibitor of p38 mitogen-activated protein kinase (MAPK). It, therefore, appears that carnitine has antioxidant actions in normal cells but induces senescence, which may be regarded as an opposite phenomenon, in glioblastoma cells. Senescence has been reported in cells exposed to temozolomide, which is a standard drug used for the treatment of glioblastoma. Carnitine could, therefore, represent an attractive alternative therapy for glioblastoma.
