Acidosis Forces Fatty Acid Uptake and Metabolism in Cancer Cells Regardless of Genotype.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
While proteins facilitate fatty acid (FA) partitioning into plasma membranes, movement between membrane leaflets occurs through a "flip-flop" mechanism. This study provides evidence that biological acidosis, as encountered in tumors and ischemic diseases, promotes FA protonation, thereby enhancing neutral, non-ionized FA uptake. This positions the altered lipid metabolism in acid-exposed cells as a consequence, rather than a cause, of preferential FA uptake. Cancer cell vulnerability, independent of their genetic background, directly stems from this paradigm shift, as detoxifying the overload of very long-chain FA (VLCFA) becomes highly dependent on peroxisomal activity. Inhibition of peroxisomal function in acid-exposed cancer cells leads to the rerouting of these fatty acids into triglycerides within lipid droplets, but also into phospholipids, contributing to membrane alterations, triggering ER stress, and ultimately supporting cytotoxicity. Using patient-derived tumor organoids and sera from human volunteers supplemented with polyunsaturated FA (PUFA), it is shown that inhibiting peroxisomal ACOX1 selectively kills acid-exposed cancer cells, an effect exacerbated by pharmacological stimulation of glycolysis. Similar acid-driven FA uptake is observed in endothelial cells and cardiac myocytes, opening new therapeutic avenues not only cancer but also cardiovascular diseases.
