A comprehensive landscape of mechanical stress-mediated lipid metabolism in human cavernous fibroblasts.
Article in Communications biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Fibrotic diseases involve increased mechanical stress due to extracellular matrix deposition, significantly altering cellular metabolism. However, a systematic understanding of how mechanical force regulates lipid metabolism across different molecular layers remains limited. We employed an integrated multi-omics approach, including transcriptomics, Ribo-seq, proteomics, and lipidomics, to comprehensively assess the effects of mechanical stretch on lipid metabolism in human cavernous fibroblasts. Our analysis revealed that while mechanical force elicits complex multi-layered responses, post-translational regulation predominantly drives this lipid metabolic reprogramming. Lipidomics identified a significant reduction in fatty acids and an upregulation of ganglioside. Key genes central to this mechanosensitive metabolic shift were pinpointed. This study demonstrates that mechanical force hierarchically reprograms lipid metabolism. The shift from fatty acids to ganglioside underscores a key metabolic adaptation in fibroblasts. Targeting the identified critical genes may offer a promising therapeutic strategy for fibrosis-related diseases.
