20-HETE mediates Ang II-induced cardiac hypertrophy via ROS and Ca
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
In the vascular system, angiotensin II (Ang II) mediated vasoconstriction by inducing the production of 20-hydroxyeicosatetraenoic acid (20-HETE). However, the role of 20-HETE in Ang II-induced cardiac dysfunction had yet to be fully elucidated. This study investigated the effects of Ang II on CYP4A expression and 20-HETE production in H9c2 cells using RT-qPCR, Western blot, and ELISA. The role of 20-HETE in Ang II-induced cardiac hypertrophy was examined using DHE, MitoSOX, and JC-1 staining to evaluate reactive oxygen species (ROS) generation and mitochondrial membrane potential changes. The ERK/Akt and CaN/NFAT3 signaling pathways were analyzed through Western blot. Ang II was found to promote CYP4A expression and 20-HETE production in H9c2 cells via an AT1 receptor-dependent mechanism. Additionally, the upregulation of AT1 receptor expression by 20-HETE further confirms its facilitatory effect on the Ang II signaling pathway. Inhibition of 20-HETE synthesis or blockade of its receptor, G-protein-coupled receptor 75 (GPR75), significantly reversed Ang II-induced cardiac hypertrophy. This reversal was closely associated with 20-HETE-induced ROS production, oxidative stress, and activation of the Ca
