CD137 Signaling Mediates Pulmonary Artery Endothelial Cell Proliferation Under Hypoxia By Regulating Mitochondrial Dynamics.
Article in Journal of cardiovascular translational research, 2024. 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
Altered mitochondrial dynamics affect pulmonary artery endothelial cells (PAECs) proliferation, contributing to the development of pulmonary hypertension. CD137 signaling promotes mitochondrial fission. We hypothesize CD137 signaling is involved in the excessive proliferation of PAECs. The levels of CD137 protein were increased in the lung tissue of hypoxic mice and hypoxic-stimulated PAECs. Activation of CD137 signal in hypoxic-PAECs upregulated the levels of hypoxia-inducible factor-2α (HIF-2α), glucose transporters type 4, the lactate transporter monocarboxylate transporter 4, key glycolysis rate-limiting enzymes and promoted mitochondrial division; moreover, increased glucose uptake, lactic acid and ATP production and proliferative cells were observed in these PAECs. Whereas, knockdown HIF-2α reversed CD137 signal-mediated effects in PAECs mentioned above. Compared with wild-type mice, the proliferation of PAECs and the percentage of vascular lateral wall thickness decreased in CD137 knockout mice. Together, CD137 signal participated in pulmonary vascular remodeling through the regulation of mitochondrial dynamics dependent on HIF-2α in PAECs.
