Phospholipase D2 promotes degradation of hypoxia-inducible factor-1α independent of lipase activity.

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
Hypoxia-inducible factor-1α (HIF-1α) is a key transcriptional mediator that coordinates the expression of various genes involved in tumorigenesis in response to changes in oxygen tension. The stability of HIF-1α protein is determined by oxygen-dependent prolyl hydroxylation, which is required for binding of the von Hippel-Lindau protein (VHL), the recognition component of an E3 ubiquitin ligase that targets HIF-1α for ubiquitination and degradation. Here, we demonstrate that PLD2 protein itself interacts with HIF-1α, prolyl hydroxylase (PHD) and VHL to promote degradation of HIF-1α via the proteasomal pathway independent of lipase activity. PLD2 increases PHD2-mediated hydroxylation of HIF-1α by increasing the interaction of HIF-1α with PHD2. Moreover, PLD2 promotes VHL-dependent HIF-1α degradation by accelerating the association between VHL and HIF-1α. The interaction of the pleckstrin homology domain of PLD2 with HIF-1α also promoted degradation of HIF-1α and decreased expression of its target genes. These results indicate that PLD2 negatively regulates the stability of HIF-1α through the dynamic assembly of HIF-1α, PHD2 and VHL.
