1 · What the graph read from it

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.

2 · The registry

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-1alpha (HIF-1alpha) is destabilized via the ubiquitin-proteasome system. Thus HIF-1alpha expression is robustly upregulated by proteasome inhibition, but paradoxically its activity is reduced. In the present study, we investigated the mechanism underlying the paradoxical response of HIF-1alpha to proteasome inhibition. In both Hep3B and HEK293 cells, a proteasome inhibitor MG132 noticeably attenuated hypoxic induction of erythropoietin and VEGF mRNAs. MG132 inactivated HIF-1alpha C-terminal transactivation domain (CAD), independently of factor inhibiting HIF-1 (FIH) and inhibited p300 recruitment by HIF-1alpha. We next tested the possibility that CITED2 is involved in the HIF-1 inactivation. CITED2 was found to be degraded via the ubiquitin-proteasome system and thus was stabilized by proteasome inhibition. Both the activity and the p300 binding of HIF-1alpha were inhibited by CITED2 expression and recovered by CITED2 siRNA in the presence of MG132. These results suggest that CITED2 is stabilized by proteasome inhibition and inactivates HIF-1 by interfering with the HIF-1alpha-p300 interaction. This may be an important mode-of-action for proteasome inhibition-based cancer therapy.
