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

The transcription factor NF-E2 p45-related factor (Nrf2) induces the expression of cytoprotective proteins that maintain and restore redox homeostasis. Nrf2 levels and activity are tightly regulated, and three subcellular populations of the transcription factor have been identified. During homeostasis, the majority of Nrf2 is degraded in the cytoplasm by ubiquitin (Ub)-mediated degradation. A second population is transcriptionally active in the nucleus, and a third population localizes to the outer mitochondrial membrane. Still unresolved are the mechanisms and factors that govern Nrf2 distribution between its subcellular locales. We show here that the Ub-conjugating enzyme UBE2E3 and its nuclear import receptor importin 11 (Imp-11) regulate Nrf2 distribution and activity. Knockdown of UBE2E3 reduces nuclear Nrf2, decreases Nrf2 target gene expression, and relocalizes the transcription factor to a perinuclear cluster of mitochondria. In a complementary manner, Imp-11 functions to restrict KEAP1, the major suppressor of Nrf2, from prematurely extracting the transcription factor off of a subset of target gene promoters. These findings identify a novel pathway of Nrf2 modulation during homeostasis and support a model in which UBE2E3 and Imp-11 promote Nrf2 transcriptional activity by restricting the transcription factor from partitioning to the mitochondria and limiting the repressive activity of nuclear KEAP1.
