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 AP1 (activating protein 1), a heterodimer of the JUN and FOS proteins, promotes the invasive growth and metastasis of various tumors such as squamous cell carcinoma (SCC), breast cancer, and melanoma. AP1 activity is transcriptionally induced through a positive feedback loop. We identified the histone demethylase KDM4A (lysine-specific demethylase 4A) as a key epigenetic priming factor in this positive feedback loop. KDM4A contributed to the induction of genes encoding the AP1 transcription factors and the invasive growth and metastasis of SCC. KDM4A knockdown decreased the growth factor-induced messenger RNA expression and protein abundance of AP1 family members, including JUN and FOSL1. Mechanistically, histone demethylation by KDM4A facilitated the binding of the AP1 complex to the promoters of JUN and FOSL1, thereby promoting the positive feedback loop that maintains activation of AP1. In a mouse model of SCC, KDM4A knockdown inhibited lymph node metastasis. Moreover, the abundance of KDM4A correlated with the abundance of JUN and FOSL1 in human SCC tissues, and KDM4A expression was increased in human lymph node metastases. Our studies provide insights into the epigenetic control of AP1 and tumor invasion and suggest that KDM4A could be an important therapeutic target for inhibiting invasive SCC growth and metastasis.
