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

Activating enhancer-binding protein 2gamma (AP-2gamma) is a member of the developmentally regulated AP-2 transcription factor family that regulates the expression of many downstream genes. Whereas the effects of AP-2alpha overexpression on cell growth are fairly well established, the cellular effects of AP-2gamma overexpression are less well studied. Our new findings show that AP-2gamma significantly upregulates p21 mRNA and proteins, inhibits cell growth, and decreases clonogenic survival. Cell cycle analysis revealed that forced AP-2gamma expression induced G1-phase arrest, decreased DNA synthesis, and decreased the fraction of cells in S phase. AP-2gamma expression also led to cyclin D1 repression, decreased Rb phosphorylation, and decreased E2F activity in breast carcinoma cells. AP-2gamma binding to the p21 promoter was observed in vivo, and the absence of growth inhibition in response to AP-2gamma expression in p21(-/-) cells demonstrated that p21 caused, at least in part, AP-2-induced cell cycle arrest. Finally, the tumor growth of human breast carcinoma cells in vivo was inhibited by the expression of AP-2gamma relative to empty vector-infected cells, suggesting that AP-2gamma acts as a tumor suppressor. In summary, expression of either AP-2gamma or AP-2alpha inhibited breast carcinoma cell growth; thus, these genes may be therapeutic targets for breast cancer.
