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

Maf1 is a well-known RNA polymerase III repressor and functions as a tumor suppressor due to its role in inhibiting tRNA synthesis. However, the role of Maf1 in hepatocellular carcinoma (HCC) remains unclear. This study identified Aurora-A as a novel upstream regulator of Maf1 in HCC. We demonstrated that Aurora-A interacts with the C domain of Maf1 and phosphorylates it at Threonine-212, leading to increased protein stability and cytosolic accumulation of Maf1. Importantly, the Aurora-A-enhanced cytosolic localization of Maf1 promotes mitochondrial dysfunction and glycolytic activity, ultimately driving HCC cell proliferation. In contrast, mutation of the Thr-212 site abolishes these effects, confirming its critical role. Significantly, elevated Maf-1 expression correlates with unfavorable clinical outcomes in HCC, particularly among patients with high Aurora-A expression. Furthermore, HCC cells with overexpressed Maf1 have heightened sensitivity to Aurora-A inhibitors, suggesting a potential therapeutic vulnerability. Our study uncovers a non-canonical, oncogenic role of Maf1 in HCC and highlights the Aurora-A-Maf1 axis as a promising target for personalized cancer therapy.
