ARF promotes accumulation of retinoblastoma protein through inhibition of MDM2.
Article in Oncogene, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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.
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 INK4a/ARF locus, encoding two tumor suppressor proteins, p16(INK4a) and p14(ARF) (ARF), plays key roles in many cellular processes including cell proliferation, apoptosis, cellular senescence and differentiation. Inactivation of INK4a/ARF is one of the most frequent events during human cancer development. Although p16(INK4a) is a critical component in retinoblastoma protein (Rb)-mediated growth regulatory pathway, p14(ARF) plays a pivotal role in the activation of p53 upon oncogenic stress signals. A body of evidence indicates that ARF also possesses growth suppression functions independent of p53, the mechanism of which is not well understood. We have recently shown that MDM2 interacts with Rb and promotes proteasome-dependent Rb degradation. In this study, we show that ARF disrupts MDM2-Rb interaction resulting in Rb accumulation. Wild-type ARF, but not ARF mutant defective in MDM2 interaction, stabilizes Rb and inhibits colony foci formation independent of p53. In addition, ablation of Rb impairs ARF function in growth suppression. Thus, this study demonstrates that ARF plays a direct role in regulation of Rb and suggests that inactivation of ARF may lead to defects in both p53 and Rb pathways in human cancer development.
