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 Cip/Kip CDK inhibitor (CKI) p21(Cip1/WAF1) has a critical role in the nucleus to limit cell proliferation by inhibiting CDK-cyclin complexes. In contrast, cytoplasmic p21 regulates cell survival and the actin cytoskeleton. These divergent functions for p21 in different cellular compartments suggest the necessity for complex regulation. In this study, we identify the CRL2(LRR-1) ubiquitin ligase as a conserved regulator of Cip/Kip CKIs that promotes the degradation of C. elegans CKI-1 and human p21. The nematode CRL2(LRR-1) complex negatively regulates nuclear CKI-1 levels to ensure G1-phase cell cycle progression in germ cells. In contrast, human CRL2(LRR1) targets cytoplasmic p21, acting as a critical regulator of cell motility that promotes a nonmotile stationary cell state by preventing p21 from inhibiting the Rho/ROCK/LIMK pathway. Inactivation of human CRL2(LRR1) leads to the activation of the actin-depolymerizing protein cofilin, dramatic reorganization of the actin cytoskeleton, and increased cell motility.
