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

Migration of cells and degradation of the extracellular matrix (ECM) are required for efficient tumor cell invasion, but the underlying molecular mechanisms are only partially known. The PPFIA1 gene for liprin-α1 is frequently amplified in human breast cancers. We recently demonstrated that liprin-α1 is an important regulator of cell edge dynamics during motility. We show, herein, that the liprin-α1 protein is highly expressed in human breast tumors. Functional analysis shows that liprin-α1 is specifically required for the migration and invasion of highly invasive human breast cancer MDA-MB-231 cells. We used time-lapse analysis to demonstrate defects in the motility of liprin-α1-depleted cells that include a striking instability of the lamellipodia. Liprin-α1 levels altered by either RNA interference or overexpression affected also cell spreading and the number of invadopodia per cell, but not the density of invadopodia per unit of surface area. On the other hand, silencing of liprin-α1 inhibited the degradation of the ECM, whereas its overexpression enhanced degradation, resulting in significant negative or positive effects, respectively, on the area of degradation per invadopodium. Transfection of fluorescent-labeled cortactin revealed that depletion of liprin-α1 also affected the assembly and disassembly of invadopodia, with decrease of their lifetime. Our results strongly support a novel important role of liprin-α1 in the regulation of human tumor cell invasion.
