Phospholipase C gamma 1 regulates the Rap GEF1-Rap1 signalling axis in the control of human prostate carcinoma cell adhesion.

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
Phospholipase Cgamma1 (PLCgamma1) is activated downstream of a variety of extracellular stimuli and has previously been implicated in the regulation of motility responses central to tumour cell invasion. In this study, we used a novel RNAi vector system to achieve conditional PLCgamma1 knockdown in PC3LN3 human prostate carcinoma cells for further evaluation of PLCgamma1 in tumour cell biology. Using this approach, we revealed a role for PLCgamma1 in the regulation of PC3LN3 cell adhesion that appears to be independent of its effects on tumour cell chemotactic migration and spreading in response to extracellular matrix. Subsequent microarray analysis of PLCgamma1-knockdown cells revealed Rap GEF1 mRNA to be decreased in response to PLCgamma1 loss. This translated into a decrease in Rap GEF1 protein levels and a significant loss of Rap1 activity in PLCgamma1-knockdown cells. Transient knockdown of Rap GEF1 caused a reduction in PC3LN3 adhesion while overexpression of Rap GEF1 rescued the PLCgamma1 knockdown-induced adhesion defect. These data highlight control of the Rap GEF1-Rap1 molecular switch as a specific requirement for PLCgamma1-mediated tumour cell adhesion.
