[Expression and its relationship of PRL-3 and RhoC in non-small cell lung cancer].
Article in Zhongguo fei ai za zhi = Chinese journal of lung cancer, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
BACKGROUND AND
objectivePhosphatase of regenerating liver-3 (PRL-3) is a newly identified protein-tyrosine phosphatase, which belongs to phosphatase of regenerating liver family, and plays a role in promoting tumor metastasis; Ras homologue C (RhoC) belongs to Rho subfamily of small-molecule G protein superfamily. However, the mechanisms of PRL-3 and RhoC are unknown. The aim of this study is to investigate the expressions of PRL-3 and RhoC proteins and their correlation to invasion and metastasis of non-small cell lung cancer (NSCLC), which may provide experiment evidence of the mechanism of PRL-3 in tumorigenesis and tumor-development.
methodsImmunohistochemical staining was used to detect the expressions of PRL-3 and RhoC in NSCLC in 92 cases, and statistical methods were used to analyse statistical significances of their expressions in different groups and their correlation.
resultsThe positive rates of PRL-3 and RhoC expressions in NSCLC were 69.6% (64/92) and 73.9% (68/92), respectively, and the expressions of PRL-3 and RhoC were closely correlated with TNM stage and lymphatic metastasis and pleural metastasis (P < 0.01), and they were correlated with each other (r = 0.754, P < 0.001).
conclusionThe expressions of PRL-3 and RhoC are higher in the higher TNM stage and lymphatic metastasis and pleural metastasis cases, and closely correlate with each other in NSCLC, which suggests that PRL-3 and RhoC might be in the same signal pathway and PRL-3 might promote the distant metastasis of cancer cell by RhoC and downstream factors.
