Reduced GNG2 expression levels in mouse malignant melanomas and human melanoma cell lines.
Article in American journal of cancer research, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Heterotrimeric G protein is composed of a Gα-subunit and a Gβγ-dimer. Previous studies have revealed that Gβγ-dimers including the Gγ2 subunit (Gng2/GNG2) are associated with cell proliferation, differentiation, invasion and angiogenesis. At present, however, there is no information on the expression level of Gng2/GNG2 alone in any kind of tumor. In this study, we performed DNA microarray analysis in a benign melanocytic tumor and a malignant melanoma from RET-transgenic mice (RET-mice). Gng2 transcript expression levels in a malignant melanoma were less than 1/10 of the level in a benign tumor. The difference in Gng2 transcript expression levels between benign tumors and malignant melanomas was greatest among all of the G protein γ subunits examined in this study. Moreover, protein expression levels of Gng2 were decreased in malignant melanomas compared with those in benign melanocytic tumors in RET-mice. Analysis of human malignant melanomas also showed reduced GNG2 protein expression levels in five human malignant melanoma cell lines compared with the expression levels in normal human epithelial melanocytes (NHEM). Thus, we demonstrated for the first time that Gng2/GNG2 expression levels are reduced in malignant melanoma, suggesting that GNG2 could be a novel biomarker for malignant melanoma.
