Enhanced anti-melanoma efficacy of interferon alfa-2b via inhibition of Shp2.
Article in Cancer letters, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Interferon-α2b (IFN-α2b) is used to treat melanoma but there is a need to improve its efficacy. IFN-α2b signaling requires STAT1/STAT2 tyrosine phosphorylation and is subject to negative regulation by phosphatases. In this study, we determined whether inhibition of the protein tyrosine phosphatase Shp2 could enhance IFN-α2b responses in human melanoma cells. Shp2 knockdown increased IFN-α2b-stimulated STAT1 Tyr-701 phosphorylation and ISRE-luciferase activity even though it did not affect STAT2 Tyr-690 phosphorylation in A375 cells. In A375 tumor xenografts, Shp2 knockdown enhanced the anti-melanoma effect of IFN-α2b. Furthermore, the Shp2 inhibitor SPI-112Me increased the IFN-α2b-induced STAT1 activation and anti-proliferative response in A375 and SK-MEL-2 cells. These results demonstrate that inhibition of Shp2 can enhance the anti-melanoma activity of IFN-α2b.
