Regulatory effects of ΔFosB on proliferation and apoptosis of MCF-7 breast cancer cells.
Article in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Matrix metalloproteinase-9 (MMP-9) plays a vital role in tumor angiogenesis, cell migration, and invasiveness because it can degrade almost all basement membrane and extracellular matrix components. MMP-9 has been reported in many cancers including breast cancer, lung cancer, and colon cancer. ΔFosB in mammary epithelial cells has been shown to regulate cell proliferation, differentiation, and death. We found that ΔFosB increased the expression of MMP-9 in MCF-7 breast cancer cells. ΔFosB overexpression in MCF-7 cells increased cellular viability and decreased cell apoptosis. SB-3CT, an inhibitor of MMP-9, promoted apoptosis, inhibited cell proliferation, induced cell cycle arrest, and downregulated the expression of antiapoptotic genes Bcl-2 and Bcl-xl in MCF-7 cells. ΔFosB increased the number of MCF-7 cells in G2/M and S phases, upregulated the expression of Bcl-2 and Bcl-xl, and protected MCF-7 cells from apoptosis induced by MMP-9 inhibition. We also found that ΔFosB overexpression in MCF-7 cells inhibited Ca(2+)-induced apoptosis and promoted cell proliferation. Therefore, ΔFosB may be a potential target in breast cancer cell apoptosis by regulating the expression of MMP-9.
