Synergistic anticancer effect of Grb2 and ITGA1 on cancer cells highly expressing Grb2 through suppressing ERK phosphorylation.

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
backgroundGrowth factor receptor bound protein 2 (Grb2) is known to be an adaptor protein that provides a critical link between cell surface growth factor receptors and the MAPK signaling. It was shown that high expression of Grb2 enhances cancer cells proliferation, invasion and malignant transformation.
objectiveIn this study, we aimed to systemically understand the function of Grb2 in cancer.
methodsThe expression of Grb2 in different cancer cell lines was examined from a publicly available database and we chose two cancer cell lines highly expressing Grb2 to investigate the role of Grb2. To systemically understand the function of Grb2 in cancer cells, proteomic profiles also were analyzed.
resultThe results suggested that downregulation of Grb2 reduced cell proliferation in Hela cells and Jurkat cells. In addition, knockdown of Grb2 reduced the expression of ITGA1 and inhibited the phosphorylation of ERK. Intriguingly, simultaneous inhibition of Grb2 and ITGA1 resulted in a greater inhibition of phosphorylated ERK than either inhibition of Grb2 or ITGA1, and thus triggered marked apoptosis in Hela cells and Jurkat cells. These results suggest a synergistic anticancer effect of Grb2 and ITGA1 mediated by the ERK pathway in cancer cells highly expressing Grb2. In conclusion, we provided evidence that inhibition of Grb2 and ITGA1 might be an attractive target for therapeutic intervention against the cancer growth of cancers with high Grb2 expression.
