Mutated c-Ha-ras oncogene alters cytokeratin expression in the human breast epithelial cell line MCF-10A.
Article in The American journal of pathology, 1992. 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
MCF-10A, a spontaneously immortalized human breast epithelial cell line, has been transformed by transfection with the mutated c-Ha-ras oncogene obtained from T24 carcinoma cells. The pattern of cytokeratin expression was studied in MCF-10A cells in comparison with plasmid transfected or MCF-10Aneo cells, normal ras proto oncogene transfected or MCF-10AneoN cells, and transformed or MCF-10AneoT cells. Cytokeratin expression was studied by western immunoblot of total cellular proteins separated by two-dimensional gel electrophoresis. Blots with cytokeratin specific AE1 and AE3 antibodies showed identical molecular weight species of cytokeratins in MCF-10A, MCF-10Aneo, MCF-10AneoN, and MCF-10AneoT cells; however, in MCF-10AneoT cells, the intensity of immunostaining and the number of immunoreactive phosphorylated polypeptides keratins 7, 8, 15, and 16 was decreased. It was concluded that c-Ha-ras oncogene-induced transformation alters quantitatively the cytokeratin pattern of human breast epithelial cells and that these changes could explain some of the morphologic alterations observed in c-Ha-ras transformed cells.
