Talin2 regulates invasion of human breast cancer MDA-MB-231 cells via alteration of the tumor microenvironment.
Article in Oncology letters, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The talin proteins are a key component of the extracellular matrix-integrin-cytoskeleton system, and our previous study suggested that talin2 contributes to the tumor invasion and metastasis processes regulated by the tumor microenvironment. In the present study, the specific effects of talin2 on the invasive ability of breast cancer cells, as well as the underlying mechanism, were investigated by creating two MDA-MB-231 cell lines with stable talin2 knockdown by specific RNA interference. Initially, it was confirmed that the expression levels of talin2 in human breast cancer tissues were upregulated compared with in normal adjacent tissues. Subsequently, invasion and wound healing assays revealed that depletion of talin2 in MDA-MB-231 cells decreased their migratory and invasive abilities. Western blot analysis demonstrated that knockdown of talin2 in MDA-MB-231 cells caused marked downregulation of the tumor microenvironment markers hypoxia-inducible factor 1α, phosphorylated ribosomal protein S6 kinase, phosphorylated protein kinase B and phosphorylated mechanistic target of rapamycin. Furthermore, knockdown of talin2 decreased the basal contents of glucose and lactic acid in the breast cancer cell line. In conclusion, the findings of the present study demonstrated that talin2 knockdown may inhibit the invasive ability of human breast cancer MDA-MB-23l cells via alterations in the tumor microenvironment.
