Rnd3 regulates lung cancer cell invasion and migration independently of ROCK1 signaling via alpha 5 integrin modulation.

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
Rnd3 regulates cellular processes commonly dysregulated in cancer, and altered Rnd3 expression has been linked to several cancer types. Here, we show lung adenocarcinoma patients expressing low levels of Rnd3 have significantly higher survival rates. To gain mechanistic insight into this correlation, we knocked down Rnd3 in lung adenocarcinoma A549 and H460 cell lines and patient-derived lung-to-brain metastasis (PDLBM) cell lines as a proxy for advanced disease. Depletion of Rnd3 expression decreases cell invasion and migration, two hallmarks of metastasis, independently of RhoA-ROCK1 signaling in both lung adenocarcinoma and PDLBM cell lines, indicating the involvement of a novel pathway. The expression of alpha 5 integrin was increased in Rnd3-depleted A549 cells, and knocking down alpha 5 integrin restored cell migration and invasion rates in A549 cells. Identification of a RhoA-ROCK1-independent mechanism by which Rnd3 modulates alpha 5 integrin expression to control cell migration and invasion provides new insights into the molecular basis of pro-malignant properties. These properties that drive the metastatic potential of lung adenocarcinoma may be exploited to target metastatic disease.
