Combined proteomic and transcriptomic approaches reveal externalized keratin 8 as a potential therapeutic target involved in invasiveness of head and neck cancers.

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
Keratin 8 (K8) expressed at the surface of cancer cells, referred as externalized K8 (eK8), has been observed in a variety of carcinoma cell lines. K8 has been previously reported to be expressed in poorly differentiated head and neck squamous cell carcinoma (HNSCC); however, its role during the invasive phase of upper aerodigestive tract tumorigenesis is unknown. Cohorts of HNSCC tumors for protein and mRNA expression and panel of cell lines were used for investigation. K8 was found to be externalized in a majority of HNSCC cell lines. Among the two main K8 protein isoforms only the 54 kDa was found to be present at the plasma membrane of HNSCC cells. The plasminogen-induced invasion of HNSCC cells was inhibited by the anti-eK8 D-A10 antagonist monoclonal antibody. Overexpression of K8 mRNA and protein were both correlated with tumor aggressive features and poor outcome. The effect of eK8 neutralization on invasion, its presence exclusively in cancer cells and the association of K8 expression with aggressive features and poor clinical outcome in HNSCC unravel eK8 as key player in invasion and a promising therapeutic target in HNSCC.
