The cell-surface serine protease prostasin is lost during cervical squamous cell carcinogenesis.

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 glycosylphosphatidylinositol (GPI)-anchored serine protease prostasin has been reported to have increased expression with tumor-promoting properties in some cancer types, while expression is lost and prostasin displays tumor-suppressing properties in other cancer types. Due to these context-dependent and opposing expression patterns and functions of prostasin, characterization of each cancer type is important. In the present study, we aimed to determine the expression of prostasin in the normal cervix and in cervical squamous cell carcinoma (CSCC), the most common type of cervical cancer. We found that prostasin protein is expressed in both murine and human cervix and is consistently localized on the cell surface in suprabasal layers of squamous cells in healthy cervical epithelia. To assess whether prostasin protein is differentially expressed during cervical carcinogenesis, we performed a comprehensive immunohistochemical analysis of prostasin protein expression levels and localization in tissue arrays of paraffin-embedded human cervical carcinomas compared to the corresponding normal tissue. Prostasin protein is expressed in the well-differentiated cellular strata with expression patterns similar to pan-keratin and E-cadherin, and is lost during the dedifferentiation of epithelial cells, a hallmark of high-grade CSCC. The prostasin expression profile, with differential expression in cancer, provide valuable information that may give clues to the function(s) of this protease in normal epithelial biology and carcinogenesis.
