Chromogenic in situ hybridization for alpha6beta4 integrin in breast cancer: correlation with protein expression.
Article in The Journal of molecular diagnostics : JMD, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 alpha6beta4 integrin is the receptor for the basement membrane protein laminin-5. Recent studies suggest that alpha6beta4 integrin expression in invasive breast carcinomas may be a poor prognostic factor. Because we have not had reliable results with commercially available antibodies for the immunohistochemical detection of alpha6beta4 integrin in archival paraffin-embedded tissues, we designed a probe to detect beta4 integrin subunit mRNA in paraffin sections. In situ hybridization for beta4 mRNA was performed on paraffin-embedded tissue sections of 25 invasive breast carcinomas using a hyperbiotinylated oligonucleotide DNA probe. Immunohistochemical staining was performed on corresponding frozen tumor sections using two commercially available antibodies to the beta4 integrin subunit. All cases positive for beta4 protein by one or both antibodies were also positive for beta4 mRNA by in situ hybridization, but three cases with beta4 mRNA expression were negative by immunohistochemistry with both antibodies. These findings suggest that in situ hybridization appears to be a sensitive method for detecting beta4 integrin mRNA, but it appears to identify some cases that either lack beta4 protein or express variants not recognized with commercial antibodies directed to particular extracellular or cytoplasmic domains.
