Overexpression of pterin-4a-carbinolamine dehydratase/dimerization cofactor of hepatocyte nuclear factor 1 in human colon cancer.
Article in The American journal of pathology, 1999. 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
Pterin-4a-carbinolamine dehydratase (PCD) is a bifunctional protein also known as DCoH (dimerization co-factor of hepatocyte nuclear factor 1 (HNF1)). PCD/DCoH modulates the DNA binding specificity of HNF1, thus acting on its transcriptional activity. In addition, it participates in the recycling of tetrahydrobiopterin (BH(4)), an essential cofactor of several metabolic reactions. We investigated colorectal tumors and colorectal tumor cell lines as compared to normal colon samples in search of a potential differential expression of PCD/DCoH. Immunohistochemistry was conducted on 20 human colorectal tumors and 20 normal samples using a specific polyclonal antibody. Immunoblotting and RT-PCR analysis for PCD/DCoH and HNF1 were also performed on both human tissues and CACO-2 and HT-29 cell lines. All of the 20 tumors and both colon cancer cell lines presented a strong and widespread immunoreactivity for PCD/DCoH, contrasting with the absence of expression in the normal epithelia. We thus report the massive overexpression of PCD/DCoH in colon tumors, which is in striking contrast with the absence of staining in normal counterparts. The sharp contrast in the expression of a modulator of transcriptional activity between tumoral and normal cells may have a physiopathological role. PCD/DCoH could potentially be a new marker of malignant colon cells in vivo.
