Soluble Expression of Bladder Cancer Biomarker Matrix Metalloproteinase 1.
Article in Journal of clinical laboratory analysis, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMatrix metalloproteinase 1 (MMP1) has been shown as a novel unique biomarker of bladder cancer in urine. MMP1 can only be detected using conventional and time-consuming methods, such as ELISA and Western. Refolded MMP1 has been achieved and used in probe screen for many years, while there is no clinical application for MMP1 detection until now. Soluble expression of MMP1 is necessary in urine detection.
methodscDNA of MMP1 has been isolated from human embryonic kidney 293(HEK293) cells. The catalytic domain of MMP1 is expressed as fusion protein with Escherichia coli thioredoxin (TrxA). The 30 kDa recombinant proteins were purified by Ni-chelating chromatography. The activity of soluble MMP1 was determined and compared with refolded MMP1 by zymography.
resultsCompared with refolded MMP1, TrxA can increase the solubility of MMP1. The soluble MMP1 has the same protein sequences with refolded MMP1 and increased 1.54-fold of gelatin-degradation activities than refolded MMP1.
conclusionSuccessfully soluble expression of MMP1 has been achieved by fusion expression and will make progress in discovering specific molecular probes against MMP1.
