Expression and purification of non-tagged recombinant mouse SPP1 in E. coli and its biological significance.
Article in Bioengineered, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Secreted phosphoprotein 1 (SPP1) is a multifunctional protein expressed by cells from a large variety of tissues. It is involved in many physiological and pathological processes, including bone metabolism, inflammation progress, tumor metastasis, injury repair, and hyperoxia-induced injury. Native SPP1 from multiple species have been isolated from the milk and urine, and recombinant SPP1 with different tags have been expressed and purified from bacteria. In our study, DNA fragments corresponding to mouse SPP1 without signal peptide were built into the pET28a(+) vector, and non-tagged recombinant mouse SPP1 (rmSPP1) was expressed in Escherichia coli BL21(DE3). rmSPP1 was purified using a novel tri-step procedure, and the product features high purity and low endotoxin level. rmSPP1 can effectively increase hepatocellular carcinoma cell (HCC) proliferation in vitro, demonstrating its biological activity.
