Tumor targeting of humanized fragment antibody secreted from transgenic rice cell suspension culture.
Article in Plant molecular biology, 2008. 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 tumor-associated glycoprotein 72 (TAG 72) has been shown to be expressed in the majority of human adenocarcinomas. In an effort to develop a technique for the safe and inexpensive production of large quantities of anti-TAG 72 humanized antibody fragments (hzAb) as a future source of clinical-grade proteins, we developed a transgenic rice cell suspension culture system. The in vivo assembly and secretion of hzAb were achieved in a transgenic rice cell culture under the control of the rice alpha amylase 3D (RAmy 3D) expression system, and the biological activities of plant-derived hzAb were determined to be quite similar to those of animal-derived antibody. Purified hzAb was shown to bind to the recombinant antigen, TAG 72, and to bind specifically to human LS 174T colon adenocarcinoma cells expressing the TAG 72 antigen, and this binding occurred to the same extent as was seen with animal-derived antibody. Plant-derived hzAb proved as effective as animal-derived antibody in targeting tumors of xenotransplanted LS 174T cells in nude mice. The results of this study indicate that the hzAb derived from plant cell suspension cultures may have great potential for pharmaceutical applications in the development of future cancer therapeutic and diagnostic protocols.
