The recombinant chimeric antibody chHAb18 against hepatocellular carcinoma can be produced in milk of transgenic mice.

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
Biologically active recombinant monoclonal antibodies (mAbs) and their derivatives are in demand as therapeutic agents against a variety of cancers. The antibodies are generally produced by mammalian cell culture, but their production in the milk of transgenic animals would help meet the increasing demand. The mouse-human chimeric antibody chHAb18 has been proven to inhibit the invasion and metastasis of human hepatocellular carcinoma (HCC) cells by recognizing the HAb18G/CD147 molecule that is highly expressed on the surface of HCC tissue. Here, we report that transgenic mice generated by co-microinjection of two cassettes encoding the heavy and light chain genes of chHAb18 could highly express functional chHAb18 in their mammary glands. The expression level range of 1.1-7.4 mg ml(-1) was independent of transgenic copy number. Immunoassays demonstrated the ability and specificity of chHAb18 to bind purified antigen (i.e., HAb18G) or HCC cells. Recombinant chHAb18 from transgenic milk exhibited affinity almost equal to chHAb18 derived from CHO cells, and was 68% of that of the parental murine antibody, HAb18. In light of successful clinical application of HAb18, the chHAb18 expressed in mammary glands of transgenic mice constitutes an important step towards high-yield and scaled-up production of this antibody.
