Production of biologically active recombinant goose FSH in a single chain form with a CTP linker sequence.

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
FSH is a glycoprotein hormone secreted by the pituitary gland that is essential for gonadal development and reproductive function. In avian reproduction study, especially in avian reproduction hormone study, it is hindered by the lack of biologically active FSH. In order to overcome this shortcoming, we prepared recombinant goose FSH as a single chain molecule and tested its biological activities in the present study. Coding sequences for mature peptides of goose FSH α and β subunits were amplified from goose pituitary cDNA. A chimeric gene containing α and β subunit sequences linked by the hCG carboxyl terminal peptide coding sequence was constructed. The recombinant gene was inserted into the pcDNA3.1-Fc eukaryotic expression vector to form pcDNA-Fc-gFSHβ-CTP-α and then transfected into 293-F cells. A recombinant, single chain goose FSH was expressed and verified by SDS-PAGE and western blot analysis, and was purified using Protein A agarose affinity and gel filtration chromatography. Biological activity analysis results showed that the recombinant, chimeric goose FSH possesses the function of stimulating estradiol secretion and cell proliferation, in cultured chicken granulosa cells. These results indicated that bioactive, recombinant goose FSH has been successfully prepared in vitro. The recombinant goose FSH will have the potential of being used as a research tool for studying avian reproductive activities, and as a standard for developing avian FSH bioassays.
