Expression of recombinant human granulocyte macrophage-colony stimulating factor (hGM-CSF) in mouse urine.

We have generated transgenic mice expressing human granulocyte macrophage-colony stimulating factor (hGM-CSF) in urine. In particular, the expression plasmid DNA containing mouse uroplakin II promoter was used to direct uroepithelium-specific transcription of transgene. In this study, hGM-CSF transcript was detected only in bladder uroepithelium as determined by northern blot analysis. Furthermore, hGM-CSF protein was detected in the suprabasal layer of the uroepithelium and ureter by immunohistochemistry. The hGM-CSF was secreted into urine at high level (up to 180 ng/ml), and enhanced proliferation of hGM-CSF-dependent human acute monocyte leukemic cells, suggesting that transgenic urine-derived hGM-CSF was bioactive. This is the first case of demonstrating biological activity of a cytokine produced in the urine of a transgenic animal. Our results demonstrate that bladder can be used as a bioreactor to produce biologically important substances. In addition, it suggests a potential application of bladder expression system to livestock for high-yield production of pharmaceuticals.[1]
