The regulatory activity of the lately cloned promoter PLUNC-p in transgenic Xenopus Laevis / 中国病理生理杂志

ABSTRACT

AIM: Our study focused on investigation of tissue specific regulatory activity of the newly cloned promoter: PLUNC-p with driving enhanced green fluorescent protein ( EGFP ). METHODS: Transgenic Xenopus Laevis system was applied.RESULTS: The green fluorescence protein directed under PLUNC-p was expressed strictly in branchial arches and epidermis of Xenopus Laevis embryos while CMV promoter showed ubiquitous regulation characteristic.CONCLUSION: PLUNC-p is able to direct epithelia specific expression of EGFP . This property of PLUNC-p might raise the possibility that lead target genes to express tissue-specifically.
