title: Thyroid-specific and hormone-dependent expression of rat thyroglobulin promoter fused with bacterial chloramphenicol acetyltransferase gene in transgenic mice.
abstract: The minimal promoter of rat thyroglobulin (TG) gene (168 bp) was fused with bacterial chloramphenicol acetyltransferase (CAT) gene, and transgenic mice carrying the TGCAT gene were produced. The minimal promoter is sufficient for thyroid-specific and hormone-dependent expression of TGCAT in transgenic mice. Deletion of a region between -128 and -92 bp (TGII), which is not required for the expression of TGCAT in transient expression assays but whose sequence is most extensively conserved among different species, appears to decrease frequency of the expression of TGCAT in transgenic mice. However, the same deletion apparently has no significant effect on TG promoter activity in stably transformed rat FRTL-5 cells.
