Abstract
Synthetic inducible eukaryotic promoters for the regulation of transcription of a gene achieve improved levels of protein expression and lower basal levels of gene expression. Such promoters contain at least two different classes of inducible elements, usually by modification of a native promoter containing one of the inducible elements by inserting the other of the inducible elements. In embodiments, additional metal responsive elements IR:Es) and/or glucocorticoid responsive elements (GREs) are provided to native promoters, particularly the hMT-IIA and MMTV-LTR promoters. One or more constitutive elements may be functionally disabled to provide the lower basal levels of gene expression.
