Enhanced Production of Insulin-Like Growth Factor I Fusion Protein in Escherichia coli by Coexpression of the Down-Regulated Genes Identified by Transcriptome Profiling
1 Aug 2003
Abstract excerpt
The transcriptome profiles of recombinant Escherichia coli producing human insulin-like growth factor I fusion protein (IGF-I(f)) during the high-cell-density fed-batch culture were analyzed using DNA microarrays. The expression levels of 529 genes were significantly altered after induction. About 200 genes were significantly down-regulated during the production of IGF-I(f) after induction. Among these...
