Abstract:
The invention relates to the use of a skin permeating compound such as phloretin for controlling transgene expression under control of the Pseudomonas putida DOT-T1E- derived bacterial repressor TtgR, to a vector comprising the genetic code for the repressor TtgR fused to a transactivation or a transrepressor domain, to a vector comprising a TtgR- specific operator sequence (O TtgR ), a promoter and a polynucleotide coding for an endogenous or exogenous protein, and to a mammalian cell transiently or constitutively transfected with the mentioned vectors, and to mammals comprising such cells in nano- or microcontainers.
Abstract:
Recombinant expression vectors are provided comprising a 3' UTR of a light chain and an Epstein-Barr virus origin of replication. Also provided are host cells comprising such vectors and methods of producing recombinant protein with such vectors. Additional methods of producing a recombinant protein involve contacting cells with a first and second vector, each of which encode a different polypeptide chain, and wherein the second vector is present in an amount which is about 1.5 to 2.5 times as much as that of the first vector. Cells also can be transfected with a recombinant transient expression vector encoding a protein and are cultured in a medium in a membrane-enhanced culturing vessel to produce recombinant protein.

Abstract:
This invention is a gene expression product for producing target proteins or bio- products from heat-tolerant yeast by methanol induction and non-induction including its process of product usage. The product in this invention consists of Ogataea thermomethanolica yeast cells heat-tolerant species and proper plasmid vectors. For plasmid vector using methanol induction, the important part for gene expression is methanol inducible promoter from O. thermomethanolica , which is AOX promoter. While, the important part for gene expression in non-induction plasmid vector is GAP promoter which is a non-inducible promoter isolated from O. thermomethanolica . Both promoters can work under high temperature which is appropriate to apply with protein production in larger scale. Moreover, using O. thermomethanolica heat- tolerant species as host cell yeast can reduce the cost of production because it does not need an extra cooling system. In addition, there are other advantages, for example, the recombinant proteins can be produced extracellularly as the main proteins without or small amounts of host cell proteins. This makes it easier for purification step. In the case of the target protein is an enzyme, gene expression product from this invention also produce high level of enzyme activity.
