INTERVENTION IN THE ENERGY METABOLISM OF EUKARYOTE CELLS FOR THE PURPOSES OF SELECTION AND INCREASED EXPRESSION

摘要

The invention relates to a method for expressing one or more foreign genes in eukaryote cells, wherein the energy metabolism of the cells is improved by introducing nucleic acid sequences which encode sugar carrier proteins and whose expression is linked to the expression of the foreign gene. The invention also relates to suitable transformed cells and to the use thereof. More particularly the nucleic acid sequences encode glucose carrier proteins such as GLUT-1.
