    摘要: The invention relates to DNA-sequences, especially transcription- or expression-enhancing elements (TE elements) and their use on an expression vector in conjunction with an enhancer, a promoter, a product gene and a selectable marker. TE elements bring about an increase in the expression of the product gene, particularly when stably integrated in the eukaryotic genome, preferably the CHO-DG44 genome.

    摘要: The invention concerns the field of protein production and cell culture technology. It describes a method of producing a heterologous protein of interest in a cell comprising a. Increasing the expression or activity of a secretion enhancing gene, and b. Increasing the expression or activity of an anti-apoptotic gene, and c. Effecting the expression of said protein of interest, whereby the secretion enhancing gene is a gene encoding a protein whose expression or activity is induced during one of the following cellular processes: plasma-cell differentiation, unfolded protein response (UPR), endoplasmic reticulum overload response (EOR).

    摘要: The invention relates to DNA-sequences, especially transcription- or expression-enhancing elements (TE elements) and their use on an expression vector in conjunction with an enhancer, a promoter, a product gene and a selectable marker.The invention describes Sequence No. 1 and TE elements TE-01, -02, -03, -04, -06, -07, -08, -10, -11 or -12. Because of their small size, TE-06, TE-07 or TE-08 are particularly preferred. Sequence No. 1 originates from a sequence region located upstream from the coding region of the Ub/S27a gene from CHO cells.TE elements bring about an increase in the expression of the product gene, particularly when stably integrated in the eukaryotic genome, preferably the CHO-DG44 genome. Chromosomal positional effects are thereby overcome, shielded or cancelled out. In this way the proportion of high producers in a transfection mixture and also the absolute expression level are increased up to seven-fold.
