Abstract: The invention concerns the field of cell culture technology. It concerns production host cell lines with increased expression of ribosomal RNA (rRNA) achieved through reducing expression of NoCR proteins, especially of TIP-5. Those cell lines have improved secretion and growth characteristics in comparison to control cell lines. The invention further concerns a method of producing proteins using the cells generated by the described method.

Abstract: The invention relates to a pharmaceutical composition comprising a compound preventing EthR from binding to the ethA promoter, for example a compound of formula 1 wherein R1 is optionally substituted phenyl or optionally substituted pyridyl; R2 (CH2)n wherein n is 1, 2, 3 or 4; R3 is CH3(CH2)m wherein m is 0, 1, 2 or 3; X1 is O, S, NH, N(CH3) or CH2; and X2 is O, S or NH; in particular 2-phenylethyl butyrate, and a thioamide or thiourea of formula 2 wherein R4 is optionally substituted phenyl, optionally substituted pyridyl, optionally substituted indolyl, —NR7R8; or —NH—N?CH—R9; and substituents R5 to R9 have the meanings indicated in the description, in particular ethionamide. The pharmaceutical composition is useful, e.g., in the treatment of multidrug-resistant tuberculosis.

Abstract: The present invention concerns the field of cell culture technology. It describes a novel method for enhancing the secretory transport of proteins in eukaryotic cells by heterologous expression of Munc18c, Sly1 or other members of the SM protein family. This method is particularly useful for the generation of optimized host cell systems with enhanced production capacity for the expression and manufacture of recombinant protein products.

Abstract: The invention relates to a novel system for gene regulation in eukaryotic cells, and methods of using the same for protein production, tissue engineering and gene therapy. In particular, the invention provides a new system for antibiotic-regulated gene expression in eukaryotic cells based on sequences from Enterobacteriaceae antibiotic resistance promoters, polypeptides that bind to the same in an antibiotic responsive manner, and nucleotides encoding such polypeptides. Further, the invention provides novel and sensitive methods of screening for candidate antibiotics.

Abstract: The present invention discloses mammalian cells useful for regulated gene expression in response to compounds being gaseous or liquid at the cultivation temperature of said mammalian cell, and non-human mammals comprising such mammalian cells. The invention further discloses methods for producing proteins in mammalian cells in a regulated way in response to inducing gaseous or liquid compounds. The invention is further directed to isolated nucleic: acids useful for constructing said mammalian cells.
