摘要: The invention concerns the field of cell culture technology. It concerns production host cell lines with increased expression of ribosomal RNA (rRNA) achieved through introduction of nucleic acids encoding UBF or reducing expression of NoRC 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.

摘要: The present invention refers to the area of cell culture technology and relates to methods for multiplying/cloning cells, preferably cell lines, which are important to the production of biopharmaceuticals. The invention further relates to methods for manufacturing proteins and to the use of cells extracted and multiplied through single cell sorting and to media compositions that enable a multiplication of single cells. Through the use of albumin-producing, preferably HSA-producing, cells as feeder cells for the conditioning of medium or as host cells, the recloning efficiency and thereby the quantity of clones obtained can be significantly increased. A combination of these approaches is also possible. Through the use of albumin-producing, preferably HSA-producing, cells, an increase in the recloning efficiency can be achieved in serum-free and/or insulin-free medium as well, and in different cell types.

摘要: The invention concerns the field of protein production and cell culture technology. CERT is identified as a novel in vivo PKD substrate. Phosphorylation on serine 132 by PKD decreases the affinity of CERT towards its lipid target phosphatidylinositol 4-phosphate at Golgi membranes and reduces ceramide transfer activity, identifying PKD as a regulator of lipid homeostasis. The present invention shows that CERT in turn is critical for PKD activation and PKD dependent protein cargo transport to the plasma membrane. The interdependence of PKD and CERT is thus a key to the maintenance of Golgi membrane integrity and secretory transport.
摘要翻译: 本发明涉及蛋白质生产和细胞培养技术领域。 CERT被确定为体内PKD底物的新颖。 通过PKD在丝氨酸132上的磷酸化降低了CERT对高尔基体膜上的脂质靶磷脂酰肌醇4-磷酸的亲和力,降低了神经酰胺转移活性,鉴定了PKD作为脂质体内平衡的调节剂。 本发明显示CERT又对于PKD激活和PKD依赖蛋白质运送到质膜的关键。 因此,PKD和CERT的相互依存关系是维持高尔基体膜完整性和分泌转运的关键。

摘要: The invention concerns the field of cell culture technology. The invention describes production host cell lines comprising vector constructs comprising a CERT S132 A expression cassette. Those cell lines have improved growth characteristics and high CERT S132A expression levels. The invention especially concerns two cell lines deposited with the DSMZ under the number DSM ACC2989 (CHO/CERT 2.20) and DSM AC-C2990 (CHO/CERT 2.41). The invention further concerns a method of generating such preferred production host cells and a method of producing proteins using the two cell lines deposited with the DSMZ under the number DSM ACC2989 (CHO/CERT 2.20) and DSM ACC2990 (CHO/CERT 2.41).
