Most biotherapeutic drugs are recombinant monoclonal antibodies which are mostly produced in monoclonal cell lines derived from Chinese hamster ovary (CHO) cells. Various clones expressing a monoclonal recombinant antibody were analyzed and a correlation of the antibody concentration and the relative mRNA level of calreticulin (CALR), glucose‐regulated protein 78 and 94 kDa (GRP78, GRP94) and spliced X‐box binding protein 1 (XPB1) was observed. By means of these results we were motivated to… Expand
Development of a fluorescent reporter system for monitoring ER stress in Chinese hamster ovary cells and its application for therapeutic protein production
TLDR
A reporter construct that detects Inositol-requiring enzyme 1 (IRE1)-alpha mediated splicing of X-box binding protein 1 (XBP1) to monitor the course of UPR activation in cell lines expressing monoclonal antibodies has utility to assist in devising engineering strategies for improved production of biotherapeutic drugs.

Evaluating the bottlenecks of recombinant IgM production in mammalian cells
Despite the fact, that monoclonal antibodies are the fastest growing group of biopharmaceuticals in development, this is not true for the IgM class, which remains as enigmatic as ever. While moreExpand
Optimized signal peptides for the development of high expressing CHO cell lines
TLDR
It was found that signal peptides derived from human albumin and human azurocidin are most appropriate to generate cell lines with clearly improved production rates suitable for commercial purposes in a product‐independent manner. Expand
Dynamics of unfolded protein response in recombinant CHO cells
TLDR
A comprehensive study encompassing major components of the protein processing pathway in the endoplasmic reticulum (ER) to elucidate its role in recombinant cells and correlates with the magnitude and timing of stress in the course of the batch culture. Expand
Temperature Down‐Shift Modifies Expression of UPR‐/ERAD‐Related Genes and Enhances Production of a Chimeric Fusion Protein in CHO Cells
TLDR
regulation of unfolded protein response (UPR) pathway genes, such as transcriptional regulatory factors and endoplasmic reticulum (ER)‐resident proteins, appear to be involved in the improvements of r‐protein production under low temperature conditions. Expand
Cellular responses to individual amino‐acid depletion in antibody‐expressing and parental CHO cell lines
TLDR
The results suggest that depletion of nonessential amino acids in cell culture plays a role in the onset of the stationary phase of production process and offer mechanistic insights into the observed growth attenuation phenotype. Expand
Expression of Recombinant Antibodies
TLDR
This review focuses on current antibody production systems including their usability for different applications, and recent developments of glycosylation-engineered yeast, insect cell lines, and transgenic plants are promising to obtain antibodies with “human-like” post-translational modifications.

Early Emergence of Adaptive Mechanisms Sustaining Ig Production: Application to Antibody Therapy
TLDR
This review uses recently published data about human B cell differentiation to show that the mechanisms necessary to adapt a metamorphosing B cell to its new secretory function appear quite early in the differentiation process i.e., at the pre-plasmablast stage, and characterizes the molecular pathways appearing at this stage.

Mammalian Cell Line Selection Strategies for High-Producers
TLDR
This chapter will provide a summary of the methodology and strategies employed to select the desired cell lines that meet the demands of the biopharmaceutical manufacturing environment from manual selection to automated systems that aid in the mammalian cell line selection process. Expand
Non‐invasive UPR monitoring system and its applications in CHO production cultures
TLDR
The results showed that the UPR activation is dynamically regulated during production culture and the observations increase the understanding of the critical role of UPR in regulating diverse phenotypes of the cells including growth, survival and recombinant protein secretion under different culture environments and processing conditions.

A study of monoclonal antibody‐producing CHO cell lines: What makes a stable high producer?
TLDR
The herein described extensive characterization studies could help understand the limitations to high‐level, stable recombinant protein production and find ways to improving and accelerating the process for high‐producer cell line generation and selection. Expand
Development of stable cell lines for production or regulated expression using matrix attachment regions.
TLDR
It is found that the use of the MAR increases the proportion of high-producing clones, thus reducing the number of clones that need to be screened, and MARs are useful in the development of stable cell lines for production or regulated expression. Expand
Use of the stress-inducible grp78/BiP promoter in targeting high level gene expression in fibrosarcoma in vivo.
TLDR
It is reported here that a truncated rat grp78 promoter with most of the distal basal elements removed can be utilized as a potent internal promoter in a retroviral vector to drive high level expression of a reporter gene in a murine fibrosarcoma model system. Expand
Efficient selection of high-producing subclones during gene amplification of recombinant Chinese hamster ovary cells by flow cytometry and cell sorting.
TLDR
A modification of a previous method that traps secreted product on the surface of the secreting cell, thus allowing direct analysis of single cell specific production rates was established and evaluated and used to select for high-producing subclones of a recombinant Chinese hamster ovary cell line producing a human antibody against HIV-1 by repeated rounds of gene amplification and cell sorting.

The presence of malfolded proteins in the endoplasmic reticulum signals the induction of glucose-regulated proteins
TLDR
Testing the hypothesis that the presence of malfolded proteins may be the primary signal for induction of GRPs by expressing wild-type and mutant forms of influenza virus haemagglutinin in simian cells shows that malfoldingper se, rather than abnormal glycosylation1, is the proximal inducer of this family of stress proteins.

TLDR
The results suggest that the mu-chain complex in the ER may be involved in the signaling pathway for the induction of ER stress proteins and may represent one regulatory mechanism operating in differentiating B-lymphocytes. Expand
