Hamsters are valuable rodent models that are distinct from mice and rats. Currently, the main hamster species used for experimental research are the Syrian golden hamster and Chinese hamster, in addition to hamster species from other countries. Chinese hamsters are small, easy to run and feed, and inexpensive. They are prominent species found only in China and are part of the experimental animal resources of Chinese specialty. Chinese hamsters are distinguished by a black stripe on their back, short tail, pair of easily retractable cheek pouches, and pair of large drooping testes in males with 22 chromosomes. Due to their unique anatomical structure and biological features, Chinese hamsters have been used as a model in biomedical research. Moreover, the breeding and use of Chinese hamsters was comprehensively studied in 1958, with significant breakthroughs. We present a thorough review of the current developments and applications of Chinese hamsters and support the use of this species as a suitable and innovative experimental research model. With the success of Chinese hamster transgenic technology, this species will become more commonly employed in biological and medical research in the future.

N-Glycosylation modulators for targeted manipulation of glycosylation for monoclonal antibodies.

Appl Microbiol Biotechnol

School of Interdisciplinary Research, Indian Institute of Technology Delhi, Hauz Khas, New Delhi, 110016, India.

Monoclonal antibodies are extensively used as biotherapeutics for treatment of a variety of diseases. Glycosylation of therapeutic antibodies is considered a critical quality attribute as it influences the effector function, circulatory half-life, immunogenicity, and eventually efficacy and patient safety. During upstream process development, media components play a significant role in determining the glycosylation profile.

Chinese hamster ovary (CHO) cells are widely used to produce recombinant proteins, including monoclonal antibodies (mAbs), through various process modes. While fed-batch (FB) processes have been the standard, a shift toward high-density perfusion processes is being driven by increased productivity, flexible facility footprints, and lower costs. Ensuring the clearance of process-related impurities, such as host cell proteins (HCPs), is crucial in biologics manufacturing.

The implementation of site-specific integration (SSI) systems in Chinese hamster ovary (CHO) cells for the production of monoclonal antibodies (mAbs) can alleviate concerns associated with production instability and reduce cell line development timelines. SSI cell line performance is driven by the interaction between genomic integration location, clonal background, and the transgene expression cassette, requiring optimization of all three parameters to maximize productivity. Systematic comparison of these parameters has been hindered by SSI platforms involving low-throughput enrichment strategies, such as cell sorting.

Chinese hamster ovary (CHO) cells play a pivotal role in the production of recombinant therapeutics. In the present study, we conducted a genome-scale pooled CRISPR knockout (KO) screening using a virus-free, recombinase-mediated cassette exchange-based platform in CHO-K1 host and CHO-K1 derived recombinant cells. Genome-wide guide RNA (gRNA) amplicon sequencing data were generated from cell libraries, as well as short- and long-term KO libraries, and validated through phenotypic assessment and gRNA read count distribution.
