Engineering Glycosylation in CHO Cells with Natural and Artificial miRNAs

A new study published in Metabolic Engineering (2023) presents a novel system for glycosylation engineering using a combination of natural and artificial microRNAs (miRNAs). The research, available on PubMed (PMID: 36906118), aims to improve the production of therapeutic proteins in Chinese hamster ovary (CHO) cells by precisely controlling glycosylation patterns. The system leverages both endogenous miRNAs and synthetic miRNA mimics to modulate key enzymes in the glycosylation pathway. This approach offers a powerful tool for enhancing the quality and efficacy of biopharmaceuticals. For full technical details, refer to the original publication.
