A recent study published in Scientific Reports (2025) has identified a new stress biomarker in Chinese hamster ovary (CHO) cells used to produce difficult-to-express monoclonal antibodies (mAbs). The research, titled "Large-scale transcriptomics analysis reveals a novel stress biomarker in CHO cells producing difficult to express mAbs," leveraged comprehensive transcriptomic data to uncover molecular signatures associated with cellular stress during biomanufacturing.
CHO cells are widely used in the pharmaceutical industry to produce therapeutic proteins, but certain mAbs are inherently challenging to express, leading to reduced yields and increased costs. By analyzing large-scale transcriptomic datasets, the researchers pinpointed a specific biomarker that correlates with cellular stress responses under these demanding production conditions.
The identification of this biomarker offers a potential target for engineering more robust CHO cell lines, which could improve the efficiency and scalability of mAb production. The study underscores the power of transcriptomics in optimizing bioprocesses and advancing biopharmaceutical manufacturing.
