Comparative omics profiling reveals differences in biomass, energy production, and vesicle transport between CHO and fast-growing CHL-YN cells.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Chinese hamster lung (CHL)-YN cells are promising novel hosts for producing therapeutic antibodies with the potential to shorten the research, development, and manufacturing timelines in biopharmaceutical production. CHL-YN cells grow twice as fast as Chinese hamster ovary (CHO) cells, with a doubling time of 8.1 h. These cells possess strong glutamine synthetase activity, allowing them to be cultured in glutamine-free media. In this study, we conducted comparative transcriptomics and proteomics among CHL-YN cells, CHO cells, and lung tissue from Chinese hamster to better understand the global characteristics of CHL-YN cells and determine whether these features are tissue-derived or unique to the cell line. Omics profiling revealed that CHL-YN cells, in contrast to CHO cells, exhibit highly activated processes and pathways related to biomass and energy production, such as translation and biosynthesis of amino acids, but less activated vesicle transport processes, such as Golgi-related vesicle transport. This study highlights distinct characteristics of CHL-YN cells, contributing to streamlined operations, shortened development timelines, and expanded options for selectable cell lines. The findings here could contribute to identifying potential biomarkers and targets for cell engineering toward improving antibody productivity and growth rate in both traditional CHO cells and next-generation host cells, CHL-YN.
