Transcriptomic features reveal molecular signatures associated with recombinant adeno ‐associated virus production in HEK293 cells
This study investigated the transcriptomic features of two cell lines cultured in their respective media by comparing viral-producing cultures with non-producing cultures over time in parental human embryonic kidney cells (HEK293). The results demonstrate that the innate immune response signaling pathways of host cells (e.g., RIG-I-like receptor signaling pathway, Toll-like receptor signaling pathway, cytosolic DNA sensing pathway, JAK-STAT signaling pathway) were significantly enriched and upregulated. This was accompanied by the host cellular stress responses, including endoplasmic reticulum stress, autophagy, and apoptosis in viral production. In contrast, fatty acid metabolism and neutral amino acid transport were downregulated in the late phase of viral production. Our transcriptomics analysis reveals the cell-line independent signatures for rAAV production and serves as a significant reference for further studies targeting the productivity improvement in the future.
