Simultaneously, a CCK-8 assay and Crystal Violet staining uncovered that after M. bovis infection, RBMX2 knockout EBL cells had significantly higher CCK-8 cell proliferation levels than wild-type EBL cells at both 72 and 96 hours post-infection (hpi) (Figures 1G, H). The gene discussed is RBMX2; the disease is infection.
