Further, our results identified multiple individual proteins including ephrins, IGFBPs, and DLL1, previously identified as biomarkers in COVID‐19 (Baindara et al., 2022; Breikaa & Lilly, 2021; Egal et al., 2022; Mendoza et al., 2021; Mester et al., 2024). The gene discussed is DLL1; the disease is COVID-19.
