HEPHL1 and severe acute respiratory syndrome: Research shows that weighted gene co-expression network analysis combined with the explainable artificial intelligence algorithm LIME can comprehensively characterize the transcriptional changes in bronchial epithelial cells (including primary human bronchial epithelial cells and transformed alveolar cells) during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and identify new hub gene features such as PGLYRP4 and HEPHL1 (29).
