To identify the key genes, functional enrichment and Protein\u2013Protein Interaction (PPI) network analysis were conducted. The expression levels of the key genes were characterized by real\u2010time quantitative polymerase chain reaction (RT\u2010qPCR) and western blot in neuron\u2010induced cell models. Additionally, possible regulatory networks of the key genes were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The screening process yielded 24 differentially expressed pivotal genes, which were predominantly enriched in processes related to epithelial cell proliferation regulation and hormone response. The PPI analysis yielded five key genes (Npas4, Nr4a3, Nr4a1, Egr4, and Egr1), which may exert regulatory roles primarily through peptide and peptide hormone responses. RT\u2010qPCR and western blot assays confirmed that the expression levels of the key genes were elevated in the neuron\u2010like differentiated cell model. However, these findings were inhibited by additional treatment with hypoxia. The analysis of the key gene regulatory network revealed that EGR1 and NR4A1 might regulate hub genes by utilizing their transcription factor properties, with EGR1 being the predominant regulator. The validation results from our cellular model indicated that upregulating EGR1 promotes neuronal\u2010like differentiation in SH\u2010SY5Y cells.<\/jats:p>\n                  <\/jats:sec>\n
