Seven days after LMB2 injection, we extracted RNA from the whole kidney and conducted an RNA-seq analysis. Subsequently, we conducted multiple immunostaining and in situ hybridization (ISH) of differentially expressed genes (DEGs) to identify their locations and associated cell types. We also investigated the expression levels of DEGs in an additional mouse model of NS induced by adriamycin.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>After NS induction, 562 upregulated and 430 downregulated DEGs were identified using RNA-seq. An enrichment analysis revealed the upregulation of cell proliferation-related genes. We observed significant upregulation of <jats:italic>Foxm1<\/jats:italic>, a transcription factor linked to cell proliferation. Immunostaining and ISH showed that various tubular cells expressed <jats:italic>Mki67<\/jats:italic> and <jats:italic>Foxm1<\/jats:italic> during NS development. The adriamycin-induced NS model also demonstrated the upregulation of <jats:italic>Mki67<\/jats:italic> and <jats:italic>Foxm1<\/jats:italic> in tubular cells.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>NS induced the upregulation of cell proliferation-related genes in tubular cells without detectable renal dysfunction.
