Identification of potential circadian rhythm-related hub genes and immune infiltration in preeclampsia through bioinformatics analysis

This bioinformatics analysis provides preliminary evidence for CRH and LEP as potential circadian rhythm-related diagnostic biomarkers in PE. However, as the findings are derived from limited GEO datasets, they should be interpreted with caution, and large‑scale, multi‑center prospective studies measuring their expression in serum or placental tissues across diverse populations are required to confirm their clinical utility.
