Aim To compare early‐onset pre‐eclampsia (EOPE) and late‐onset pre‐eclampsia (LOPE) and provide insight into the pathophysiology of pre‐eclampsia (PE). Methods Our recent work compared the transcriptomics in decidua of EOPE, LOPE and normal pregnancies (NP). Results We found there are a significant number of genes uniquely expressed in the decidua of EOPE and LOPE comparing with NP. Moreover, EOPE and LOPE have their distinct profiles. Unique EOPE‐associated genes were mainly involved in apoptosis related pathways such as ‘apoptosis’ and ‘Ras signaling pathway’. PIK3CB and BCL‐2 are the core regulatory genes in EOPE decidua, their abnormal expression caused decidual abnormal apoptosis which is relevant to the pathogenesis of EOPE. Whereas, LOPE is a more complicated entity which has more special LOPE‐associated genes involved in decidua differentiation, especially in ‘gap junction pathway’, ‘vascular smooth muscle contraction’ and ‘long‐term depression’. PIK3CB , FLT1 , CBLC and ITGA7 are the core regulatory genes differentially expressed in EOPE decidua comparing with LOPE. Conclusion In brief, the different decidual transcriptomics of EOPE and LOPE may correlate with their different etiology. These findings highlight the complex pathophysiology of PE and provide potential targets for a new treatment strategy in patients with PE.
