Abstract

Preeclampsia is a common disease in pregnant women that can only be diagnosed from 20 weeks after fertilization. Developing early diagnosis markers is urgent and would be helpful in selecting appropriate treatment strategies. The present study aimed to identify the differential expression profiles of microRNAs in the plasma between patients with preeclampsia and normal pregnancies using microarray methods. Using quantitative polymerase chain reaction (qPCR), the differentially expressed microRNAs (miRNAs or miRs) identified from the microarray analysis were validated. A total of 3 miRNAs, including hsa‑miR‑1304‑5p, hsa‑miR‑320a and hsa‑miR‑5002‑5p, were upregulated in the plasma of patients with preeclampsia pregnancies. Examination of the functions of these miRNAs demonstrated that they were involved in cell proliferation, indicating that preeclampsia affected this pathway. In addition, 26 downregulated miRNAs were identified by microarray methods. The functions of these miRNAs included immune regulation, vascular development, cancer pathology and pathology of other disease (tuberculosis, oligozoospermia, psoriasis and Alzheimer's disease). Using qPCR, the most differentially expressed miRNAs were confirmed to be hsa‑miR‑1304‑5p, hsa‑miR‑320a and hsa‑miR‑5002‑5p, which were upregulated, as well as hsa‑miR‑188‑3p, hsa‑miR‑211‑5p, hiv1‑miR‑TAR‑3p, hsa‑miR‑4432 and hsa‑miR‑4498 that were significantly downregulated in the plasma of preeclampsia patients. The present findings may be useful in the development of early diagnosis markers and treatment targets for preeclampsia.
