Pre-eclampsia causes complications in pregnancy and characterized by uremia, proteinuria and hypertension in unattended cases. Blood biomarkers for pre-eclampsia are lacking. In this study, microarray gene expression data from peripheral blood of pre-eclampsia women was analyzed. In our study we developed a combined network approach for hub node prediction regulated by transcription factors and microRNAs corresponding to pre-eclampsia. Differentially expressed genes (DEGs) interaction map was constructed using STRING database. JUN, RPL35, NDUFB2, ATP5I, UQCRQ, COX7C, and FN1 were predicted as potential novel hub genes. Pathway analysis showed metabolic pathways, cytokine signaling in the immune system, Wnt, and MAPK signaling pathways involvement in pre-eclampsia. Regulatory network analysis showed that transcription factors JUN and STAT1 were connected with hub nodes, and microRNAs (miRNAs) like hsa-miR-26b-5p and hsa-miR-155-5p. In conclusion, the expression pattern of hub genes, analyzed deciphers a molecular signature for understanding the pathophysiology of pre-eclampsia and prediction of biomarkers for diagnosis.
