1. Accurate prediction of spontaneous preterm birth (sPTB) before 37 weeks among women presenting with preterm labour may facilitate better patient care.
2. RNA-seq facilitates systematic search of markers in the transcriptome of maternal peripheral blood, which is relatively non-invasive, compared with amniotic fluid, chorionic villi, or foetal membrane.
3. We identified 68 differentially expressed transcripts between those preterm labour women ending in sPTB and those ending in term birth. Preterm labour women tested positive for two transcripts deliver significantly sooner than those tested negative.
4. The up-regulated transcripts in sPTB were over-represented with gene-ontology terms in inflammation and defence response to bacteria and other organisms.
5. Maternal peripheral blood with sPTB-associated transcripts are potentially useful for predicting and studying sPTB.
