RNA transcripts that were down-regulated in the SPB placentas, relative to the STB placentas, according to the microarray experiment (Mann-Whitney test, adjusted by the Benjamini and Hochberg method, adjusted p<0.05).

aIf a probeset interrogates a RNA transcript with no gene symbol (“—”) approved by the HUGO Gene Nomenclature Committee at the European Bioinformatics Institute (http://www.genenames.org), it is shown as a “transcribed locus”. Other details on the probesets are freely accessible at http://www.netaffx.com. bOnly 15 transcripts with the greatest fold-change values are shown. The remaining 171 transcripts are shown in Table S6. SPB, spontaneous preterm birth; STB, spontaneous term birth.
