RNA transcripts that were up-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).

aThe RNA transcript interrogated by each probeset is shown as the gene symbol and name approved by the HUGO Gene Nomenclature Committee at the European Bioinformatics Institute (http://www.genenames.org). Certain probesets interrogating the same gene may be listed as different GenBank accession numbers. This may reflect the different isoforms being interrogated. 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 225 transcripts are shown in Table S5.
cUp-regulated transcripts with higher expression levels than the PLAC4 mRNA in the placenta, according to the microarray data.
SPB, spontaneous preterm birth; STB, spontaneous term birth.
