Figure 2. Analysis of placental FR-β gene expression by qRTPCR.
RNA was extracted from whole placental tissue from sPTB (n=10), PE (n=11), IUGR (n=7), PE+IUGR (PE+I, n=7), sPTB+IAI (n=9), and TC (n=6) groups and converted to cDNA. Levels of FR-β mRNA expression were then determined by qRTPCR and normalized to levels of 18S RNA. Results are presented as medians and percentiles. The lines inside the box indicate the median, the ends of the box describe the lower and upper quartiles, and the whiskers define the smallest and largest values.
