Figure 1

Periostin is highly expressed in recurrent ovarian cancer. (A) Gene expression microarray results for sixteen paired pOC and rOC tissues. The heatmap shows data from nine genes with > twofold differences in expression. (B) POSTN expression in each matched pOC–rOC pair. POSTN is increased in the rOC specimens for 11 of the 16 pairs (p = 0.015). Microarray assay was performed once per sample. (C) IHC staining using an anti-periostin antibody shows elevated periostin protein in rOC relative to pOC, with higher levels present in the stroma. Micrographs were taken at a total magnification of × 100.
