Figure 7 shows a comparison of the gene expression profiles for healthy ovarian epithelial cells harvested from normal ovaries at the time of surgery using a pap brush and ovarian carcinoma epithelial cells collected by laser capture microdissection and, as was seen in comparing the cancerous versus normal stormal tissues, Gal3ST1and GalCer synthase are higher in ovarian epithelial carcinoma cells (by 5- and 2.3-fold, respectively) but ARSA, GALC and PSAP were not noticeably different (Figure 7A). This evidence concerns the gene PSAP and ovarian carcinoma.
