FOLR1 expression in healthy tissues, borderline tumours and cancers. FOLR1 mRNA expression (median values) in a) healthy controls (normal fimbriae and ovarian surface epithelium), borderline ovarian tumours (all histotypes) and ovarian cancers (all histotypes); b) in healthy fimbriae compared to healthy ovarian epithelium (p < 0.0001); c) in serous compared to mucinous borderline ovarian tumors (n.s.); d) in type I and type II ovarian cancers (p < 0.0001); Mann-Whitney test was applied (*P < 0.05, **P < 0.005, ***P < 0.0001). Units: arbitrary units normalized to TBP. Error bars: 95 % CI
