Few studies have evaluated Hedgehog (Hh) signaling pathway activation in
different types of ovarian tumors including benign, borderline and malignant
ovarian tumors. The present study investigated the expression of Hh signaling
pathway components (SHH, SMO, PTCH, and GLI1) in 193 ovarian epithelial tumor
specimens (including 147 malignant epithelial ovarian cancers, 30 borderline
ovarian tumors, 16 benign ovarian epithelial tumors) and 11 normal ovarian
epithelial tissues by immunohistochemistry. The results demonstrated widespread
expression of Hh pathway molecules in ovarian tumors. However, there was no
significant difference in the expression intensity of SHH among the four groups
(P>0.05). Statistically significant differences were identified in the expression
intensity of the SMO, PICH and GLI1 among groups (P<0.001). In addition,
significant differences were also revealed in the expression levels of SMO
(P=0.013) and GLI1 (P=0.0005) between the platinum drug-sensitive and
drug-resistant groups. The overexpression of SMO and GLI1 was further confirmed
in the cisplatin-resistant ovarian cancer cell line A2780/DDP by
immunofluorescence, flow cytometry and western blotting. The results revealed
that the Hh pathway components SMO, PICH and GLI1 are activated in ovarian
epithelial tumors. Novel potential associations between cisplatin resistance and
the overexpression of SMO and Gli1 in malignant epithelial ovarian cancer were
also observed, which may provide an innovative approach to the treatment of drug
resistant ovarian epithelial cancer.
