We performed the qRT-PCR analysis of TGFβ components (TGFB1, TGFB2, TGFBR1, TGFBR2), Wnt5A/ROR1/ROR2, and Hippo-related genes (YAP1, TAZ, CCN1, and CCN2) in serous ovarian cancer subtypes (LGSOC, HGSOC, BLSOC) compared to the normal ovary. This evidence concerns the gene TGFB2 and ovarian serous adenocarcinoma.
