RhoA and Wnt-5a mRNA and protein expression were quantified in normal fallopian tube epithelium, benign cystadenoma (serous and mucinous), primary ovarian carcinomas, and metastatic omentum using real-time polymerase chain reaction (PCR) (Figure 1A,B) and western blotting (Figure 1I). Here, WNT5A is linked to cystadenoma.
