Results showed that FZD3 protein was expressed in 17% (4/23) of HCC, 12% (3/25) of RCCC, 80% (24/30) of SCC1, 84% (21/25) of LAC, 82% (22/27) of LNSCC, 88% (21/24) of PTC, 86% (24/28) of BC, 80% (24/30) of OCCC, 85% (17/20) of CNSCC, 82% (18/22) of FTSAC, 74% (17/23) of TCC, 100% (15/15) of SCC2 and 100% (18/18) of CND (Figures 5A and 5B).
