WNT9A and neoplasm: In particular, transcriptome analysis of ascites-derived ovarian cancer cells and tumor-associated macrophages (TAMs) has revealed that both canonical and non-canonical Wnt ligands (i.e., WNT7A, WNT2A, WNT5A, WNT9A) are expressed in tumor cells, whereas LRP and FZD are common to both tumor cells and TAMs [43].
