WNT7B and thymoma: Differential expression analysis of the WNT gene family in pan-cancer showed that WNT2B was expressed at low levels in most tumors, WNT5A, WNT10A and WNT7B were highly expressed in most tumors, all WNT family genes were expressed at low levels in skin cutaneous melanoma (SKCM), and all WNT family genes were highly expressed in thymoma (THYM) (Fig. 1D).
