Similarly, the overexpression of Wnt2 has also been detected in human fibroadenomas, breast cancer, pancreatic cancer, and CRC.50–53 Despite the concerns that in CRC (CRC) Wnt2 perhaps accelerated its migration and invasion,52,54 on the contrary, in other kinds of cancers such as gastric, pancreatic, and NSCLC, Wnt2 aggregates the cancer progression.55–57 With respect to its therapeutic potentials, direct silence of Wnt2 alleviated the xenograft breast cancer growth and rescued the malignance and the chemo-drugs resistance in breast cancers.58,59. This evidence concerns the gene WNT2 and Fibroadenoma.
