WNT7B and familial pancreatic carcinoma: WNT7B, a WNT ligand, is involved in a number of cancers and contributes to drug resistance in several types of malignancies by activating canonical WNT signaling, including gemcitabine resistance in pancreatic cancer, cis-platinum resistance in cervical cancer, and doxorubicin resistance in osteosarcoma [14,15,16].
