- Hippo signaling is a key regulator of organ size, tissue hemostasis and regeneration. Dysregulation of the Hippo pathway has been recognized in a variety of human cancers, including pancreatic cancer. YES-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) are the two major downstream effectors of the Hippo pathway. YAP and TAZ have been found to promote pancreatic tumor development and progression, even in the absence of mutant Kirsten RAS (KRAS). Pancreatic cancer is associated with an abundant stromal reaction leading to tumor growth and immune escape. It has been found that YAP and TAZ modulate behavior of pancreatic stellate cells and recruitment of tumor-associated macrophages and myeloid-derived suppressor cells. Moreover, YAP and TAZ are associated with chemoresistance and poor prognosis in pancreatic cancer. This review dissects the role of Hippo signaling in pancreatic cancer, focusing on molecular mechanisms and prospects for future intervention.

- Pigment epithelium-derived factor (PEDF) is an important antiangiogenic and antitumorigenic factor in a variety of cancer forms, including pancreatic cancer. PEDF is mainly secreted as a soluble monomeric glycoprotein. In human pancreatic cancer PEDF levels are decreased, both in the tissue and serum. The decrease is associated with increased tumor angiogenesis, fibrosis, inflammation, autophagy, occurrence of liver metastasis and worse prognosis. In murine models, loss of PEDF is sufficient to induce invasive carcinoma and this phenotype is associated with large lesions characterized by poor differentiation. Lentiviral gene transfer of PEDF has resulted in decreased microvessel density and has inhibited tumor growth. Herein we review the multifunctional role of PEDF in pancreatic cancer and its therapeutic potential.
