Pancreatic cancer is the third-leading cause of cancer-related deaths in the United States. About 80 percent of the pancreatic cancer patients suffer from cachexia and, about one-third die due to complexities related to the syndrome. Cachexia leads to a loss in body weight and cachectic patients are refractory to chemotherapy. Despite recent advances, the mechanisms of pancreatic cancer- cachexia and the potential therapeutic interventions remain poorly evaluated.
Sirtuins represent a class of proteins that are regulated by metabolic fluctuations in tissues. We observed a reduced expression of Sirt1 in spontaneous PDAC mice muscles, human pancreatic cancer muscles, and myotubes treated …

The Hippo signaling pathway, originally discovered in Drosophila, consists of a core kinase cascade and has been subsequently demonstrated to control tissue growth and tumorigenesis. The core of this pathway contains MST1/2 (Mammalian sterile 20-like kinase 1/2), LATS1/2 (large tumor suppressor 1/2) and downstream effector named Yes-associated protein (YAP) and PDZ-binding motif (TAZ). MST1/2 transduce their kinase activity mainly through directly phosphorylating LATS1/2. Once phosphorylated and activated, LATS1/2 subsequently phosphorylate and inhibit YAP/TAZ from translocating to nucleus, thereby suppressing the expression of downstream pro-growth and survival genes. While recent studies provide important insight into the tumor suppressor properties of …
