Role of Paip1 on Angiogenesis and Invasion in Pancreatic Cancer.

Summary of "Role of Paip1 on Angiogenesis and Invasion in Pancreatic Cancer."

Poly (A)-binding protein-interacting protein 1 (Paip1) was discovered as a modulator of translation initiation as a result of binding to PABP. Increasing evidence suggested that Paip1 has been implicated in several pathogenic roles. However, its clinical significance and underlying molecular mechanisms in Pancreatic cancer (PC) remain uncertain. In our present study, we found that Paip1 was over-expressed in human PC tissues. As well as poor survival, the over-expression of Paip1 was associated with lymph node (LN) metastasis of the PC samples analyzed. Paip1 silencing inhibits PC cell proliferation, metastasis, and angiogenesis, whereas over-expression of Paip1 produces the opposite effects. In all, we proposed that Paip1 contributes to PC progression and appears to be a valid prognostic factor of PC.

Medical and Biotech [MESH] Definitions

Star-shaped, myofibroblast-like cells located in the periacinar, perivascular, and periductal regions of the EXOCRINE PANCREAS. They play a key role in the pathobiology of FIBROSIS; PANCREATITIS; and PANCREATIC CANCER.

Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).

A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.

Extracts prepared from pancreatic tissue that may contain the pancreatic enzymes or other specific uncharacterized factors or proteins with specific activities. PANCREATIN is a specific extract containing digestive enzymes and used to treat pancreatic insufficiency.

Agents that induce or stimulate the PHYSIOLOGIC ANGIOGENESIS process. This is caused by a number of ANGIOGENIC PROTEINS.
