Middle-preserving pancreatectomy with reversed pancreaticogastrostomy: report of a case.

Parenchyma-sparing pancreatic resections have been reported increasingly in recent years; however, for multifocal diseases involving the head and the tail of the pancreas, total pancreatectomy is still the preferred procedure. The possible consequence of this procedure is loss of normal pancreatic parenchyma, resulting in insufficiency of pancreatic exocrine and endocrine functions. Various types of limited resection have been introduced for isolated or multiple pancreatic lesions, depending on the location of the tumor.

Hyperosmotic stress up-regulates the expression of major vault protein in SW620 human colon cancer cells.

The major vault protein (MVP) is the major constituent of the vault particle, the largest ribonuclear protein complex described to date and is identical to lung resistance-related protein (LRP). Although MVP is also expressed in several normal tissues, little is known about its physiological role. MVP played a protective role against some xenobiotics and other stresses.

Direct activation of the human major vault protein gene by DNA-damaging agents.

Vaults are barrel-shaped cytoplasmic ribonucleoprotein particles composed of three proteins. One of the components, the major vault protein (MVP) initially named the lung resistance-related protein (LRP), was found to be overexpressed in various multidrug resistant cancer cell lines and clinical samples. In this study, we investigated whether anticancer drugs could directly induce MVP protein or gene expression in the SW-620 human colorectal cancer cell line, in which MVP has been shown to be induced by the differentiation-inducing agent, sodium butyrate (NaB).
