“Background Pancreatic cancer remains stubbornly resistant to many key cytotoxic chemotherapeutic agents and novel targeted therapies. Despite intensive efforts, attempts at improving survival in the past 15 years, particularly in advanced
disease, have failed. This is true even with the introduction of molecularly targeted agents, chosen on the basis of their action on pathways that were supposedly important in pancreatic cancer development and progression . Clearly, there is a need to Selleckchem Paclitaxel understand more about the molecular mechanisms of pancreatic cancer tumorigenesis and to develop effective treatment strategies for pancreatic cancer. The mesothelin gene encodes a 69-kDa precursor protein that is proteolytically cleaved into an Nterminus secreted form and a C-terminus membrane-bound form, 40-kDa MSLN, which is a glycosylphosphatidylinositol-linked (GPI)-linked glycoprotein . The normal biological function of mesothelin is unknown. In one study, mutant mice that lacked both copies of the mesothelin gene had no detectable phenotype, and both male and female mice produced healthy offspring, suggesting that mesothelin is not involved in normal growth and development . It has recently found mesothelin is highly expressed in many common epithelial cancers.
