Abstract:
The immune system plays important roles in pancreatic cancer. MHC class I-chain-related proteins A and B (MICA/B) and UL16-binding proteins (ULBPs) are known natural killer group 2D (NKG2D) ligands. Soluble NKG2D ligands can inhibit the activation of Natural killer (NK) cells. In pancreatic cancer, soluble ULBPs are relatively unstudied in contrast to soluble MICA/B. We examined the significance of soluble ULBPs, especially ULBP2, in pancreatic cancer. Soluble ULBP2 but neither soluble ULBP1 nor soluble ULBP3, was etected in the supernatants of pancreatic cancer cells. Soluble ULBP2 derived from pancreatic cancer cells could reduce the cytotoxicity of NK cells. Multivariate analysis demonstrated that serum soluble ULBP2 was a significant independent factor associated with poor overall survival (OS) in all pancreatic cancer patients, specifically in stage IV patients. In conclusion, pancreatic cancer-derived soluble ULBP2 might affect the prognosis in pancreatic cancer.

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
