Title Interleukin-10 gene transfer to peritoneal mesothelial cells suppresses peritoneal dissemination of gastric cancer cells due to a persistently high concentration in the peritoneal cavity.
Journal Cancer Gene Ther.
Abstract Interleukin (IL)-10 has potent biological properties including an inhibitory action on the proliferation and metastasis of various cancer cells. However, it is difficult to maintain a high concentration of this cytokine as it has a short half life. In this study, we evaluated whether peritoneal mesothelial cells (PMCs) could be suitable for maintaining a high concentration of IL-10 using adenoviral gene transfer. We also evaluated the therapeutic effects of an intraperitoneal injection with adenoviral vector containing mouse IL-10 gene (Ad-mIL-10) using a mouse peritoneal dissemination model of MKN45 gastric cancer cells. We demonstrated that in vitro transfection efficiency of a recombinant adenovirus containing the bacterial beta-galactosidase gene (Ad-LacZ) was approximately 10-fold higher for primarily isolated PMCs than MKN45. The entire peritoneum was transfected until 3 weeks after an intraperitoneal Ad-LacZ injection. Ad-mIL-10 treatment increased intraperitoneal IL-10 levels until 3 weeks after treatment, and then significantly inhibited peritoneal cancer growth by inhibiting angiogenesis. This treatment also improved cachexia and prolonged mice survival. We thus concluded that IL-10 gene transfer in PMCs could be a new strategy for the prevention of peritoneal dissemination of gastric cancer due to the resulting persistently high IL-10 concentration in the peritoneal cavity.
