Presentation Abstract

Pancreatic cancer is the 4th leading cause of cancer deaths in the United States, with that number increasing each year. Two compounds from marine sponges—HB-131 and HB-018—were tested for potential anti-cancer properties. Conditioned media from PANC-1 cells was used for testing. A western blot determined matrix metalloproteinase (MMP) expression, while a zymogram determined MMP activity. A sandwich enzyme-linked immunosorbent assay (ELISA) array determined the effects of these compounds in 15 different cytokines. HB-131 did not inhibit any of the cytokines tested, which suggests that its inhibition of CCL-2 is specific and not caused by inhibiting protein synthesis. In addition to inhibiting degranulation, HB-018 appeared to downregulate the inflammatory cytokine IL-23, while upregulating the anti-inflammatory cytokine IL-10. HB-131 and HB-018 lowered MMP-2 activity, which might translate to lower metastatic activity. From these findings, HB-131 and HB-018 are one step closer to making it to clinical trials.
