Research Abstract |
ASC responsible for inflammasome fomrmation is involved in both pro-inflammation and pro-apoptosis. We observed the occurrence of the colon cancer was clearly retarded by ASC deletion from Ahr-/-mouse, a prone to colon cancer. In Ahr-/-mice, it was observed that an oncogene beta-catenin was accumulated in nuclei of the intestinal epithelium associated with an increase in the epression of IL-1 1 beta and severe inflammation was suppressed. On one hand, we observed that the metastatic potential of cancer cells were enhanced by ASC knock-down, while Asc over-expression suppressed the survival of cancer cells specifically in the confluent state. When we searched for the ASC binding proteins by immunoprecipitaiton and mass spectrometer, cytoskeletal and signal transduction-relating molecules, such as Fascine and IQGAP were, and their direct interaction with ASC was confirmed. The investigation of the biological significance of the interaction is underway.
