Background: ASC
In regard to immune and inflammatory response, ASC/TMS1 is involved in inflammasome function (3-4). The inflammasome is a multiprotein complex that responds to cellular stress or pathogens and activates inflammatory responses. Specifically, ASC/TMS1 helps assemble the NLRP3 inflammasome complex which then activates caspase-1, followed by stimulation of proinflammatory cytokines including IL-1b and IL-18 (3-4). In terms of the role in regulating apoptosis, multiple studies have revealed that the ASC/TMS1 gene is hypermethylated in many cancers including breast, lung, glioblastomas, and melanomas (2-5). The increased methylation results in decreased gene expression, or silencing, allowing those cancer cells to escape apoptosis (2-5).
