Increasing evidence indicates that the NOD-like receptors (NLRs) family may act as critical back-up defenses and provide synergistic responses when confronted with persistent danger. However, the precise regulatory mechanism of NLRs and the contribution of NLRs to cancer are still unknown. In our previous study, we found that estrogen receptors (ERs) have a close connection with NLRs in the inflammatory response. Here, ERs are first identified as NLRs transcription regulation factors, both regulate NLRs expression and promote inflammasome co-localization. Furthermore, we identified that NLRP3 was differentially expressed in colon normal and cancer cells, selective ER alpha antagonist could significantly decrease pro-inflammatory cytokines expression, suppress proliferation and promote apoptosis by inhibited NLRP3 expression and inflammasome activity. In short, the research demonstrates that ERs participate in the NLR-associated signaling pathway in cancer by directly regulating NLRs. Our results provide novel insight into ERs as therapeutic targets in NLR-related inflammation and cancer. (C) 2019 Elsevier Inc. All rights reserved.
