NR1D1-deficient mice showed increased NACHT, LRR, and PYD domain-containing protein 3 (NLRP3) inflammasome activation, and conditioned medium (CM) from NR1D1-deficient macrophages increased the proliferation and epithelial–mesenchymal transition (EMT) of lung cancer cells. This evidence concerns the gene NR1D1 and lung carcinoma.
