Especially in breast cancer, nucleotide-binding oligomerization domain (NOD)-, leucine-rich repeat (LRR)-, and pyrin domain-containing protein 1 (NLRP1); NLRP3; NLR family CARD domain containing 4 (NLRC4); and AIM2 inflammasome complex proteins show pro- or antitumoral activities with increased expression. This evidence concerns the gene NLRP1 and breast carcinoma.
