LINC00969 binds to both EZH2 and METTL3, transcriptionally regulates the level of H3K27me3 in the NLRP3 promoter region, and posttranscriptionally modifies the m6A level in NLRP3 in an m6A-YTHDF2-dependent manner, thus epigenetically repressing NLRP3 expression to suppress the activation of the NLRP3/caspase-1/GSDMD-related classical pyroptosis signalling pathway, endowing an antipyroptotic phenotype and promoting TKI resistance in lung cancer. This evidence concerns the gene NLRP3 and lung cancer.
