Figure 3. Relations of NLRP1 expression with other parameters (TCGAportal). (A) NLRP1 expression in the new different subgroups of LUAD. The subgroup of PP had a significantly lower expression level. (B) The mutation status of several cancer-related genes with high mutation probabilities in LUAD correlated highly with the expression of NLRP1. (C) The methylation levels at multiple sites on chromosome 17 correlated highly with NLRP1 expression. TRU, terminal respiratory unit; PI, proximal inflammatory; PP, proximal proliferative; chr 17, chromosome 17.
