In our previous study, we found that CuB at 100 nM could induce pyroptosis in A549 cells through TLR4/NLRP3/GSDMD signaling pathways, and administration with CuB at 0.25 mg/kg, 0.5 mg/kg and 0.75 mg/kg inhibited the tumor growth in NSCLC xenograft mice model [28]. This evidence concerns the gene TLR4 and non-small cell lung carcinoma.
