GSDMD and gastric cancer: As presented in this study, both NLRP3 and ASC expression were significantly increased in response to famotidine stimulation in BGC823 and AGS cells, leading to caspase-1 activation and IL-18 release, most important, famotidine failed to alter GSDMD expression, but induced GSDME expression, which is line with the report showed that GSDME rather than GSDMD is cleaved in chemotherapy drug-treated gastric cancer cells[15], suggesting the critical role of GSDME in famotidine-induced cell pyroptosis.
