SENP7 knockdown inhibited pyroptosis and NF-κB/NLRP3 inflammasome pathway activation in Raw 264.7 cells

Pyroptosis is a kind of necrotic and inflammatory programmed cell death induced by inflammatory caspases. SENP7 is a SUMO-specific protease, which mainly acts on deconjugation of SUMOs from substrate proteins. We evaluated the effect of SENP7 knockdown on pyroptosis, NF-κB signaling pathway, and NLR...

description Pyroptosis is a kind of necrotic and inflammatory programmed cell death induced by inflammatory caspases. SENP7 is a SUMO-specific protease, which mainly acts on deconjugation of SUMOs from substrate proteins. We evaluated the effect of SENP7 knockdown on pyroptosis, NF-κB signaling pathway, and NLRP3 inflammasome in Raw 264.7 cells. The results showed that the GSDMD protein mainly expressed in the cytoplasm nearby nuclei of Raw 264.7 cells. It migrated to cytomembrane with the numbers of Raw 264.7 cell decreased when LPS + ATP were administrated. Which was inhibited by SENP7 knockdown. In addition, not only the pyroptosis of Raw 264.7 cells was inhibited, the activation of NF-κB signaling pathway and NLRP3 inflammasome were also attenuated by SENP7 knockdown. The mechanism may be associated with the over SUMOylation of proteins induced by SENP7 knockdown.
