reach
"Since inflammasomes are involved in IL-1beta secretion, we investigated whether IL-1beta suppression was mediated by inflammasomes, and found that EGCG treatment led to downregulation of the inflammasome component, NLRP1, and reduced caspase-1 activation."

reach
"For instance, Tsai et al. [46] observed that the flavonoid gallocatechin gallate (EGCG) attenuated lupus nephritis in mice by inhibiting caspase-1 activation through decreased NLRP3 mRNA expression, reducing IL-1β and IL-18 production."

reach
"In HMC-1 cell line, EGCG suppressed NF- κB activity by inhibiting caspase-1, a special caspase family protein which is responsible for the maturation of IL-1β and IL-18 and activating NF-κB signaling pathway."

reach
"We further examined the impact of EGCG on NLRP3 inflammasome activation and found that EGCG decreased both gene and protein expression of key signaling proteins in the TXNIP/NLRP3/IL‐1β axis, including TXNIP, ASC, NLRP3, caspase1, and IL‐1β (Figure 4B–D)."

reach
"EGCG dose-dependently blocked NLRP3-dependent caspase-1 activation and IL-1β maturation( Fig. 2 A, 2B)."

reach
"Furthermore, EGCG inhibited the activation of caspase-1 in HMC-1 cells."

reach
"177 In one study, EGCG resulted in NFkappaB inhibition, which was associated with reduced melanoma cell interleukin-1beta (IL-1beta) secretion, downregulation of the inflammasome component, nuclear localization leucine-rich-repeat protein 1 (NLRP1), and decreased caspase-1 activation."

reach
"In this study, we showed that EGCG prevented the activation of PI3 Kinase, MAP Kinase, caspase-1, and NF-κB signaling pathways in RANKL-simulated HMC-1 cells."

reach
"EGCG suppressed LPS-induced priming and inflammasome activation (caspase-1 cleavage) in both human and mouse macrophages."

reach
"Epigallocatechin gallate (EGCG), a tea catechin, reduced both histamine degranulation and cytokine release (TSLP, IL-1β, IL-6, IL-8) in receptor activator of NF-κB ligand (RANKL)-stimulated HMC-1 cells by targeting PI3K, MAPK, caspase-1, and NF-κB signaling cascades [57]."

reach
"In this study, we found that NO treatment resulted in caspase-1 activation and IL-1beta production, while EGCG inhibited the observed NO induced increase in IL-1beta production and caspase-1 activation, suggesting that the caspase-1 pathway is a potential therapeutic target for preventing NO induced ototoxic damage."

reach
"After stimulating HMC-1 cells with RANKL, activity of caspase-1 was significantly promoted, whereas treatment with EGCG (10 μg/ml) effectively prevented the caspase-1 activation up to 118% ( Fig. 2 A,[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"
