"In vitro, nebivolol treatment of palmitate incubated H9C2 cells suppressed autophagy, restored mitochondrial biogenesis, leading to decreased mitochondrial reactive oxygen species (mtROS) generation, and suppressed NLRP3 inflammasome activation."

reach
"Intriguingly, treatment with the saturated fatty acid palmitate, which has been suggested to limit NLRP3 localization to mitochondria by diminishing the content of cardiolipin [25], also reduces the interaction between ER and mitochondria [73, 74]."

reach
"miR-132 serves as a negative feedback regulator in PA induced NLRP3 inflammasome activation via FOXO3 down-regulation."

reach
"Collectively, these data suggest that miR-132 is an important modulator that plays a negative role in PA induced NLRP3 inflammasome activation, at least in part through FOXO3."

reach
"Mechanistically, PA treatment suppressed the nuclear factor-κB (NF-κB) p65 nuclear translocation and nucleotide-binding domain like receptor protein 3 (NLRP3) inflammasome activation."

reach
"RIPK2 ablation, palmitate treatment, and mevalonate kinase-deficiency also reduce autophagy and mitophagy, increase mtROS, and enhance NLRP3 activation."

reach
"Western blotting analysis of NLRP3 protein in cell lysates and supernatants revealed that the miR-132 mimic decreased the expression and release of the PA induced NLRP3 inflammasome component (XREF_FIG B)."

reach
"This second hypothesis could fit with our results showing a significant inhibitory effect mediated by oleate in PA induced NLRP3 inflammasome activation [100]."

"Gryllus bimaculatus extract has an inhibitory effect on LPS or palmitate induced NLRP3 inflammasome activation."

reach
"In conclusion, our study demonstrated that PA induces ERS in HepG2 cells and subsequently activates downstream NLRP3 inflammasome-mediated cellular injury, while PCB2 inhibits NLRP3/caspase 1/IL-1beta pathway, inflammation, and apoptosis with the presence of ERS, thereby promoting cell survival, which may provide pharmacological evidence for clinical approaches on NAFLD."

reach
"However, SalA treatment had no inhibitory effects on the PA induced activation of the NLRP3 inflammasome and the pro inflammatory cytokine secretion in TXNIP siRNA transfected HepG2 cells."

reach
"Different FFAs play distinct roles; for example, palmitate promotes IL-1β and IL-18 secretion in a dose-dependent manner , whereas omega-3 fatty acids can inhibit the NLRP3 inflammasome via GPR120 and GPR40 ."

reach
"In summary, our study identifies miR-132 as an important and novel negative feedback regulator of PA induced NLRP3 inflammasome activation in THP-1 cells."

reach
"In addition, CsA abolished the ability of Hst to decrease IL-1β production, NLRP3, and cleaved caspase-1 in PA-treated HepG2 cells (Figure 6A–C)."

reach
"In summary, the PKR inhibitor C16 acts on the PKR and eIF2alpha signal pathway to inhibit NF-kappaB activation and suppresses the NLRP3 pyroptosis signal pathway, which are both associated with mediation of inflammatory responses."

reach
"In contrast, overexpression of XIAP in hepatic cell lines resulted in the decrease of PA-induced NLRP3 activation, suggesting that XIAP mitigates lipid metabolism imbalance through the regulation of NLRP3-associated inflammatory responses in vitro."

reach
"Furthermore, oleic acid, reduces the secretion of IL-1b by bone marrow-derived macrophages upon previous stimulation with either LPS or palmitate, supporting that mono-unsaturated FAs can also prevent the over-activation of the NLRP3 inflammasome via the activation of the AMPK pathway [60] (Table 1)."

reach
"These results suggest that ASP could inhibit the activation of NLRP3 inflammasome, reduce the production of PA-induced inflammatory cytokines in HepG2 cells, and inhibit NLRP3 inflammasome."
