"In the present study, we wished to test the hypothesis that sodium salicylate, which inhibits IKKbeta , prevents hepatic insulin resistance caused by short-term elevation of FFA."

sparser
"Insulin resistance was improved by systemic neutralization of IL-6 or salicylate inhibition of IKK-beta."

sparser
"Salicylate inhibits IKKβ, to prevent the deleterious effects of excess FFA on insulin signaling and action [ xref , xref ]."

sparser
"IKKB is inhibited by salicylates, such as aspirin and sodium salicylate (SS; xref )."

sparser
"Accordingly, abrogation of inflammatory signaling with salicylates, which inhibit IKKβ, prevents inhibitory IRS-1 phosphorylation, restoring insulin sensitivity ()."

sparser
"To support this finding, inhibition of IKKβ by salicylate was effective in ameliorating inflammation-mediated insulin resistance (Yuan et al., xref )."

sparser
"Aspirin, salicylate, and sulindac can directly bind and inhibit recombinant IKKβ, the upstream positive regulator of NF-κB ( xref )."

sparser
"Lastly, direct inhibition of IKKβ by aspirin, salicylate, and sulindac may be another mechanism that could account for the antiproliferative effects of these NSAIDs via downregulation of NF-κB-mediated proliferative genes such as interleukin-2 (IL-2), granulocyte-macrophage colony-stimulating factor (GM-CSF), c-myc, cyclin D1, and COX-2, among others."

sparser
"Salicylate inhibits IKK beta in concentrations that are achievable with dose schedules traditionally used in treating rheumatoid arthritis (3-4.5 g daily); indeed, this is likely to be the mechanism responsible for salicylate's utility in this disorder."

sparser
"The importance of NF-κB in the induction of insulin resistance is apparent in the improvements in insulin sensitivity resulting from inhibition of IKKβ by high dose salicylate [ xref ]."

sparser
"Because salicylates inhibit IKKβ [55,56] , Shoelson proposed that the hypoglycemic effects of these compounds might be due to inhibition of the NF-κB system."
