Application

STF-083010 has been used:
  • in a study to investigate the potential anti-lipotoxic effect of nicotinamide and to elucidate underlying mechanism(s)
  • as IRE1a inhibitor to study its effect on NOS 2 expression and investigate the underlying mechanisms in proinflammatory gene expression in astrocytes
  • to block endogenous XBP1 cleavage for one hour prior to palmitate exposure in order to examine whether inositol?requiring enzyme 1α (IRE1α ) activation is implicated in palmitate cytotoxicity

Biochem/physiol Actions

STF-083010 is a potent inhibitor of the ER transmembrane protein IRE1, which mediates the unfolded protein response. STF-083010 inhibits IRE1 endonuclease and mRNA splicing activity in response to endopasmic reticulum (ER) stress, but has no affect on the kinase activity of IRE1.

In obesity, adipose tissue infiltrating macrophages acquire a unique pro-inflammatory polarization, thereby playing a key role in the development of chronic inflammation and Type 2 diabetes. Increased saturated fatty acids (SFAs) levels have been proposed to drive this specific polarization.

Protein quality control mechanisms play an important role in cancer progression by providing adaptive responses and morphologic stability against genome-wide copy number alterations, aneuploidy, and conformation-altering somatic mutations. This dependency on protein quality control mechanisms creates a vulnerability that may
