Background:

GW3965 is a potent and selective activitor of liver X receptors (LXRs) with EC50 value of 190 and 30 nM respectively to hLXRαand hLXRβ.[1]
Liver X receptors belong to the nuclear receptor family. They are classified into subfamily 1 of the nuclear receptor superfamily. There are two isforms of LXRs and they are LXRαand LXRβ. LXRs play an important role in regulating glucose, fatty acid, and cholesterol homeostasis. Crystal analysis show that human LXRβ (liver X receptor β) forms heterodimer with retinoid X receptor α(RXRα) which is the partner on its cognate element. Before activation, LXRα and LXRβ can form heterodimers with the partner 9-cis RXR (retinoic acid receptor). The heterodimer will be activated by an LXR agonist or a RXR agonist. After activation, LXR will binds to LXR response element and regulated related gene expression.[2]
GW3965 can result in promotion of tumor cell death and inhibition of cell growth in GBM cells at 2μM.  GW3965 treatment at 2μM can significantly promote  increases   in  mRNA levels of ABCA1 and  IDOL, then induced cell death.[3]
GW3965 significantly reduced LDLR expression and induced ABCA1 expression in mice which was implanted U87/EGFRvIII cells at 40 mg/kg. GW3965 also blocked tumor growth at this dose.[3] GW3965 increased the expression of ABCA1and apoE at 30 mg/kg/d in APP/PS1 mice.[4]
