Cells are seeded in 96 wells and are treated after 24 hours with different drugs indicated in each experiment in medium containing 1% FBS or lipoprotein deficient serum. Relative proliferation is determined using Cell Proliferation Assay Kit. Cells are incubated 1.5 hrs after adding tetrazolium salt WST-1 [2-(4-iodophenyl)-3- (4-nitrophenyl)-5-(2, 4-disulfo-phenyl)-2H-tetrazolium, monosodium salt] at 5% CO2, 37ºC and the absorbance of the treated and untreated cells are measured using a microplate reader at 420 to 480 nm. Cells seeded in 12 well plates are counted using a hemocytometer, and dead cells are assessed using trypan blue exclusion assays.
Diabetes is induced in two-month-old male rats by a single i.p. injection of freshly prepared STZ (65 mg/kg) in 0.09 M citrate buffer, pH 4.8. Control animals are injected with 0.09 mol/L citrate buffer at pH 4.8. Hyperglycemia is confirmed 48 h after streptozotocin injection by measuring tail vein blood glucose levels using a glucometer OneTouch Ultra2. Only animals with mean plasma glucose levels over 300 mg/mL are classified as diabetic. Glycemia is also assessed before treatment with Ro5-4864 or GW3965 hydrochloride and before death. Two months after STZ injection, diabetic animals are treated once a week with Ro5-4864 (3 mg/kg) or GW3965 hydrochloride (50 mg/kg). Thus, they receive four subcutaneous injections in a month. Control diabetic rats receive 200 μL of vehicle (sesame oil). Four-month-old non-diabetic male rats are injected, following the same experimental schedule, with Ro5-4864, GW3965 hydrochloride or vehicle. Rats are killed 24 h after the last treatment.

GW3965 HCl is a selective, orally active non-steroidal agonist for the liver X receptor (LXR) .
Nuclear receptors LXRα and LXRβ have an important role in control of cholesterol and fatty acid metabolism in multiple cell types. Activation of these receptors promotes bile acid synthesis in liver, inhibits intestinal cholesterol absorption and stimulates cholesterol efflux in macrophages, which will then reduce atherosclerotic risk .
In a cell-free ligand-sensing assay, GW3965 recruits the steroid receptor coactivator 1 to human LXRR with an EC50 of 125 nM. In cell-based reporter gene assays, GW3965 plays as a full agonist on hLXRα and hLXRβ with EC50 of 190 and 30 nM, respectively .
Treatment C57BL/6 mice with 10 mg/kg GW3965 HCl orally, GW3965 HCl increased the plasma concentrations of HDL cholesterol by 30% and enhanced the expression of the reverse cholesterol transporter ABCA1 in the small intestine and peripheral macrophages . In male Sprague–Dawley rats, GW3965 decreased Ang II-mediated vasopressor responses and reduced ATR gene expression, which suggested GW3965 can affect vascular reactivity .
