Gene Information

Application

Bexarotene has been used as retinoid x receptor (RXR) agonist:
  • to study its effect on human oral squamous cell carcinoma (OSCC) cell lines
  • to test for cooperative cell killing of cutaneous T cell lymphoma (CTCL) with 966
  • as a standard in HPLC for determining its potential impurities in drug substances and drug products

Bexarotene has been used:
  • to investigate its effects on the changes in renal, cardiac, hepatic, and pulmonary expression/activity of inducible nitric oxide synthase (iNOS) and CYP4F6
  • to analyze the involvement of retinoid x receptor (RXR) homo or permissive heterodimers
  • to study its potential impurities in drug substances and drug products

Biochem/physiol Actions

Bexarotene is a highly selective retinoid X receptor (RXR) agonist. It is an antineoplastic agent, already approved as an oral antineoplastic agent for cutaneous T cell lymphoma and being investigated against other cancers. A study has found that bexarotene in a mouse Alzheimer′s model lowered the most toxic form of β-amyloid peptide and increased cognitive ability. The activity in the mouse Alzheimer′s models are believed to be by activating PPARγ:RXR and LXR:RXR dimers which induces the expression of apoE and facilitates Aβ clearance and promotes microglial phagocytosis.
Bexarotene is used to treat breast cancer.
