PPAR Gamma Activators : Off-Target Against Glioma Cell Migration and Brain Invasion

Abstract EN

Today, there is increasing evidence that PPARγ agonists, including thiazolidinediones (TDZs) and nonthiazolidinediones, block the motility and invasiveness of glioma cells and other highly migratory tumor entities.

However, the mechanism(s) by which PPARγ activators mediate their antimigratory and anti-invasive properties remains elusive.

This letter gives a short review on the debate and adds to the current knowledge by applying a PPARγ inactive derivative of the TDZ troglitazone (Rezulin) which potently counteracts experimental glioma progression in a PPARγ independent manner.
