Repression of phosphoinositide-dependent protein kinase 1 expression by ciglitazone via Egr-1 represents a new approach for inhibition of lung cancer cell growth

Conclusion: Collectively, our results demonstrate that ciglitazone inhibits PDK1 expression through AMPKalpha-mediated induction of Egr-1 and Egr-1 binding to the specific DNA site in the PDK1 gene promoter, which is independent of PPARgamma. Activation of AMPKalpha by metformin enhances the effect of ciglitazone. In turn, this leads to inhibition of NSCLC cell proliferation.
