Using adenoviral-mediated overexpression of a constitutively active PPARgamma mutant and the irreversible PPARgamma antagonist GW9662, we provide evidence that PPARgamma ligands induce caspase-mediated apoptosis and GADD45 expression through a receptor-dependent pathway.

Deletion analysis of the GADD45 promoter revealed that a 153-bp region between -234 and -81 bp proximal to the transcription start site, containing an Oct-1 element, was crucial for the PPARgamma ligand-mediated induction of the GADD45 promoter.

These findings suggest that activation of PPARgamma can lead to apoptosis and growth arrest in VSMCs, at least in part, by inducing Oct-1-mediated transcription of GADD45.

TRO induced GADD45 mRNA expression in a time- and dose-dependent manner.

Several mitogen-activated protein kinase (MAPK) pathways were involved in the induction of GADD45 by TRO.

Inhibition of the c-jun N-terminal kinase MAPK pathway by SP600125 partially abolished TRO-induced GADD45 mRNA, and protein expression and apoptosis.

In contrast, inhibition of the p38 MAPK pathway by SB203580, or through overexpression of a dominant-negative mutant of p38 MAPK, augmented GADD45 mRNA induction and GADD45 promoter activation as well as cell apoptosis by TRO.

In addition to gadd45alpha, the basal expression of other gadd family members including gadd45beta, gadd45gamma and gadd153 was substantially increased in Ikkbeta-/- cells.

Ikkbeta deficiency prevented the induction of gadd45beta and gadd45gamma by arsenic, whereas the induction of gadd45alpha and gadd153 was appreciably enhanced in Ikkbeta-/- cells.
