L'activation des récepteurs activés par les proliférateurs de peroxysomes beta/delta, stimule l'expression de Siah-1L et entraîne la prolifération et la migration de cellules de glioblastomes

Abstract : Glioblastoma represent the most frequent primary brain tumor in adults. We highlighted the role of PPARß/delta in glioblastoma tumorigenesis. We have shown that activation of this receptor stimulates proliferation and migration of glioblastoma cells T98G. We also showed that activation of PPARß/delta induces the expression of Siah-1L gene and that overexpression of Siah-1L stimulates cell proliferation and migration of glioblastoma cells. We also studied the regulation of Siah-1L gene and showed that its expression is induced by PPARß/delta. Cloning of Siah-1L gene promoter sequence and the study of its regulation showed that the induction of the expression of Siah-1L by PPARß/delta is mediated by a response element located at the promoter sequence
