ANALYSIS OF PML RARA ONCOGENIC COMPLEX IN ACUTE PROMYELOCYTIC LEUKEMIA

Acute promyelocytic leukemia (APL) appears to be primarily a monogenic disease characterised by a specific t(15 ;17) translocation that fuses the PML and the RARA gene to generate a PML/RAR fusion protein. PML/RARA is a transcript... see more

Project description Acute promyelocytic leukemia (APL) appears to be primarily a monogenic disease characterised by a specific t(15 ;17) translocation that fuses the PML and the RARA gene to generate a PML/RAR fusion protein. PML/RARA is a transcriptional repressor, and RARA homo-dimerisation through the coiled coil of PML was believed to be the basis for repression via enhanced binding of co-repressors. Clinically, APL is exquisitely sensitive to retinoic acid (RA), arsenic trioxide and cAMP. This cardinal feature of the disease has been used to model its pathogenesis by analyzing the response to therapy of primary cells in vivo and ex vivo. Our aim is a further understanding the pathogenesis of acute promyelocytic leukemia, in particular the molecular bases of its response to RA, arsenic and cAMP. This will be essentially achieved through the analysis of the phenotype and transcriptome of cells or animals expressing PML/RARA mutants, by applying innovative approaches in cellular and molecular biology, such as purification of tagged proteins and ChIP. We propose two main objectives: - Partners identification of the oncogenic PML/RARA complex. Subsequently, we will analyse the functional domains of the complex and the changes in the complex induced by RA, arsenic and cAMP. - Analysis of PML/RARA-dependent target gene repression. We will compare between different PML/RARA mutants in respect to the chromatin or DNA status of the target gene promoters. This project addresses new therapeutic targets in APL and other types of cancer where RARA is implicated. It is a multidisciplinary project that involves a highly valuable education for the candidate in new scientific aspects related to her research field.
