- To determine whether BCL-B is a survival factor in malignant plasmocytes, we will analyse the level of expression of Bcl-B at the both mRNA and protein levels in a cohort of MGUS and MM patients.

简要总结
MM accounts for 10% of hematopoietic malignancies. Despite the use of various drug combinations in chemotherapy, life expectancy of MM patients does not exceed 7 years. Until now, lack of specific markers of the disease has not allowed efficient specific molecular targeting. In view of our preliminary results, the antiapoptotic protein Bcl-B could be a novel diagnostic and pronostic marker of MM. Therefore, our main objective will be to confirm that Bcl-B is indeed a novel diagnostic and pronostic marker and a new potential therapeutic target of MM. Targeting Bcl-2 family member's is a promising strategy for the treatment of hematopoietic malignancies. In this context, specific targeting of Bcl-B could improve the treatment of patients suffering MM. Of note, this could be achieved by converting the antiapoptotic function of Bcl-B to a proapoptotic one thanks to the use of small mimetic peptides derived from Nur77 one of its interactors.

结局指标
主要结局
To determine whether BCL-B is a survival factor in malignant plasmocytes, we will analyse the level of expression of Bcl-B at the both mRNA and protein levels in a cohort of MGUS and MM patients.
时间窗: 6 months
To determine whether BCL-B is a survival factor in malignant plasmocytes,we will analyse the level of expression of Bcl-B at the both mRNA and protein levels in a cohort of MGUS and MM patients. The implication of Bcl-B in malignant plasmocyte survival will be evaluated by loss of fucntion experiments (Si-RNA). This will also allow to determine whether Bcl-B is involved in the MGUS to MM transition.
次要结局
- To determine whether deregulation of BCL-B expression is associated to chimioresistances commonly observed in Multiple Myeloma, We will compare Bcl-B expression in MM patients either sensitive or resistant to conventional therapies.(6 months)
