Epigenetic regulation of BCL6 in aggresive B-cell lymphoma: role of CTCF chromatin regulator and effects of a histone deacetylase inhibitor

ABSTRACT: BCL6 is a transcriptional repressor expressed in B-lymphocytes and which expression pattern is highly regulated. Several mechanisms have been described, but BCL6 is deregulated in some types of lymphomas including Burkitt lymphoma, follicular lymphoma and diffuse large B cell lymphoma. CTC...

Sumario:ABSTRACT: BCL6 is a transcriptional repressor expressed in B-lymphocytes and which expression pattern is highly regulated. Several mechanisms have been described, but BCL6 is deregulated in some types of lymphomas including Burkitt lymphoma, follicular lymphoma and diffuse large B cell lymphoma. CTCF is a chromatin regulator. Among the multiple functions of CTCF, its role in the epigenetic regulation of genes involved in cancer such us p53, RB, MYC, etc is highlighted. Alterations in epigenetic mechanisms are frequently found in hematological diseases. Epigenetic alterations are potentially reversible using drugs. Among them is romidepsin, a histone deacetylase inhibitor already successfully used for the treatment of some types of T-cell lymphoma. This Thesis work provides new insights in the mechanisms involved in the epigenetic regulation of BCL6 and the role of CTCF and romidepsin.
