Description générale

Expression of BOB.1/OBF.1 is restricted largely to mature B-cells. Germinal center B-cells normally demonstrate strong staining for BOB.1, as do mantle-zone B-cells, and plasma cells. Analyses of BOB.1/OBF.1 expression in a variety of established B-cell lines representing different stages of B-cell development has suggested a constitutive, B-cell-specific expression pattern. Because they are germinal center derived, L&H cells in nodular lymphocyte predominant Hodgkin lymphoma are consistenty immunoreactive for BOB.1. Conversely, the Hodgkin/Reed- Sternberg cells in classical Hodgkin lymphoma either do not express both (80%) or express only one (20%) of the two proteins. In B-cell lymphomas, the highest expression levels for BOB.1/OBF.1 are reported in follicular center lymphomas, diffuse large B-cell lymphomas and Burkitt lymphomas.B-CLL, MALT-type, and mantle cell lymphomas score negative or display an heterogenous/weaker reactivity.10-11 Studies have suggested that anti-BOB. has a high predictive value in discriminating primary mediastinal B-cell lymphoma from classical Hodgkin disease.Approximately 50% of acute myeloid leukemias express BOB.1.

The World Health Organization (WHO) classification of Hodgkin lymphoma (HL) distinguishes two types: Classical Hodgkin lymphoma (CHL) and nodular lymphocyte predominant Hodgkin lymphoma (NLPHL). Both groups have in common that they mostly derive from B cells with rare classical cases

The BOB.1/OBF.1/OCAB.1 protein is a lymphocyte-specific transcriptional coactivator. It interacts with the Oct1 and Oct2 transcription factors and contributes to the transcriptional activity of octamer motifs. The analysis of established B cell lines had suggested that BOB.1/OBF.1 is constitutively expressed

Oct1 and Oct2 are transcription factors of the POU homeo-domain family that bind to the Ig gene octamer sites, regulating B-cell-specific genes. The function of these transcription factors is dependent on the activity of B-cell-restricted coactivators such as BOB.1/OBF.1. Independent

In contrast to the tumor cells (L&H cells) of lymphocyte predominant Hodgkin disease (LPHD), Hodgkin and Reed-Sternberg (HRS) cells of classical Hodgkin disease (cHD) are unable to transcribe immunoglobulin, despite the presence of rearranged immunoglobulin genes. Although initial studies have
