一般說明
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

Expression patterns of eight transcription factors involved in different stages of B-cell development were investigated in a large group of primary cutaneous B-cell lymphomas and compared with expression patterns during normal B-cell development. The following transcription factors were investigated: Pax-5
