Descripción

Descripción general

Octamer-binding transcription factor-2 (Oct-2) is a transcription factor of the POU homeo-domain family. It binds to Ig gene octamer sites and plays a crucial role in B-cell development and differentiation, as well as in B-cell identity. Oct-2 is expressed in a subset of normal B-lymphocytes and is expressed in various B-cell lymphomas as well as nodular lymphocyte predominant Hodgkin lymphoma, while it is typically not expressed in the Reed–Sternberg and Hodgkin (RS/H) cells of classical Hodgkin lymphoma.


Oct-2 is a transcription factor of the POU homeo-domain family that binds to the Ig gene octamer sites, regulating B-cell-specific genes. These are involved in proliferation and differentiation and despite the scarce evidence for Oct-2 expression in T cells, it has been shown that this factor participates in transcriptional regulation during T-cell activation. Oct-2 activity is dependent on phosphorylation and alternatitive splicing, although it seems that the level of its expression can be used as a marker of B-cell lineage and differentiation. The following show high levels of Oct-2 expression: germinal center B-cells, mantle B-cells, monocytoid B-cells, and plasma cells. Various lymphomas are also positive for this marker including the following: B-chronic lymphocytic leukemia, mantle cell lymphoma, follicular lymphoma, marginal zone lymphoma, plasmacytoma, Burkitt lymphoma, diffuse large cell lymphoma, diffuse large B-cell lymphoma, T-cell rich B-cell lymphoma, nodular lymphocyte predominant Hodgkin lymphoma, classic Hodgkin lymphoma.

Several studies of Oct-2 expression have shown a low level expression in pre-B, T-cell, myelomonocytic, and epithelial cell lines, whereas all mature B-cell lines display high levels of expression. Analysis of Oct-2 expression in primary Hodgkin’s lymphoma (HLs) and cell lines derived from it showed that the tumor cells analyzed had high levels of expression and activity, suggesting a common B-cell origin for all types of HLs.
