First report of the unique expression of RECAF (receptor for alfa feto-protein) in adult B-NHL/CLL patients.

Background: Lymphoproliferative disorders (LPDs) are a heterogeneous group of diseases characterized by an uncontrolled production of monoclonal lymphocytes. RECAF is the receptor for alpha-fetoprotein, which is re-expressed on malignant cells, thus serving as a broad-spectrum tumor marker.

Methods: The current study is a retrospective study carried out on 200 archival bone marrow trephine biopsy specimens [60 normal control (NC), 38 pathological control (PC) and 102 lymphoproliferative diseases (LPD) specimens].

Correlation of telomerase activity to apoptosis and survival in adult acute lymphoblastic leukemia: an Egyptian single-center study.

Telomerase is activated in most tumors, but suppressed in normal human somatic cells. Current evidence indicates that telomerase reactivation is a critical step in carcinogenesis, with a close relationship to apoptosis. The goal of this study was to investigate the levels and relationship of telomerase activity to apoptosis and its impact on the survival of Egyptian adult acute lymphoblastic leukemia patients.
