Increased expression of brother of the regulator of imprinted sites in peripheral blood neutrophils is associated with both benign and malignant breast lesions.

Background: BORIS, a paralog of the multifunctional CCCTC-binding factor (CTCF) gene is restricted to testis and normally not present in females. It is aberrantly activated in various human cancers including cancer breast. Using immunohistochemistry, western blot and/or RT-PCR, significantly higher levels of BORIS expression were reported in the neutrophils of cancer breast patients.

Adhesion molecules expression in CLL: Potential impact on clinical and hematological parameters.

Background: B-cell chronic lymphocytic leukemia (CLL) is marked by the accumulation of CD5+ B lymphocytes within the blood, bone marrow (BM), and secondary lymphoid tissues. Abnormalities in the expression and function of cell adhesion molecules may account for the patterns of intra-nodal growth and hematogenous spread of the malignant cells. Chemokines and integrin-mediated adhesion and trans-endothelial migration (TEM) are central aspects in trafficking and retention of hematopoietic cells in the BM and lymphoid organs.
