Abstract

Expression of the intercellular adhesion molecule-1 (CD54) as well as the mutations of p53 gene were studied in childhood Burkitt's lymphoma (BL). Expression of CD54 was identified in 6 of 15 fresh BL cases. Mutations of p53 gene, analyzed by polymerase chain reaction-single stranded chain polymorphism followed by sequencing, were found in 5 of 14 cases examined. Interestingly, all the cases with p53 mutation were CD54 negative. This high frequency of p53 mutation in the CD54 negative group prompted us to analyze the clinical features of these cases. Six of 15 cases died within 21 months after initiation of therapy and five of these were CD54 negative. In addition, four of these had p53 mutation. These results suggest that the lack of CD54 by BL cells may provide the background for the mutation of p53 gene to occur which could result in the transformation to a more aggressive phenotype.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.

CNS Lymphoma

In CNS lymphoma, cancerous cells from lymph tissues or other parts of the body form tumors in the brain and/or spinal cord. Here is the latest research on this rare non-Hodgkin lymphoma.
