Characterization of Proliferating Compartment in B-Cell Patients and in Healthy Aging Subjects

2014-08-27 03:14:11 | BioPortfolio

Summary

By ingesting a non-radioactive and non-toxic compound "heavy water" for 6 weeks, the DNA of newly developed cells in the body of subjects with B-cell chronic lymphocytic leukemia can be labeled and followed by performing routine blood draws at specified time intervals. By using mass spectrometric analysis we can measure how quickly new B-CLL cells are generated in the bone marrow and how quickly they leave the blood, a measure of cell turnover. This will help us to better understand the unique characteristics of this disease process.

Medical and Biotech [MESH] Definitions

A chronic leukemia characterized by abnormal B-lymphocytes and often generalized lymphadenopathy. In patients presenting predominately with blood and bone marrow involvement it is called chronic lymphocytic leukemia (CLL); in those predominately with enlarged lymph nodes it is called small lymphocytic lymphoma. These terms represent spectrums of the same disease.

A chronic leukemia characterized by a large number of circulating prolymphocytes. It can arise spontaneously or as a consequence of transformation of CHRONIC LYMPHOCYTIC LEUKEMIA.

A lymphoid leukemia characterized by a profound LYMPHOCYTOSIS with or without LYMPHADENOPATHY, hepatosplenomegaly, frequently rapid progression, and short survival. It was formerly called T-cell chronic lymphocytic leukemia.

A pathologic change in leukemia in which leukemic cells permeate various organs at any stage of the disease. All types of leukemia show various degrees of infiltration, depending upon the type of leukemia. The degree of infiltration may vary from site to site. The liver and spleen are common sites of infiltration, the greatest appearing in myelocytic leukemia, but infiltration is seen also in the granulocytic and lymphocytic types. The kidney is also a common site and of the gastrointestinal system, the stomach and ileum are commonly involved. In lymphocytic leukemia the skin is often infiltrated. The central nervous system too is a common site.

A basic helix-loop-helix transcription factor that plays a critical role in HEMATOPOIESIS and as a positive regulator in the differentiation of ERYTHROID CELLS. Chromosome translocations involving the TAL-1 gene are associated with T-CELL ACUTE LYMPHOCYTIC LEUKEMIA.
