Adenosine deaminase activity in lymphocyte subpopulations of B-16 melanoma and normal C57BL bearing mice. 1984

B Shohat, and G Agam, and S Brosh, and O Sperling, and N Sharon

The activity of adenosine deaminase (ADA) was measured in thymus and spleen subpopulations separated by peanut agglutinin (PNA) of melanoma B-16 C57BL bearing mice and normal age-matched C57BL mice. Groups of 10 mice were used each time and the experiments were repeated 6 times. The adenosine deaminase activity in the PNA+ thymocytes of B-16 bearing mice was about 2.5 times lower than that of the normal C57BL mice while the ADA activity in the PNA+ fraction of spleen of the B-16 melanoma bearing mice was 2.5 times higher. These results demonstrate that the tumor burden probably induces a different redistribution and traffic of lymphocytes from one lymphopoietic organ to another. This traffic can also explain the thymus involution and spleen enlargement found in the B-16 mice.

UI MeSH Term Description Entries
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D009700 Nucleoside Deaminases Catalyze the hydrolysis of nucleosides with the elimination of ammonia. Deaminases, Nucleoside
D000243 Adenosine Deaminase An enzyme that catalyzes the hydrolysis of ADENOSINE to INOSINE with the elimination of AMMONIA. Adenosine Aminohydrolase,Aminohydrolase, Adenosine,Deaminase, Adenosine
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013154 Spleen An encapsulated lymphatic organ through which venous blood filters.
D013950 Thymus Gland A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.
