Time of synthesis and cellular location of Epstein-Barr virus-specified polypeptides radioimmunoprecipitated from iododeoxyuridine-induced Burkitt lymphoma/somatic cell hybrids. 1982

J M Durnford, and P A Scanlon, and R Glaser

The Burkitt lymphoma/somatic cell hybrid D98/HR-1 contains repressed Epstein-Barr virus (EBV) genomes which can be induced by 5-iodo-2'-deoxyuridine (IdUrd) to express the EBV early antigen (EA) and the virus capsid antigen (VCA). Nuclear and cytoplasmic fractions prepared from uninduced, partially induced and fully induced hybrid cells were radioimmunoprecipitated with human sera having high antibody titres against EA and VCA. Three polypeptides, with mol. wt. 127 x 10(3), 115 x 10(3) and 84 x 10(3) (127K, 115K and 84K), were detected in cells induced to express EA. All three polypeptides continued to be synthesized late in infection. One of the polypeptides was predominantly nuclear, one predominantly cytoplasmic, and one found in both fractions. Three polypeptides, with mol. wt. 144K, 137K and 50K, were detectable only in cells induced to express both EA and VCA. All three polypeptides were found predominantly in the nuclear fraction.

D002051	Burkitt Lymphoma	A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.

D002467	Cell Nucleus	Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)	Cell Nuclei,Nuclei, Cell,Nucleus, Cell

D004854	Herpesvirus 4, Human	The type species of LYMPHOCRYPTOVIRUS, subfamily GAMMAHERPESVIRINAE, infecting B-cells in humans. It is thought to be the causative agent of INFECTIOUS MONONUCLEOSIS and is strongly associated with oral hairy leukoplakia (LEUKOPLAKIA, HAIRY;), BURKITT LYMPHOMA; and other malignancies.
