EBV is a key risk factor for many malignancy diseases such as nasopharyngeal carcinoma (NPC) and Burkitt lymphoma (BL). EBV integration has been reported, but its scale and impact to cancer development is remains unclear. C666-1 (NPC cell line) and Raji (BL cell line) are commonly studied EBV-positive cancer cells. A rare few EBV integration sites in Raji were found in previous research by trad...

Results Anti-CD20-hIFNa induced stronger growth inhibition than rituximab, particularly against Burkitt and germinal center-type DLBCL NHLs. Tumor growth inhibition by anti-CD20-hIFNa was associated with substantial apoptosis in some cell lines. Anti-CD20-hIFNa exhibited potent ADCC activity against Daudi, Ramos, and Raji cells, identical to rituximab. Surprisingly, anti-CD20-hIFNa exhibited su...

A 65,000-dalton (65K) antigen found in Raji cells by fluoroimmunoelectrophoresis and radioimmunoelectrophoresis has been identified as an Epstein-Barr virus nuclear antigen (EBNA). This identification is based on the following evidence. The 65K antigen is detected in Raji cells but not in three Epstein-Barr virus (-) human B cell lines. It is not detected with EBNA (-) sera. The 65K antigen is ...

CD48 is a cell surface, glycosylphosphatidylinositol-linked glycoprotein, and a potential target for treatment of leukemia and lymphoma. Two anti-CD48 mAbs, murine HuLy-m3 and human IgG1-N2A, were compared in cellular assays using a human lymphoma cell line (Raji) for their ability to inhibit cell growth and induce apoptosis. In vitro studies revealed both HuLy-m3 and IgG1-N2A mAbs were able to...

Apoptosis induced by rhodium II amidate, rhodium II propionate, cisplatin and interactions with dexamethaxone were studied on some human leukemia cell lines Raji, Jurkat and U937. Apoptosis was studied by flow cytometry, agarose gel electrophoresis and morphological analysis. Rhodium II propionate induced apoptosis in all the three cell lines, Rhodium II amidate, in the lymphoid cell lines Jurk...

A monoclonal antibody VCD-1, directed against the N-terminal intracellular part of the invariant chain (li) was used to show, by immunoprecipitation and Western blotting, the unprocessed and processed forms of li in chronic lymphocytic leukemia (CLL) cells, in Epstein-Barr virus-transformed normal lymphocytes (EBVL), and in cells of the Raji Burkitt's lymphoma cell line. Terminal glycosylation ...

PAX5 encodes a transcription factor essential for B-cell differentiation, and PAX5 haploinsufficiency is involved in tumorigenesis. There were few studies on how PAX5 haploinsufficiency regulated genes expression to promote tumorigenesis. In this study, we constructed the cell model of PAX5 haploinsufficiency using gene editing technology in Raji cells, detected differentially expressed genes i...

A commercial kit (Cordia-IC) from Cordis Laboratory, Miami, Fla., was compared with the Raji cell radioimmunoassay for its ability to detect circulating immune complexes (CIC) in sera from 30 control subjects and 118 patients with infectious diseases. The 118 patients were categorized into the following groups: (i) 23 patients with bacterial endocarditis, (ii) 41 patients with bacteremia from a...

Epstein-Barr virus obtained by superinfection of Raji cells with Epstein-Barr virus recovered from P3HR1 cells (HRI virus) transformed human lymphocytes, but it did not superinfect Raji cells. A human lymphoblastoid cell line, HLB, established by such transformation contained 22 Epstein-Barr virus genomes per cell and Epstein-Barr virus-associated nuclear antigen, and a few cells contained earl...

Curcumin has been documented to exert anticancer effects by interacting with altered proliferative and apoptotic pathways in cancer models. In this study, we evaluated the potential of curcumin to reverse promoter methylation of the p15 gene in Raji cells and its ability to induce apoptosis and genomic instability. Anti-neoplastic action of curcumin showed an augmentation in reactive oxygen spe...
