Simian virus 40 is present in most United States human mesotheliomas, but it is rarely present in non-Hodgkin's lymphoma
…hamsters. In humans, SV40 has been detected in tumors of the first four types. Using the polymerase chain reaction (PCR), we tested 29 non-Hodgkin's lymphomas (intermediate and high-grade), 25 posttransplant lymphoproliferative disorders, and…

The Suppressed Induction of Human Mature Cytotoxic T Lymphocytes Caused by Asbestos Is Not due to Interleukin-2 Insufficiency
We previously reported that exposure to chrysotile B (CB) asbestos suppressed the induction of mature cytotoxic T lymphocytes (CTLs) during mixed lymphocyte reaction assays (MLRs) with a decrease in the proliferation of immature CTLs. However, the…

DNA copy number gains in malignant pleural mesothelioma
…The molecular pathogenesis of MPM remains unclear. The present study analyzed the frequency of various genomic copy number gains (CNGs) in MPM using reverse transcription-quantitative polymerase chain reaction. A total of 83 primary MPMs and…

Effect of asbestos exposure on differentiation and function of cytotoxic T lymphocytes
…naïve CD8+ T cells following antigen stimulation. Exposure to chrysotile B asbestos suppressed the differentiation of CTLs during the mixed lymphocyte reaction (MLR) and was associated with a decrease in proliferation of CD8+ T cells. Additionally…

Silicosis and autoimmunity
…Although the importance of the NACHT, LRR and PYD domains-containing protein 3 (NALP3) inflammasome as the initial immune reaction against silica particles has been identified, the mechanisms involved that lead to various autoimmune diseases in…

VEGF and VEGF type C play an important role in angiogenesis and lymphangiogenesis in human malignant mesothelioma tumours
…cell lines, 54 MPM tumours and five normal pleural tissues. Expression levels for receptors and ligands were assessed by semiquantitative reverse transcriptase polymerase chain reaction analysis. Microvessels were highlighted by immunohistochemical staining for factor VIII. The…

Human mesotheliomas contain the simian virus-40 regulatory region and large tumor antigen DNA sequences
…40-induced hamster mesothelioma tumor H9A. Polymerase chain reaction primers were used to amplify various simian virus 40 large T-antigen regions including a 105-base pair amino terminus fragment, a 281-base pair carboxyl terminus…

Overexpression of EPH receptor B2 in malignant mesothelioma correlates with oncogenic behavior
…we investigated EPHB2 in MM tumors compared with normal mesothelium. EPHB2 and downstream target expression were evaluated using reverse-transcriptase polymerase chain reaction and immunoblotting methods. The biological significance of EPHB2 in MM was evaluated using…
