| Research Abstract |
We established twelve malignant pleural mesothelioma(MPM) cell lines from Japanese patients. We detected homozygous deletion of p16^<INK4A>/p14^<ARF> in all MPM cell lines. However, mutations of other tumor suppressor genes, including TP53, and protooncogenes, including KRAS, NRAS, BRAF, EGFR and HER2, were not found in these cell lines. Two women who had no history of asbestos exposure showed lower concentrations of crysotile and amphibole asbestos than the control subject. On the other hand, most patients with a history of asbestos exposure had higher concentrations of crysotile and amphibole asbestos than the control subject, but even in some patients with a history of asbestos exposure the low concentrations were observed. To elucidate the relation between the pulmonary asbestos fiber concentrations by fiber types and development of MPM, further investigations are necessary.
