High Incidence of Somatic BAP1 Alterations in Sporadic Malignant Mesothelioma

High Incidence of Somatic BAP1 Alterations in Sporadic Malignant Mesothelioma

The BAP1 gene should be targeted to develop specific therapies for mesothelioma

Genetic mutations can be inherited at birth, and some of them cause disease and cancer, such as the BAP1 cancer syndrome. Alternatively, the same genes or others can become mutated in cancer cells.  Most mutations found in cancer cells are acquired during tumor growth and do not play a critical role in tumor initiation or growth. Some mutations, instead, are called driver mutations because they drive tumor growth.  Driver mutations are usually frequent in a given tumor type.

 

We found that BAP1 is the most commonly acquired mutation in sporadic mesothelioma, which means mesothelioma that does not occur because of inherited germline mutation (for example, mesothelioma caused by asbestos exposure).  We found that over 60% of sporadic mesotheliomas have mutated BAP1. This finding underscores the critical role of BAP1 in mesothelioma and points to BAP1 as the critical gene that should be targeted to develop specific therapies for mesothelioma. Our findings have been validated by several other independent studies, including those of Drs. Harvey Pass, Rafael Bueno, Giorgio Scagliotti, and others, which are reviewed in The Journal of Thoracic Oncology publication
Recent insights emerging from malignant mesothelioma genome sequencing.

Minimal asbestos exposure in germline BAP1 heterozygous mice is associated with deregulated inflammatory response and increased risk of mesothelioma

Minimal asbestos exposure in germline BAP1 heterozygous mice is associated with deregulated inflammatory response and increased risk of mesothelioma

Oncogene - Short Communication

Germline BAP1 mutations predispose to several cancers, in particular malignant mesothelioma. Mesothelioma is an aggressive malignancy generally associated with professional exposure to asbestos. However, to date, we found that none of the mesothelioma patients carrying germline BAP1 mutations were professionally exposed to asbestos

HMGB1 and its hyper-acetylated isoform are sensitive and specific serum biomarkers to detect asbestos exposure and to identify mesothelioma patients

HMGB1 and its hyper-acetylated isoform are sensitive and specific serum biomarkers to detect asbestos exposure and to identify mesothelioma patients

This study shows that hyper-acetylated HMGB1 is an accurate biomarker to differentiate malignant mesothelioma patients from individuals occupationally exposed to asbestos and unexposed controls. A trial to independently validate these findings will start soon.

Combined Genetic and Genealogic Studies Uncover a Large BAP1 Cancer Syndrome Kindred Tracing Back Nine Generations to a Common Ancestor from the 1700s

Combined Genetic and Genealogic Studies Uncover a Large BAP1 Cancer Syndrome Kindred Tracing Back Nine Generations to a Common Ancestor from the 1700s

Our multinational team discovered that four apparently unrelated US families share a common ancestor, a couple who immigrated from Germany in the early 1700s.

Latest developments in our understanding of the pathogenesis of mesothelioma and the design of targeted therapies

Latest developments in our understanding of the pathogenesis of mesothelioma and the design of targeted therapies

Online journal: Expert Review of Respiratory Medicine

Malignant mesothelioma is an aggressive cancer whose pathogenesis is causally linked to occupational exposure to asbestos. Familial clusters of mesotheliomas have been observed in settings of genetic predisposition. Mesothelioma incidence is anticipated to increase worldwide in the next two decades. Novel treatments are needed, as current treatment modalities may improve the quality of life, but have shown modest effects in improving overall survival. Increasing knowledge on the molecular characteristics of mesothelioma has led to the development of novel potential therapeutic strategies, including: molecular targeted approaches, that is the inhibition of vascular endothelial growth factor with bevacizumab; immunotherapy with chimeric monoclonal antibody, immunotoxin, antibody drug conjugate, vaccine and viruses; inhibition of asbestos-induced inflammation, that is aspirin inhibition of HMGB1 activity may decrease or delay mesothelioma onset and/or growth. We elaborate on the rationale behind new therapeutic strategies, and summarize available preclinical and clinical results, as well as efforts still ongoing.
