Role of the nuclear deubiquitinase BAP1 in the pathogenesis of mesothelioma.

In this article, transcriptional deregulation, mediated by inactivation of the nuclear deubiquitinase BAP1, is implicated in the pathogenesis of mesothelioma.  The two most common known genetic alterations in mesotheliomas are 9p21 deletions on CDKN2A and 22q deletions causing NF2 loss. The authors show that another gene with a high rate of non-synonymous mutations is BAP1 (encoding BRCA1-associated protein 1).  Somatic mutations were found in 23% of mesotheliomas.  The study also shows that other common tumor suppressors, such as PTEN and p53, showed few or no mutations, confirming data from previous …
