Inactivation of Bap1 Cooperates with Losses of Nf2 and Cdkn2a to Drive the Development of Pleural Malignant Mesothelioma in Conditional Mouse Models

Project description:Mutations/deletions of BAP1, CDKN2A, and NF2 are the most frequent genetic lesions in human MM. We introduced various combinations of these deletions in the pleura of conditional knockout (CKO) mice, focusing on the contribution of Bap1 loss.

Chromosomal aberration of malignant pleural mesothelioma cell lines

Project description:To identify regions that display DNA copy number alterations in malignant pleural mesothelioma (MPM), we carried out array comparative genomic hybridization (CGH) analysis with 14 MPM cell lines. Regions of genomic aberrations observed in >20% of individuals were 9p21.3, 13q12.11, 16p13, and 22q12.2 of losses. The most frequent alteration was 9p21.3, which include the p16INK4/p14ARF. The loss of 22q12.2 regions include the NF2 was observed in 3 out of 14 cell lines. In 3 cell lines, loss of 13q12.11 region which contains Large Tumor Suppressor, homolog 2 (LATS2) was detected. Human malignant pleural mesothelioma cell lines were profiled on Agilent 244K aCGH arrays according to manufacturer’s instructions. Pooled normal human genomic DNA was used as the reference.

Mesothelioma tumor aCGH profiles

Project description:Malignant pleural mesotheliomas (MPMs) often show CDKN2A and NF2 inactivation but other highly recurrent mutations have not been described. To identify additional driver genes, we used an integrated genomic analysis of 53 MPM tumor samples to guide a focused sequencing effort that uncovered somatic inactivating mutations in BAP1 in 23% of MPM. The BAP1 nuclear deubiquitinase is known to target histones (together with ASXL1 as a Polycomb repressor subunit) and the HCF1 transcriptional co-factor, and we show that BAP1 knockdown in MPM cell lines affects E2F and Polycomb target genes. These findings implicate transcriptional deregulation in the pathogenesis of MPM. DNA from 53 malignant pleural mesothelioma tumors was collected and hybridized to aCGH arrays. Data were analyzed to create gain and loss profiles for each tumor. This submission includes gcNormalized-data.

Genomic DNA was harvested from untreated malignant pleural mesothelioma (MPM) cell lines and used to generate gain/loss profiles for each line using aCGH.

Copy number variations analysis by CytoscanHD array of 33 human pleural mesothelioma cell lines

Project description:We performed a cytoscanHD array to analyze copy number variations in the genome of 33 human pleural mesothelioma cell lines established from patient pleural effusion. We were particularly interested in the analysis of the p21.3 region of chromosome 9 which contains CDKN2A tumor suppressor genes and the gene encoding type I interferons that are often deleted and confer sensitivity to oncolytic Measles virus

Inactivation of p21-Activated Kinase 2 (Pak2) Inhibits the Development of Nf2-Deficient Tumors by Restricting Downstream Hedgehog and Wnt Signaling

Project description:Since loss of the NF2 tumor suppressor gene results in p21-activated kinase (Pak) activation, PAK inhibitors hold promise for the treatment of NF2-deficient tumors. To test this possibility, we asked if loss of Pak2, a highly expressed group I PAK member, affects the development of malignant mesothelioma in Nf2;Cdkn2a-deficient (NC) mice and the growth properties of NC mesothelioma cells in culture. In vivo, deletion of Pak2 resulted in a markedly decreased incidence and delayed onset of both pleural and peritoneal malignant mesotheliomas in NC mice. In vitro, Pak2 deletion decreased malignant mesothelioma cell viability, migration, clonogenicity, and spheroid formation. RNA-seq analysis demonstrated downregulated expression of Hedgehog and Wnt pathway genes in NC;Pak2-/- mesothelioma cells versus NC;Pak2+/+ mesothelioma cells. Targeting of the Hedgehog signaling component Gli1 or its target gene Myc inhibited cell viability and spheroid formation in NC;P+/+ mesothelioma cells. Kinome profiling uncovered kinase changes indicative of EMT in NC;Pak2-/- mesothelioma cells, suggesting that Pak2-deficient malignant mesotheliomas can adapt by reprogramming their kinome in the absence of Pak activity. The identification of such compensatory pathways offers opportunities for rational combination therapies to circumvent resistance to anti-PAK drugs.
