(Submitter supplied) We report the genome wide binding sites of BAP1, HCF1 and OGT in bone marrow derived macrophages. De-ubiquitinating enzyme BAP1 is mutated in a hereditary cancer syndrome with increased risk of mesothelioma and uveal melanoma. Somatic BAP1 mutations occur in various malignancies. We show that mouse Bap1 gene deletion is lethal during embryogenesis, but systemic or hematopoietic-restricted deletion in adults recapitulates features of human myelodysplastic syndrome (MDS). more...

(Submitter supplied) Analysis of sorted granulocyte macrophage progenitors (GMPs) in control and Bap1-deficient bone marrow cells. Loss of Bap1 in the hematopoietic compartments results in an MDS-like disease. These data allow for the examination of the genetic underpinnings of Bap1 loss in disease.

(Submitter supplied) BAP1 and ASXL1 interact to form a polycomb deubiquitinase complex that removes monoubiquitin from histone H2A lysine 119 (H2AK119Ub). However, BAP1 and ASXL1 are mutated in distinct cancer types, consistent with independent roles in regulating epigenetic state and malignant transformation. Here we demonstrate that Bap1 loss results in increased trimethylated histone H3 lysine 27 (H3K27me3), elevated Ezh2 expression, and enhanced repression of Polycomb Repressive Complex 2 (PRC2) targets. more...

(Submitter supplied) The deubiquitinase BAP1 is a candidate tumor suppressor regulating cell proliferation in human and is required for development in Drosophila. BAP1 is assembled into high molecular weight transcriptional multi-protein complexes. In order to identify potential BAP1 target genes, global mRNA expression profiling using microarrays was conducted.

(Submitter supplied) To identify target genes of mutant ASXL1 and BAP1 in hematopoietic cells, we performed RNA-seq using murine c-kit positive cells transduced with ASXL1-MT (MT) or ASXL1-MT-K351R (KR) together with vector or BAP1. Method：Murine c-kit positive bone marrow cells were transduced with ASXL1-MT (MT) or ASXL1-MT-K351R (KR) (coexpressing blastcidin resistant gene) together with vector or BAP1 (coexpressing puromycin resistant gene). more...

(Submitter supplied) ASXL1 is the obligate regulatory subunit of a deubiquitinase complex whose catalytic subunit is BAP1. Heterozygous mutations of ASXL1 that result in premature truncations are frequent in myeloid leukemias and Bohring-Opitz syndrome. Here, we demonstrate that truncated ASXL1 proteins confer enhanced activity on the ASXL1-BAP1 complex. Stable expression of truncated, hyperactive ASXL1-BAP1 complexes in a hematopoietic precursor cell line resulted in global erasure of H2AK119Ub, striking depletion of H3K27me3, selective upregulation of a subset of genes whose promoters bore both H2AK119Ub and H3K4me3, and spontaneous differentiation to the mast cell lineage. more...

(Submitter supplied) Uveal melanoma is a highly aggressive cancer with a strong propensity for metastasis, yet little is known about the biological mechanisms underlying this metastatic potential. We recently showed that most metastasizing uveal melanomas, which exhibit a class 2 gene expression profile, contain inactivating mutations in the tumor suppressor BAP1. The aim of this study was to investigate the role of BAP1 in uveal melanoma progression. more...

(Submitter supplied) BACKGROUND: Our previous studies showed that RUNX1 and ASXL1 mutations were frequently co-existed in chronic myelomonocytic leukemia (CMML) and clonal evolution of RUNX1 and/or ASXL1 occurred most frequently in chronic myeloid leukemia (CML) with myeloid blastic crisis. The molecular pathogenesis of cooperation of RUNX1 and ASXL1 mutations has not been reported yet. METHODS: Lentiviral-mediated stable transduction of RUNX1-WT/MT (R135T) in K562 cells which harboring ASXL1-MT (Y591X). more...

(Submitter supplied) We performed morpholino-mediated knockdown of Bap1 protein expression in Xenopus laevis developing embryos, and analyzed inhibiting and activating histone marks . We find that inhibition of Bap1 leads to decrease in H3K27AC activating makrs around lineage commitment genes, and increased global methylation.

(Submitter supplied) Recurrent somatic ASXL1 mutations occur in patients with myelodysplasia (MDS), myeloproliferative neoplasms (MPN), and acute myeloid leukemia (AML), and are associated with adverse outcome. Despite the genetic and clinical data implicating ASXL1 mutations in myeloid malignancies, the mechanisms of transformation by ASXL1 mutations are not understood. Here we identify that ASXL1 mutations result in loss of PRC2-mediated histone H3 lysine 27 (H3K27) tri-methylation. more...

(Submitter supplied) BAP1 deletion in primary mouse epidermal cell culture leads to increased melanocytes population. However, it is unclear whether BAP1 exhibits its function in melanocytes or in the progenitor cells for melanocytes, since the epidermal culture contains a mixed cell types. We aim to carry out a single cell RNAseq profiling with this system, and dissect BAP1's roles in different cell types.

(Submitter supplied) Malignancies arising from mutation of tumor suppressor genes display an unexplained tissue proclivity. For example, tumor suppressor BAP1 encodes a ubiquitously expressed deubiquitinase for histone H2A but germline mutations predominantly cause uveal melanomas and mesotheliomas. We show that BAP1 inactivation causes apoptosis in mouse embryonic stem cells, fibroblasts, liver and pancreas, whereas melanocytes and mesothelial cells remain viable. more...
