BAP1 regulates HSF1 activity and cancer immunity in pancreatic cancer. (PubMed, J Exp Clin Cancer Res)

Our study elucidates an unrevealed mechanism by which BAP1 regulates immune therapy response in PDAC via HSF1 inhibition, and providing promising therapeutic strategies to address immune insensitivity in BAP1-deficient PDAC.

BAP31 Promotes Adhesion Between Endothelial Cells and Macrophages Through the NF-κB Signaling Pathway in Sepsis. (PubMed, J Inflamm Res)

BAP31 up-regulated the expressions of ICAM1 and VCAM1 in endothelial cells leading to sepsis-associated organ injury. This may be involved in activation of TLR signaling pathway, TAK1 pathway, and PI3K-AKT signaling pathway.

Multi-omics comparison of malignant and normal uveal melanocytes reveals molecular features of uveal melanoma. (PubMed, Cell Rep)

Hi-C revealed chromatin topology changes associated with the upregulation of PRAME, an independent prognostic biomarker in UM, and a potential therapeutic target. Our findings illustrate how multi-omics approaches can improve our understanding of tumorigenesis and reveal two distinct mechanisms of gene expression dysregulation in UM.

RITA selectively inhibits proliferation of BAP1-deficient cutaneous melanoma cells in vitro (PubMed, Nan Fang Yi Ke Da Xue Xue Bao)

Loss of BAP1 results in the sensitivity of cutaneous melanoma cells to p53 activator RITA. In melanoma cells, the activity of ubiquitinase in BAP1 is directly related to their sensitivity to RITA. An increased expression of p53 protein induced by BAP1 knockout is probably a key reason for RITA sensitivity of melanoma cells, suggesting the potential of RITA as a targeted therapeutic agent for cutaneous melanoma carrying BAP1-inactivating mutations.

Mullerian adenosarcoma: clinicopathologic and molecular characterization highlighting recurrent BAP1 loss and distinctive features of high-grade tumors. (PubMed, Mod Pathol)

Notably, out of 196 mesenchymal neoplasms of gynecologic origin, BAP1 homozygous deletion was only found in adenosarcomas (P = 0.0003). This study demonstrates that high-grade adenosarcomas are heterogeneous at the molecular level and are characterized by genomic instability and TP53 mutations; ATRX loss may be involved in high-grade transformation of low-grade adenosarcoma; and BAP1 inactivation appears to be a specific pathogenic driver in a subset of adenosarcomas.

BAP1-defficient breast cancer in a patient with BAP1 cancer syndrome. (PubMed, Breast Cancer)

As her triple negative tumor was shown to be PD-L1 positive, the patient was treated with combination of atezolizumab and nab-paclitaxel. This case strengthens the evidence for including breast cancer in the BAP1 cancer syndrome tumor spectrum with implications for future cancer prevention programs. It also indicates immune checkpoint inhibitors might prove to be an effective treatment for BAP1-deficient breast cancer.

Through a survey of biomarkers in 124 cases MPM at Pham Ngoc Thach Hospital from 2015-2019 we have brought the following statements: For diagnosis: There is evidence of presence of asbestos body and SV-40 and the IHC markers of Calretinin, Glut-1 and WT-1 have been the highest expressions in the cases of MPM and have been the best values in epidemiological diagnosis and positive diagnosis of MPM. For treatment: The most important gene expressions have been p16 Deletion and BAP1 and a positive PD-L1 ratio with two markers: 22C3 and SP263. This also leads to the possibility of targeted application and immunotherapy for MPM.

A total of 269 up-regulated and 807 down-regulated genes were identified from the combined GSE110193 and GSE48863 data sets...The potential targets of BAP1 include CXCL8, COL5A3, COL11A1, and COL12A1. It is believed that BAP1 regulates UVM cell adhesion through these four genes and ultimately regulates tumor development and migration.

Sarcomatoid Mesothelioma: A CDKN2A molecular analysis of 53 cases with immunohistochemical correlation with BAP1. (PubMed, Pathol Res Pract)

Our findings showed that even though the use of BAP1 and p16 are important tools in the diagnosis of mesothelioma, a proportion of cases still remains negative with approximately 30 % of the cases in which the concordance of BAP1 loss and p16 homozygous deletion will not be present. We consider that the final diagnosis of mesothelioma is best accomplished by a global interpretation of clinical, radiographic, and pathological features including immunohistochemistry and molecular studies.

Inactivation of Bap1 Cooperates with Losses of Nf2 and Cdkn2a to Drive the Development of Pleural Malignant Mesothelioma in Conditional Mouse Models. (PubMed, Cancer Res)

RNA-seq analysis of MMs from triple-CKO mice revealed enrichment of genes transcriptionally regulated by the polycomb repressive complex 2 (PRC2) and others previously implicated in known Bap1-related cellular processes. These data demonstrate that somatic inactivation of Bap1, Nf2, and Cdkn2a results in rapid, aggressive MMs, and that deletion of Bap1 contributes to tumor development, in part, by loss of PRC2-mediated gene repression of tumorigenic target genes and by acquisition of stem-cell potential, suggesting a potential avenue for therapeutic intervention.

MPM cells with BAP1 loss or 9p21 HD exhibited significantly more frequent cell-in-cell engulfment, multinucleation, and larger multicellular clusters composed of more than 10 cells than reactive mesothelial cells. In conclusion, MPM cells with BAP1 loss or 9p21 HD share similar cytological features, indicating that the same morphological criteria can be used to detect MPM cells harboring such genetic aberrations.
