A Genetic Screening Identifies a Component of the SWI/SNF Complex, Arid1b As a Senescence Regulator

The use of RNA interference to identify genes with a role in senescence is an important tool in the discovery of novel cancer genes. In this work, a protocol was established for conducting bypass of senescence screenings, using shRNA libraries together with next-generation sequencing. Using this approach, the SWI/SNF subunit Arid1b was identified as a regulator of cellular lifespan in MEFs. SWI/SNF is a large multi-subunit complex that remodels chromatin. Mutations in SWI/SNF proteins are frequently associated with cancer, suggesting that SWI/SNF components are tumour suppressors. Here the role of ARID1B during senescence was investigated. Depletion of ARID1B extends the proliferative capacity of primary mouse and human fibroblasts. -
Aberrant Methylation Underlies Insulin Gene Expression in Human Insulinoma
ARTICLE https://doi.org/10.1038/s41467-020-18839-1 OPEN Aberrant methylation underlies insulin gene expression in human insulinoma Esra Karakose1,6, Huan Wang 2,6, William Inabnet1, Rajesh V.

Scott 1,7 & Luca Lambertini 1,6 1234567890():,; Human insulinomas are rare, benign, slowly proliferating, insulin-producing beta cell tumors that provide a molecular “recipe” or “roadmap” for pathways that control human beta cell regeneration. An earlier study revealed abnormal methylation in the imprinted p15.5-p15.4 region of chromosome 11, known to be abnormally methylated in another disorder of expanded beta cell mass and function: the focal variant of congenital hyperinsulinism. Here, we compare deep DNA methylome sequencing on 19 human insulinomas, and five sets of normal beta cells. We find a remarkably consistent, abnormal methylation pattern in insu- linomas. The findings suggest that abnormal insulin (INS) promoter methylation and altered transcription factor expression create alternative drivers of INS expression, replacing cano- nical PDX1-driven beta cell specification with a pathological, looping, distal enhancer-based form of transcriptional regulation. Finally, NFaT transcription factors, rather than the cano- nical PDX1 enhancer complex, are predicted to drive INS transactivation. 1 From the Diabetes Obesity and Metabolism Institute, The Department of Surgery, The Department of Pathology, The Department of Genetics and Genomics Sciences and The Institute for Genomics and Multiscale Biology, The Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA. -
Nucleoporin 107, 62 and 153 Mediate Kcnq1ot1 Imprinted Domain Regulation in Extraembryonic Endoderm Stem Cells
ARTICLE DOI: 10.1038/s41467-018-05208-2 OPEN Nucleoporin 107, 62 and 153 mediate Kcnq1ot1 imprinted domain regulation in extraembryonic endoderm stem cells Saqib S. Sachani 1,2,3,4, Lauren S. Landschoot1,2, Liyue Zhang1,2, Carlee R. White1,2, William A. MacDonald3,4, Michael C. Golding 5 & Mellissa R.W. Mann 3,4 1234567890():,; Genomic imprinting is a phenomenon that restricts transcription to predominantly one par- ental allele. How this transcriptional duality is regulated is poorly understood. Here we perform an RNA interference screen for epigenetic factors involved in paternal allelic silen- cing at the Kcnq1ot1 imprinted domain in mouse extraembryonic endoderm stem cells. Multiple factors are identified, including nucleoporin 107 (NUP107). To determine NUP107’s role and specificity in Kcnq1ot1 imprinted domain regulation, we deplete Nup107, as well as Nup62, Nup98/96 and Nup153. Nup107, Nup62 and Nup153, but not Nup98/96 depletion, reduce Kcnq1ot1 noncoding RNA volume, displace the Kcnq1ot1 domain from the nuclear periphery, reactivate a subset of normally silent paternal alleles in the domain, alter histone modifications with concomitant changes in KMT2A, EZH2 and EHMT2 occupancy, as well as reduce cohesin interactions at the Kcnq1ot1 imprinting control region. Our results establish an important role for specific nucleoporins in mediating Kcnq1ot1 imprinted domain regulation. 1 Departments of Obstetrics & Gynaecology, and Biochemistry, Western University, Schulich School of Medicine and Dentistry, London, ON N6A 5W9, Canada. 2 Children’s Health Research Institute, London, ON N6C 2V5, Canada. 3 Departments of Obstetrics, Gynecology and Reproductive Sciences, University of Pittsburgh School of Medicine, Pittsburgh, PA 15213, USA. 4 Magee-Womens Research Institute, Pittsburgh, PA 15213, USA. -
Mir-338-3P Functions As a Tumor Suppressor in Gastric Cancer by Targeting PTP1B
Sun et al. Cell Death and Disease DOI 10.1038/s41419-018-0611-0 Cell Death & Disease ARTICLE Open Access miR-338-3p functions as a tumor suppressor in gastric cancer by targeting PTP1B Feng Sun1, Mengchao Yu2,JingYu2, Zhijian Liu1,XinyanZhou2,YanqingLiu2, Xiaolong Ge3,HaidongGao2, Mei Li4, Xiaohong Jiang2,SongLiu1,XiChen2 and Wenxian Guan 1 Abstract Gastric cancer (GC) is one of the most common malignant tumors and peritoneal metastasis is the primary cause for advanced GC’s mortality. Protein-tyrosine phosphatase 1B (PTP1B) functions as an oncogene and involves in carcinogenesis and cancer dissemination. However, the function and regulation of PTP1B in GC remain poorly understood. In this study, we found that PTP1B was upregulated in GC tissues and overexpression of PTP1B in vitro promoted cell migration and prevented apoptosis. Then, we predicted that PTP1B was a target of miR-338-3p and we revealed an inverse correlation between miR-338-3p levels and PTP1B protein levels in GC tissues. Next, we verified that PTP1B was inhibited by miR-338-3p via direct targeting to its 3′-untranslated regions. Moreover, overexpression of miR-338-3p in vitro attenuated GC cell migration and promoted apoptosis, and these effects could be partially reversed by reintroduction of PTP1B. Finally, we established an orthotopic xenograft model and a peritoneal dissemination model of GC to demonstrate that miR-338-3p restrained tumor growth and dissemination in vivo by targeting PTP1B. Taken together, our results highlight that PTP1B is an oncogene and is negatively regulated by miR- 1234567890():,; 1234567890():,; 338-3p in GC, which may provide new insights into novel molecular therapeutic targets for GC. -

BAP1: Case Report and Insight Into a Novel Tumor Suppressor Kanad Ghosh1, Badri Modi2, William D
Ghosh et al. BMC Dermatology (2017) 17:13 DOI 10.1186/s12895-017-0065-6 CASEREPORT Open Access BAP1: case report and insight into a novel tumor suppressor Kanad Ghosh1, Badri Modi2, William D. James2 and Brian C. Capell1,2,3* Abstract Background: BRCA1-Associated-Protein 1 (BAP1) is a dynamic tumor suppressor which, when mutated, has been associated with an increased risk of uveal melanoma, cutaneous melanoma, mesothelioma, and several other cancers. Germline BAP1 mutations have been extensively studied, where they have been found to cause hereditary cancer susceptibility. However, their sporadic counterparts, tumors that display a loss of BAP1 expression due to somatically arising mutations in the BAP1 gene, remain a poorly described entity. Case presentation: Here we present the case of a 49-year-old female who presented with an asymptomatic dome-shaped pink papule on the dorsal foot which was found on biopsy to be deficient in the BAP1 tumor suppressor. While the patient’s family history did not suggest the presence of a familial cancer syndrome, germline genetic testing was performed and was negative. The patient underwent surgical excision of this sporadically appearing “BAPoma” by Mohs surgery. Conclusions: Given the relatively banal clinical appearance of these dome-shaped neoplasms, sporadic BAPomas may often be overlooked by clinicians and dermatologists. In addition to providing a representative case, here we also provide a synopsis of the current understanding of these neoplasms, both in terms of the histopathological features, as well as the molecular mechanisms underlying BAP1 function and its ability to prevent tumorigenesis. Keywords: BAP1, Tumor suppression, Familial cancer syndrome Background More recently, sporadic somatic BAP1 mutations have Within the last decade, the BRCA1-Associated-Protein 1 been shown to occur in the setting of both mesothelioma (BAP1) has been increasingly appreciated for its tumor sup- and uveal melanoma [3]. -
