Ashbrook2 1Department of Biotechnology, Chaitanya Bharathi Institute of Technology, Hyderabad 500075, India 2Department of Genetics, Genomics and Informatics, University of Tennessee Health Science Center, Memphis, TN 38163, USA Abstract Understanding gene-by-environment interactions is important across biology, particularly behaviour. Families of isogenic strains are excellently placed, as the same genome can be tested in multiple environments. The BXD’s recent expansion to 140 strains makes them the largest family of murine isogenic genomes, and therefore give great power to detect QTL. Indefinite reproducible genometypes can be leveraged; old data can be reanalysed with emerging tools to produce novel biological insights. To highlight the importance of reanalyses, we obtained drug- and behavioural-phenotypes from Philip et al. 2010, and reanalysed their data with new genotypes from sequencing, and new models (GEMMA and R/qtl2). We discover QTL on chromosomes 3, 5, 9, 11, and 14, not found in the original study. We narrowed down the candidate genes based on their ability to alter gene expression and/or protein function, using cis-eQTL analysis, and variants predicted to be deleterious. Co-expression analysis (‘gene friends’) and human PheWAS were used to further narrow candidates. -

Read Full License Page 1/22 Abstract Background: PTPRD plays an indispensable role in the occurrence of multiple tumors. However, pan- cancer analysis is unavailable. The purpose of this research was to investigate the relationship between PTPRD and immunity and describe its prognostic landscape across various tumors. Methods: We explored expression prole, survival analysis, and genomic alterations of PTPRD based on the TIMER, GEPIA, UALCAN, PrognoScan, and cBioPortal database. The frequency of PTPRD mutation and its correlation with response to immunotherapy were evaluated using the cBioPortal database. The relationship between PTPRD and immune-cell inltration was analyzed by the TIMER and TISIDB databases. A protein interaction network was constructed by the STRING database. GO and KEGG enrichment analysis was executed by the Metascape database. Results: A signicant correlation between PTPRD expression and prognosis was found in various cancers. Aberrant PRPRD expression was closely related to immune inltration. Importantly, the patients who harbored PTPRD mutation and received immune checkpoint inhibitors had worse overall survival, especially in non-small cell lung cancer and melanoma, and had a higher TMB score. -
Genetic Mutations Underlying Phenotypic Plasticity in Basosquamous Carcinoma Audris Chiang1,2,7, Caroline Z
See related commentary on pg 2258 ORIGINAL ARTICLE Genetic Mutations Underlying Phenotypic Plasticity in Basosquamous Carcinoma Audris Chiang1,2,7, Caroline Z. Tan1,7, Franc¸ois Kuonen1, Luqman M. Hodgkinson1, Felicia Chiang3, Raymond J. Cho4, Andrew P. South5,JeanY.Tang1, Anne Lynn S. Chang1, Kerri E. Rieger1,6, Anthony E. Oro1 and Kavita Y. Sarin1 Basosquamous carcinoma (BSC) is an aggressive skin neoplasm with the features of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). While genetic drivers of BCC and SCC development have been extensively characterized, BSC has not been well studied, and it remains unclear whether these tumors orig- inally derive from BCC or SCC. In addition, it is unknown which molecular pathways mediate the reprog- ramming of tumor keratinocytes toward basaloid or squamatized phenotypes. We sought to characterize the genomic alterations underlying sporadic BSC to elucidate the derivation of these mixed tumors. We identifed frequent Hedgehog (Hh) pathway mutations in BSCs, implicating Hh deregulation as the primary driving event in BSC. Principal component analysis of BCC and SCC driver genes further demonstrate the genetic similarity between BCC and BSC. In addition, 45% of the BSCs harbor recurrent mutations in the SWI/SNF complex gene, ARID1A, and evolutionary analysis revealed that ARID1A mutations occur after PTCH1 but before SCC driver mutations, indicating that ARID1A mutations may bestow plasticity enabling squamatization. Finally, we demonstrate mitogen-activated protein kinase pathway activation and the loss of Hh signaling associated with the squamatization of BSCs. Overall, these results support the genetic derivation of BSCs from BCCs and highlight potential factors involved in modulating tumor reprogramming between basaloid and squamatized phenotypes. -
RSU1) in Cancer Cell Metastasis: a Tale of a Tumor Suppressor

It has a strong genetic background, as mutations in oncogenes or tumor suppressor genes contribute to the initiation of cancer development. Integrin signaling as well as the signaling pathway of Ras oncogene, have been long implicated both in carcinogenesis and disease progression. Moreover, they have been involved in the promotion of metastasis, which accounts for the majority of cancer-related deaths. Ras Suppressor-1 (RSU1) was identified as a suppressor of Ras-induced transformation and was shown to localize to cell-extracellular matrix adhesions. Recent findings indicate that its expression is elevated in various cancer types, while its role in regulating metastasis-related cellular processes remains largely unknown. Interestingly, there is no in vivo work in the field to date, and thus, all relevant knowledge stems from in vitro studies. In this review, we summarize recent studies using breast, liver and brain cancer cell lines and highlight the role of RSU1 in regulating cancer cell invasion. -
From Bipotent Neuromesodermal Progenitors to Neural-Mesodermal Interactions During Embryonic Development
International Journal of Molecular Sciences Review From Bipotent Neuromesodermal Progenitors to Neural-Mesodermal Interactions during Embryonic Development Nitza Kahane and Chaya Kalcheim * Department of Medical Neurobiology, Institute of Medical Research Israel-Canada (IMRIC) and the Edmond and Lily Safra Center for Brain Sciences (ELSC), Hebrew University of Jerusalem-Hadassah Medical School, P.O. Box 12272, Jerusalem 9112102, Israel; [email protected] * Correspondence: [email protected] Abstract: To ensure the formation of a properly patterned embryo, multiple processes must operate harmoniously at sequential phases of development. This is implemented by mutual interactions between cells and tissues that together regulate the segregation and specification of cells, their growth and morphogenesis. The formation of the spinal cord and paraxial mesoderm derivatives exquisitely illustrate these processes. Following early gastrulation, while the vertebrate body elongates, a pop- ulation of bipotent neuromesodermal progenitors resident in the posterior region of the embryo generate both neural and mesodermal lineages. At later stages, the somitic mesoderm regulates aspects of neural patterning and differentiation of both central and peripheral neural progenitors. Reciprocally, neural precursors influence the paraxial mesoderm to regulate somite-derived myogen- esis and additional processes by distinct mechanisms. Central to this crosstalk is the activity of the axial notochord, which, via sonic hedgehog signaling, plays pivotal roles in neural, skeletal muscle and cartilage ontogeny. Here, we discuss the cellular and molecular basis underlying this complex Citation: Kahane, N.; Kalcheim, C. developmental plan, with a focus on the logic of sonic hedgehog activities in the coordination of the From Bipotent Neuromesodermal Progenitors to Neural-Mesodermal neural-mesodermal axis. -

BCC displays a different behavior compared with other neoplasms, has a slow evolution, and metastasizes very rarely, but sometimes it causes an important local destruction. Chronic ultraviolet exposure along with genetic factors are the most important risk factors involved in BCC development. Mutations in the PTCH1 gene are associated with Gorlin syndrome, an autosomal dominant disorder characterized by the occurrence of multiple BCCs, but are also the most frequent mutations observed in sporadic BCCs. -
Loss of the PTCH1 Tumor Suppressor Defines a New
Banerjee et al. J Transl Med (2019) 17:246 https://doi.org/10.1186/s12967-019-1995-z Journal of Translational Medicine RESEARCH Open Access Loss of the PTCH1 tumor suppressor defnes a new subset of plexiform fbromyxoma Sudeep Banerjee1,2, Christopher L. Corless3, Markku M. Miettinen4, Sangkyu Noh1, Rowan Ustoy1, Jessica L. Davis3, Chih‑Min Tang1, Mayra Yebra1, Adam M. Burgoyne5 and Jason K. Sicklick1* Abstract Background: Plexiform fbromyxoma (PF) is a rare gastric tumor often confused with gastrointestinal stromal tumor. These so‑called “benign” tumors often present with upper GI bleeding and gastric outlet obstruction. It was recently demonstrated that approximately one‑third of PF have activation of the GLI1 oncogene, a transcription factor in the hedgehog (Hh) pathway, via a MALAT1‑GLI1 fusion protein or GLI1 up‑regulation. Despite this discovery, the biology of most PFs remains unknown. Methods: Next generation sequencing (NGS) was performed on formalin‑fxed parafn‑embedded (FFPE) samples of PF specimens collected from three institutions (UCSD, NCI and OHSU). Fresh frozen tissue from one tumor was utilized for in vitro assays, including quantitative RT‑PCR and cell viability assays following drug treatment. Results: Eight patients with PF were identifed and 5 patients’ tumors were analyzed by NGS. An index case had a mono‑allelic PTCH1 deletion of exons 15–24 and a second case, identifed in a validation cohort, also had a PTCH1 gene loss associated with a suspected long‑range chromosome 9 deletion. Building on the role of Hh signaling in PF, PTCH1, a tumor suppressor protein, functions upstream of GLI1. Loss of PTCH1 induces GLI1 activation and down‑ stream gene transcription. -

Endothelial cell dysfunction is a starting point for pathogenesis of vascular complications in diabetes. We previously showed the polyol erythritol to be a hydroxyl radical scavenger preventing endothelial cell dysfunction onset in diabetic rats. To unravel mechanisms, other than scavenging of radicals, by which erythritol mediates this protective effect, we evaluated effects of erythritol in endothelial cells exposed to normal (7 mM) and high glucose (30 mM) or diabetic stressors (e.g. SIN-1) using targeted and transcriptomic approaches. This study demonstrates that erythritol (i.e. under non-diabetic conditions) has minimal effects on endothelial cells. However, under hyperglycemic conditions erythritol protected endothelial cells against cell death induced by diabetic stressors (i.e. high glucose and peroxynitrite). Also a number of harmful effects caused by high glucose, e.g. increased nitric oxide release, are reversed. Additionally, total transcriptome analysis indicated that biological processes which are differentially regulated due to high glucose are corrected by erythritol. We conclude that erythritol protects endothelial cells during high glucose conditions via effects on multiple targets. -
