TRPS1 drives heterochromatic origin refiring and cancer genome evolution [copy number]

(Submitter supplied) The molecular etiology underlying TRPS1 loss-of-function in tricho-rhino-phalangeal syndrome (TRPS) remains to be understood. Intriguingly, TRPS1 is also bioinformatically postulated as a breast cancer driver. We report here that TRPS1 is prevalently amplified in breast cancer and promotes breast carcinogenesis. We showed that the tumorigenic potential of TRPS1 is derived from its nucleation of the replication machinery and its enforced replication of H3K9me3-marked heterochromatic regions. more...

Integrative Genomic Analysis of Medulloblastoma Identifies a Molecular Subgroup That Drives Poor Clinical Outcome [DNA copy number]

(Submitter supplied) Medulloblastomas are heterogeneous tumors that collectively represent the most common malignant brain tumor in children. To understand the molecular characteristics underlying their heterogeneity and to identify whether such characteristics represent risk factors for patients with this disease, we performed an integrated genomic analysis of a large series of primary tumors. Identified are six molecular subgroups of medulloblastoma, each with a unique combination of numerical and structural chromosomal aberrations that globally influence mRNA and miRNA expression. more...

An association study between somatic alterations and eQTL in immunity, DNA repair and inflammation pathways in esophageal squamous cell carcinoma (ESCC)

(Submitter supplied) Since ESCC is a complex and heterogeneous disease, it is increasingly important that analyses combine the evaluation of alterations in DNA, including somatic copy number alterations (SCNA), which distinguished from germ line copy number variants, allelic imbalance and LOH, and RNA, including those that occur in both mRNA and miRNA on the same specimen. Thus, in order to better understand their potential interactions in the development of cancers, in the present study, we studied alterations at DNA level as well as expression of mRNA and target miRNA in tumors and their matched normal tissues from 56 ESCC cases on a candidate tumor suppressor gene CSMD1 to characterize there alterations in this gene for import insights into the cellular detect that cause the complex disease, ESCC.

Key Super Enhancers Drive Tumor-Suppressing Transcription Feedback Programs in Mature B Cell Cancers (SNP array)

(Submitter supplied) Dynamic changes to the epigenome are essential regulators of B cell differentiation and, when perturbed, can lead to cancer. We compared three types of mature B cell lymphoma/leukemia (BCL) and normal lymphocytes to identify common and distinct epigenetic perturbations that promote oncogenesis. Purified malignant B cells from 52 patients (18 Follicular, 11 Diffuse Large B Cell, 23 Chronic Lymphocytic Lymphomas) and normal B cell subsets from 28 donor tonsils were subjected to chromatin immunoprecipitation and sequencing (ChIP-seq) for H3K4me1, H3K9/14ac, and H3K27ac; FAIRE-seq for open chromatin; RNA-seq; and genome copy number arrays. more...

Pharmacogenetics and Drug Discovery for Anthracycline-Induced Cardiotoxicity Enabled by Sinoatrial Node-like Cells Derived from Human Pluripotent Stem Cells [SNP array]

(Submitter supplied) The sinoatrial node (SAN) is the primary pacemaker of the heart. The human SAN is poorly understood due to limited primary tissue access and lack of robust in vitro derivation methods. We developed an efficient strategy, using a dual SHOX2:GFP; MYH6:mCherry knock-in reporter line, to generate and purify human pluripotent stem cell-derived SAN cells (hPSC-SAN), displaying molecular and electrophysiological characteristics of bona-fide nodal cells. more...

Copy-number profiling by SNP array of 4 acute myeloid leukemia (AML) cell lines

(Submitter supplied) DNMT inhibitors (DNMTi) are finally approved for AML/MDS, also based on their activity in patients with high-risk cytogenetics (often monosomal karyotype) such as -5/del(5q) or -7/del(7q), often - but not always - harboring TP53-mutations. Several studies provided evidence for aberrant hypermethylation/silencing on monoallelic gene loci, including tumor suppressor genes. We hypothesized that transcriptional repression on monosomal gene loci may be preferentially reversed by DNMTi. more...

SNP array of 121 AML patients at diagnosis

(Submitter supplied) Acute myeloid leukemia (AML) patients carrying complex karyotype or aneuploidies have a very poor prognosis, with a 5-year overall survival lower than 20%. We and others have shown that complex karyotype and aneuploid patients are characterized by high genomic instability, along with defects of DNA damage response genes and, occasionally, by chromothripsis. Chromothripsis frequently occurs in AML (6.6%) and influences patient prognosis and disease biology. more...

Novel Rare Copy Number Variants Associated with Tetralogy of Fallot in the Han Chinese Population

(Submitter supplied) Tetralogy of Fallot (TOF), the most frequent cyanotic congenital heart disease, occurs as a simplex trait of unknown etiology in the majority of cases. Studies of non-Asian populations suggest that approximately 10% of TOF cases carry a de novo rare copy number variant (CNV) thought to underlie the malformation. A genome-wide CNV analysis was performed in 303 TOF and 302 controls of Han Chinese as well as compared to 1,000 common Chinese database and revealed 166 rare CNVs identified in TOF patients with 119 CNVs further evaluated as potential “TOF-specific CNVs”; 98 were validated by qPCR, and 44 CNVs showed positive results on validation (positive rate 46.9%, 44/98). more...

The Brazilian Initiative on Precision Medicine (BIPMed)

(Submitter supplied) The development of precision medicine strategies requires prior knowledge of the genetic background of the target population. However, despite the availability of data from admixed Americans within large reference population databases, we cannot use these data as a surrogate for that of the Brazilian population. This lack of transferability is mainly due to differences between ancestry proportions of Brazilian and other admixed American populations. more...

Copy number variation analysis in Japanese children with Autsim Spectrum Disorder by Affymetrix Genome-Wide Human SNP Array 6.0.

(Submitter supplied) Autism spectrum disorder (ASD) is an innate neurodevelopmental disorder characterized by impairments in social communication/interaction, repetitive and restrictive behavior. Copy number variation (CNV) is a one of the structural variation of the genomic sequence, including large multiplications and deletions ranging from kb to Mb of DNA. These multiplication-deletion provide genomic diversity, while CNV affects the amount of gene products or transcriptional regulation, and result in strong association with biological process, metabolism and disease. more...

Genomic comparison of post-radiation versus sporadic sarcomas

(Submitter supplied) Post-radiation sarcomas are rare secondary cancers arising from radiation therapies. To date, few genetic specificities have been described for such malignancies and the oncogenesis of sarcomas with complex genetics (both sporadic and post-radiation) remains largely misunderstood. We performed genomic analyses on both sporadic and post-radiation sarcomas to study their copy-number alterations. This analysis is described in Lesluyes et al. more...

Genomic data from 48 Asian gastric patient-derived xenograft (PDX) models, 7 Asian gastric patient tumors and the 8 corresponding normal tissues

(Submitter supplied) There is a strong need to develop patient-derived xenograft (PDX) tumor models for studying new treatment options for gastric cancer (GC). With low engraftment success, few collections of GC PDX have been reported and molecular basis of the model establishment remain largely unknown. Here we established n=27 PDX models from n=100 GC tumors and compared their characteristics to GC patient tumors based on the recent work done by ACRG and TCGA, to evaluate the representativeness and relevance of the collection for drug testing. more...
