• Papua New Guinean Lowlanders Dataset

  High-coverage whole genome sequences were collected to study patterns of genomic variation across the southern lowland of Papua New Guinea. This region has experienced an extremely complex demographic history, including repeated bouts of admixture with archaic and modern human groups. This dataset reports whole genome sequences for 41 individuals from this region. Particular attention has been paid in the original study to genomic signals that are informative for population history, including admixture with archaic hominins and the role of modern human admixture during the late Pleistocene and Holocene.

• High Resolution Analysis of Spatial Interactions of Hundreds of Promoters in HeLa Cells

  In this study we developed a new hybridisation-based promoter Capture-C protocol that makes use of biotinylated dsDNA probes and allows high-resolution promoter interactome description. Experiments aimed to describe spatial interactions of set of 861 promoters were performed in HeLa cells. We have found that enrichment efficiency and quality of final libraries in our study is on a par with established promoter Capture-C protocols. Meanwhile, our version of the probe preparation protocol is reasonably simple and makes Capture-C experiments more affordable and flexible.

• Whole Exome Sequencing of Human Gastro-esophageal Cancer PDXs

  The current study investigates biomarkers of response to anti-EGFR therapies in gastro-esophageal cancer. Whole exome sequencing was performed on 26 tumors to explore potential factors influencing treatment outcomes. As part of the analysis, somatic mutations in EGFR, ERBB2, and key downstream signaling genes (KRAS and PIK3CA) were examined to exclude the presence of known mutations conferring sensitivity/resistance. The study aims to contribute to the identification of patients who may benefit from lower-toxicity regimens, improving treatment personalization and minimizing adverse effects.

• The Oral Mycobiome and Risk of Pancreatic Cancer

  The purpose of our study was to assess the influence of oral microbiota on the development of pancreatic cancer. Our preliminary case-control studies showed that oral carriage of a periodontal pathogen is related to increased risk for pancreatic cancer. We hypothesize that the oral bacteria and fungi are associated with risk of pancreatic cancer. We conducted a prospective study nested in two large well-established U.S. cohorts to determine whether the oral bacterial and fungal microbiome is associated with subsequent risk of pancreatic cancer.

• Whole-genome sequencing analysis for understanding of the stepwise progression of lung adenocarcinoma

  In this study, we performed long and short read whole-genome sequencing analysis of lung adenocarcinoma from early to advanced stages to identify molecular events associated with the stepwise progression of lung adenocarcinoma. We particularly focused on very early stage of lung adenocarcinoma, such as adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA). In addition to the whole-genome sequencing analysis, we conducted transcriptome and epigenome analysis, multiplex fluorescence immunostaining. This study would enable us to understand important molecular events of pathogenesis in detail during lung adenocarcinoma progression.

• Contribution of specific cell types to the development of Barrett’s esophagus and carcinoma via germline genetic risk

  This study was designed to elucidate how individual cell types in Barrett’s esophagus (BE) and esophageal adenocarcinoma (EAC) contribute to disease development via germline genetic risk. We performed single cell RNA-sequencing (scRNA-seq) of BE, EAC and paired normal esophagus and gastric fundus tissue samples. After analyzing individual cell types, we integrated the scRNA-seq data and data of a genome-wide association study (GWAS) on BE/EAC to determine cell type-specific genetic risk. Raw data from the RNA-sequencing is provided here.

• WES of Mino-VEN-R Mantle Cell Lymphoma Cells

  This project investigates the genetic basis of therapy resistance in mantle cell lymphoma (MCL) using whole exome sequencing (WES) of the Mino_VEN_R cell line, a model of resistance to pirtobrutinib, a non-covalent BTK inhibitor. Our study suggested that drug-tolerant persister (DTP) cells evade therapy through metabolic and phenotypic reprogramming. By analyzing the exome profile of resistant cells, this study aims to identify mutations associated with treatment escape and cellular plasticity. The findings will contribute to a better understanding of resistance mechanisms and support the development of more effective therapeutic strategies.

• Celiac disease meta-analysis

  Celiac disease (CeD) is a common immune-mediated disease of the small intestine that is triggered by exposure to dietary gluten. While the HLA locus plays a major role in disease susceptibility, 39 non-HLA loci were also identified in a study of 24,269 individuals. We now build on this earlier study by adding 4,125 additional Caucasian samples including an Argentinian cohort genotyped on the Immunochip. In doing so, we not only confirm the previous associations, we also identify two novel independent genome-wide significant associations.

• National Cancer Institute (NCI) Head and Neck Cancer Study

  Head and neck cancers have well-documented associations with tobacco and alcohol exposure, but the disease develops in only a small fraction of users, which implies an important role for genetic susceptibility. Therefore, head and neck cancers are an excellent model for studying genetic susceptibility to environmental carcinogens. The primary goal of this study is to perform a comprehensive two-stage, high-density, genome-wide single-nucleotide polymorphism (SNP) analysis of head and neck cancer cases and corresponding frequency matched controls to identify novel genetic risk factors for head and neck cancer. In the study, we genotyped 2242 head and neck cancer cases and 1198 controls using Illumina HumanOmniExpress-12v1 BeadChip.

• Immune Profiles Study

  This study assesses glioma patient blood methylation longitudinally beginning pre-surgery through other clinically important timepoints. Progression and survival are studied in relation to methylation derived immunologic profiles and other characteristics. For this study, patients scheduled for surgery at University of California San Francisco (UCSF) for a possible newly diagnosed glioma (grades 2-4) or recurrent grade 2/3 glioma were consented and enrolled. Patients had blood collected pre-surgery and, if the pathology results confirm a glioma, every few weeks or months during their treatment (up to 30 total timepoints). Blood immunomethylomic profiles were measured at these timepoints to assess associations with glioma patient outcomes, clinical measures, other known prognostic markers, and imaging characteristics.

• Identification of 22 Novel Loci Associated with Susceptibility to Testicular Germ Cell Tumors

  Testicular germ cell tumors (TGCT) are the most common cancers in young men of European ancestry aged 20 to 39 years. The Testicular Cancer Consortium (TECAC) has brought together the largest genome-wise association study (GWAS) study of TGCT to date. We conducted a GWAS of 5,602 cases and 5,006 controls aggregated from 12 locations in the US and Europe. Logistic regression models adjusted for study center and genomic ancestry. Genotypes were imputed against the Human Haplotype Reference Consortium. Meta-analysis was performed to combine GWAS results with summary statistics from five previously published TGCT studies, UK Biobank, deCODE Genetics, and an independent set of cases and controls, for a total of 10,156 cases and 179,683 controls. 22 novel and 45 previously reported loci associated with TGCT surpassed genome-wide significance (p < 5e-08).

• Characterization of X Chromosome Inactivation Using Integrated Analysis of Whole-Exome and mRNA Sequencing

  This study of DNA and RNA sequencing of 5 parent-offspring trios is a single center study. The goal of this study is to characterize X chromosome inactivation (XCI) ratio in females using phased genomic variations obtained through whole genome or exome sequencing in trios, followed by allele-specific expression analysis of the phased, heterozygous alleles in the mRNA of the female offspring, and to apply this method to clinical diagnosis. The distribution of allele ratios across X obtained from mRNA sequencing allows for the estimation of X inactivation status of inherited X chromosomes, and the parameters of each parental allele distributions in the offspring's mRNA data can be used as determinants for XCI ratio. This approach was used to evaluate the contribution of skewed XCI ratio to phenotypic heterogeneity in an undiagnosed, mild neurological condition.

• Whole Genome Sequencing of Harvard University Embryonic Stem Cell Lines 63 and 64

  In this study we used next generation deep sequencing technologies to analyze the genomes of Harvard University Stem Cell lines 63 and 64. We performed 101-bp paired-end whole genome sequencing of the two cell lines using Illumina HiSeq platforms. The sequence reads obtained were analyzed for copy number and used for replication timing analysis. Our data suggests that read depth profiles can be used to map replication timing in Embryonic Stem Cells (ESCs). Further we observe that replication profiles are highly correlated across ESCs but distinct from those of other cell types such as Lymphoblastoid Cell Lines (LCLs). These results demonstrated that read depth data from whole genome sequencing can be used to study variation in replication timing within the human population and across different cell types. Whole genome sequences from HUES63 and HUES64 used for this study are being submitted.

• Circulating Tumor DNA in Intermediate Risk Rhabdomyosarcoma

  In this study, we evaluated circulating tumor DNA (ctDNA) as a biomarker in the serum of 124 patients with newly diagnosed intermediate risk rhabdomyosarcoma (IR RMS) from the Children's Oncology Group (COG) biorepository. In addition to pre-treatment serum, we also analyzed matched tumor tissue and germline in a subset of patients. We profiled samples using ultra-low passage whole genome sequencing (ULP-WGS) and a new custom hybrid-capture sequencing assay, Rhabdo-Seq, to detect copy number alterations, rearrangements, and single nucleotide variants. We found that patients with detectable ctDNA at diagnosis had significantly worse outcomes than those without detectable levels of ctDNA. Our study demonstrates that baseline ctDNA detection is feasible and prognostic in IR RMS. The ULP-WGS and targeted next-generation sequencing (Rhabdo-Seq and TranSS-Seq) data are available in this study.
