• The Effect of the Menstrual Cycle on DNA Expression in the Normal Human Breast Epithelium

  The Susan G. Komen for the Cure® Tissue Bank at the IU Simon Cancer Center [www.komentissuebank.iu.edu] (KTB) was established expressly for the prospective collection of normal, healthy breast tissue from volunteer donors. Blood is also obtained from donors at the time of donation and is processed for serum, plasma and peripheral blood leukocyte DNA. Specimens are annotated and data includes age, race, ethnicity, personal health history, family cancer history, medication usage at the time of donation, and breast cancer risk factors. Premenopausal donors to the KTB were identified by a query of the Bank's database. Hematoxylin and eosin stained sections of the formalin-fixed paraffin-embedded tissue of the identified donors were reviewed and tissue was graded on the basis of the abundance of epithelium within the section. Only tissue containing abundant epithelium was considered for this study. Based on dates, the specimens of nine women in the follicular phase of the menstrual cycle and five in the luteal phase were chosen. Six donors using hormonal contraception at the time of donation were also included. Whole blood obtained from 19 of the 20 donors at the time of tissue donation was available and it was processed for serum. Estradiol, estriol, luteinizing hormone and progesterone concentrations were determined by the Indiana University Health Pathology Laboratory using a Beckman Unicel DxI 800 Immunoassay System. The phase of the menstrual cycle was verified by serum progesterone concentration. The epithelium of these 20 specimens was microdissected from multiple 8 micron frozen tissue sections. Total RNA extracted from the tissue was subsequently depleted of rRNA via locked nucleic acid probes. This enabled profiling of both poly-A and non-poly-A RNA species. Barcoded cDNA libraries from the 20 normal breast epithelia were prepared and sequenced on an Applied Biosystems (AB) SOLiD3 or SOLiD 4 platform. RNA-seq reads for each sample were then mapped to the human genome (hg19) using the LifeScope software version 2.5.1 (Life Technologies, Foster City, CA) and BAM (Binary Alignment/Map) files generated. Read counts for each gene were derived from the output BAM files using the RefSeq database (UCSC Genome Brower) as the gene model.

• Accelerating Medicines Partnership-Systemic Lupus Erythematosus (AMP-RA/SLE)

  This project is analyzing tissue and blood samples from people with rheumatoid arthritis (RA) and lupus to pinpoint genes, proteins, chemical pathways, and networks involved at a single cell level. This type of modular, molecular analysis will allow comparisons across the diseases and will provide insights into key aspects of the disease process. The project will identify differences between those RA patients who respond to therapies and those who do not, as well as provide a better systems level understanding of disease mechanisms in both RA and lupus. This knowledge is essential for the development of targeted therapies and for the application of existing and future therapies to appropriate patient populations.

• Genome wide association study for early onset coronary disease and related phenotypes (ADVANCE)

  ADVANCE (Atherosclerotic Disease, VAscular functioN, and genetiC Epidemiology) is a large epidemiological study of genetic and non-genetic determinants of coronary artery disease (CAD) that started in 2000 as a collaborative effort between researchers at Stanford University and Kaiser Permanente of Northern California. The overarching goal of the study is to improve our ability to prevent, diagnose and treat CAD. The initial study included recruitment of over 3600 subjects (including 1873 subjects with incident clinically significant coronary disease and 1745 control subjects) from multiple race/ethnic backgrounds. A subset of ~ 500 subjects with very early onset coronary disease (men < 45 and women < 55) and ~ 500 similar aged controls were genotyped using the Illumina 550K platform as part of an NIH funded effort within the STAMPEED consortium.

• Targeted Sequencing of Primary ER-positive Breast Tumors Treated with 5 Years of Tamoxifen

  Targeted massively parallel sequencing analysis was conducted on DNA extracted from archived 22-28 year old, formalin-fixed primary breast tumors from 625 patents from British Columbia treated with five years of adjuvant tamoxifen monotherapy and followed for over 10 years. Genes were selected for targeted sequencing by review of existing large-scale breast cancer sequencing studies and breast cancer literature. In total, 83 genes were identified and 3,029 probes were designed to tile across all known exons. Illumina sequencing libraries were constructed, indexed, pooled, and enriched for target sequences by hybrid-capture followed by sequencing of paired-end 100bp reads. All samples met minimum quality controls of 80% targeted space covered at 20X or greater. On average, each sample had 336M aligned bases and a mean coverage of 135.8X.

• Defining and Overcoming Intrinsic T Cell Dysfunction to Enable Pediatric Immunotherapy

  T-cells from 71 children and young adults with B-cell malignancies on trial to receive anti-CD19 CAR T-cell therapy were analyzed. These T-cells represent the pre-manufacture T-cells that were subsequently used for CAR T manufacture. Bulk RNA-Seq was performed on sorted T-cell subsets for all patients, in addition to CITE-Seq and single-cell ATAC-Seq on a subset of 6 patients. The primary clinical outcome was duration of B-cell aplasia, a surrogate measure of functional CAR T-cell persistence. From these data, molecular signatures associated with long and short-term CAR T-cell persistence were identified. This data submission includes bulk RNA-Seq, CITE-Seq, and single-cell ATAC-Seq data from this study.

• The Longevity Genes Project

  Aging is a complex, universal condition leading to the functional decline of all cells and organisms, and to major national and global public health problems. Although aging is the major risk factor for developing most adult-onset diseases, systematic investigations into the fundamental physiology, biology and genetics of aging are only just beginning. In the Longevity Genes Project at Albert Einstein College of Medicine, Dr. Nir Barzilai and his team conducted genetic research on more than 500 healthy elderly people between the ages of 95 and 112, and on their children. The identification of longevity genes by Einstein researchers could lead to new drug therapies that might help people live longer, healthier lives and avoid or significantly delay age-related diseases such as Alzheimer's disease, type 2 diabetes and cardiovascular disease.

• Health Professionals Follow-Up Study

  Health Professionals Follow-up Study (HPFS) is a prospective cohort study of men designed to evaluate hypotheses about men’s health related to diet and lifestyle to the incidence of serious illnesses, such as cancer, heart disease, and other vascular diseases. It consisted of 51,529 U.S. male health professionals who were 40-75 years old at baseline in 1986 and completed a mailed six-page baseline questionnaire. Information on age, height and weight, ancestry, medications, disease history, physical activity, lifestyle factors, and diet were gathered, with follow-up questionnaires sent biennially to update information and record health outcomes with every four years to update their diet. This datafile includes responses to the 2016 questionnaire, which is available at: https://cdn1.sph.harvard.edu/wp-content/uploads/sites/2471/2017/09/16L.pdf

• The Finland-United States Investigation of NIDDM Genetics (FUSION) Study

  The Finland-United States Investigation of NIDDM Genetics (FUSION) study is a long-term effort to identify genetic variants that predispose to type 2 diabetes (T2D) or that impact the variability of T2D-related quantitative traits. The initial effort involved linkage analysis of affected-sibling-pair (ASP) families based on over 5,000 individuals living in Finland, and association fine mapping based on these family members and additional T2D cases and controls. Recently we completed a genome-wide association scan on 1161 T2D cases and 1174 normal glucose tolerant (NGT) controls. Individual-level data is available here for the 919 T2D cases and 787 NGT controls who reconsented to the use of their data or are deceased. Version 3 adds individual-level data for additional phenotypic variables.

• Sensitivity to the Subjective Effects of Amphetamine

  The goal of this study was to identify SNPs associated with subjective, physiological, and behavioral responses to d-amphetamine. The study was double-blind and placebo-controlled. 381 healthy volunteers aged 18-35 years old received oral doses of d-amphetamine (10 and 20 mg) and placebo over the course of three different phenotyping sessions. A subset of subjects received a fourth dose of d-amphetamine (5 mg). Measures of subjective, cardiovascular and behavioral responses were obtained at regular intervals (pre-drug administration and 30, 60, 90, 150, and 180 minutes post-drug administration). The subjective measures included in the study were the Profile of Mood States (POMS), Drug Effects Questionnaire (DEQ) and Addiction Research Center Inventory (ARCI). Tasks included were the Digit Symbol Substitution (DSST) and Stop Task.
