• Radiation-Related Genomic Profile of Papillary Thyroid Cancer after the Chernobyl Accident

  The April 26, 1986 accident at the Chernobyl nuclear power plant in northern Ukraine resulted in the release of radioactive contaminants, which were deposited in the surrounding areas in Ukraine, Belarus, and Russia. The main radiation-related health effect resulting from these exposures is the increased occurrence of thyroid cancer among individuals who were children at the time of the accident or born shortly thereafter. The purpose of this study was to conduct a comprehensive genomic landscape analysis of papillary thyroid tumors arising in individuals who were exposed as children to radioactive iodine (I-131) from the Chernobyl nuclear power plant accident.

• COVID-19-Induced Immune Alterations in Infants

  Although previous studies have described some overlap between COVID-19-induced immune alterations in adults and children, no systematic immune profiling studies have been reported in infants. We applied a multidimensional approach to decipher the immune responses to SARS-CoV-2 infected infants (n=26; 10 mild, 11 moderate and 5 severe) and healthy matched controls (n=14). Single-cell RNA-seq profiling (scRNA-seq) of PBMCs revealed alterations in cell composition upon infection, with most cell types demonstrating an interferon-stimulated gene (ISGhi) state. Our findings shed insight into the immune responses to SARS-CoV-2 in the first year of life.

• Evolution of Structural Rearrangements in Prostate Cancer Intracranial Metastases

  Intracranial metastases in prostate cancer are uncommon but clinically aggressive. We sought to characterize prostate cancer intracranial metastases in order to improve our understanding of their pathogenesis and to promote the search for new treatment strategies. We evaluated the clinical and molecular characteristics of 36 patients with metastatic prostate cancer to either the dura or brain parenchyma. We performed whole genome sequencing (WGS) on samples from 21 patients. The WGS samples include 10 intracranial prostate cancer metastases, as well as WGS of primary prostate tumors from men who later developed metastatic disease (n=6) and non-brain prostate cancer metastases (n=26).

• Pre-existing immunity drives the response to neoadjuvant chemotherapy in esophageal adenocarcinoma

  Esophageal adenocarcinoma (EAC) is a highly aggressive tumor. Patients with locally advanced disease undergo neoadjuvant chemotherapy (nCT) before surgery, however fewer than 30% of treated patients achieve a pathological complete response associated with increased 5-year overall survival. We set out to elucidate the mechanisms the response to nCT by multi-dimensional profiling of pre-treatment tumor biopsies and blood samples from EAC patients. In particular we performed whole exome sequencing (WES) and RNAseq on n=26 baseline EAC tumor; two additional EAC samples underwent only WES. WES on matched peripheral blood mononuclear cells (PBMCs) were used as germline control.

• Cell-free DNA TAPS for early cancer detection

  Multimodal, genome-wide characterization of epigenetic and genetic information in circulating cell-free DNA (cfDNA) could enable more sensitive early cancer detection. However, due to technological challenges associated with DNA methylation sequencing in low input cfDNA samples, most studies have been limited by DNA damage caused by bisulfite sequencing, or the qualitative nature of enrichment-based sequencing. Recently, we developed TET-assisted Pyridine Borane Sequencing (TAPS), which is a mild, bisulfite-free method for base-resolution direct DNA methylation sequencing. Here we optimized TAPS for cfDNA (cfTAPS) to provide high-quality and high-depth whole-genome cell-free methylomes. We applied cfTAPS to 85 cfDNA samples from patients with hepatocellular carcinoma (HCC) or pancreatic ductal adenocarcinoma (PDAC) and non-cancer controls. From just 10 ng cfDNA (1-3 mL of plasma), we generated the most comprehensive cfDNA methylome to date. We demonstrated that cfTAPS provides multimodal information about cfDNA characteristics, including DNA methylation, tissue of origin, and DNA fragmentation. Integrated analysis of these epigenetic and genetic features enables accurate identification of early HCC and PDAC.

• Cell-Free, Methylated DNA in Blood Samples Reveals Tissue-Specific, Cellular Damage from Radiation Treatment

  Radiation therapy is an effective cancer treatment, although damage to surrounding healthy tissues can also occur. Cell-type specific DNA methylation patterns can be used to decode the cellular origins of cell-free DNA fragments, allowing for minimally-invasive monitoring of tissue damage. To evaluate whether changes in cell-free DNA methylation can indicate damages to tissues in patients treated with radiation, we collected serum samples from 15 breast cancer patients at three timepoints during their standard-of-care radiation therapy after surgery. A baseline sample was taken for each patient before onset of radiation therapy and a second End-Of-Treatment (EOT) sample was taken 30 minutes after the last treatment fraction. Finally, a recovery sample was taken one month after completion of radiation therapy. From serum samples, cell-free DNA was isolated and bisulfite capture-sequencing DNA methylation data were generated. Bisulfite capture-sequencing DNA methylation data were also generated from buffy coat and tissue-specific endothelial gDNA samples as well as from serum/plasma samples of healthy controls. The analysis of serum samples from breast cancer patients undergoing radiation treatment revealed distinct tissue-specific epithelial and endothelial responses to radiation across multiple organs. In conclusion, as a proof of concept we show that cell-type specific methylation signatures can be applied to detect cellular injury from radiation treatment using minimally invasive cell-free DNA in blood samples.

• Sleep Abnormalities in Rare Genetic Disorders: Angelman Syndrome, Rett Syndrome, and Prader-Willi Syndrome

  This research study will investigate sleep behavior in the rare neurological disorders Angelman Syndrome (AS), Rett Syndrome (RTT), Prader-Willi Syndrome (PWS) and Early-onset Morbid Obesity (EMO). Sleep is very important to proper health and plays a critical role in learning, memory, brain development and brain function. Sleep disturbances can have negative effects on health and the quality of life of children and their families. Sleep disorders are common in individuals with AS, RTT, PWS and EMO. As a result, individuals with AS, RTT, PWS and EMO are at risk for sleep-related health problems that can worsen existing daytime behaviors and lead to additional problems with learning and memory. The principal objectives of the study are to: Characterize sleep behavior in individuals with Angelman Syndrome, Rett Syndrome, Prader-Willi Syndrome and Early-onset Morbid Obesity. Compare sleep behavior in these individuals with sleep behavior in normal controls Assess the natural history of sleep behavior in individuals with Angelman Syndrome, Rett Syndrome, Prader-Willi Syndrome and Early-onset Morbid Obesity About this Study This is a questionnaire study that will evaluate the sleep behavior of individuals with AS, RTT or PWS (participants), or unaffected siblings of individuals with AS, RTT or PWS (controls). Those participating in the study will already be registered with the Rare Disease Clinical Research Network (RDCRN) and have a confirmed diagnosis of AS, RTT or PWS or be an unaffected sibling. We will look at the medical records on file with the RDCRN to confirm diagnosis of AS, RTT or PWS. Study participants will participate in the study at their regularly scheduled RDCRN clinic visits. Participants will be asked to complete questionnaires at the study visits that will document their sleep behaviors. The questionnaires are not difficult and participants should be able to complete them in approximately 15-30 minutes. Parents and legal guardians are allowed to assist participants or answer on their behalf. Questionnaires will be administered at the initial study visit and at a 12 month follow-up visit to document any changes in sleep behavior. We hope to enroll approximately 1400 individuals with either AS, RTT or PWS or their unaffected siblings.

• Potential Modulatory Role of Osteoprotegerin in Bone Metabolism of Patients with 21-Hydroxylase Deficiency

  21-hydroxylase deficiency (21-OHD) is an inherited disorder that results from a mutation on the CYP21A2 gene. It affects the adrenal glands and is the most common cause of congenital adrenal hyperplasia (CAH). 21-OHD CAH causes the body to produce an insufficient amount of cortisol and an excess of androgen, the type of hormone that produces male characteristics. The primary treatment for 21-OHD CAH, glucocorticoid replacement therapy, has been shown to cause bone loss. However, the elevated hormone levels caused by 21-OHD CAH may increase production of the protein osteoprotegerin (OPG), which in turn may protect against bone loss. This study will compare bone density and OPG levels in women who have 21-OHD CAH and have undergone a lifetime of glucocorticoid replacement therapy to that in women who have neither of these criteria. In doing so, the study will aim to determine the relationship between OPG and bone loss. Because of the excess of androgen caused by 21-OHD CAH, women with CAH may exhibit some male-like characteristics. Glucocorticoids are a member of a class of drugs called corticosteroids, which are used in hormone replacement therapy. In order to counteract the effects of 21-OHD CAH, women with the disease are given hormone replacement therapy with glucocorticoids beginning at infancy. Glucocorticoids are known to cause bone loss. Despite many years of treatment with glucocorticoids, however, young women with 21-OHD CAH seem to be protected against bone loss. Researchers believe that the increased androgen levels in these women lead to increased estrogen levels, which in turn increase OPG production. The increase in OPG levels may protect women against bone loss. This study will evaluate bone density and OPG levels in women with and without 21-OHD CAH to determine the relationship between OPG and bone loss. Participants in this observational study will attend only one study visit. At this visit, they will undergo a blood draw; a scan of their lower spine, hip, and forearm; height and weight measurements; and a body fat analysis test. This last test will entail a weak and painless electrical signal being sent from foot to foot. Participants will not attend any follow-up visits for this study.

• Structure and Diversity of Urinary Cell-Free DNA Informative of Host-Pathogen Interactions in Human Urinary Tract Infection

  The risk of acquiring urinary tract infection (UTI) is very high for patients who have received kidney transplants; nearly half will develop bacteriuria and an eighth viruria via BK polyomavirus in the first three years following transplantation. Current methodology for diagnosing viral and bacterial infections, while well practiced, is often limited in scope. The advent of next generation sequencing of cell-free DNA has shown promise in its ability to capture multiple perspectives of human health from discovering the origin of cell-free DNA in plasma; such a diagnostic has not been readily applied to urinary cell-free DNA. In this study, we selected 141 urine samples from a cohort of kidney transplant patients, which were collected and stored at Weill Cornell Medical College - New York Presbyterian Hospital. Of these samples, 43 samples were determined to be culture positive (> 10,000 CFU) for one or more bacterial species, including E. coli, Enterococcus, Klebsiella, Haemophilus, and Raoultella. A separate 23 samples were confirmed for BK virus nephropathy, with presence of BK polyomavirus confirmed via qPCR. We also included 29 samples from 14 patients who did not develop UTIs in the first three months following transplantation, and 11 samples that were negative for BK virus nephropathy. For a full description of samples, please see the Supplementary Data 1 in https://pubmed.ncbi.nlm.nih.gov/29925834/. From these urine samples, we aimed to capture and sequence urinary cell-free DNA using a single-stranded library preparation. In addition, we performed whole-genome bisulfite sequencing to 170 plasma samples collected from 27 hematopoietic cell transplant patients who developed graft-versus host disease and BK polyomavirus infection. We also performed Sample-Intrinsic microbial DNA Found by Tagging and sequencing (SIFT-seq) on 196 cell-free DNA (cfDNA) samples (154 plasma and 42 urine) collected from five groups of subjects. For a full description of samples, please see publications in PMID: 35864089 and PMID: 35058359.
