A Multidisciplinary Study Links Androgen Signaling with Severe COVID-19 Symptoms in Men

This webinar will discuss a study that identified a link between male sex hormones and COVID-19 disease severity in men and also pointed toward possible therapeutic candidates for the disease.

Dr. Hani Goodarzi of the University of California, San Francisco, will share details of the work, which was based on the premise that SARS-CoV-2 infection occurs through binding of the viral spike protein to angiotensin converting enzyme 2 (ACE2) on the host cell membrane.

Dr. Goodarzi and colleagues used a high-throughput drug screening strategy to identify therapeutic candidates that reduce ACE2 levels in cardiac cells derived from human embryonic stem cells (hESCs). Analysis of validated hit compounds pointed to the central role of androgen signaling in ACE2 expression.

Treatment with antiandrogenic drugs, as well as in silico-derived compounds predicted to target this pathway, reduced ACE2 expression and protected hESC-derived lung organoids against SARS-CoV-2 infection.

Finally, clinical data on COVID-19 patients demonstrated that prostate diseases, which are linked to elevated androgen, are significant risk factors for severe COVID-19 and that genetic variants that increase androgen levels are associated with higher disease severity.

Dr. Goodarzi will discuss how these findings offer insights on the basis of differential susceptibility between men and women and suggest antiandrogenic drugs as candidate therapeutics for COVID-19.

Clonal Heterogeneity in Acute Lymphoblastic Leukemia at Diagnosis and During Chemotherapy Treatment Detected by Single-Cell Sequencing

Acute lymphoblastic leukemia (ALL) is an aggressive leukemia that occurs most frequently in children and is characterized by the presence of few chromosomal rearrangements and additional mutations. In this webinar, the second in a “Meet the Authors” series sponsored by Mission Bio, Jan Cools of the VIB Center for Cancer Biology in Leuven, Belgium will discuss the application of single-cell analysis to determine the clonal heterogeneity of the leukemia cells of ALL cases at diagnosis.

Dr. Cools’ lab used single-cell targeted DNA sequencing (Tapestri, Mission Bio) and single-cell RNA-sequencing (10x Genomics) to determine the clonal heterogeneity of the leukemia cells of 20 ALL cases at diagnosis and monitored the clonal evolution during chemotherapy treatment. Specifically, the lab designed a custom ALL panel and obtained accurate single-nucleotide variant and small insertion-deletion mutation calling for 305 amplicons covering 110 genes in about 4400 cells per sample and time point. Bone marrow and/or blood samples from 12 B-cell ALL and eight T-cell ALL patients were analyzed.

Dr. Cools will discuss how single-cell DNA amplicon sequencing is a sensitive assay to detect clonal architecture and evolution of the malignant cells in ALL, and present his findings published in the Blood paper, “Single-cell DNA amplicon sequencing reveals clonal heterogeneity and evolution in T-cell acute lymphoblastic leukemia.”

Epigenetic Patterns in a Complete Human Genome

The completion of the first telomere-to-telomere human genome, T2T-CHM13, enables exploration of the full epigenome, removing limitations previously imposed by the missing reference sequence. Existing epigenetic studies omit unassembled and unmappable genomic regions, such as centromeres, peri-centromeres, acrocentric chromosome arms, sub-telomeres, segmental duplications, and tandem repeats.

In this webinar, Ariel Gershman, a doctoral candidate at the Johns Hopkins School of Medicine, will discuss how she and her team leveraged the new assembly to measure enrichment of epigenetic marks with short reads using k-mer assisted mapping methods. This granted array-level enrichment information to characterize the epigenetic regulation of these satellite repeats. Using nanopore sequencing data, the team generated base-level maps of the most complete human methylome ever produced. They examined methylation patterns in satellite DNA and revealed organized patterns of methylation along individual molecules.

When exploring the centromeric epigenome, Gershman and colleagues discovered a distinctive dip in centromere methylation consistent with active sites of kinetochore assembly. With long-read chromatin accessibility measurements (nanoNOMe) paired to CUT&RUN data, the team found the hypomethylated region was extremely inaccessible and paired to CENP-A/B binding. With long reads, they interrogated allele-specific, long-range, epigenetic patterns in complex macro-satellite arrays, such as those involved in X chromosome inactivation. Using the single-molecule measurements, the team clustered reads based on methylation status alone, distinguishing epigenetically heterogeneous and homogeneous areas. The analysis provides a framework to investigate the most elusive regions of the human genome, applying both long- and short-read technology to grant new insights into epigenetic regulation.

NanoGBS: A Miniaturized Procedure for Genotyping By Sequencing Library Preparation

High-throughput reduced-representation sequencing (RRS)-based genotyping methods, such as genotyping-by-sequencing (GBS), have provided attractive genotyping solutions in numerous species. In this webinar, Davoud Torkamaneh, assistant professor at Université Laval, will discuss NanoGBS, a miniaturized, eco-friendly method for GBS library construction.

Using acoustic droplet ejection technology (Echo 525 Liquid Handler), NanoGBS libraries were constructed in tenfold smaller volumes compared to standard methods (StdGBS) and led to a reduced use of plastics of up to 90 percent. A high-quality DNA library and an SNP catalog were obtained with extensive overlap in SNP loci (96 percent) and 100 percent agreement in genotype calls compared to the StdGBS dataset with a high level of accuracy (98.5 percent). Combining NanoGBS library preparation and increased multiplexing can reduce genotyping cost per sample by 72 percent. This approach may greatly facilitate the adoption of marker applications where extremely high throughputs are required and cost is limiting.

Laboratory Adoption and Clinical Considerations for Prenatal Cell-Free DNA Screening for Common Aneuploidies

Cell-free (cf)DNA screening of pregnancies (also known as non-invasive prenatal testing or NIPT) is a transformative technology that is becoming routine for all pregnancies. Laboratories are potentially faced with adding a new technological approach in order to add NIPT to their repertoire of assays. Laboratories may choose from whole-genome NGS methods or more targeted methods. Furthermore, there are evolving regulatory requirements, a lack of test standardization around the world, and few validation studies targeting rare disorders. Clinical laboratory directors also need to anticipate the complexities of interpreting results from an inconclusive finding or disentangling biological considerations such as placental mosaicism from analytical performance considerations. However, NIPT is still a screening test, and thus confirmation by amniocentesis or chorionic villus sampling and diagnostic testing is required.

In this webinar, expert panelists, Jillian Buchan, PhD FACMG; Glenn Palomaki PhD; Kaarel Krjutškov PhD; and Russell Garlick, PhD will discuss recent experiences adopting NIPT testing for routine use, designing and executing complex validation studies, and interpreting unexpected results.

Panelist presentations will be followed by a discussion of current topics and audience questions.

Lessons Learned From Developing a Liquid Biopsy for Infectious Diseases

The use of next-generation sequencing (NGS) technologies in the field of infectious diseases has transformed the way pathogens are detected and characterized. Metagenomic sequencing provides a comprehensive and high-resolution analysis of microbial genetic material including bacteria, fungi, viruses, and parasites that is independent from microbial culture. The main challenge of developing a metagenomic sequencing assay is the efficient and unbiased recovery of microbial nucleic acids from degraded samples.

The Karius Test is a liquid biopsy that can non-invasively and rapidly detect over 1,000 pathogens from a single blood sample. When developing the Karius Test, scientists at Karius not only encountered challenges unique to metagenomics but unique to the biomarker that makes the test non-invasive; microbial cell-free DNA (mcfDNA). These challenges include working with degraded samples, unbiased detection of all mcfDNA in the sample, removing host and contaminant nucleic acid, and a streamlined workflow that accommodates a fast turnaround time. Tecan’s patented NGS library preparation technologies have supported laboratories like Karius to develop transformative genomic assays that uncover insights from even the most challenging samples.

In this webinar, Dr. Tim Blauwkamp, Chief Scientific Officer at Karius will discuss:

  • Challenges in developing a cell-free DNA metagenomic sequencing assay.
  • Approaches to solving these challenges for a liquid biopsy test for infectious diseases.
  • Collaboration with Tecan to recover fragments efficiently and without bias in degraded samples.

Tecan genomics reagents are for Research Use Only. Not for diagnostic procedures.

The Karius Test was developed and its performance characteristics determined by Karius. This test has not been cleared or approved by the FDA, nor is it required to be. The Karius laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA ‘88) and is accredited by the College of American Pathologists (CAP) to perform high-complexity clinical laboratory testing.
