NanoString Highlights Groundbreaking Spatial Genomics Research Using Expanding Portfolio of GeoMx High-Plex RNA Atlas Products at 2020 Advances in Genome Biology and Technology (AGBT) Conference

February 20, 2020 Off By BusinessWire

Presenting Ten Research Studies using the Cancer Transcriptome Atlas to Discover Novel Biomarkers and First Data from Forthcoming Whole Transcriptome Atlas

Unveiling GeoMx DSP Roadmap at 2nd Annual Spatial Genomics Summit on Sun February 23rd

SEATTLE–(BUSINESS WIRE)–NanoString Technologies, Inc. (NASDAQ:NSTG), a leading provider of life science tools for discovery and translational research, today announced ten scientific studies utilizing the GeoMx™ Digital Spatial Profiler (DSP) that will be showcased at the 2020 Advances in the Genome Biology and Technology (AGBT) conference being held at the JW Marriott in Marco Island, Florida. These studies span cancer translational research to neuroscience discovery applications, illustrating the platform’s flexibility and opportunity to spatially map distinct cell types and quantitate biological activity. NanoString will also be hosting the 2nd Annual Spatial Genomics Summit on Sunday, February 23rd from 12 – 4pm ET. Attendees do not need to be registered for AGBT to attend the Summit.

The GeoMx Digital Spatial Profiler provides researchers high throughput, high multi-plex, spatial profiling of RNA and protein targets in a variety of sample types, including both fresh frozen and formalin-fixed, paraffin-embedded (FFPE) tissue sections. GeoMx DSP is currently available for read-out using NanoString’s nCounter Analysis System, allowing analysis of up to 96 proteins and 96 RNA targets. Beginning mid-2020, GeoMx DSP will be enabled to read-out on Illumina’s Next Generation Sequencers (NGS), which will increase the number of RNA targets that can be analyze by approximately twenty-fold. First NGS-enabled assay will be Cancer Transcriptome Atlas for human samples, which profiles more than 1,800 genes within oncology and immune pathways. This will be followed in 2021 with launch of the Whole Transcriptome Atlases for human and mouse.

“As one of the first labs in the world to have acquired the GeoMx DSP platform, we are enthusiastic about the potential to discover novel biology with the system,” said Alex Swarbrick Ph.D., Garvan Institute of Medical Research, Sydney, Australia. “We used the GeoMx Whole Transcriptome Atlas to spatially characterize distinct cell types in triple negative breast cancer. These data allowed us to track the spatial heterogeneity of cancer signaling pathways and of T cell subsets, leading to insights inaccessible to bulk or single-cell RNA sequencing.”

“2020 is shaping up to be the breakthrough year for spatial biology,” said Brad Gray, president and CEO of NanoString. “At the AGBT conference, researchers will highlight the powerful new capabilities that will be unlocked using NGS read-out, including our Cancer Transcriptome and Whole Transcriptome Atlases. I’d like to thank all of our customers and collaborators that have worked so diligently to make such groundbreaking research a reality.”

At AGBT 2020, studies performed by leading academic researcher centers demonstrate three major applications for GeoMx DSP:

1.

Discovering novel spatial biomarkers that are not readily detectable by traditional bulk profiling

 

Spatial landscape of the immune microenvironment in metastatic prostate cancer using GeoMx™ Digital Spatial Profiler

Pete Nelson, MD, et al., Fred Hutchinson Cancer Research Center, Seattle, WA USA

Used GeoMx DSP Cancer Transcriptome Atlas to interrogate tissue microarrays of metastatic prostate cancer samples and characterize immune responses. Spatial analysis revealed intra-patient heterogeneity that would not have been readily apparent from bulk RNA profiling experiments.

 

 

Spatial proteomic characterization of the tumor and immune microenvironment reveals features associated with response to neoadjuvant HER2-targeted therapy

Katherine McNamara et al., Stanford University, Palo Alto, CA, USA

Used spatial proteomic analysis of biopsies from on-treatment HER2+ breast cancer patients to stratify responders v. non-responders early during a course of neoadjuvant HER2-targeted therapy. GeoMx analysis allowed unique segmentation of cell populations to provide insight into the effect of innate immune markers, ER status, and PAM50 subtype on treatment response.

 

 

Identification of cell type-specific RNA biomarker candidates in melanocytic tumors using GeoMx Digital Spatial Profiling

Maija Kiuru, MD, Ph.D., University of California, Davis, CA, USA

GeoMx Cancer Transcriptome Atlas analysis revealed microenvironment-specific expression of a novel cell-type specific biomarker, DAMP, in response to early melanoma development. This marker may allow for more sensitive detection of melanoma via patch biopsy.

 

 

Single-nucleus RNA-seq reveals distinct intratumoral transcriptomic heterogeneity in treatment-naïve and chemoradiotherapy-treated primary pancreatic ductal adenocarcinoma

William Hwang, MD, Ph.D., et al. et al., Broad Institute, Cambridge, MA, USA

GeoMx Cancer Transcriptome Atlas and Whole Transcriptome Atlas applications were used to profile tumor, fibroblast, and immune compartments in Pancreatic ductal adenocarcinoma (PDAC) samples from twelve patients. Differential gene expression was measured in tumor and fibroblast compartments between treatment groups and by levels of immune infiltration.

 

 

Spatial Profiling of the Immune Landscape of Solid Tumors Treated with Low Dose Radiation and Immunotherapy Using High Plex RNA Profiling with the GeoMx™ Platform

Krisztian Homicsko, MD, Ph.D., et al., Ludwig Institute for Cancer Research, Lausanne, Switzerland

This project interrogated gene expression changes associated with low-dose radiation immunogenic induction therapy in ovarian cancer. GeoMx Cancer Transcriptome Atlas analysis revealed a pretreatment microenvironment associated with favorable response to therapy, and allowed in depth analysis of needle core biopsies, providing important spatial information in samples that would not have been ideal for bulk transcriptomic assays.

 

 

Localizing and quantifying the immune contexture of human glioma with GeoMx™ high -plex RNA profiling

Troy McEachron, MD, et al., University of Southern California, Los Angeles, CA, USA

Combined single cell RNA sequencing with GeoMx Cancer Transcriptome Atlas analysis to characterize immune cell distribution in glioma samples. GeoMx DSP demonstrates that synchronizing digital pathology and bioinformatics provides layers of insight that conventional methods couldn’t.
