Lymphoma Subtyping Test (LST) CodeSet – RUO
The LST CodeSet contains probes for the 20 genes within the LST signature, 15 target genes and 5 reference genes.
The signature was originally identified by performing gene expression profiling of DLBCL samples using microarrays (Alizadeh et al, 2000). The gene expression profiles indicated two different stages of B-cells differentiation: germinal center (GCB) and activated B cell based (ABC) based on the cell of origin and distinct mechanisms of oncogenesis. This signature was later refined to 20 genes using the FFPE tissues on the nCounterAnalysis system (Scott et al, 2014).
NanoString developed a multiplex gene expression assay on the nCounter Analysis System that can identify the cell of origin (COO) subtypes (ABC-type or GCB-type) of DLBCL: the 20-gene assay was trained using 51 FFPE biopsies; the locked assay was validated using an independent cohort of 68 FFPE biopsies. Comparisons were made with COO assignment using the original COO model on matched frozen tissue. A linear predictor score (LPS) calculated as the weighted sum of the 15 normalized target genes compared to pre-defined thresholds determine the DLBCL cell-of-origin subtype.
Prosigna Score / ROR Score:
The ROR Score has been validated to predict the risk of recurrence of disease in ER+ breast cancer after surgery and treatment with 5 years of endocrine therapy. The ROR score depends upon the biology of the intrinsic subtypes, the proliferation score of the tumor, and the tumor size as shown in the equation below:
ROR = aRLumA + bRLumB + cRHer2 + dRBasal + eP + fT
Each of the R variables in the equation above indicate the Pearson correlation coefficient of the PAM50 expression profile for the tumor compared to each of the prototypical centroids for the intrinsic subtypes shown in the heatmap below. P is the proliferation score, which is the average gene expression profile of genes associated with cell-cycle progression and T is the tumor stage.

GeoMx DSP COVID-19 Protein and RNA Analysis
Rapidly perform high-plex spatial analyses of the host response in FFPE or fresh frozen tissue using the GeoMx Digital Spatial Profiler (DSP). NanoString’s GeoMx DSP platform enables high-plex protein and RNA experiments in key areas of biology such as molecular response, cellular (immune) response, tissue damage, and drivers of individual susceptibility to severe forms of disease.
The GeoMx COVID-19 Immune Response Atlas, a ~1,850-plex RNA assay, enables spatial studies of the SARS-CoV-2 virus and host response. RNA targets include COVID-19 receptors and proteases, pulmonary alveolar type I and II markers, lung biology markers, viral response markers, and SARS-CoV-2 probes. RNA targets are profiled simultaneously using the GeoMx DSP and an Illumina next-generation sequencer (NGS) for readout. Users can run ACD RNAscope™ probes alongside GeoMx RNA probes to identify regions of interest.
A five-antibody custom, ready-to-go protein panel, with receptor, protease, and viral markers is available through the GeoMx Technology Access Program or for order through Abcam. This COVID-19 GeoMx-formatted Antibody is run with the 20-plex GeoMx Immune Cell Profiling Core (plus controls) with readout on the nCounter Analysis System. Users can add up to six 10-plex modules including the Immune Activation Status, Immune Cell Typing, and/or Cell Death modules to more deeply profile proteins involved in T cell activation and cell death. NanoString scientists can recommend commercially-available markers for lung epithelium, nasal epithelium, immune response markers, and the viral spike protein.
AUTOIMMUNE DISEASE AND CHRONIC INFLAMMATORY DISEASE COVERAGE
Chronic inflammatory disorder that impacts the lining of joints.
Chronic inflammatory of the digestive tract.
Autoimmune disease is where the immune system mistakenly attacks the insulin-producing cells of the pancreas
Demyelinating disease that disrupts communication with the nervous system.
Immune-mediated disease that causes skin cells to rapidly build up on the surface of the skin
Certain treatments and infections have been reported to interfere with the immune system and induce a series of autoimmune disease or adverse immune-related events.
