Illumina partners go beyond the genome, driving cancer breakthroughs using spatial transcriptomics, epigenomics, and proteomics
At AGBT, researchers reveal new findings from studies leveraging
"Unlocking the human genome has changed the face of cancer care and opened up demand for the next wave of biological insights," said
Illumina Spatial Technology decodes complex tissues with ease
The human lymphatic system is notoriously difficult to map due to its size and variability among individuals. Spatial technology holds promise to probe biomolecular signatures that can improve the diagnosis and prognosis of cancer and even explain how it metastasizes in the body.

"Our research as an NIH HuBMAP Tissue Mapping Center aims to shed light on the complex function of lymphatic vessels, which are exceptionally challenging samples due to their low adhesion, surrounding adipose tissue, and small size. Illumina Spatial Technology generated high-quality data from samples ranging from very small to quite sizable, producing the first ever whole transcriptome spatial datasets for human lymphatic collector vessels," said Vlachos. "The large capture area and serial sections helped us resolve single‑cell‑thick layers and reconstruct three‑dimensional representations of tissue organization with whole transcriptome capture at 1um resolution. Our institution and the broader research community can use these datasets to answer many possible research questions."
In another study conducted by Illumina researchers, Illumina Spatial Technology outperformed other competing technologies for improved sensitivity, higher resolution, and higher throughput at a lower cost.
The study mapped breast cancer progression across a range of precancerous to high-grade ductal carcinomas. Whole-transcriptome profiling revealed unexpected nuances of tumor microenvironments, including identification of a novel set of cancer-associated fibroblasts. Researchers found more than 2000 unique transcripts in each cell, showing an unprecedented level of sensitivity.
"Each tumor is unique and its gene expression is never uniform," said
Illumina 5-base solution delivers epigenetic context for cancer diagnostics
A team of researchers from
The researchers are seeking genomic alternative approaches. Existing translational research ctDNA assays can miss disease signals in very rare tumors such as Wilms and rhabdoid. Illumina's 5-base solution enabled simultaneous genomic and methylation profiling to add additional epigenomics signals that identify cases missed by conventional approaches.
Illumina 5-base whole genomes from renal cancer patients were tested in methylation-based classifiers and were able to predict the presence of rhabdoid tumors missed by genomics-only methods. Future work will expand 5-base profiling to additional FFPE and cfDNA samples, with the goal of training advanced machine learning models. These efforts may ultimately provide clinicians with more accurate diagnostic insights and improve outcomes for patients.
"Combining these molecular signals in a single, scalable process can help us develop non-invasive diagnostics for cancers," said
Integrated multiomics improves understanding of advanced ovarian cancer
Nearly 80% of ovarian cancers are diagnosed at advanced stages, where survival drops to about 30%. When caught early, survival exceeds 90%. For women presenting with an adnexal mass, accurately distinguishing between benign and malignant disease is critical to guiding appropriate referral and surgical care, yet current diagnostic tools lack sufficient accuracy to reliably support these decisions.
Bodour Salhia, PhD, a professor of cancer biology at the
"These findings create a multiomic framework for ovarian cancer research and lay the groundwork for an effective liquid biopsy in particularly challenging ovarian cancers with the potential to transform diagnostic practices and outcomes," said Salhia. "Layering the omics gave us a winning combination, providing more context for earlier cancer identification."
Illumina's 5-base solution allowed for sensitive, integrated genetic and methylation analysis of tumor samples without compromising specificity. The methylation signals separated malignant and benign samples better than traditional approaches, which can often fail to separate cell types.
The layered approach helped researchers establish parameters for targeted exploration of gene expression in spatial data. Using Illumina Spatial Technology, transcriptomic data helped to resolve signals driving false positive results.
Illumina Connected Multiomics accelerates sample-to-answer pipeline
Multimodal analytics from Illumina Connected Multiomics provides deeper insights and overcomes the fragmented, siloed views produced by isolated assays, empowering researchers with a new understanding of cancer mechanisms, tumor heterogeneity, and potential therapeutic targets.
