Unlocking Cancer Insights: Introducing the R2 Platform


Every year, millions of people are diagnosed with cancer — a disease that, despite its name, is not one condition but thousands. Understanding why tumors behave differently from patient to patient is one of the most pressing challenges in modern medicine. A major breakthrough came with The Cancer Genome Atlas (TCGA), a landmark project that molecularly mapped over 30 types of cancer across thousands of patients. But having data is only half the battle. Making sense of it — quickly, reliably, and without needing a team of bioinformaticians — is where progress stalls.

That's the problem R2 was built to solve.

R2 is a free, browser-based platform that puts powerful cancer genomics analysis in the hands of any researcher or clinician, no coding required. Drawing on TCGA RNA-seq and clinical data from 31 cancer types, R2 lets you ask — and answer — complex biological questions in minutes.

Here's what you can do with it:

  • Compare gene activity across cancer types and patient groups — See how a gene of interest behaves in tumor versus normal tissue, or across clinical subgroups like cancer stage, tumor grade, or other patient characteristics.
  • Link gene expression to patient outcomes — Explore whether high or low expression of a gene is associated with better or worse survival, helping pinpoint candidates for new diagnostic or therapeutic targets.
  • Discover what's driving a tumor subtype — Identify the most significantly over- or underexpressed genes in any cancer group, offering a fast route to hypothesis generation.


R2 is already making an impact: it has been cited in more than 2,700 PubMed-listed publications, reflecting its value to the global research community. Whether you're validating a target gene, exploring a new hypothesis, or simply trying to understand the molecular landscape of a cancer type, R2 provides the tools to do it — intuitively and openly.

"Who Survives, and Why?" — Using Kaplan-Meier Analysis to Link Gene Expression to Patient Outcomes

 There's a moment in every cancer biologist's research when the question shifts from what is this gene doing? to does it actually matter for patients? That shift used to require a statistician, a clinical dataset, and a lot of back-and-forth. R2 collapses all of that into a single afternoon. The Kaplan-Meier module in R2 is built for exactly this question. A Kaplan-Meier curve is one of medicine's most powerful visual tools — it shows you, over time, what fraction of patients in a group are still alive (or relapse-free). When you split patients into two groups — say, high versus low expression of your favourite gene — and their survival curves diverge dramatically, you feel it in your stomach. That divergence is a signal. Here's how a typical session goes. You've been studying a receptor gene that you suspect is linked to poor prognosis. You open R2, select a neuroblastoma dataset with survival annotation, and navigate to the Kaplan-Meier module. You choose to ...

"Finding the Axes of Variation" — Understanding Your Data with Principal Component Analysis

 There's a thought experiment that helps explain what Principal Component Analysis does. Imagine you're trying to describe the differences between a large group of people, and you have a thousand measurements for each person — height, weight, age, dozens of blood markers, hundreds more. That's an impossibly high-dimensional space. PCA's job is to find the most important directions of variation in that space and let you look along those directions instead. In genomics, the same logic applies. You have thousands of gene expression measurements per sample. PCA collapses that complexity into a small number of "principal components" — axes that capture the most variance in the dataset. The first principal component captures the most variation of all. The second captures the most of what remains, and so on. When you plot your samples along the first two or three of these axes, you're looking at a compressed but surprisingly faithful summary of the whole datase...

Plotting updates for the open online R2platform. The data science platform for biomedical researchers

Image
  Ploting updates for the R2platform We have been working hard to bring you the latest update in the R2 genomics analysis and visualization platform ( https://r2.amc.nl ); the goto web-tool for biomedical researchers to test their hypotheses on public omics data, without the need for bioinformatics or coding expertise. In the latest update, we have made substantial changes to many of the plots that can be produced within R2. Many of the adaptable parameters have now become interactive and are placed under the 'gears' icon. The 'gears' icon Let's have a look at a gene within one of the many resources that are publicly available in R2. We will look at the GATA3 gene in an integrated resouce where samples from both GTEx as well as the TCGA have been integrated and 'batch corrected' to get an immersive view of expression in normal as well as cancer samples. We first select our resource of interest by clicking on 'select a data set'. and then find the ...
