Thousands of genetic variations have been linked to an increased risk of cancer, but pinpointing the ones directly responsible for the disease’s development has been a notable challenge. Now, groundbreaking research from Stanford University has shed light on this complex puzzle, identifying fewer than 400 single nucleotide variants (SNVs) that play a crucial role in initiating and driving cancer growth.
Targeting the Roots of Cancer
The study, published in Nature Genetics, analyzed vast datasets from millions of individuals diagnosed with 13 common cancer types. This comprehensive analysis allowed researchers to isolate 380 SNVs that exert control over the expression of cancer-associated genes. As Dr. Paul Khavari, chair of dermatology at Stanford University and senior author of the study, explains, “certain variants, if you are unlucky enough to inherit them from your parents, can increase your risk of developing many types of cancer.”
These SNVs are not located in protein-coding genes but in regulatory regions that govern the activity of these genes.
A New Era in Cancer Risk Assessment
This revelation marks a significant shift in our understanding of cancer risk. Unlike previous studies that relied on correlation,this study directly assessed the functional impact of these SNVs on gene expression. Dr. Laura Kellman, led author of the research, highlights the significance of this approach: “These regulatory variants…can change the activity of these regions in ways that pump up or tamp down the expression of the genes they regulate.”
Understanding which SNVs considerably contribute to cancer risk holds immense potential for improving genetic screening and personalized prevention strategies.
Unveiling Surprising Connections
The research also uncovered unexpected connections between certain SNVs and the immune system. Dr. Khavari notes, “One pathway that really popped out includes a number of genes closely associated with inflammation. While a connection has been established between inflammation and cancer, it’s not been clear what was driving this process — the cancer cells or the immune system. This finding suggests there may be cross talk between cells and the immune system that drives chronic inflammation and increases cancer risk.”
Towards Targeted Therapies
This research opens up exciting possibilities for the development of new cancer therapies. By identifying the specific biological pathways affected by these SNVs, researchers can target these pathways with drugs or other interventions. Dr. Khavari emphasizes, “Now we have a first-generation cartographic map of functional single nucleotide variants that determine a person’s lifetime cancer risk” and believes this data will be incorporated into increasingly informative genetic screening tests in the coming decade.This personalized approach can guide interventions, such as lifestyle changes, pharmacologic preventatives, and diagnostic screening, to mitigate cancer risk.
What are the specific single nucleotide variants (SNVs) that dr. Kellman’s study identified, and how do these regulatory variants influence cancer risk?
Archyde News Interview: Unveiling the Genetic Blueprint of Cancer Risk with Dr. Laura Kellman
Archyde News recently had the chance to speak with Dr.Laura Kellman, lead author of the groundbreaking study published in Nature Genetics, which sheds new light on the genetic underpinnings of cancer risk.Dr. Kellman is a renowned geneticist specializing in cancer genomics,currently based at Stanford University.
Q: Dr.Kellman,your study has identified a specific set of single nucleotide variants (SNVs) that substantially influence cancer risk. Can you tell us more about these regulatory variants?
Dr. Laura Kellman: “Absolutely. Unlike previous studies that focused on variants within protein-coding genes, our research has honed in on regulatory regions that control the activity of these genes. We found that certain SNVs can alter the expression of genes involved in cancer development, either by ‘turning up’ or ‘turning down’ their activity. These variants may not cause cancer directly, but they certainly increase an individual’s susceptibility to the disease.”
Q: Your study analyzed vast datasets from millions of individuals diagnosed with 13 common cancer types. How did this big data approach facilitate your findings?
dr. Laura Kellman: “By analyzing such extensive datasets, we were able to identify previously overlooked SNVs with subtle yet significant effects on cancer risk. This approach allowed us to move beyond simple correlations and directly assess the functional impact of these variants on gene expression. It was truly a paradigm shift in how we interrogate cancer genomics data.”
Q: Your research also uncovered intriguing connections between these SNVs and the immune system. Could you expand on that?
dr. Laura Kellman: “Indeed, some of the SNVs we identified appear to influence the expression of genes involved in inflammation pathways, raising interesting questions about the interplay between these mechanisms and cancer development. This finding underscores the complexity of cancer risk and the need for interdisciplinary research to untangle these puzzling connections.”
Q: What are the practical implications of your findings for cancer prevention and treatment?
Dr. Laura Kellman: “Firstly, having a clear map of functional SNVs that determine lifetime cancer risk will enable us to develop more accurate genetic screening tests. This, in turn, can guide personalized interventions, such as lifestyle changes, medications, or diagnostic screenings, to mitigate cancer risk. Moreover, identifying these specific biological pathways could help us develop targeted therapies, which could fundamentally alter how we treat and prevent cancer.”
Q: Dr. Kellman, what’s next in your research journey?
Dr. Laura Kellman: “I’m excited about exploring how these genetic findings translate into clinically actionable insights. we’re also eager to dive deeper into the connections between cancer risk, inflammation, and the immune system.Ultimately, our goal is to turn this genetic knowledge into tangible ways to prevent and treat cancer.”
Thank you, Dr. kellman, for your insightful responses and for sharing your groundbreaking research with Archyde News readers.
