Cell-Free Chromatin: Rethinking the Foundations of Biology

Translational Research Laboratory (Estd. 2009)

A New Biology emerges after cell death:The critical role of cell-free chromatin in health and disease and mammalian evolution

The Translational Research Laboratory (TRL) was established to bridge fundamental scientific discoveries and their application in patient care. It integrates laboratory research with clinical observations to identify disease mechanisms and therapeutic strategies.

Our Research

Life depends on the daily death of hundreds of billions of cells. Yet, what happens to the genetic material released from these dying cells remains one of biology's least explored questions. Our laboratory investigates cell-free chromatin particles released by dying cells and their effects on living cells. We explore how these particles enter healthy cells, alter cellular function, and contribute to genomic instability, inflammation, ageing, cancer, metastasis, and treatment toxicity. Our research examines their assembly into autonomous satellite genomes, raising questions about non-coding DNA, horizontal gene transfer, genome plasticity, and evolution. We also investigate extracellular redox therapy using ultra-low doses of resveratrol and copper to neutralize these particles. Our vision is to establish cell-free chromatin biology as a biomedical field connecting cell death with health, disease, evolution, and innovative therapeutic opportunities.

Research Themes
Research theme 1.

Cell-free chromatin particles as drivers of evolutionary change

Together, these four papers propose that circulating cell-free chromatin particles (cfChPs) released during cell death are biologically active mobile genetic elements, not inert debris. They demonstrate that cfChPs can enter recipient cells, function as autonomous “satellite genomes,” mediate horizontal transfer of genetic information across cellular, species, and kingdom boundaries, mobilize transposable elements, and reveal evolutionary information encoded within non-coding DNA, with potential implications for genomic instability, disease, ageing, and mammalian evolution.

Research theme 2.

Cell-free chromatin particles as pathological entities

Our research shows that extracellular cfChPs can readily enter healthy cells, reshape cellular function, and influence processes ranging from genomic instability and inflammation, to ageing, cancer, metastasis, and treatment-related toxicity.

Research theme 3.

Therapeutic Strategies: Neutralisation of Cell-free Chromatin

These studies establish the scientific rationale and translational potential of the pro-oxidant combination of resveratrol and copper (R–Cu). They demonstrate that R–Cu generates reactive oxygen species that selectively deactivate extracellular cell-free chromatin particles (cfChPs), thereby preventing their pathogenic effects. Across experimental models, R–Cu reduced chemotherapy toxicity, radiation-induced bystander effects, endotoxin sepsis, ageing and neurodegeneration, and systemic dissemination of oncogenic material. Clinical studies and exploratory trials in COVID-19, oral cancer, gastric cancer, multiple myeloma, and glioblastoma showed reduced treatment-related toxicities and attenuation of malignant hallmarks, supporting cfChP deactivation as a novel therapeutic strategy.
