The Mechano-Genomics Group was initiated with the recruitment of G.V.Shivashankar as a Full Professor to the Department of Health Sciences and Technology, ETH Zurich, jointly with the Paul Scherrer Institute (PSI). Shiva’s research laboratory is located at PSI and has started its activities in January 2020. On the computational side, we closely collaborate with Caroline Uhler's group at MIT.
News and Highlights
En utilisant des stimulations mécaniques, les scientifiques du PSI ont reconverti des cellules de tissus conjonctifs en cellules semblables à des cellules souches, avant de les transplanter dans des tissus cutanés lésés. Cela a permis d’accélérer la régénération de la peau et la cicatrisation des plaies.
Our research group is interested in understanding the mechano-genomics of cellular ageing and how ageing cells and ageing related disease cells, such as cancer and fibrotic cells, can be reprogrammed and rejuvenated by mechanotransduction. Towards this, we also develop novel imaging-AI based mechano-genomic biomarkers as fingerprints for cells health and disease.
Recent studies have highlighted that cellular ageing is accompanied with the loss of mechanical integrity of cells, which may result in a progressive decline of cellular organelle functions as well as loss of tissue integrity and onset of various diseases including cancer, fibrosis, and neurodegeneration. A major challenge going forward is to understand the underlying mechanisms of cellular ageing and develop robust methods to rejuvenate ageing cells. In recent years our group has made significant contributions towards an in-depth understanding of the mechano-genomic mechanisms underlying the coupling between the extra-cellular matrix, 3D chromatin organization, and gene expression that is critical to understand cellular ageing, develop methods to rejuvenate ageing cells and implement imaging-AI based chromatin biomarkers for cell-fate decisions. Our results also provide novel avenues to explore the mechano-genomic coupling between cellular ageing, reprogramming and cancer within the tissue microenvironment. Pursuing these avenues has been our priority in research, education, and technology and knowledge transfer.
Our group’s research program is highly interdisciplinary and uses advanced light microscopy, microfabrication, functional genomics, theoretical modeling, and machine learning methods. Importantly, our research program has also drawn in domain experts in mechanobiology, genomics, bioengineering, theoretical physics, computer science and clinicians. Building on our current strengths, our ongoing and future research is focused on three major themes:
- Regulation of genome organization and gene expression by nuclear mechanotransduction during cellular ageing
- Mechano-genomic regulatory modules in cellular reprogramming and rejuvenation
- Single-cell imaging-AI based chromatin biomarkers for cellular ageing and cancer
Clinical trials: On the medical side, in collaboration with the Center for Proton Therapy at PSI, we have started a clinical trial to analyze if our imaging-AI based chromatin biomarkers of peripheral mononuclear blood cells, obtained from liquid biopsies, could help determine the efficacy and toxicity of proton radiation therapy for treating various cancers in human patients. In addition, together with the local Health Center in Brugg, Switzerland, we have started a clinical trial to assess if our chromatin biomarkers could provide robust methods for early cancer diagnostics. We plan to expand on these ongoing successful clinical trials in future.
Technology transfer: Our research program on mechano-genomics has also resulted in the founding of a company “FOCAL Biosciences” together with Apollo Ventures and PSI/ETH Zurich. The goal of this company is to identify lead compounds for cellular reprogramming in the context of ageing related diseases. FOCAL Biosciences aims to use our group’s knowhow to develop a drug discovery platform using the “mechano-genomic principles underlying fibroblast cell-state transitions and the imaging-AI based chromatin biomarkers”.
In our projects, we have multiple openings for PhD students and postdoctoral fellows with a strong background in molecular and cell biology, genomics, bioengineering, advanced light microscopy/image analysis and computational biology. >>> More Information (FDF)
