Recent advancements in genetic research have led to a groundbreaking method called GoT-ChA. GoT-ChA stands for Genotyping of Targeted loci with single-cell Chromatin Accessibility. A recent publication in Nature details this innovative technique. It shows how gene mutations can disrupt the normal packaging of DNA. These disruptions lead to epigenetic changes that can drive malignancy.
The team of researchers from Weill Cornell Medicine and the New York Genome Center is leading this study. They have provided biologists with a powerful tool. This tool offers insights into various fields of investigation. It is particularly useful in understanding the origins and mechanisms behind cancer development.
Dr. Dan Landau is a leading figure in the study and a professor at Weill Cornell Medicine. He emphasizes the importance of this new method. It uncovers intricate links between mutations and epigenetic alterations. These links play pivotal roles in conditions such as cancer.
GoT-ChA excels at analyzing individual cells with high precision. Traditional methods work on bulk samples containing mixed cell types. By combining genotyping with chromatin accessibility mapping, researchers can gain a comprehensive view of a cell’s epigenetic state.
Empowering Research through Single-Cell Profiling
This innovative approach is part of a series of single-cell profiling techniques developed by Dr. Landau’s research group. Single-cell multi-omics methods are cutting-edge technologies. They allow scientists to characterize DNA mutations and gene activity patterns. These methods help in identifying cell-surface proteins. They also reveal other layers of information within individual cells simultaneously.
The integration of GoT-ChA with other single-cell profiling methods opens up new avenues for understanding complex biological processes at a cellular level, explains Dr. Franco Izzo, one of the co-leads on this pioneering study.
GoT-ChA has been applied to study rare blood cancers like polycythemia vera and myelofibrosis. This has unveiled crucial insights. It shows how mutations in the JAK2 gene contribute to disease progression. These mutations induce significant epigenetic changes that disrupt normal cellular functions.
