The origin of many illnesses begins on the mobile degree and entails a number of molecular interactions. However, earlier strategies have struggled to precisely observe adjustments in particular person cells. Analyzing common values throughout 1000’s of cells made it difficult to detect the early alerts of illness.
Our college’s analysis staff has pioneered groundbreaking expertise that decodes the genetic blueprint inside a cell in 3D, akin to zooming in on Earth utilizing Google Earth. This innovation is poised to remodel analysis into complicated illnesses comparable to most cancers, dementia, and Parkinson’s illness.
KAIST introduced on March 4th that Professor Inkyung Jung’s analysis staff from the Department of Biological Sciences, in collaboration with Professor Yarui Diao’s staff at Duke University, has developed scHiCAR (single-cell Hi-C with assay for transposase-accessible chromatin and RNA sequencing). This is the world’s first ultra-high throughput & exact molecular map decoding expertise that concurrently analyzes gene expression (transcriptome), the epigenome, and the 3D genome construction inside a single cell.
The key to figuring out a cell’s state lies in how its genes function. Genes should not merely switches that activate and off. The future of a cell is set by which genes are literally lively (transcriptome), why they’re lively (epigenome), and inside what spatial construction they function (3D genome construction). Existing applied sciences required acquiring this info from totally different cells individually after which matching them afterward, which may result in the distortion or omission of refined adjustments.
The analysis staff launched ‘Trimodal Multi-omics’ expertise, an built-in precision evaluation technique that concurrently examines these three sorts of genetic info inside a single cell. By incorporating Artificial Intelligence (AI) evaluation, they considerably enhanced accuracy and reproducibility, culminating in a unified platform that reads inside mobile genetic info akin to a ‘single 3D map.’
Notably, the staff succeeded in decreasing the evaluation value to roughly $0.04 (approx. 50 KRW) per cell. Using this, they constructed a high-resolution molecular map of 1.6 million cells in mouse mind tissue. This means it’s now attainable to exactly establish when, the place, and inside what construction illness genes are turned on or off on the mobile degree.
The analysis staff utilized this expertise to mind tissue and the muscle regeneration course of, revealing distinct gene operation ideas throughout 22 main cell sorts. Notably, they efficiently tracked in real-time how the 3D construction of genes dynamically adjustments to affect cell destiny throughout muscle stem cell regeneration. This development is anticipated to put an important basis for creating therapy methods for growing older and incurable illnesses.
Professor Inkyung Jung remarked, ‘This analysis transcends mere commentary of cells; it opens the door to exactly studying and controlling the genomic blueprints inside them. It represents a major turning level in elucidating the developmental mechanisms of complicated illnesses like Parkinson’s and most cancers, in addition to figuring out goal factors for patient-specific new medication.’
The examine was printed on February nineteenth in the worldwide educational journal Nature Biotechnology (IF=46.9).

Meanwhile, this analysis was carried out with assist from the Suh Kyungbae Foundation, the Samsung Science and Technology Foundation, and the Basic Research Program and Bio-Medical Technology Development Program of the National Research Foundation of Korea (Ministry of Science and ICT).
