Synthetic Biology Revolution

The USC Dornsife College of Letters, Arts and Science has introduced CReATiNG, a groundbreaking method in synthetic biology, which significantly simplifies and reduces the cost of creating synthetic chromosomes from yeast DNA. This technological advancement promises to revolutionize various fields including medicine, biotechnology, and space exploration, as reported by SciTechPost.com.

USC Dornsife’s CReATiNG method marks a significant leap in synthetic biology by streamlining the process of constructing synthetic chromosomes. This approach is expected to drive considerable progress in a range of scientific and medical areas.

Innovative Technique in Synthetic Biology

Developed by researchers at USC Dornsife, CReATiNG (Cloning Reprogramming and Assembling Tiled Natural Genomic DNA) offers a more straightforward and economical method for assembling synthetic chromosomes. This innovation could greatly enhance the field of genetic engineering, with wide-ranging implications in medicine, biotechnology, biofuel production, and space exploration.

Easing the Process of Chromosome Assembly

CReATiNG employs a technique of cloning and reassembling segments of natural DNA from yeast. This enables the creation of synthetic chromosomes capable of substituting their natural counterparts in cells. The method allows for the combination of chromosomes from various yeast strains and species, alteration of chromosome structures, and simultaneous deletion of multiple genes.

Ian Ehrenreich, professor of biological sciences at USC Dornsife and the lead researcher, highlighted that CReATiNG significantly surpasses existing technologies. He stated, “CReATiNG allows for complex genetic reprogramming of organisms in ways that were previously thought to be unachievable, even with cutting-edge tools like CRISPR.” He emphasized the potential of this method in enhancing our fundamental understanding of life and its applications in synthetic biology. The research is set to be published on December 20 in Nature Communications.

Advancements in Genetic Engineering

Synthetic biology has been recognized as a field that enables scientists to control living cells like yeast and bacteria, enhancing our understanding of their functions and enabling the production of beneficial compounds such as new medications.

Ehrenreich noted that synthetic genomics, a branch of synthetic biology involving the synthesis of entire chromosomes or genomes, has traditionally relied on constructing these components from chemically synthesized DNA segments, a process that is both labor-intensive and expensive.

CReATiNG, as elucidated by Agilent postdoctoral fellow Alessandro Coradini, the study’s first author, offers a new approach by utilizing natural DNA segments for assembling entire chromosomes. This method democratizes advanced genetic research, lowering both costs and technical hurdles, and facilitating new scientific and medical breakthroughs.

Potential Applications of CReATiNG

The implications of CReATiNG are particularly noteworthy in biotechnology and medicine. It could lead to more efficient production of pharmaceuticals and biofuels, advancements in cell therapies for diseases such as cancer, and new methods for environmental bioremediation, like creating pollutant-consuming bacteria.

The technique also holds promise for applications in space exploration, potentially enabling the development of microorganisms or plants suited for life in space stations or during extended space missions. However, the researchers note that this application would require significant future research.

One key finding of the study is the observation that rearranging chromosome segments in yeast can significantly affect their growth rates, with some modifications causing up to a 68% increase or decrease in growth. This underscores the substantial impact of genetic structure on biological functions and opens new avenues for research in this area.

The study, titled “Building synthetic chromosomes from natural DNA,” will be published in Nature Communications with a DOI of 10.1038/s41467-023-44112-2.

The research team includes Ian Ehrenreich, Alessandro Coradini, Christopher Ne Ville, Zachary Krieger, Joshua Roemer, Cara Hull, Shawn Yang, and Daniel Lusk from USC Dornsife. It was funded by the National Science Foundation grant 2124400, National Institutes of Health grant R35GM130381, and an Agilent Postdoctoral Fellowship.
