Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a revolutionary technology that can transform colon cancer cells into normal-like cells without destroying them. This innovative approach marks a significant departure from traditional cancer treatments that often lead to severe side effects and the risk of recurrence.
The research team, led by Professor Kwang-Hyun Cho of the Department of Bio and Brain Engineering, has introduced a novel method that targets the root causes of cancer development. Instead of focusing on eradicating cancer cells, which can lead to resistance and return of the disease, this method aims to revert cancer cells to their normal state. “The fact that cancer cells can be converted back to normal cells is an astonishing phenomenon. This study proves that such reversion can be systematically induced,” Cho remarked.
The researchers explain that during the transformation from normal cells to cancerous ones, cells regress along the differentiation trajectory. This process, known as cell differentiation, is how normal cells mature into specific functional types. By understanding and manipulating this process, the team was able to create a digital twin of the gene network involved in cell differentiation.

This computational model allowed them to simulate and analyze complex gene interactions. Through these simulations, they identified master molecular switches key regulators responsible for driving the differentiation process. By targeting these switches, the team could steer colon cancer cells back into a normal-like state. Their findings were validated through molecular experiments, cellular studies, and animal trials, demonstrating the effectiveness of this approach.
The implications of this research are profound. This technology could lead to the development of a new class of cancer treatments that minimize side effects and reduce the likelihood of recurrence. “This research introduces the novel concept of reversible cancer therapy by reverting cancer to normal cells. It also develops foundational technology for identifying targets for cancer reversion through the systematic analysis of normal cell differentiation trajectories,” Cho elaborated.

The researchers believe that this method could be applied to other types of cancer as well. By using the same computational modeling technology on different cancer gene networks, they hope to identify similar molecular switches in other cancer types. This could pave the way for more targeted and effective cancer therapies.
The KAIST team’s research has been published in the journal Advanced Science. Their work represents a significant step forward in the field of oncology, offering hope for new treatments that are both effective and less harmful to patients. Traditional cancer treatments often cause serious side effects and carry the risk of cancer returning. This new approach aims to address these issues by changing the way we think about and treat cancer.
In addition to their work on colon cancer, the researchers also used their digital modeling program to discover master regulators in the hippocampus region of mouse brains. These regulators play a role in the cellular differentiation process and could potentially be used to study and reverse the spread of brain cancer.
