What to know about Biotechnology Innovation

Researchers at KAIST have developed a technology called ROOT to identify and control the molecular circuits that cause biological states to become irreversible. The study, published in PNAS, suggests this method could lead to new treatments for cancer and aging by restoring abnormal cells to their original states.

What happened

New ROOT method charts a path to reversing biological changes once thought irreversible Sadie Harley Scientific Editor Robert Egan Senior Editor Once a cell has locked into an abnormal state—the way cancer cells do—can it ever be restored to normal?

Why it matters

A KAIST research team led by Professor Kwang-Hyun Cho of the Department of Bio and Brain Engineering has, for the first time, identified the causal circuits responsible for irreversibility in intracellular molecular networks and developed a fundamental…

Common ground

The paper is published in the journal Proceedings of the National Academy of Sciences.

Claim 1: “Using ROOT, the research team successfully simulated the process in which cells maintain a signal even after an external stimulus is removed, allowing them to identify a set of core circuits that cause irreversibility, which they defined as the 'irreversibility kernel.'”
SINGLE SOURCE
One web search result ('New ROOT method charts a path...') directly corroborates the claim regarding the simulation of signal maintenance and the 'irreversibility kernel'. Other results are irrelevant.
