The research team led by Professor Kim Yong-ki at Sookmyung Women's University has made a groundbreaking discovery regarding the precise regulation of chromosome condensation, crucial for ensuring that genetic information is accurately distributed during cell division. This study is particularly significant as errors in chromosome condensation can lead to various diseases, including cancer. The team indicated that understanding these mechanisms could pave the way for new therapeutic strategies targeting cell division-related disorders.

Specifically, the researchers identified a dynamic transition process involving 'active markers' that are removed and 'inhibitory markers' that accumulate at the right moment during cell division. The study found that the active marker, which is formed by the protein arginine methylation enzyme CARM1, is eliminated with the onset of mitosis, with the mediating enzyme identified as KDM4A. This discovery elucidates how the switch from active to inhibitory markers occurs at a molecular level, contributing to the structural changes necessary for chromosome condensation.

Professor Kim emphasized the importance of their findings, stating that the meticulous switching between histone active markers and inhibitory markers at the appropriate time during cell division is a significant advance in understanding not only the mechanisms of cell division but also in formulating next-generation cancer therapies. This research was led by doctoral student Jo Ye-na and published in the prestigious journal Advanced Science, signaling considerable academic recognition for their work.
