Researchers Reveal Molecular Mechanism of Ruthenium Complex Induced DNA Phase Separation

Chinese Academy of Sciences The phenomenon of “liquid-liquid” phase separation (LLPS) of biological macromolecules in living cells regulates many cell activities. DNA LLPS manipulates many important processes such as gene transcription, translation, and chromosome high-level structure assembly. Abnormity of DNA LLPS causes oncogene expression, genome inactivation, uncontrolled transcription activation and other cellular processes, which are directly related to fatal diseases. Recently, a research group led by Prof. LI Guohui from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. MAO Zongwan’s group from Sun Yat-Sen University, revealed the molecular mechanism of ruthenium complex induced DNA phase separation in living cells.

Study Sheds Light on Precise Personalized Hepatocellular Carcinoma Medicine

Chinese Academy of Sciences A research group led by Prof. PIAO Hailong from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) identified hepatocellular carcinoma (HCC) subtypes with distinctive metabolic phenotypes through bioinformatics and machine learning methods, and elucidated the potential mechanisms based on a metabolite-protein interaction network and multi-omics data. The study, published in Advanced Science on July 11, provides insights guiding precise personalized HCC medicine. Metabolic reprogramming, which can promote rapid cell proliferation by regulating energy and nutrient metabolism, is considered to be one hallmark of cancer. It can impact other biological processes through complex metabolite-protein interactions.
