A study published in Science Bulletin identifies tRF-Glu-TTC-013, a tRNA-derived fragment, as a key driver of colorectal cancer liver metastasis. The researchers found that the molecule promotes tumour progression by enhancing glutamate metabolic reprogramming through a newly defined CREB3L1–AMDHD1 pathway.
Researchers created a bismuth-coordinated melanin material that provides in vivo physical radiation shielding and ROS scavenging. It markedly mitigates acute radiation syndrome and boosts mouse survival from 20% to 60% after lethal total body irradiation.
Acute-on-chronic liver failure (ACLF) has been recognized for almost 30 years, but there is still no unified definition or diagnostic standard worldwide. Recently, the core clinical features used to describe ACLF have narrowed these differences and built a broader consensus. This review updates the latest changes in disease classification, summarizes the current understanding of ACLF pathogenesis, outlines new treatment targets, and presents a three-stage mouse model that supports testing of potential therapies.
