Identification of 4,5,6,7-Tetrabromo-1H-benzotriazole (TBB) as a Small Molecule MESH1 Inhibitor that Suppresses Ferroptosis

This study identifies 4,5,6,7-tetrabromo-1H-benzotriazole (TBB) as a specific small-molecule inhibitor of the NADPH phosphatase MESH1 that effectively suppresses ferroptosis in vitro and reduces neuronal death in an Alzheimer's disease model, validating MESH1 as a promising therapeutic target.

A sequence-encoded promoter proximal super pause stabilizes an offline RNA polymerase II state

By developing the GATO-seq assay and utilizing cryo-EM, this study reveals that a specific nucleic acid sequence induces a unique, TFIIIS-resistant "super pause" in RNA polymerase II, which stabilizes a reversible, single-nucleotide backtracked "sidetracked" state through a threonine-lined pocket, thereby demonstrating how sequence directly encodes transcriptional pausing control.

A bipartite mechanism for condensin II activation in mitosis

This study reveals that condensin II activation during mitosis operates via a bipartite mechanism where the protein M18BP1 both relieves autoinhibition by the NCAPD3 tail and directly enhances DNA anchoring through a positively charged loop, thereby enabling stable chromosome organization.
