Mechanism of head-to-head MCM double-hexamer formation revealed by cryo-EM
Nature, 2019 In preparation for bidirectional DNA replication, the origin recognition complex (ORC) loads two hexameric MCM helicases to form a head-to-head double hexamer around DNA1,2. The mechanism of MCM double-hexamer formation is debated.

Site-specific MCM sumoylation prevents genome rearrangements by controlling origin-bound MCM.
PLoS Genetics, 2022 Timely completion of eukaryotic genome duplication requires coordinated DNA replication initiation at multiple origins. Replication begins with the loading of the Mini-Chromosome Maintenance (MCM) complex, proceeds by the activation of the Cdc45-MCM-GINS

BMP-2-coated mineral coated microparticles improve bone repair in atrophic non-unions [PDF]
European Cells & Materials, 2017 Atrophic non-unions are a major clinical problem. Mineral coated microparticles (MCM) are electrolyte-coated hydroxyapatite particles that have been shown in vitro to bind growth factors electrostatically and enable a tuneable sustained release.

Bulletin of Chemical Reaction Engineering & Catalysis, 2019 This study focused on the Lewis acidity of Al-MCM-41 prepared from bentonite (Al-MCM-bentonite) as silica and aluminum source simultaneously. This acidity was compared with Al-MCM-41 synthesized from pure chemicals reagents (Al-MCM-standard).
