- Summary: The Fracture Liaison Service (FLS) Consensus Meeting endorsed by the International Osteoporosis Foundation (IOF), Asian Federation of Osteoporosis Societies (AFOS), and Asia Pacific Osteoporosis Foundation (APOF) was hosted by the Taiwanese Osteoporosis Association on October 14, 2017. International and domestic experts reviewed the 13 Best Practice Framework (BPF) standards and concluded that all standards were generally applicable in the Asia-Pacific region and needed only minor modifications to fit the healthcare settings in the region. Purpose: To review and generate consensus on best practices of fracture liaison service (FLS) in the Asia-Pacific (AP) region. Methods: In October 2017, the Taiwanese Osteoporosis Association (TOA) invited experts from the AP region (n = 23), the Capture the Fracture Steering Committee (n = 2), and the USA (n = 1) to join the AP region FLS Consensus Meeting in Taipei. After two rounds of consensus generation, the recommendations on the 13 Best Practice Framework (BPF) standards were reported and reviewed by the attendees. Experts unable to attend the on-site meeting reviewed the draft, made suggestions, and approved the final version. Results: Because the number of FLSs in the region is rapidly increasing, experts agreed that it was timely to establish consensus on benchmark quality standards for FLSs in the region. They also agreed that the 13 BPF standards and the 3 levels of standards were generally applicable, but that some clarifications were necessary. They suggested, for example, that patient and family education be incorporated into the current standards and that communication with the public to promote FLSs be increased. Conclusions: The consensus on the 13 BPF standards reviewed in this meeting was that they were generally applicable and required only a few advanced clarifications to increase the quality of FLSs in the region.

- Importin4 transports histone H3/H4 in complex with Asf1a to the nucleus for chromatin assembly. Importin4 recognizes the nuclear localization sequence located at the N-terminal tail of histones. Here, we analyzed the structures and interactions of human Importin4, histones and Asf1a by cross-linking mass spectrometry, X-ray crystallography, negative-stain electron microscopy, small-angle X-ray scattering and integrative modeling. The cross-linking mass spectrometry data showed that the C-terminal region of Importin4 was extensively cross-linked with the histone H3 tail. We determined the crystal structure of the C-terminal region of Importin4 bound to the histone H3 peptide, thus revealing that the acidic patch in Importin4 accommodates the histone H3 tail, and that histone H3 Lys14 contributes to the interaction with Importin4. In addition, we show that Asf1a modulates the binding of histone H3/H4 to Importin4. Furthermore, the molecular architecture of the Importin4_histone H3/H4_Asf1a complex was produced through an integrative modeling approach. Overall, this work provides structural insights into how Importin4 recognizes histones and their chaperone complex.
