A Crucial Role of Bone Morphogenetic Protein Signaling in the Wound Healing Response in Acute Liver Injury Induced by Carbon Tetrachloride

Background. Acute liver injury induced by administration of carbon tetrachloride (CCl4) has used a model of wound repair in the rat liver. Previously, we reported transient expression of bone morphogenetic protein (Bmp) 2 or Bmp4 at 6–24 h after CCl4 treatment, suggesting a role of BMP signaling in the wound healing response in the injured liver. In the present study, we investigated the biological meaning of the transient Bmp expression in liver injury. Methods. Using conditional knockout mice carrying a floxed exon in the BMP receptor 1A gene, we determined the hepatic gene expressions and proliferative activity following CCl4-treated liver. Results. We observed retardation of the healing response in the knockout mice treated with CCl4, including aggravated histological feature and reduced expressions of the albumin and Tdo2 genes, and a particular decrease in the proliferative activity shown by Ki-67 immunohistochemistry. Conclusion. Our findings suggest a crucial role of BMP signaling in the amelioration of acute liver injury

SORL1 Is Genetically Associated with Late-Onset Alzheimer’s Disease in Japanese, Koreans and Caucasians

To discover susceptibility genes of late-onset Alzheimer’s disease (LOAD), we conducted a 3-stage genome-wide association study (GWAS) using three populations: Japanese from the Japanese Genetic Consortium for Alzheimer Disease (JGSCAD), Koreans, and Caucasians from the Alzheimer Disease Genetic Consortium (ADGC). In Stage 1, we evaluated data for 5,877,918 genotyped and imputed SNPs in Japanese cases (n = 1,008) and controls (n = 1,016). Genome-wide significance was observed with 12 SNPs in the APOE region. Seven SNPs from other distinct regions with p-values ,261025 were genotyped in a second Japanese sample (885 cases, 985 controls), and evidence of association was confirmed for one SORL1 SNP (rs3781834, P=7.3361027 in the combined sample). Subsequent analysis combining results for several SORL1 SNPs in the Japanese, Korean (339 cases, 1,129 controls) and Caucasians (11,840 AD cases, 10,931 controls) revealed genome wide significance with rs11218343 (P=1.7761029) and rs3781834 (P=1.0461028). SNPs in previously established AD loci in Caucasians showed strong evidence of association in Japanese including rs3851179 near PICALM (P=1.7161025) and rs744373 near BIN1 (P = 1.3961024). The associated allele for each of these SNPs was the same as in Caucasians. These data demonstrate for the first time genome-wide significance of LOAD with SORL1 and confirm the role of other known loci for LOAD in Japanese. Our study highlights the importance of examining associations in multiple ethnic populations

Development and validation of clinical implementation methods for patient-reported outcomes in Japanese multi-center palliative care units

Abstract Background Patient-Reported Outcomes (PROs) are recommended for use in clinical oncology. However, they are not routinely used in professional palliative care practices in Japan. The reasons include both patient and healthcare provider factors and the implementation of PROs. This study aimed to develop and validate clinical implementation methods for PROs in Japanese palliative care units. Methods The Consolidated Framework for Implementation Research (CFIR) was conducted with four palliative care units in Japan. The study was conducted in six steps: unit assessment, development and implementation of a PRO implementation plan, PRO post-implementation survey and analysis of its utilization, a review of the PRO implementation process, creation of a PRO implementation method in a palliative care unit, and use and verification of the implementation method. Steps 1–5 were the development phase, and step 6 was the verification phase. Results Interviews were conducted with healthcare providers prior to PRO implementation. Intervention characteristics, patient needs in the palliative care unit, and factors related to the organization were identified as barriers. The implementation plan was developed, and the core members were selected. The implementation procedures were created in the above mentioned steps. PROs were used in the palliative care units. The same was true in the validation phase. Conclusions This study guided PROs in specialized palliative care unit in a clinical setting. The method was developed and validated for the implementation of PROs in the palliative care unit. In the PRO implementation process, it was important to assess the unit, address the barriers to implementation, and reduce the burden on healthcare providers. Furthermore, healthcare providers had to be supported by the champion, a person responsible for the implementation of PROs in the palliative care unit
