Tumor-induced osteomalacia is characterized by hypophosphatemia and fragility fractures caused by fibroblast growth factor 23 (FGF23)-producing tumors. We report a case of tumor-induced osteomalacia in which the tumor location could be determined by gallium 68 (Ga)-DOTATOC positron emission tomography (PET)/computed tomography (CT). A 74-year-old woman had recurrent fractures and bone pain.

Division of Environmental Medicine and Population Sciences, Department of Social and Environmental Medicine Graduate School of Medicine, Osaka University Suita Japan.

Aim: Timely use of automated external defibrillators by lay rescuers significantly improves the chances of survival in out-of-hospital cardiac arrest cases. We aimed to identify the factors influencing whether lay rescuers bring automated external defibrillators to the scene of nontraumatic out-of-hospital cardiac arrests in schoolchildren in Japan.

Methods: Data on out-of-hospital cardiac arrests among schoolchildren from April 2008 to December 2021 were obtained from the database of the Stop and Prevent cardIac aRrest, Injury, and Trauma in Schools study.

Background: Signaling pathways centered on the G-protein ADP-ribosylation factor 6 (Arf6) and its downstream effector ArfGAP with the SH3 Domain, Ankyrin Repeat and PH Domain 1 (AMAP1) drive cancer invasion, metastasis, and therapy resistance. The Arf6-AMAP1 pathway has been reported to promote receptor recycling leading to programmed cell death-ligand 1 (PD-L1) overexpression in pancreatic ductal carcinoma. Moreover, AMAP1 regulates of nuclear factor-kappa B (NF-κB), which is an important molecule in inflammation and immune activation, including tumor immune interaction through PD-L1 regulation.

Spider silk, especially dragline silk from golden silk spiders (Trichonephila clavipes), is an excellent natural material with remarkable mechanical properties. Many studies have focused on the use of plants as biofactories for the production of recombinant spider silk. However, the effects of this material on the mechanical properties or physiology of transgenic plants remain poorly understood.

Current Landscape of Adoptive Cell Therapy and Challenge to Develop "Off-The-Shelf" Therapy for Hepatocellular Carcinoma.

J Gastroenterol Hepatol

January 2025

Laboratory of Cancer Immunotherapy and Immunology, Transborder Medical Research Center, Faculty of Medicine, University of Tsukuba, Tsukuba, Ibaraki, Japan.

Adoptive cell therapy (ACT) is a type of immunotherapy in which autologous or allogeneic immune cells, such as tumor-infiltrating lymphocytes or engineered lymphocytes, are infused into patients with cancer to eliminate malignant cells. Recently, autologous T cells modified to express a chimeric antigen receptor (CAR) targeting CD19 showed a positive response in clinical studies for hematologic malignancies and have begun to be used in clinical practice. This article discusses the current status and promise of ACT research in hepatocellular carcinoma (HCC), focusing on challenges in off-the-shelf ACT using primary cells or induced pluripotent stem cells (iPSCs) with or without genetic engineering.

The architectural characteristics of metal-organic frameworks (MOFs) can be examined through their net topology, which consists of nodes and linkers. A node's connectivity and site symmetry are likely the key elements influencing the net topology of MOFs. Metal-organic polyhedra (MOPs) function effectively as nodes when used as supermolecular building blocks (SBBs).

Chronic inflammation in the tumour microenvironment (TME) via Th2-polarisation promotes melanoma progression and metastasis, making it a target for immunotherapy. Interleukin (IL)-4 is considered essential for Th2-polarisation in the TME; however, its source remains unknown. Basophils have been postulated as one of its sources.

Individuals diagnosed with Castleman disease (CD) and TAFRO syndrome (characterized by thrombocytopenia, anasarca, fever, bone marrow fibrosis, and organomegaly) displays a wide range of clinical symptoms, including varying patterns of lymph node enlargement, systemic inflammation, and impaired organ function. Some patients may present with both CD and TAFRO syndrome concurrently. A retrospective study conducted across multiple centers in Japan examined 321 cases to determine if the quantity and position of swollen lymph nodes could forecast the clinical progression and intensity of these conditions.

Background: Fatal arrhythmic events (FAEs), such as sudden cardiac death (SCD) and fatal ventricular arrhythmias, are a devastating complication in patients with coronary artery disease (CAD). Therefore, in this study we aimed to assess the incidence of FAEs in more recent Japanese patients with CAD and to examine whether risk stratification of FAEs can still be feasible using the left ventricular ejection fraction (LVEF).

Methods And Results: In the CREDO Kyoto PCI/CABG registry cohorts-2 and -3, there were 25,843 patients with LVEF data who received a first coronary revascularization (LVEF ≤35% group: N=1,671, 35%45%: N=21,503).

Objective: Anemia is a common complication associated with adverse outcomes in older patients undergoing hemodialysis (HD). They also tend to experience malnutrition, which can affect the course of anemia. We hypothesized that the optimal hemoglobin (Hb) level varies depending on nutritional status in older patients undergoing HD and aimed to investigate the association between Hb levels and mortality according to nutritional status.

Menstrual pain affects women's quality of life and productivity, yet objective molecular markers for its severity have not been established owing to the variability in blood levels and chemical properties of potential markers such as plasma steroid hormones, lipid mediators, and hydrophilic metabolites. To address this, we conducted a metabolomics study using five analytical methods to identify biomarkers that differentiate menstrual pain severity. This study included 20 women, divided into mild (N = 12) and severe (N = 8) pain groups based on their numerical pain rating scale.

Validation of Machine Learning-assisted Screening of PKC Ligands: PKC Binding Affinity and Activation.

Biosci Biotechnol Biochem

January 2025

Division of Food Science and Biotechnology, Graduate School of Agriculture, Kyoto University, Kyoto, 606-8502, Japan.

Protein kinase C (PKC) is a family of serine/threonine kinases, and PKC ligands have the potential to be therapeutic seeds for cancer, Alzheimer's disease, and human immunodeficiency virus infection. However, in addition to desired therapeutic effects, most PKC ligands also exhibit undesirable pro-inflammatory effects. The discovery of new scaffolds for PKC ligands is important for developing less inflammatory PKC ligands, such as bryostatins.

Collective cell migration is a fundamental process underlying various biological phenomena, including embryonic development and cancer cell invasion. The cohesive yet flexible movement of cell collectives largely depends on the coordinated regulation of cell-cell and cell-substrate adhesions. In this review, we summarize the regulation of key cell-cell junction components, such as cadherins and zonula occludens proteins during collective cell migration, with a particular focus on the recently discovered multifaceted roles of ZO-1 in both cell-cell and cell-substrate interactions.

Therapeutic drug development for central nervous system injuries, such as traumatic brain injury (TBI), presents significant challenges. TBI results in primary mechanical damage followed by secondary injury, leading to cognitive dysfunction and memory loss. Our recent study demonstrated the potential of carbon monoxide-releasing molecules (CORMs) to improve TBI recovery by enhancing neurogenesis.

During vegetative growth, plants undergo various morphological and physiological changes in the transition from the juvenile phase to the adult phase. In terms of stress resistance, it has been suggested that plants gain or reinforce disease resistance during the process of maturation, which is recognized as adult plant resistance or age-related resistance. While much knowledge has been obtained about changes in disease resistance as growth stages progress, knowledge about changes in plant responses to pathogens with progressing age in plants is limited.

Obesity strongly increases the risk of cardiometabolic diseases, yet the underlying mediators of this relationship are not fully understood. Given that obesity strongly influences circulating protein levels, we investigated proteins mediating the effects of obesity on coronary artery disease, stroke and type 2 diabetes. By integrating two-step proteome-wide Mendelian randomization, colocalization, epigenomics and single-cell RNA sequencing, we identified five mediators and prioritized collagen type VI α3 (COL6A3).
