Recurrent H3F3A and IDH2 mutations have been reported in giant cell tumor of bone (GCTB). However, the reported incidences have varied, and other molecular genetic alterations have not been identified due to the small number of cases analyzed with comprehensive methods. Moreover, the relative sensitivities of Sanger sequencing and next-generation sequencing (NGS) for the detection of H3F3A mutations in DNA extracted from archival formalin-fixed paraffin-embedded (FFPE) for clinical diagnosis have not been assessed...

It is important to optimize imaging parameters in 3D-double inversion recovery (DIR) magnetic resonance imaging (MRI) for detecting cortical micro lesions. However, inadequate parameters markedly raise blurring in 3DDIR MRI. The purpose of this study was to evaluate the relationship between the blurring and refocus flip angle (RFA) in 3D-DIR MRI. White matter attenuated inversion recovery (WAIR) images as a test sample were obtained by 1.5T MRI with various RFA settings (30°, 40°, 60°, 100°, 140°, 180°, and variable refocus flip angle (VRFA))...

Bullous pemphigoid (BP) is an autoimmune blistering skin disorder. Recently, BP induced by dipeptidyl peptidase-4 (DPP-4) inhibitors has been a concern. Although DPP-4 inhibitors are commonly used in the Asian population due to their safety and efficacy, BP associated with DPP-4 inhibitors is sometimes seen in clinical settings. Here we report five Japanese cases of BP associated with the agents. In our cases, BP occurred in the elderly by 4 different DPP-4 inhibitors, which showed various clinical manifestations in terms of latency period for BP, sex, glycemic control, and diabetes duration...

A key to the successful use of targeted cancer therapy is the ability to preselect patients who are likely to benefit from the treatment according to molecular markers. Assessment for predicting therapy response is mostly done using tumor biopsies. However, these might not truly represent all of the patient's malignant cells because of tumor heterogeneity and/or clonal evolution during disease progression. One potential strategy that can complement primary tumor biopsy is the analysis of circulating tumor cells (CTCs)...

AIMS: We previously reported that apple polyphenols (AP) and their major active components, procyanidins, had beneficial effects on glucose homeostasis and diabetes in diabetic ob/ob mice. The present study was performed to evaluate the effects of chronic AP administration on glucose tolerance in high-normal and borderline human subjects. METHODS: Subjects (n=65) with a fasting plasma glucose (FPG) level of 100-125mg/dL determined during a recent health check-up were randomised to receive tablets containing AP (600mg/day) or placebo tablets for 12weeks in a double-blinded, placebo-controlled clinical trial...

BACKGROUND: Proprotein convertase subtilisin/kexin type 9 (PCSK9), an important contributor to low-density lipoprotein metabolism in heterozygous familial hypercholesterolemia (HeFH), exhibits direct proatherogenic effects. PCSK9 circulates as mature and furin-cleaved forms, which differ in its biological activity. However, it remains to be elucidated whether each PCSK9 subtype has different atherogenic properties. OBJECTIVE: To investigate the association of each PCSK9 subtype with coronary atherosclerosis in HeFH...

Xanthohumol, a prominent prenyl flavonoid from the hop plant (Humulus lupulus L.), is suggested to be antiatherogenic since it reportedly increases high-density lipoprotein (HDL) cholesterol levels. It is not clear whether xanthohumol promotes reverse cholesterol transport (RCT), the most important antiatherogenic property of HDL; therefore, we investigated the effects of xanthohumol on macrophage-to-feces RCT using a hamster model as a CETP-expressing species. In vivo RCT experiments showed that xanthohumol significantly increased fecal appearance of the tracer derived from intraperitoneally injected [(3)H]-cholesterol-labeled macrophages...

AIMS: Approximately 60-70% of high-grade round-cell sarcomas that lack the EWSR1 rearrangement harbour a rearrangement of the CIC gene, most commonly CIC-DUX4. Recent studies have established that CIC-rearranged sarcomas constitute a distinct group characterised by recognisable histology and immunoprofiles, such as positivity for ETV4 and WT1 and negativity for NKX2.2. Although these sarcomas are increasingly diagnosed in practice by fluorescence in situ hybridisation (FISH) with CIC break-apart probes, the optimal modality to diagnose these sarcomas has not been determined...

It is well known that retinoic acid (RA) suppresses adipogenesis, although there are some contradicting reports. In this study, we examined the effect of extracellular glucose on RA-induced suppression of adipogenesis in 3T3L1 cell culture. When the cells were cultured in normal glucose medium (NG), the addition of RA suppressed lipid accumulation. However, when cultured in high glucose medium (HG), addition of RA to the cells enhanced lipid accumulation. These changes were accompanied by parallel alterations in fatty acid synthase (FAS) and sterol regulatory element-binding protein (SREBP)-1 gene expression...

Monoclonal antibodies and other biologic drugs play important roles in the treatment of various hematological malignancies and solid tumors. However, such drugs are intrinsically more expensive to develop than small molecules and their clinical benefits are often accompanied by challenges relating to affordability and access. Patent expiry for 'originator' biologics is providing opportunities for a new generation of biosimilar drugs, potentially capable of relieving pressure on healthcare budgets. This article discusses key characteristics of biosimilars, distinguishes them from generics and noncomparable biologics and outlines the robust regulatory requirements that must be followed to establish biosimilarity with a reference product...

As the patents for many biologic anticancer drugs expire, significant growth in the use of biosimilars is predicted, offering an opportunity to help combat the rising costs of treatment and increase patient access to biologic therapy. Attainment of regulatory approval, involving numerous nonclinical and clinical comparative studies versus each reference product, is only one of several barriers to realize the potential gains offered by biosimilars. It is important to understand the current perceptions and informational needs of different stakeholders if biosimilars are to be accepted and widely used in the clinic...

For a biosimilar to gain regulatory approval, a comprehensive comparability exercise must demonstrate that it is highly similar to its originator biologic, or reference product. Once biosimilarity has been shown, it is possible to approve the biosimilar for additional indications held by the reference product, without clinical trials in these indications. Extrapolation of clinical data is permitted by regulatory agencies as long as it is scientifically justified. CT-P10, a biosimilar of rituximab, was recently approved in Europe for all indications held by its reference product, incorporating both autoimmune diseases and hematological cancers...

BACKGROUND: Buckwheat (BW) is a potentially life-threatening allergen. Usefulness of BW-specific immunoglobulin-E (BW-sIgE) level for diagnosis of BW allergy is controversial, while the skin prick test (SPT) is widely used because of its less invasive procedure and immediate results. However, there are no data comparing usefulness of the SPT and BW-sIgE level. Therefore, our study aimed to clarify efficacy of the SPT for diagnosis of BW allergy. METHODS: This retrospective cross-sectional study evaluated patients who underwent an oral food challenge (OFC) for diagnosis or confirmation of acquired tolerance using 3072 mg of BW protein between July 2006 and April 2014...

ERdj5, composed of an N-terminal J domain followed by six thioredoxin-like domains, is the largest protein disulfide isomerase family member and functions as an ER-localized disulfide reductase that enhances ER-associated degradation (ERAD). Our previous studies indicated that ERdj5 comprises two regions, the N- and C-terminal clusters, separated by a linker loop and with distinct functional roles in ERAD. We here present a new crystal structure of ERdj5 with a largely different cluster arrangement relative to that in the original crystal structure...
