Abstract
Cell separation using microfluidics has become an effective method to isolate biological contaminants from bodily fluids and cell cultures, such as isolating bacteria contaminants from microalgae cultures and isolating bacteria contaminants from white blood cells. In this study, bacterial cells were used as a model contaminant in microalgae culture in a passive microfluidics device, which relies on hydrodynamic forces to demonstrate the separation of microalgae from bacteria contaminants in U and W-shaped cross-section spiral microchannel fabricated by defocusing CO2 laser ablation. At a flow rate of 0.7 ml/min in the presence of glycine as bacteria chemoattractant, the spiral microfluidics devices with U and W-shaped cross-sections were able to isolate microalgae (Desmodesmus sp.) from bacteria (E. coli) with a high separation efficiency of 92% and 96% respectively. At the same flow rate, in the absence of glycine, the separation efficiency of microalgae for U- and W-shaped cross-sections was 91% and 96%, respectively. It was found that the spiral microchannel device with a W-shaped cross-section with a barrier in the center of the channel showed significantly higher separation efficiency. Spiral microchannel chips with U- or W-shaped cross-sections were easy to fabricate and exhibited high throughput. With these advantages, these devices could be widely applicable to other cell separation applications, such as separating circulating tumor cells from blood.

Abstract
Thymus medulla epithelium establishes immune self-tolerance and comprises diverse cellular subsets. Functionally relevant medullary thymic epithelial cells (mTECs) include a self-antigen-displaying subset that exhibits genome-wide promiscuous gene expression promoted by the nuclear protein Aire and that resembles a mosaic of extrathymic cells including mucosal tuft cells. An additional mTEC subset produces the chemokine CCL21, thereby attracting positively selected thymocytes from the cortex to the medulla. Both self-antigen-displaying and thymocyte-attracting mTEC subsets are essential for self-tolerance. Here, we identify a developmental pathway by which mTECs gain their diversity in functionally distinct subsets. We show that CCL21-expressing mTECs arise early during thymus ontogeny in mice. Fate-mapping analysis reveals that self-antigen-displaying mTECs, including Aire-expressing mTECs and thymic tuft cells, are derived from CCL21-expressing cells. The differentiation capability of CCL21-expressing embryonic mTECs is verified in reaggregate thymus experiments. These results indicate that CCL21-expressing embryonic mTECs carry a developmental potential to give rise to self-antigen-displaying mTECs, revealing that the sequential conversion of thymocyte-attracting subset into self-antigen-displaying subset serves to assemble functional diversity in the thymus medulla epithelium.

Abstract
BACKGROUND AND OBJECTIVE This study examined the relationship between body mass index (BMI) and sarcopenia with oral function decline in older patients as well as whether a combination of underweight BMI and sarcopenia was associated with decreased oral function in individuals with conservative restorative and prosthetic treatment for masticatory disorders. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study included 290 older Japanese patients who regularly attended a general dental clinic. A detailed examination of oral function, sarcopenia, and BMI according to the Asian Working Group for Sarcopenia 2019 criteria was conducted for patients aged 65 years. This study used odds ratios as an epidemiological measure in the cross-sectional survey. RESULTS Multinomial logistic regression analysis showed that the number of remaining teeth and tongue pressure was associated with both ideal and overweight BMI in individuals with sarcopenia when compared to healthy individuals. The underweight BMI plus sarcopenia group was associated with tongue and lip motor function [ka] sound test, swallowing function, and the presence of oral hypofunction. DISCUSSION Our findings indicated that various aspects of oral function were impaired in community-dwelling older adult Japanese patients with sarcopenia and underweight BMI. Notably, among older adults with sarcopenia, both obese and thin patients exist, suggesting that distinct pathophysiological mechanisms influence oral function. CONCLUSION The above findings support the hypothesis that the coexistence of sarcopenia and underweight BMI is associated with poor oral function. Regular oral function assessments and weight measurements in general dental practice can aid the prompt identification of sarcopenia and reduced swallowing function and can facilitate early intervention. The presence of sarcopenia and impaired swallowing function should be considered in patients with underweight BMI, reduced [ka] sound, and low tongue pressure following a thorough oral function examination.

Abstract
Plant viruses induce various disease symptoms that substantially impact agriculture, but the underlying mechanisms of viral disease in plants are poorly understood. Kobu-sho is a disease in gentian that shows gall formation with ectopic development of lignified cells and vascular tissues such as xylem. Here, we show that a gene fragment of gentian Kobu-sho-associated virus, which is designated as Kobu-sho-inducing factor (KOBU), induces gall formation accompanied by ectopic development of lignified cells and xylem-like tissue in Nicotiana benthamiana. Transgenic gentian expressing KOBU exhibited tumorous symptoms, confirming the gall-forming activity of KOBU. Surprisingly, KOBU expression can also induce differentiation of an additional leaf-like tissue on the abaxial side of veins in normal N. benthamiana and gentian leaves. Transcriptome analysis with Arabidopsis thaliana expressing KOBU revealed that KOBU activates signaling pathways that regulate xylem development. KOBU protein forms granules and plate-like structures and co-localizes with mRNA splicing factors within the nucleus. Our findings suggest that KOBU is a novel pleiotropic virulence factor that stimulates vascular and leaf development. IMPORTANCE While various mechanisms determine disease symptoms in plants depending on virus-host combinations, the details of how plant viruses induce symptoms remain largely unknown in most plant species. Kobu-sho is a disease in gentian that shows gall formation with ectopic development of lignified cells and vascular tissues such as xylem. Our findings demonstrate that a gene fragment of gentian Kobu-sho-associated virus (GKaV), which is designated as Kobu-sho-inducing factor, induces the gall formation accompanied by the ectopic development of lignified cells and xylem-like tissue in Nicotiana benthamiana. The molecular mechanism by which gentian Kobu-sho-associated virus induces the Kobu-sho symptoms will provide new insight into not only plant-virus interactions but also the regulatory mechanisms underlying vascular and leaf development.

Abstract
Grapevine crown gall (GCG) is a significant bacterial disease caused by tumorigenic Allorhizobium vitis (TAV) and is prevalent worldwide. TAV infects grapevines through wounds such as freezing injuries. Although grapevines typically avoid being wounded under snow cover, GCG occurs in many commercial vineyards in snowy regions. This study investigated the TAV population in GCG gall tissues, grapevine skins, and snow on grapevine skins from six infected vineyards located in Hokkaido, Japan, an area known for heavy snowfall. TAV was isolated not only from gall tissues but also from skins and snow on skins throughout the year. Hierarchical Bayesian model (HBM) analysis revealed that the number of TAV cells in gall tissues was affected by cultivar and low temperature, while those in skins were affected by location and low temperature. Additionally, Bayesian changepoint detection (BCD) showed that the number of TAV cells in gall and skin tissues increased during winter, including the snowfall season. Furthermore, the TAV population in grapevine skins under the snow was significantly higher than those above the snow, indicating that TAV under the snow is protected by the snow and can survive well during the snowfall season. This study highlights the ability of TAV to overwinter on/in galls and skins under the snow and act as inoculum for the next season.

Abstract
The conformation and alignment of molecules in organic materials are important because they affect the materials' bulk physical properties. Because two-dimensional (2D) materials offer a simpler model of three-dimensional (3D) materials, the conformation and alignment of molecules in 2D assemblies have been investigated at the atomic scale by scanning tunnelling microscopy (STM). However, differences in the conformation and alignment of molecules between 2D and 3D assemblies have not been clarified. In this work, the conformation and alignment of a donor-acceptor-type molecule, 4-(3,3-dimethyl-2,3-dihydro-1H-indol-1-yl)benzonitrile (IBN), are studied in 2D and 3D assemblies. Thus, the 2D assembly of IBN on the Au(111) surface was investigated by STM and the 3D assembly of IBN in a single crystal was investigated by X-ray crystallography. Our survey revealed that the conformation of IBN is planar in both 2D and 3D assemblies because of the electron-delocalised structure resulting from the electron-donating and electron-accepting groups of IBN; thus, the values of the dipole moment of IBN in 2D and 3D assemblies are essentially the same. In both the 2D and 3D assemblies, IBN molecules align to cancel out the dipole moment even though the self-assembled structures differ. In the 2D assemblies, the orientation and self-assembled structure of IBN are changed by the surface density of IBN, and they are affected by the crystal orientation and superstructure of Au(111) because of the strong interaction between IBN and Au(111). In addition, scanning tunnelling spectroscopy revealed that the coordination structure is not included in the self-assembled structure of IBN on Au(111).

Abstract
CREB/ATF transcription factor OASIS/CREB3L1 is upregulated in long-term-cultured astrocytes undergoing cell-cycle arrest due to loss of DNA integrity by repeated replication. However, the roles of OASIS in the cell cycle remain unexplored. We find that OASIS arrests the cell cycle at G2/M phase after DNA damage via direct induction of p21. Cell-cycle arrest by OASIS is dominant in astrocytes and osteoblasts, but not in fibroblasts, which are dependent on p53. In a brain injury model, Oasis-/- reactive astrocytes surrounding the lesion core show sustained growth and inhibition of cell-cycle arrest, resulting in prolonged gliosis. We find that some glioma patients exhibit low expression of OASIS due to high methylation of its promoter. Specific removal of this hypermethylation in glioblastomas transplanted into nude mice by epigenomic engineering suppresses the tumorigenesis. These findings suggest OASIS as a critical cell-cycle inhibitor with potential to act as a tumor suppressor.

Abstract
Ethylene response factors (ERFs) comprise one of the largest transcription factor families in many plant species. Tobacco (Nicotiana tabacum) ERF3 (NtERF3) and other ERF-associated amphiphilic repression (EAR) motif-containing ERFs are known to function as transcriptional repressors. NtERF3 and several repressor-type ERFs induce cell death in tobacco leaves and are also associated with a defence response against tobacco mosaic virus (TMV). We investigated whether transcriptional activator-type NtERFs function together with NtERF3 in the defence response against TMV infection by performing transient ectopic expression, together with gene expression, chromatin immunoprecipitation (ChIP) and promoter analyses. Transient overexpression of NtERF2 and NtERF4 induced cell death in tobacco leaves, albeit later than that induced by NtERF3. Fusion of the EAR motif to the C-terminal end of NtERF2 and NtERF4 abolished their cell death-inducing ability. The expression of NtERF2 and NtERF4 was upregulated at the early phase of N gene-triggered hypersensitive response (HR) against TMV infection. The cell death phenotype induced by overexpression of wild-type NtERF2 and NtERF4 was suppressed by co-expression of an EAR motif-deficient form of NtERF3. Furthermore, ChIP and promoter analyses suggested that NtERF2, NtERF3 and NtERF4 positively or negatively regulate the expression of NtERF3 by binding to its promoter region. Overall, our results revealed the cell death-inducing abilities of genes encoding activator-type NtERFs, including NtERF2 and NtERF4, suggesting that the HR-cell death signalling via the repressor-type NtERF3 is competitively but coordinately regulated by these NtERFs.

Abstract
It is known that p53 is an important transcription factor and plays a central role in ionizing radiation (IR)-induced DNA damage responses such as cell cycle arrest, DNA repair and apoptosis. We previously reported that regulating p53 protein is an effective strategy for modulating cell fate by reducing the acute side effects of radiation therapy. Herein, we report on the discovery of STK160830 as a new radioprotector from a chemical library at The University of Tokyo and the design, synthesis and biological evaluation of its derivatives. The radioprotective activity of STK160830 itself and its derivatives that were synthesized in this work was evaluated using a leukemia cell line, MOLT-4 cells as a model of normal cells that express the p53 protein in a structure-activity relationships (SAR) study. The experimental results suggest that a direct relationship exists between the inhibitory effect of these STK160830 derivatives on the expression level of p53 and their radioprotective activity and that the suppression of p53 by STK160830 derivatives contribute to protecting MOLT-4 cells from apoptosis that is induced by exposure to radiation.

Abstract
In the thymus, the thymic epithelium provides a microenvironment essential for the development of functionally competent and self-tolerant T cells. Previous findings showed that modulation of Wnt/β-catenin signaling in mouse thymic epithelial cells (TECs) disrupts embryonic thymus organogenesis. However, the role of β-catenin in TECs for postnatal T-cell development remains to be elucidated. Here, we analyzed gain-of-function (GOF) and loss-of-function (LOF) of β-catenin highly specific in mouse TECs. We found that GOF of β-catenin in TECs results in severe thymic dysplasia and T-cell deficiency beginning from the embryonic period. By contrast, LOF of β-catenin in TECs reduces the number of cortical TECs and thymocytes modestly and only postnatally. These results indicate that fine-tuning of β-catenin expression within a permissive range is required for TECs to generate an optimal microenvironment to support postnatal T-cell development.

Abstract
Crown gall is a globally distributed and economically important disease of grapevine and other important crop plants. The causal agent of grapevine crown gall is tumorigenic Allorhizobium vitis (Ti) strains that harbor a tumor-inducing plasmid (pTi). The epidemic of grapevine crown gall has not been widely elucidated. In this study, we investigated the genetic diversity of 89 strains of Ti and nonpathogenic A. vitis to clarify their molecular epidemiology. Multi-locus sequence analysis (MLSA) of the partial nucleotide sequences of pyrG, recA, and rpoD was performed for molecular typing of A. vitis strains isolated from grapevines with crown gall symptoms grown in 30 different vineyards, five different countries, mainly in Japan, and seven genomic groups A to F were obtained. The results of MLSA and logistic regression indicated that the population of genetic group A was significantly related to a range of prefectures and that the epidemic of group A strains originated mainly in Hokkaido in Japan through soil infection. Moreover, group E strains could have been transported by infected nursery stocks. In conclusion, this study indicates that both soil infection and transporting of infected nursery stocks are working as infection source in Hokkaido.

Abstract
RNA synthesis inhibitors and protein synthesis inhibitors are useful for investigating whether biological events with unknown mechanisms require transcription or translation; however, the dependence of RNA synthesis has been difficult to verify because many RNA synthesis inhibitors cause adverse events that trigger a p53 response. In this study, we screened a library containing 9600 core compounds and obtained STK160830 that shows anti-apoptotic effects in irradiated wild-type-p53-bearing human T-cell leukemia MOLT-4 cells and murine thymocytes. In many of the p53-impaired cells and p53-knockdown cells tested, STK160830 did not show a remarkable anti-apoptotic effect, suggesting that the anti-apoptotic activity is p53-dependent. In the expression analysis of p53, p53-target gene products, and reference proteins by immunoblotting, STK160830 down-regulated the expression of many of the proteins examined, and the downregulation correlated strongly with its inhibitory effect on cell death. mRNA expression analyses by qPCR and nascent RNA capture kit revealed that STK160830 showed a decreased mRNA expression, which was similar to that induced by the RNA synthesis inhibitor actinomycin D but differed to some extent. Furthermore, unlike other RNA synthesis inhibitors such as actinomycin D, p53 accumulation by STK160830 alone was negligible, and a DNA melting-curve analysis showed very weak DNA-intercalating activity, indicating that STK160830 is a useful inhibitor for RNA synthesis without triggering p53-mediated damage responses.

Abstract
Ranunculus (Ranunculus asiaticus L.) is one of the most popular cut flowers in Japan. However, the infection rate of ranunculus mild mosaic virus (RanMMV) in ranunculus plants has been gradually increasing during cultivation, suggesting that RanMMV may be transmitted from weeds to ranunculus plants in cultivation fields. In our survey, RanMMV in R. japonicus, R. tachiroei, R. cantoniensis, Geranium carolinianum, Vicia sativa, V. tetrasperma and V. hirsute in ranunculus fields and noncultivation regions in Japan was detected. Ranunculaceae weeds grow all year in cultivation fields, unlike R. asiaticus, indicating that these weeds may be a source of RanMMV infection. In addition, a pairwise comparison of CP genes between RanMMV isolates taken from R. asiaticus, R. japonicus, and R. tachiroei showed high nucleotide (98·1-100%) and amino acid (98·5-100%) identities. These results support the hypothesis that RanMMV may be transmitted between Ranunculaceae weeds and R. asiaticus plants. Thus, virus control should focus on removing host weeds from the cultivation fields.

Abstract
Previous studies reported the critical role of the brefeldin A-inhibited guanine nucleotide exchange protein 3-prohibitin 2 (BIG3-PHB2) complex in modulating estrogen signaling activation in breast cancer cells, yet its pathophysiological roles in osteosarcoma (OS) cells remain elusive. Here, we report a novel function of BIG3-PHB2 in OS malignancy. BIG3-PHB2 complexes were localized mainly in mitochondria in OS cells, unlike in estrogen-dependent breast cancer cells. Depletion of endogenous BIG3 expression by small interfering RNA (siRNA) treatment led to significant inhibition of OS cell growth. Disruption of BIG3-PHB2 complex formation by treatment with specific peptide inhibitor also resulted in significant dose-dependent suppression of OS cell growth, migration, and invasion resulting from G2/M-phase arrest and in PARP cleavage, ultimately leading to PARP-1/apoptosis-inducing factor (AIF) pathway activation-dependent apoptosis in OS cells. Subsequent proteomic and bioinformatic pathway analyses revealed that disruption of the BIG3-PHB2 complex might lead to downregulation of inner mitochondrial membrane protein complex activity. Our findings indicate that the mitochondrial BIG3-PHB2 complex might regulate PARP-1/AIF pathway-dependent apoptosis during OS cell proliferation and progression and that disruption of this complex may be a promising therapeutic strategy for OS.

Abstract
Derlin family members (Derlins) are primarily known as components of the endoplasmic reticulum-associated degradation pathway that eliminates misfolded proteins. Here we report a function of Derlins in the brain development. Deletion of Derlin-1 or Derlin-2 in the central nervous system of mice impaired postnatal brain development, particularly of the cerebellum and striatum, and induced motor control deficits. Derlin-1 or Derlin-2 deficiency reduced neurite outgrowth in vitro and in vivo and surprisingly also inhibited sterol regulatory element binding protein 2 (SREBP-2)-mediated brain cholesterol biosynthesis. In addition, reduced neurite outgrowth due to Derlin-1 deficiency was rescued by SREBP-2 pathway activation. Overall, our findings demonstrate that Derlins sustain brain cholesterol biosynthesis, which is essential for appropriate postnatal brain development and function. Derlin-1 and Derlin-2 are essential for postnatal brain development and function Chemical chaperon does not ameliorate the phenotype of Derlin-deficient neuron Derlin regulates SREBP-2 activation and promotes brain cholesterol biosynthesis Derlin-mediated cholesterol biosynthesis is essential for neurite outgrowth

Abstract
Potato viral disease has been a major problem in potato production worldwide including Russia. Here, we detected Potato Virus M (PVM), P (PVP), S (PVS), Y (PVY), and X (PVX) and Potato Leaf Roll Virus (PLRV) by RT-PCR on potato leaves and tubers from the Northwestern (NW), Volga (VF), and Far Eastern (FE) federal districts of Russia. Each sample was co-infected with up to five viruses. RT-PCR disclosed all six viruses in NW, three in VF, and five in FE. Phylogenetic analyses of PVM and PVS strains resolved all PVM isolates in Group O (ordinary) and all PVS isolates in Group O. Seven PVY strains were detected, and they included only recombinants. PVY recombinants were thus the dominant potato virus strains in Russia, although they widely varied among the regions. Our research provides insights into the geographical distribution and genetic variability of potato viruses in Russia.

Abstract
The thymic function to produce self-protective and self-tolerant T cells is chiefly mediated by cortical thymic epithelial cells (cTECs) and medullary TECs (mTECs). Recent studies including single-cell transcriptomic analyses have highlighted a rich diversity in functional mTEC subpopulations. Because of their limited cellularity, however, the biochemical characterization of TECs, including the proteomic profiling of cTECs and mTECs, has remained unestablished. Utilizing genetically modified mice that carry enlarged but functional thymuses, here we show a combination of proteomic and transcriptomic profiles for cTECs and mTECs, which identified signature molecules that characterize a developmental and functional contrast between cTECs and mTECs. Our results reveal a highly specific impact of the thymoproteasome on proteasome subunit composition in cTECs and provide an integrated trans-omics platform for further exploration of thymus biology. Ohigashi et al. show that the use of cyclin D1-transgenic mice allows quantitative proteomic analysis of cortical and medullary thymic epithelial cells (TECs). Results provide a trans-omics platform for further exploration of TEC biology and reveal the specific impact of the thymoproteasome on proteasome subunit composition in cortical TECs.

Abstract
Polypeptide N‑acetylgalactosaminyltransferase 6 (GALNT6), which is involved in the initiation of O‑glycosylation, has been reported to play crucial roles in mammary carcinogenesis through binding to several substrates; however, its biological roles in mediating growth‑promoting effects remain unknown. The present study demonstrated a crucial pathophysiological role of GALNT6 through its O‑glycosylation of lectin galactoside‑binding soluble 3 binding protein (LGALS3BP), a secreted growth‑promoting glycoprotein, in breast cancer growth. The Cancer Genome Atlas data analysis revealed that high expression levels of GALNT6 were significantly associated with poor prognosis of breast cancer. GALNT6 O‑glycosylated LGALS3BP in breast cancer cells, whereas knockdown of GALNT6 by siRNA led to the inhibition of both the O‑glycosylation and secretion of LGALS3BP, resulting in the suppression of breast cancer cell growth. Notably, LGALS3BP is potentially O‑glycosylated at three sites (T556, T571 and S582) by GALNT6, thereby promoting autocrine cell growth, whereas the expression of LGALS3BP with three Ala substitutions (T556A, T571A and S582A) in cells drastically reduced GALNT6‑dependent LGALS3BP O‑glycosylation and secretion, resulting in suppression of autocrine growth‑promoting effect. The findings of the present study suggest that the GALNT6‑LGALS3BP axis is crucial for breast cancer cell proliferation and may be a therapeutic target and biomarker for mammary tumors.

Abstract
Analysis of anticancer immunity aids in assessing the prognosis of patients with breast cancer. From 250 operated breast cancers, we focused on serum levels of C‐C motif chemokine ligand 5 (CCL5), which is involved in cancer immune reactions. Serum levels of CCL5 were measured using a cytometric bead‐based immunoassay kit and CCL5 expression in cancer cells was determined using immunohistochemical staining. In addition, mRNA in cancer and stromal cells was analyzed by microdissection and comparison with the public dataset. Disease‐free survival (DFS) of patients with high CCL5 levels (cut‐off, 13.87 ng/mL; n = 192) was significantly better than those with low CCL5 levels (n = 58; hazard ratio, 0.20; 95% confidence interval, 0.10‐0.39; P < .0001). An improved overall survival was observed in patients with high CCL5 levels compared to those with low CCL5 levels (P = .024). On the contrary, high immunohistochemical expression of CCL5 in cancer cells was significantly associated with decreased DFS. As serum CCL5 levels did not correlate with CCL5 expression in cancer cells and the relative expression of mRNA CCL5 was elevated in stromal cells in relation to cancer cells, serum CCL5 might be derived not from cancer cells, but from stromal cells. Expression of CCL5 in serum, but not in cancer cells, might contribute to improved patient prognosis mediating through not only immune reaction, but through other mechanisms. Determination of circulating CCL5 levels could be useful for predicting patient prognosis.

Abstract
BACKGROUND/AIM Interleukin (IL)-18, which belongs to the IL-1 superfamily of cytokines, is a known interferon-gamma (IFN-γ)-inducing factor. Since IFN-γ plays an essential role in anticancer immunity mediated through cytotoxic T cells, IL-18 may also contribute to the function of immunosurveillance. The aim of the study was to examine the association of IL-18 with the outcomes of patients with breast cancer. PATIENTS AND METHODS Serum IL-18 levels were determined at baseline in 270 patients operated for breast cancer, and the relapse-free survival (RFS) was compared between IL-18-high and -low groups. The relationships between IL-18 and tumor-infiltrating lymphocytes (TILs) or the neutrophil-to-lymphocyte ratio (NLR) were also investigated. RESULTS The RFS of patients was significantly better in the IL-18-low group than in the IL-18-high group (p=0.032). According to the multivariate analysis, IL-18 was a significant and independent predictive factor for RFS (hazard ratio(HR)=0.336; 95% confidence interval(CI)=0.147-0.727; p=0.0053). No association was observed between the IL-18 levels and TILs or NLRs. CONCLUSION IL-18 levels may be useful for predicting the prognosis of patients who have received surgical treatment for breast cancer.

Abstract
Contigs with sequence similarity to potato virus P (PVP), which belongs to the genus Carlavirus, were identified by high-throughput sequencing analysis in potato tubers collected from a farmer's potato production field in Surazhevka, Artyom, Primorskiy Krai (Russia) in 2018. The complete genome sequence of this virus consisted of 8,394 nucleotides, excluding the poly(A) tail. This is the first report of PVP being detected outside South America. The isolate had high sequence similarity to PVP isolates from Argentina and Brazil, but low sequence similarity was observed in the genes encoding the RNA-dependent RNA polymerase (69% nucleotide sequence identity and 80% amino acid sequence identity) and coat protein (78% nucleotide sequence identity and 89% amino acid sequence identity). Phylogenetic analysis revealed that this PVP-like virus clustered with known PVP isolates but was distinct from them. Comparison of the sequences using the classification criteria of the ICTV indicated that this PVP-like virus is a strain of PVP.

Abstract
AIMS Alterations in microenvironments are a hallmark of cancer, and these alterations in germinomas are of particular significance. Germinoma, the most common subtype of central nervous system germ cell tumours, often exhibits massive immune cell infiltration intermingled with tumour cells. The role of these immune cells in germinoma, however, remains unknown. METHODS We investigated the cellular constituents of immune microenvironments and their clinical impacts on prognosis in 100 germinoma cases. RESULTS Patients with germinomas lower in tumour cell content (i.e. higher immune cell infiltration) had a significantly longer progression-free survival time than those with higher tumour cell contents (P = 0.03). Transcriptome analyses and RNA in-situ hybridization indicated that infiltrating immune cells comprised a wide variety of cell types, including lymphocytes and myelocyte-lineage cells. High expression of CD4 was significantly associated with good prognosis, whereas elevated nitric oxide synthase 2 was associated with poor prognosis. PD1 (PDCD1) was expressed by immune cells present in most germinomas (93.8%), and PD-L1 (CD274) expression was found in tumour cells in the majority of germinomas examined (73.5%). CONCLUSIONS The collective data strongly suggest that infiltrating immune cells play an important role in predicting treatment response. Further investigation should lead to additional categorization of germinoma to safely reduce treatment intensity depending on tumour/immune cell balance and to develop possible future immunotherapies.

Abstract
Overexpression of the human epidermal growth factor receptor 2 (HER2) in breast cancer is linked to aggressive tumor behavior and a poorer prognosis. Anti-HER2 monoclonal antibody, trastuzumab extends the overall survival of patients with HER2-overexpressing breast cancer, but resistance to trastuzumab and/or other HER2-targeted therapies remains a serious clinical problem. Our previous studies demonstrated that Brefeldin A-Inhibited Guanine nucleotide-exchange protein 3 (BIG3), which is exclusively overexpressed in the majority of breast cancers, functions as a cancer specific A-kinase anchoring protein that binds protein kinase A (PKA) and protein phosphatase 1 (PP1Cα), thereby inactivating prohibitin2 (PHB2) suppressive activity through its dephosphorylation on Ser39. We further developed dominant-negative stapling peptide (stERAP), which is designed to specifically disrupt binding of BIG3-PHB2 complex and improve duration of their anti-tumor effects. Here we newly report that stERAP has significant suppressive effects on the HER2 signaling network by activating the tumor suppressive ability of PHB2. stERAP resulted in intrinsic PHB2 release from BIG3, followed by rapid phosphorylation on Ser39, Thr42 and Thr169 via PKCα, TTK and MK5, respectively. Importantly, PHB2 released from BIG3 by stERAP treatment translocated into nucleus, followed by acting as a transcriptional co-repressor by recruiting HDAC1 and NcoR through its Ser39-phosphorylation. More importantly, we observed that serine/threonine phosphorylations of PHB2 are necessary for disruption of HER2-HER3 hetero-dimerization and NF-κB signalling activation which are associated with acquired resistance to trastuzumab. We demonstrated that weekly treatment of stERAP completely suppressed the proliferation of trastuzumab-resistant HER2-positive breast cancer cells in vitro and in vivo. We are currently examining the association of both BIG3 overexpression and PHB2 dephosphorylation with poor prognosis of patients with HER2-positive breast cancers by immunohistochemical staining, and will report these results at this meeting. We demonstrated for the first time that PHB2 inactivation by the AKAP-BIG3 (BIG3/PKA/PP1Cα tri-complex) is required for oncogenic HER2 signalling activation in breast cancer cells, and stERAP may be a promising anti-cancer drug for trastuzumab-resistant breast cancer.

Abstract
Abstract
Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer and worse disease-specific outcomes compared with other subtypes. Because of the lack of estrogen and progesterone receptors and HER2 gene amplification, cytotoxic agents remain the mainstay of treatment for TNBC patients. Although TNBC is enriched for germline and somatic BRCA mutation, a phenotype termed BRCAness, PARP inhibitors as monotherapy failed to improve the outcome of TNBC patients. Therefore, we aimed to uncover molecular characterization in TNBC cases by whole-exome sequencing analysis of genomic DNAs from 36 Japanese patients with TNBC compared with their corresponding normal. We identified 36 genes that were recurrently mutated (>10% of cases) in TNBC cases, including TP53 and PIK3CA as described in the previous next generation sequencing analysis of TNBC cases. Remarkably, we identified a number of epigenetic-related genes involved in histone modification and DNA methylation, which were mutated in 20 out of 36 (55.6%) cases. Among them, we focused on spalt like transcription factor 3 (SALL3) gene which shows recurrent somatic mutations, and are most frequently downregulated in TNBC cases. Ectopic overexpression of the wildtype SALL3, but not the somatically mutated SALL3 into BT549 breast cancer cells, which expresses low level of SALL3 gene, caused the significant suppression of cell growth. Importantly, promoter regions of SALL3 gene was frequently hypermethylated and transcriptionally silenced in only TNBC cases, but not in other types of breast cancer by TCGA data analysis. Moreover, the expression of SALL3 was restored after treatments of 5-aza-2’-deoxycitidine in TNBC cell line, HCC1937. Notably, siRNA-mediated knockdown of SALL3 expression in BT20 cells enhanced chemoresistance against paclitaxel and docetaxel, respectively. Moreover, low expression of SALL3 was associated with significantly shorter relapse free survival. Notably, because SALL3 retains eight C2H2-type zinc finger domains which are extremely conserved in mammalian transcription factors, we hypothesized that SALL3 transcriptionally regulates genes which are involved in progression and chemoresistance of TNBC. We identified the several candidates of SALL3-taget genes by gene expression and chromatin immunoprecipitation analyses. Our findings provide the evidence of a pathophysiological role for SALL3 as a tumor suppressor which is possibly associated with progression and chemoresistance of TNBC.

Abstract
Viroids can be transmitted vertically and/or horizontally by pollen. Tomato planta macho viroid (TPMVd) has a high rate of horizontal transmission by pollen, whereas potato spindle tuber viroid (PSTVd) does not. To specify the domain(s) involved in horizontal transmission, four viroid chimeras were created by exchanging the terminal left (TL) and/or pathogenicity (P) domains between PSTVd and TPMVd. PSTVd-based chimeras containing TPMVd-TL and P, or TPMVd-TL alone, displayed a high rate of horizontal transmission. TPMVd-based chimeras containing PSTVd-TL and P lost infectivity, and those containing PSTVd-TL alone displayed a low rate of horizontal transmission. In addition, the vertical transmission rate was also higher in the mutants containing TPMVd-TL than in the others. These findings indicate that the sequences or structures in the TL and P (although the role is limited) domains are important not only for horizontal but also for vertical transmission by pollen.

Abstract
OBJECTIVES Prothymosin α (ProTα) was reported to inhibit the neuronal necrosis by facilitating the plasma membrane localization of endocytosed glucose transporter 1/4 through an activation of putative Gi-coupled receptor. The present study aims to identify a novel ProTα target, which may lead to an activation of Gi-coupled receptor. METHODS We used Gi-rich lipid rafts fraction of retinal cell line N18-RE-105 cells for affinity cross-linking. The biological confirmation that F0/F1 ATPase is a target protein complex was performed by cell-free experiments using ELISA-based binding assay, surface plasmon resonance assay and quartz crystal microbalance assay, and cell-based experiments to measure extracellular ATP level in the HUVECs culture. RESULTS From the cross-linking study and above-mentioned protein-protein interaction assays, ATP5A1 and ATP5B, F1 ATPase subunits were found to ProTα binding target proteins. In the culture of HUVEC cells, furthermore, ProTα increased the extracellular ATP levels in a reversible manner by anti-ATP5A1- and ATP5B-antibodies. CONCLUSION The present study suggests that ProTα may activate ecto-F0/F1 ATPase and produced ATP. This study leads to next subjects whether produced ATP and its metabolites, ADP or adenosine may activate corresponding Gi-coupled receptors.

Abstract
Abstract
Overexpression of the human epidermal growth factor receptor 2 (HER2) is associated with aggressive tumor behavior and poor prognosis in breast cancer. Although anti-HER2 monoclonal antibody, trastuzumab shows considerable efficacy and extends the overall survival of patients with HER2 overexpressing breast cancer, about half of individuals with HER2-overexpressing breast cancer do not respond to trastuzumab-based therapies due to multiple resistance mechanisms. Therefore, acquired and de novo resistance to trastuzumab remains an important issue in the clinical treatment of HER2-overexpressing breast cancer. Our previous studies demonstrated that Brefeldin A-Inhibited Guanine nucleotide-exchange protein 3 (BIG3), which is exclusively overexpressed in the majority of breast cancers, functions as an A-kinase anchoring protein that binds protein kinase A (PKA) and protein phosphatase 1 (PP1Cα), thereby inactivating prohibitin2 (PHB2) suppressive activity through its dephosphorylation on Ser39. We further developed the stapled dominant-negative peptide (stERAP; stapled ERAP), which is designed to specifically inhibit the BIG3-PHB2 interaction and improve duration of their anti-tumor effects. Here we newly report that stERAP has significant suppressive effects on the HER2 signaling network by activating the tumor suppressive ability of PHB2. Intrinsic PHB2 released from BIG3 by stERAP was rapidly serine- and threonine-phosphorylated via PKCα and/or TTK, which are essential for its tumor suppressive activity, and effectively disrupted the HER2-HER3 interaction associated with acquired resistance to trastuzumab, resulting in significant reduction of proliferation of HER2-overexpressing breast cancer cells (IC50 = 54 nM in SK-BR-3 cells). We also confirm that stERAP inhibited HER2 phosphorylation on Thr488, HER2-HER3 interaction, and NF-κB pathway, which are associated with trastuzumab-resistance, respectively, resulting in significant suppression of growth of trastuzumab-resistant breast cancer cells. More importantly, stERAP treatment led to the enhancement of trastuzumab-sensitivity, resulting in a synergistic growth suppression of HER2-overexpressing and trastuzumab-resistant breast cancer cells, respectively. Our findings strongly suggest that stERAP is a novel promising anti-cancer drug to suppress the growth of trastuzumab-resistant breast cancer in clinical use.

Abstract
Triple negative breast cancers (TNBC), defined by the lack of estrogen and progesterone receptors and HER2 gene amplification, is a heterogeneous and clinically aggressive disease due to the lack of beneficial therapeutic targets. Even though one of the most major risk for the development of TNBC is carrying a deleterious germline and somatic mutations of BRCA1 are not frequently found in sporadic cases of TNBC. Therefore, we aimed to search genomic alterations in TNBC cases by whole-exome sequencing analysis of genomic DNAs from 36 Japanese patients with TNBC compared with their corresponding normal. We identified 36 genes that were recurrently mutated (>10% of cases) in TNBC cases, including TP53 and PIK3CA as described in the previous next generation sequencing analysis of TNBC cases. Remarkably, we identified a number of epigenetic-related genes involved in histone modification and DNA methylation, which were mutated in 20 out of 36 (55.6%) cases. Among them, we focused on spalt like transcription factor 3 (SALL3) gene which shows recurrent somatic mutations, and are most frequently downregulated in TNBC cases. Nonsense-mutation of SALL3 (E169X) completely abolish its binding to DNAMT3A. Ectopic overexpression of the wildtype SALL3, but not the somatically mutated SALL3 into BT549 breast cancer cells, which expresses low level of SALL3 gene, caused the significant suppression of cell growth. Importantly, SALL3 gene was frequently hypermethylated and transcriptionally silenced in only TNBC cases, but not in other types of breast cancer using TCGA data sets. Moreover, the expression of SALL3 was restored after treatments of 5-aza-2'-deoxycitidine (5-aza-dC) in TNBC cell line, HCC1937. Notably, siRNA-mediated knockdown of SALL3 expression in BT20 cells enhanced chemoresistance against paclitaxel and docetaxel, respectively. Moreover, low expression of SALL3 was associated with significantly shorter relapse free survival. Our findings provide the evidence of a pathophysiological role for SALL3 as a tumor suppressor which is possibly associated with carcinogenesis for TNBC.

Abstract
Abstract
Bladder cancer is the most common malignancy of the urinary tract worldwide. Approximately 70% of cases are diagnosed as non-muscle-invasive bladder cancer (NMIBC), while the remaining 30% of cases are classified as muscle-invasive bladder cancer (MIBC). Evidence based on molecular biology has highlighted that the aggressiveness of MIBC advances through a multistep mechanism due to many genomic alterations. Notably, alterations of TP53 and EGFR pathways frequently occur in bladder cancers and are associated with poor prognosis, respectively. However, the connection between the overexpression of EGFR and the p53 mutation in multistep carcinogenesis and the progression of MIBC remains unknown. Here we report the distinct critical roles of DEAD box polypeptide 31 (DDX31) in the multistep progression of muscle invasive bladder cancer (MIBC) through its sequential interaction with mutant p53 (mutp53) and EGFR. In early MIBC cells, nuclear DDX31 acts as a transcriptional co-activator that binds to mutp53/SP1 and enhances mutp53 transcriptional activation, thereby upregulating the EPB41L4B gene, which plays a critical role in metastatic behavior and promotes the invasion and migration of MIBC. Notably, in advanced MIBC, cytoplasmic DDX31, which is transported from the nucleus, functions as an adaptor scaffold protein that forms a complex with EGFR via its interaction with phosho-nucleolin (NCL), leading to constitutive activation of EGFR-Akt signaling. Significantly, high expression of both cytoplasmic DDX31 and p53 proteins is correlated with a poor prognosis in MIBC patients. More importantly, blocking the DDX31-NCL interaction via a dominant-negative peptide led to downregulation of EGFR-Akt signaling, resulting in a significant anti-tumoral effect of bladder cancer in vivo. Our findings reveal that DDX31 cooperates with mutp53 and EGFR to promote the multistep progression of MIBC and that inhibition of DDX31-NCL formation may lead to potential treatment strategies for advanced MIBC.

Abstract
For viroids, pollen transmission is an important transmission pathway to progeny seeds and new hosts. In the current study, we found that Tomato planta macho viroid (TPMVd)-but not Potato spindle tuber viroid (PSTVd)-was horizontally transmitted by pollen from petunia plants. Using tissue-printing hybridization to track the changes in viroid distribution after pollination, we noted that TPMVd was present in petunia stigma, styles, and eventually ovaries, whereas PSTVd was detected in the stigma and upper style but not the ovary. These findings suggest that horizontal transmission of viroids depends on the infection of the lower style and ovary during the elongation of pollen tubes after pollination. Additionally, TPMVd was transmitted horizontally, leading to systematic infection, when we used TPMVd-infected petunia pollen to pollinate the flowers of healthy tomato plants. Fertilization typically does not occur after heterologous pollination and thus likely is not required to accomplish horizontal transmission of viroids.

Abstract
Craniofacial development requires a set of patterning codes that define the identities of postmigratory mesenchymal cells in a region-specific manner, in which locally expressed morphogens, including fibroblast growth factors (FGFs) and bone morphogenetic proteins (BMPs), provide instructive cues. Msx2, a bona fide target of BMP signaling, is a transcription factor regulating Runx2 and osterix (Osx), whose mutations are associated with cranial deformities in humans. Here we show that Msx2 defines osteo-chondro precursor cells in specific regions of the craniofacial mesenchyme at the postmigratory stage, particularly in the mandibular process and the posterior cranial vault. Analysis of Msx2-creER mice revealed that early mesenchymal cells in proximity to the BMP4-expressing mesenchyme were marked upon tamoxifen injection, and their descendants contributed to diverse types of mesenchymal cells in the later stage, such as chondrocytes and perichondrial cells of the transient cartilage, as well as osteoblasts and suture mesenchymal cells. By contrast, Osx-creER marked osteoblast precursors at the later stage, and their descendants continued to become osteoblasts well into the postnatal stage. Therefore, Msx2 marks spatially restricted populations of mesenchymal precursor cells with diverse differentiation potential, suggesting that extrinsic molecular cues can dictate the nature of postmigratory mesenchymal cells in craniofacial development.

Abstract
Triple-negative breast cancer (TNBC), defined as breast cancer lacking estrogen- and progesterone‑receptor expression and human epidermal growth factor receptor 2 (HER2) amplification, is a heterogeneous disease. RNA-sequencing analysis of 15 TNBC specimens and The Cancer Genome Atlas-TNBC dataset analysis identified the frequent downregulation of leucine-rich repeat-containing 26 (LRRC26), which negatively regulates nuclear factor-κB (NF-κB) signaling, in TNBC tissues. Quantitative polymerase chain reaction and bisulfite pyrosequencing analyses revealed that LRRC26 was frequently silenced in TNBC tissues and cell lines as a result of promoter methylation. LRRC26 expression was restored by 5-aza-2'-deoxycytidine (5'-aza-dC) treatment in HCC1937 TNBC cells, which lack LRRC26 expression. Notably, small interfering RNA-mediated knockdown of LRRC26 expression significantly enhanced the anchorage-independent growth, invasion and migration of HCC70 cells, whereas ectopic overexpression of LRRC26 in BT20 cells suppressed their invasion and migration. Conversely, neither knockdown nor overexpression of LRRC26 had an effect on cell viability in the absence of tumor necrosis factor-α (TNF-α) stimulation. Meanwhile, overexpression of LRRC26 caused the reduction of TNF-α-mediated NF-κB luciferase reporter activity, whereas depleting LRRC26 expression resulted in the upregulation of TNF-α-mediated NF-κB downstream genes [interleukin-6 (IL-6), IL-8 and C-X-C motif chemokine ligand-1]. Taken together, these findings demonstrate that LRRC26 is frequently downregulated in TNBC due to DNA methylation and that it suppresses the TNF-α-independent anchorage-independent growth, invasion and migration of TNBC cells. Loss of LRRC26 function may be a critical event in the aggressiveness of TNBC cells through a TNF-α/NF-κB-independent mechanism.

Abstract
The p53 and EGFR pathways are frequently altered in bladder cancer, yet their contributions to its progression remain elusive. Here we report that DEAD box polypeptide 31 (DDX31) plays a critical role in the multistep progression of muscle-invasive bladder cancer (MIBC) through its sequential interactions with mutant p53 (mutp53) and EGFR. In early MIBC cells, nuclear DDX31-bound mutp53/SP1 enhanced mutp53 transcriptional activation, leading to migration and invasion of MIBC. Cytoplasmic DDX31 also bound EGFR and phospho-nucleolin in advanced MIBC, leading to EGFR-Akt signaling activation. High expression of both cytoplasmic DDX31 and p53 proteins correlated with poor prognosis in patients with MIBC, and blocking the DDX31/NCL interaction resulted in downregulation of EGFR/Akt signaling, eliciting an in vivo antitumor effect against bladder cancer. These findings reveal that DDX31 cooperates with mutp53 and EGFR to promote progression of MIBC, and inhibition of DDX31/NCL formation may lead to potential treatment strategies for advanced MIBC.Significance: DDX31 cooperates with mutp53 and EGFR to promote progression of muscle invasive bladder cancer.

Abstract
Proteins in solution are conventionally considered macromolecules. Dynamic microscopic structures in supersaturated protein solutions have received increasing attention in the study of protein crystallisation and the formation of misfolded aggregates. Here, we present a method for observing rotational dynamic structures that can detect the interaction of nanoscale lysozyme protein networks via diffracted X-ray tracking (DXT). Our DXT analysis demonstrated that the rearrangement behaviours of lysozyme networks or clusters, which are driven by local density and concentration fluctuations, generate force fields on the femtonewton to attonewton (fN – aN) scale. This quantitative parameter was previously observed in our experiments on supersaturated inorganic solutions. This commonality provides a way to clarify the solution structures of a variety of supersaturated solutions as well as to control nucleation and crystallisation in supersaturated solutions.

Abstract
Tomato spotted wilt virus (TSWV) causes significant losses in the production of the ornamental plant Dahlia variabilis in Japan. The purpose of this study was to examine the distribution of TSWV in dahlia plants and identify plant parts that can be used in the selection of TSWV-free plants. The distribution of TSWV was investigated using reverse transcriptional polymerase chain reaction (RT-PCR) and tissue blot immunoassay. The detection rate of TSWV in latent infected compound leaves was the highest in the petiole, and it decreased from the veins and rachis to the lamina. The tissue blot immunoassays of the leaflets showed an uneven distribution of TSWV, especially along the edge of the leaf blade. In stems, the detection rate of TSWV was high partway up the stem compared to that in the upper and the lower parts of the stem during the vegetative growth stage. A highly uneven distribution was observed in the bulb. Our results indicated that middle parts of the stem as well as the petioles, rachis, and veins of compound leaves are suitable for detection of TSWV in dahlias. This study is the first to report uneven distribution of TSWV in dahlia plants. SIGNIFICANCE AND IMPACT OF THE STUDY In this study, the distribution of Tomato spotted wilt virus (TSWV) in various parts of dahlia plants was investigated for the first time. The distribution of TSWV was uneven in compound leaves, leaflets, stems, and bulbs. The middle parts of the stem or the petiole and leaf veins should be sampled to detect TSWV when selecting healthy plants.

Abstract
We previously reported that one of the ethylene response factors (ERFs), NtERF3, and other members of the subgroup VIII-a ERFs of the AP2/ERF family exhibit cell death-inducing ability in tobacco leaves. In this study, we focused on the involvement of NtERF3 in a cell death signalling pathway in tobacco plants, particularly downstream of NtSIPK/NtWIPK and NtWRKY1, which are mitogen-activated protein kinases and a phosphorylation substrate of NtSIPK, respectively. An ERF-associated amphiphilic repression (EAR) motif-deficient NtERF3b mutant (NtERF3bΔEAR) that lacked cell death-inducing ability suppressed the induction of cell death caused by NtERF3a. The transient co-expression of NtERF3bΔEAR suppressed the hypersensitive reaction (HR)-like cell death induced by NtSIPK and NtWRKY1. The induction of cell death by NtSIPK and NtWRKY1 was also inhibited in transgenic plants expressing NtERF3bΔEAR. Analysis of gene expression, ethylene production and cell death symptoms in salicylic acid-deficient tobacco plants suggested the existence of some feedback regulation in the HR cell death signalling pathway mediated by SIPK/WIPK and WRKY1. Overall, these results suggest that NtERF3 functions downstream of NtSIPK/NtWIPK and NtWRKY1 in a cell death signalling pathway, with some feedback regulation.

Abstract
AIMS Primary central nervous system lymphoma (PCNSL) manifest aggressive clinical behaviour and have poor prognosis. Although constitutive activation of the nuclear factor-κB (NF-κB) pathway has been documented, knowledge about the genetic alterations leading to the impairment of the NF-κB pathway in PCNSLs is still limited. This study was aimed to unravel the underlying genetic profiles of PCNSL. METHODS We conducted the systematic sequencing of 21 genes relevant to the NF-κB signalling network for 71 PCNSLs as well as the pyrosequencing of CD79B and MYD88 mutation hotspots in a further 35 PCNSLs and 46 glioblastomas (GBMs) for validation. RESULTS The results showed that 68 out of 71 PCNSLs had mutations in the NF-κB gene network, most commonly affecting CD79B (83%), MYD88 (76%), TBL1XR1 (23%), PRDM1 (20%) and CREBBP1 (20%). These mutations, particularly CD79B and MYD88, frequently coincided within each tumour in various combinations, simultaneously affecting diverse pathways within the network. No GBMs had hotspot mutation of CD79B Y196 and MYD88 L265. CONCLUSIONS The prevalence of CD79B and MYD88 mutations in PCNSLs was considerably higher than reported in systemic diffuse large B-cell lymphomas. This observation could reflect the paucity of antigen stimuli from the immune system in the central nervous system (CNS) and the necessity to substitute them by the constitutive activation of CD79B and MYD88 that would initiate the signalling cascades. These hotspot mutations may serve as a genetic hallmark for PCNSL serving as a genetic marker for diagnose and potential targets for molecular therapy.
