Abstract
Antipsychotic treatment is vital for patients with schizophrenia even in the perinatal period, but the impact at the molecular biological level on offspring is unclear. The aim of the present study was to investigate the effects of intraperitoneal haloperidol injection to pregnant mice on glutamate and GABA receptors in the brain of offspring mice. Eight-week-old pregnant mice were treated with either intraperitoneal haloperidol or normal saline injection, and their offspring were defined as F1 mice. In addition, eight-week-old male mice were used as acute mice that were intraperitoneally injected with haloperidol or normal saline for 20 days. mRNA expression levels were measured by RT-qPCR. Western blotting was performed of the frontal lobes of F1 mice. In the hippocampi of F1 mice, Grik3 (p = 0.023) and Gabra3 (p = 0.004) mRNA expression levels were significantly higher in the haloperidol group than in the control group, whereas Gria2 (p < 0.001) and Grin2a (p < 0.001) mRNA expression levels were significantly lower in the haloperidol group than in the control group. Gria2 (p = 0.015), and Grik3 (p = 0.037), and Grin2a (p = 0.012) mRNA expression levels were significantly lower in the haloperidol group than in the control group in the frontal lobes of F1 mice. In the hippocampi of acute mice, Grik3 (p = 0.049) and Gabra3 (p = 0.007) mRNA expression levels were significantly decreased in the haloperidol group. Fetal exposure to haloperidol can affect glutamate and GABA receptors through mRNA expression changes in the brain of offspring.

Abstract
BACKGROUND The onset of schizophrenia is associated with both genetic and environmental risks during brain development. Environmental factors during pregnancy can represent risk factors for schizophrenia, and we have previously reported that several microRNA and mRNA expression changes in fetal brains exposed to haloperidol during pregnancy may be related to the onset of this disease. This study aimed to replicate that research and focused on apoptotic-related gene expression changes. METHODS Haloperidol (1mg/kg) or aripiprazole (1mg/kg) was injected into pregnant mice. Using RNA sequencing for the hippocampus of each offspring born from pregnant mice exposed to haloperidol, we analyzed genes identified as changed in our previous report and validated two apoptosis-related genes (Cdkn1a and Apaf1) using quantitative polymerase chain reaction (qPCR) methods. Furthermore, we attempted to elucidate the direct effects of haloperidol and aripiprazole on those mRNA expressions in in vitro experiments. RESULTS RNA sequencing successfully replicated 16 up-regulated and 5 down-regulated genes in this study. Of those, up-regulations of Cdkn1a and Apaf1 mRNA expression were successfully validated by direct quantification. Moreover, haloperidol and aripiprazole dose-dependent upregulation of both mRNA expressions were confirmed in a Neuro2a cell line. CONCLUSIONS In the hippocampus of offspring, intraperitoneal injection of haloperidol to pregnant mice induced up-regulation of apoptotic genes that representing the phenotypic change without apoptosis. These findings will be useful for understanding the molecular biological mechanisms underlying the effects of antipsychotics on the fetal brain.

Abstract
BACKGROUND We explored the gene expression levels in the brain of 3xTg-AD model mice to elucidate the molecular pathological changes from the early to end stages of Alzheimer's disease (AD). OBJECTIVE We re-analyzed our previously published microarray data obtained from the hippocampus of 3xTg-AD model mice at 12 and 52 weeks of age. METHODS Functional annotation and network analyses of the up- and downregulated differentially expressed genes (DEGs) in mice aged 12 to 52 weeks were performed. Validation tests for gamma-aminobutyric acid (GABA)-related genes were also performed by quantitative polymerase chain reaction (qPCR). RESULTS In total, 644 DEGs were upregulated and 624 DEGs were downregulated in the hippocampus of both the 12- and 52-week-old 3xTg-AD mice. In the functional analysis of the upregulated DEGs, 330 gene ontology biological process terms, including immune response, were found, and they interacted with each other in the network analysis. In the functional analysis of the downregulated DEGs, 90 biological process terms, including several terms related to membrane potential and synapse function, were found, and they also interacted with each other in the network analysis. In the qPCR validation test, significant downregulation was seen for Gabrg3 at the ages of 12 (p = 0.02) and 36 (p = 0.005) weeks, Gabbr1 at the age of 52 weeks (p = 0.001), and Gabrr2 at the age of 36 weeks (p = 0.02). CONCLUSION Changes in immune response and GABAergic neurotransmission may occur in the brain of 3xTg mice from the early to end stages of AD.

Abstract
BACKGROUND Autism spectrum disorder (ASD), is a neurodevelopmental disorder that is known to have a high degree of heritability. Diagnosis of ASD is difficult because of the high heterogeneity of the clinical symptoms. MicroRNAs (miRNAs) can potentially be diagnostic biomarkers for ASD, and several studies have shown the relationship between miRNAs and ASD pathogenesis. In this study, we investigated ten miRNA and mRNA expression of target genes in peripheral blood to explore a diagnostic biomarker for ASD. METHODS We recruited control and ASD subjects for the discovery cohort (n = 6, each) and replication cohort (n = 20, each). Using qPCR, miRNA and mRNA expression was measured using the SYBR green and probe methods, respectively. In-silico prediction was used for identifying target genes of miRNAs. An in vitro experiment using HEK293 cells was conducted to investigate whether miR-15b-5p modulates the predicted target genes (TGFBR3 and MYBL1). RESULTS miR-15b-5p expression indicated an increased trend in the discovery cohort (p = 0.052) and a significant upregulation in the replication cohort (p = 0.021). In-silico analysis revealed that miR-15b-5p is relevant to cell development and Wnt signaling. The decreased trends of TGFBR3 and MYBL expression were the same as in previous RNA-seq data. MiR-15b-5p positively regulated TGFBR3 expression in in vitro experiments. CONCLUSIONS Upregulated miR-15b-5p expression may represent a useful diagnostic marker of ASD subjects, and it may regulate TGFBR3 mRNA expression. These findings indicate a new perspective in the understanding of the pathogenesis of ASD.

Abstract
OBJECTIVES Recently, the expression changes of microRNAs (miRNAs) in the serum exosomes (EXO) of schizophrenia (SCZ) have been reported. The aim of this study was to investigate the global expression changes of miRNA derived from the plasma EXO of patients with treatment-resistant schizophrenia (TRS) and the effects of clozapine on miRNA expression. METHODS Global miRNA expression changes in plasma EXO between TRS and controls were studied using microarray analysis. Then, miRNA expressions among TRS, non-TRS, and controls were confirmed with quantitative qPCR experiments. We also studied changes in EXO miRNA expression with in-vitro SH-SY5Y cells. RESULTS A microarray for miRNA expression analysis (nine controls vs. nine patients with TRS) revealed 13 up- and 18 downregulated miRNAs that were relevant to neuronal and brain development based on gene ontology analysis. Of those, upregulated miR-675-3p expression was successfully validated in the same cohort by qPCR experiments. Conversely, miR-675-3p expression levels were significantly decreased in the non-TRS cohort (50 controls vs. 50 patients without TRS without clozapine treatment). CONCLUSIONS We identified global miRNA changes in plasma EXO derived from patients with SCZ that were relevant to neuronal functions, among which, hsa-miR-675-3p expression was upregulated by clozapine treatment.

Abstract
BACKGROUND Schizophrenia is a mental disorder caused by both environmental and genetic factors. Prenatal exposure to antipsychotics, an environmental factor for the fetal brain, induces apoptotic neurodegeneration and cognitive impairment of offspring similar to schizophrenia. The aim was to investigate molecular biological changes in the fetal hippocampus exposed to haloperidol (HAL) by RNA expression as a model of the disorder. METHODS HAL (1 mg/kg/d) was administered to pregnant mice. Upregulated and downregulated gene expressions in the hippocampus of offspring were studied with RNA-sequencing and validated with the qPCR method, and micro-RNA (miR) regulating mRNA expressional changes was predicted by in silico analysis. An in vitro experiment was used to identify the miRNA using a dual-luciferase assay. RESULTS There were significant gene expressional changes (1370 upregulated and 1260 downregulated genes) in the HAL group compared with the control group on RNA-sequencing analysis (P < .05 and q < 0.05). Of them, the increase of Nr3c1 mRNA expression was successfully validated, and in silico analysis predicted that microRNA-137-3p (miR-137-3p) possibly regulates that gene's expression. The expression of miR-137-3p in the hippocampus of offspring was significantly decreased in the first generation, but it increased in the second generation. In vitro experiments with Neuro2a cells showed that miR-137-3p inversely regulated Nr3c1 mRNA expression, which was upregulated in the HAL group. CONCLUSIONS These findings will be key for understanding the impact of the molecular biological effects of antipsychotics on the fetal brain.

Abstract
Background: Late-onset Alzheimer’s disease (LOAD) is a complex disease in which neuroinflammation plays an important pathophysiological role, and exposure to neurotoxic substrates such as aldehydes may contribute. Blood mRNA expression levels of neuroinflammation-related genes appear to be potential biological markers of LOAD. A relationship between ALDH2 and LOAD has been suggested. Objective: Our objective was to examine blood ALDH2 expression in Japanese LOAD patients, conduct a genetic association study, and add new studies to an extended meta-analysis of the Asian population. Methods: A blood expression study (45 AD subjects, 54 controls) in which total RNA was isolated from whole peripheral blood samples and ALDH2 expression measured was conducted. In addition, a genetic association study (271 AD subjects, 492 controls) using genomic DNA from whole peripheral blood samples was conducted. Finally, a meta-analysis examined the relationship between ALDH2*2 frequency and the risk of LOAD. Results: ALDH2 mRNA expression was significantly higher in LOAD than in controls, and also higher in men with LOAD than in women with LOAD (p = 0.043). The genotypes in the two classified groups and the allele frequency were significantly different between AD and control subjects. The meta-analysis showed a significant difference in the ALDH2*2 allele, with an increased AD risk (OR = 1.38; 95% CI = 1.02–1.85; p = 0.0348, I2 = 81.1%). Conclusion: There was a significant increase in blood ALDH2 expression, and a genetic association with ALDH2*2 in LOAD. ALDH2 may have significant roles in the pathogenesis of LOAD in the Asian population.

Abstract
BACKGROUND Phosphatidylinositol-binding clathrin assembly protein (PICALM) is a validated genetic risk factor for late-onset Alzheimer's disease (AD) and is associated with other neurodegenerative diseases. However, PICALM expression in the blood of neurodegenerative diseases remains elusive. OBJECTIVE This study aimed to assess the usefulness of PICALM expression levels in the blood of patients with AD, Parkinson's disease (PD), dementia with Lewy bodies (DLB), and geriatric major depressive disorder (MDD) as a diagnostic biomarker. METHODS In total, 45, 20, 21, and 19 patients with AD, PD, DLB, and geriatric MDD, respectively, and 54 healthy controls (HCs) were enrolled in the study. Expression data from Gene Expression Omnibus database (GSE97760), (GSE133347) and (GSE98793), (GSE48350), and (GSE144459) were used to validate the ability of biomarkers in the blood of patients with AD, PD, geriatric MDD, and a postmortem human AD brain and animal model of AD (3xTg-AD mouse), respectively. RESULTS PICALM mRNA expression in human blood was significantly increased in patients with AD compared with that in HCs. PICALM mRNA expression and age were negatively correlated only in patients with AD. PICALM mRNA expression in human blood was significantly lower in patients with PD than in HCs. No changes in PICALM mRNA expression were found in patients with DLB and geriatric MDD. CONCLUSION PICALM mRNA expression in blood was higher in patients with AD, but lower in patients with PD, which suggests that PICALM mRNA expression in human blood may be a useful biomarker for differentiating neurodegenerative diseases and geriatric MDD.

Abstract
BACKGROUND Cyclin-dependent kinase inhibitor 2A (CDKN2A) is an important gene in cellular senescence and aging. OBJECTIVE This study assessed the utility of blood CDKN2A mRNA expression levels and methylation status as a potential biomarker for aging and the pathogenesis of Alzheimer's disease (AD). METHODS The correlation between CDKN2A mRNA expression levels and age was examined in 45 healthy subjects, after which mRNA expression levels were compared among 46 AD patients, 20 mild cognitive impairment due to AD patients, 21 Parkinson's disease patients, 21 dementia with Lewy bodies patients, and 55 older healthy controls. The methylation rates of the second exon of the CDKN2A gene, known to influence its expression levels, was also examined. RESULTS A significant correlation between CDKN2A mRNA expression levels and age was found (Spearman's rank correlation coefficient: r = 0.407, p = 0.005). CDKN2A mRNA expression levels in blood were significantly decreased in AD patients, although those of healthy controls were significantly increased with age. Further, only in AD patients were CDKN2A mRNA expression levels significantly and positively correlated with methylation rates. CONCLUSION Although further research with a larger sample size is needed to elucidate the relationships between CDKN2A gene expression in blood and the development of other neurodegenerative diseases, CDKN2A mRNA expression in blood may be a biomarker for differentiating AD from normal aging and other neurodegenerative diseases.

Abstract
The pathophysiology of delayed carbon monoxide (CO) encephalopathy remains unclear. In this study, the effects of CO exposure on the dentate gyrus (DG) were investigated in a Wistar rat model by histochemical and molecular methods. Model rats showed significant cognitive impairment in the passive-avoidance test beginning 7 days after CO exposure. Immunohistochemistry showed that compared to the control, the cell number of SRY (sex-determining region Y)-box 2 (SOX2)+/brain lipid binding protein (BLBP)+/glial fibrillary acidic protein (GFAP)+ cells in the DG was significantly less, but the number of SOX2+/GFAP− cells was not, reflecting a decreased number of type 1 and type 2a neural precursor cells. Compared to the control, the numbers of CD11b+ cells and neuron glial antigen 2+ cells were significantly less, but the number of SOX2−/GFAP+ cells was not. Flow cytometry showed that the percent of live microglial cells isolated from the hippocampus in this CO rat model was significantly lower than in controls. Furthermore, mRNA expression of fibroblast growth factor 2 and glial cell-derived neurotrophic factor, which are neurogenic factors, was significantly decreased in that area. We conclude that, in this rat model, there is an association between delayed cognitive impairment with dysregulated adult hippocampal neurogenesis and glial changes in delayed CO encephalopathy.

Abstract
The testing of pathological biomarkers of Alzheimer's disease (AD), such as amyloid beta and tau, is time-consuming, expensive, and invasive. Here, we used 3xTg-AD mice to identify and validate putative novel blood transcriptome biomarkers of AD that can potentially be identified in the blood of patients. mRNA was extracted from the blood and hippocampus of 3xTg-AD and control mice at different ages and used for microarray analysis. Network and functional analyses revealed that the differentially expressed genes between AD and control mice modulated the immune and neuroinflammation systems. Five novel gene transcripts (Cdkn2a, Apobec3, Magi2, Parp3, and Cass4) showed significant increases with age, and their expression in the blood was collated with that in the hippocampus only in AD mice. We further assessed previously identified candidate biomarker genes. The expression of Trem1 and Trem2 in both the blood and brain was significantly increased with age. Decreased Tomm40 and increased Pink1 mRNA levels were observed in the mouse blood. The changes in the expression of Snca and Apoe mRNA in the mouse blood and brain were similar to those found in human AD blood. Our results demonstrated that the immune and neuroinflammatory system is involved in the pathophysiologies of aging and AD and that the blood transcriptome might be useful as a biomarker of AD.

Abstract
CTL-associated antigen 4 (CTLA4) and its downstream signals compose an important mechanism that suppresses immune activity. Recent studies have shown that immune abnormalities are associated with the pathogenesis of schizophrenia (SCZ), but little research has been performed on the relevance of CTLA4 and SCZ. In the present study, we investigated the relationship between CTLA4 mRNA expression and SCZ. We examined the expression of CTLA4 mRNA in blood from patients with SCZ, bipolar disorder (BD), and major depressive disorder (MDD). We compared 50 SCZ subjects, 46 BD subjects, and 63 MDD subjects with age- and sex-matched healthy controls (HCs). Quantitative real-time PCR was performed to examine CTLA4 mRNA expression in peripheral blood using TaqMan probes. Levels of CTLA4 mRNA expression were significantly lower in patients with SCZ compared with HCs (p < 0.001), whereas no differences were found between affective disorder (BD and MDD) patients and HCs. We analyzed the correlation between CTLA4 mRNA expression and clinical parameters, but no significant correlation was found. The expression of CTLA4 mRNA was lower specifically in SCZ, suggesting that abnormal CTLA4 expression may be particularly related to the pathogenesis of SCZ. CTLA4 may be a useful diagnostic marker and a potential therapeutic target of SCZ.

Abstract
The neuroprotective effect of ghrelin has recently been reported in Alzheimer's disease (AD). Ghrelin is converted from des-acyl ghrelin to the activated form, acyl ghrelin, by membrane bound o-acyltransferase 4 (MBOAT4), and then binds to growth hormone secretagogue receptor (GHS-R). We examined the levels of plasma acyl/des-acyl ghrelin in 75 AD subjects and age- and sex-matched controls, as well as the DNA methylation and mRNA expression of MBOAT4 and GHS-R in peripheral leukocytes. The acyl ghrelin concentration was significantly higher in AD subjects than in controls (2.18 ± 1.25 vs. 1.49 ± 2.3, p = 0.001). The methylation rate of MBOAT4 CpG 2 was significantly lower in AD subjects than in controls (4.0 ± 0.9 vs. 4.7 ± 1.2, p < 0.001). The mRNA expression levels of MBOAT4 and GHS-R1b were significantly higher in AD subjects than in controls (MBOAT4: 1.10 ± 0.48 vs. 1.0 ± 0.55, p = 0.049; GHS-R1b: 1.76 ± 3.18 vs. 1.0 ± 1.56, p = 0.030). These changes in the ghrelin cascade in peripheral blood may reflect those in the brain, and may be a neuroprotective biomarker in AD.

Abstract
Despite the continuing debate about the amyloid hypothesis in Alzheimer's disease (AD), the precise pathogenesis is still unclear. Mixed pathology is common and multiple different protein aggregates are seen in human postmortem brains. Aggregates consisting of the alpha-synuclein protein encoded by the Synuclein Alpha gene (SCNA) are common in both dementia with Lewy bodies and AD. We examined SNCA mRNA expression and methylation rates of the CpG island at intron 1 of SNCA in peripheral leukocytes in 50 AD and age- and sex-matched control subjects to verify whether alpha-synuclein pathology affects the AD pathogenesis. SNCA mRNA expression in AD subjects was significantly higher than that in control subjects (1.62±0.73 versus 0.98±0.50, p < 0.001). We found significant differences between AD and control subjects at seven CpG sites (average rate; 8.8±2.7 versus 9.5±2.5, respectively: p = 0.027). The methylation rates tended to be lower in AD subjects at all CpG sites. We conclude that mRNA expression and methylation of SNCA intron 1 are altered in AD, which may be caused by Lewy body pathology in AD.

Abstract
CD200 induces immunosuppression in myeloid cells expressing its receptor CD200R, which may have consequences for tumor immunity. We found that human carcinoma tissues express not only full-length CD200 (CD200L) but also its truncated form, CD200S. Although CD200S is reported to antagonize the immunosuppressive actions of CD200L, the role of CD200S in tumor immunity has never been investigated. We established rat C6 glioma cell lines that expressed either CD200L or CD200S; the original C6 cell line did not express CD200 molecules. The cell lines showed no significant differences in growth. Upon transplantation into the neonatal Wistar rat forebrain parenchyma, rats transplanted with C6-CD200S cells survived for a significantly longer period than those transplanted with the original C6 and C6-CD200L cells. The C6-CD200S tumors were smaller than the C6-CD200L or C6-original tumors, and many apoptotic cells were found in the tumor cell aggregates. Tumor-associated macrophages (TAMs) in C6-CD200S tumors displayed dendritic cell (DC)-like morphology with multiple processes and CD86 expression. Furthermore, CD3+, CD4+ or CD8+ cells were more frequently found in C6-CD200S tumors, and the expression of DC markers, granzyme, and perforin was increased in C6-CD200S tumors. Isolated TAMs from original C6 tumors were co-cultured with C6-CD200S cells and showed increased expression of DC markers. These results suggest that CD200S activates TAMs to become DC-like antigen presenting cells, leading to the activation of CD8+ cytotoxic T lymphocytes, which induce apoptotic elimination of tumor cells. The findings on CD200S action may provide a novel therapeutic modality for the treatment of carcinomas.

Abstract
AIM It is difficult to diagnose dementia with Lewy bodies (DLB) because it exhibits clinical and neuropathological overlap with both Alzheimer's disease and Parkinson's disease. The α-synuclein protein is a major component of Lewy bodies, and accumulation of α-synuclein aggregates causes synaptic dysfunction in DLB. Epigenetic changes at the synuclein alpha ( SNCA ) gene may be involved in DLB pathogenesis. METHODS We examined DNA methylation rates at 10 CpG sites located in intron 1 of SNCA and SNCA mRNA expression in peripheral leukocytes to compare DLB patients (n = 20; nine men, 11 women; age = 78.8 ± 7.7 years) with healthy controls (n = 20; eight men, 12 women; age = 77.0 ± 6.9 years). RESULTS The methylation rate at CpG 4 ( P = 0.002) and the overall mean methylation rate at these sites (P < 0.001) were significantly lower in DLB patients than in healthy controls after Bonferroni correction. Although SNCA126 , a partial form of SNCA mRNA expression, was significantly increased in DLB ( P = 0.017), there was no significant difference in total SNCA mRNA expression between DLB patients and healthy controls ( P = 0.165). No correlation was observed between SCNA mRNA expression levels and blood DNA methylation rates in either DLB or healthy controls. CONCLUSION Our findings indicated that lower methylation rates may be a biomarker for DLB.

Abstract
Based on our previously developed scheme to stabilize nonplanar optical resonant cavities utilizing polarization caused by a geometric phase in electromagnetic waves traveling along a twisted path, we report an application of the technique for a cavity installed in the Accelerator Test Facility, a 1.3-GeV electron beam accelerator at KEK, in which photons are generated by laser-Compton scattering. We successfully achieved a power enhancement of 1200 with 1.4% fluctuation, which means that the optical path length of the cavity has been controlled with a precision of 14 pm under an accelerator environment. In addition, polarization switching utilizing a geometric phase of the nonplanar cavity was demonstrated.

Abstract
BACKGROUND Drug resistance is a major obstacle for the efficacy of chemotherapeutic treatment of tumors. Oct-3/4, a self-renewal regulator in stem cells, is expressed in various kinds of solid tumors including glioblastoma. Although Oct-3/4 expression has been implicated in the malignancy and prognosis of glioblastomas, little is known of its involvement in drug resistances of glioblastoma. METHODS The involvement of Oct-3/4 in drug resistance of glioblastoma cells was assessed by lactate dehydrogenase assay, efflux assay of an anticancer drug, poly ADP-ribose polymerase cleavage, and in vivo xenograft experiments. Involvement of a drug efflux pump ATP binding cassette transporter G2 in Oct-3/4-induced drug resistance was evaluated by quantitative PCR analysis and knockdown by shRNA. RESULTS Oct-3/4 decreased the susceptibility to chemotherapeutic drugs by enhancing excretion of drugs through a drug efflux pump gene, ATP binding cassette transporter G2. Moreover, the expression of Oct-3/4 was well correlated to ATP binding cassette transporter G2 expression in clinical GB tissues. CONCLUSION Oct-3/4 elevated the ATP binding cassette transporter G2 expression, leading to acquisition of a drug-resistant phenotype by glioblastoma cells. GENERAL SIGNIFICANCE If the drug-resistance of glioblastoma cells could be suppressed, it should be a highly ameliorative treatment for glioblastoma patients. Therefore, signaling pathways from Oct-3/4 to ATP binding cassette transporter G2 should be intensively elucidated to develop new therapeutic interventions for better efficacy of anti-cancer drugs.

Abstract
BACKGROUND Quantification of the serum level of BK virus is used as a surrogate marker for the early onset of BK virus nephropathy. However, little is known about the diagnostic value of the urine level of BK virus for nephropathy or the relationship between the serum and urine viral load. We investigated the correlation between urine and serum BK virus levels after renal transplantation. METHODS From November 2008 to August 2013, a total of 270 renal transplant patients who were followed at our institution were included in this study. Urine and serum were collected simultaneously. BK virus levels were quantified in 894 urine and serum samples using a real-time polymerase chain reaction assay. RESULTS BK virus was detected in 178 urine samples and 36 serum samples. Among the BK virus-positive urine subjects, the positive predictive value for viral detection in the serum was 9% (13/147) when the urinary virus level was <10(7) copies/mL and 74% (23/31) when the urinary virus was ≥ 10(7) copies/mL. Serum BK viral levels were ∼2-3 log units lower than those in urine. CONCLUSIONS BK virus was detected more frequently in serum when present in urine at ≥ 10(7) copies/mL after renal transplantation.

Abstract
BACKGROUND Little is known about the timing of polyomavirus reactivation and its presence in urine after renal transplantation. The purpose of this study was to investigate the prevalence of positive polyomavirus in urine at various time points after renal transplantation. METHODS From November 2008 to August 2013, 279 renal transplant patients from our institution were included in this study. One urine sample was collected at 0-3, 4-6, 7-12, 13-24, 25-60, and ≥ 61 months after renal transplantation. A total of 394 urine samples were assessed for the presence of the BK and JC viruses with the use of a real-time polymerase chain reaction assay. RESULTS BK virus was detected in the urine of one-third of patients during the first 6 months. Thereafter, the positivity rate decreased gradually to 12% >5 years after transplantation. The positivity rate for the JC virus in urine was 33%-49% regardless of the post-transplantation phase. CONCLUSIONS BK virus was detected more frequently in urine during the early phase after renal transplantation, whereas the JC virus was detected more consistently.

Abstract
BACKGROUND One of the problems of cadaveric renal transplantation is that its graft survival rate is less than that for living renal transplantation. We aim to study relationships between the graft survival of cadaveric renal transplantation patients and various factors. MATERIALS AND METHODS We retrospectively analyzed 350 cadaveric renal transplantation patients from our institutions from 1983 to 2011. Kaplan-Meier analysis was performed to evaluate graft survival ratios. Using a multivariable Cox regression model, we evaluated the relationship between graft survival and the factors such as age and gender of donor and recipient, body mass index of recipient, duration of hemodialysis, warm ischemic time, and acute rejection (AR), etc. RESULTS Among 235 males and 115 females, the overall mean age was 41 years. Median follow-up was 15 years (2 to 28 years). The graft survival ratio was 97% at 1 year, 85% at 5 years, and 71% at 10 years. Using the Cox regression model, graft survival was affected by donor age (younger than 60 years; hazard ratio [HR] 1.5; 95% confidence interval (CI) 1.0-2.0; P = .027) and early acute rejection (within 3 months; HR 2.1; CI 1.6-2.8; P < .001). CONCLUSIONS The graft survival of cadaveric renal transplantation patients is affected by factors of donor age and early AR.

Abstract
Neural cross-sensitization has been postulated as a mechanism underlying overlaps of chronic pelvic pain disorders such as bladder pain syndrome/interstitial cystitis (BPS/IC) and irritable bowel syndrome (IBS). Animals with experimental colitis have been used to study the underlying mechanisms for overlapped pelvic pain symptoms, and shown to exhibit bladder overactivity evidenced by frequent voiding; however, it has not directly been evaluated whether pain sensation derived from the lower urinary tract is enhanced in colitis models. Also, the cross-sensitization between the colon and urethra has not been studied previously. In the present study, we therefore investigated pain behaviors induced by nociceptive stimuli in the lower urinary tract and the involvement of C-fiber afferent pathways using rats with colitis induced by intracolonic application of 2,4,6-trinitrobenzenesulfonic acid (TNBS). In TNBS-induced colitis rats at 10 days, intravesical application of resiniferatoxin (RTx) induced a significantly greater number of episodes of both licking and freezing behaviors, which were reduced by capsaicin-sensitive C-fiber afferent desensitization. Histochemical studies using fluorescent dye tracers injected into the colon, bladder or urethra showed that dichotomized afferent neurons comprised 6.9-14.5% of L1, L6 and S1 dorsal root ganglion (DRG) neurons innervating the colon or the lower urinary tract. Transient receptor potential vanilloid 1 (TRPV1) mRNA expression was significantly increased in, the bladder, urethra and S1 DRG in colitis rats. An increase in myeloperoxidase (MPO) activity was found in the colon, but not in the bladder or urethra after intracolonic TNBS treatment. These results indicate that TNBS-induced colitis increased pain sensitivity in the bladder and urethra via activation of C-fiber afferent pathways due to colon-to-bladder and colon-to-urethral cross-sensitization, suggesting the contribution of pelvic organ cross-sensitization mechanisms to overlapped pain symptoms in BPS/IC and IBS.

Abstract
A 48-year-old male presented with para-aortic lymph node metastases after surgical resection of a clear cell renal cell carcinoma. After first-line treatment with interferon alpha-2b, he was started on pazopanib and lapatinib. Blood pressure was well controlled with temocapril and amlodipine. Treatment had to be stopped 4 years and 8 months after initiation due to overt proteinuria. Then, sunitinib was started as third-line treatment. During the second cycle of sunitinib, he died due to a Stanford type A aortic dissection. Acute aortic dissection could be an adverse event associated with the long-term use of antiangiogenic tyrosine kinase inhibitors.

Abstract
Background: Eribulin mesilate (eribulin), a non-taxane microtubule dynamics inhibitor, has shown trends towards greater overall survival (OS) compared with progression-free survival in late-stage metastatic breast cancer patients in the clinic. This finding suggests that eribulin may have additional, previously unrecognised antitumour mechanisms beyond its established antimitotic activity. To investigate this possibility, eribulin's effects on the balance between epithelial–mesenchymal transition (EMT) and mesenchymal–epithelial transition (MET) in human breast cancer cells were investigated. Methods: Triple negative breast cancer (TNBC) cells, which are oestrogen receptor (ER−)/progesterone receptor (PR−)/human epithelial growth receptor 2 (HER2−) and have a mesenchymal phenotype, were treated with eribulin for 7 days, followed by measurement of EMT-related gene and protein expression changes in the surviving cells by quantitative real-time PCR (qPCR) and immunoblot, respectively. In addition, proliferation, migration, and invasion assays were also conducted in eribulin-treated cells. To investigate the effects of eribulin on TGF-β/Smad signalling, the phosphorylation status of Smad proteins was analysed. In vivo, the EMT/MET status of TNBC xenografts in mice treated with eribulin was examined by qPCR, immunoblot, and immunohistochemical analysis. Finally, an experimental lung metastasis model was utilised to gauge the metastatic activity of eribulin-treated TNBC in the in vivo setting. Results: Treatment of TNBC cells with eribulin in vitro led to morphological changes consistent with transition from a mesenchymal to an epithelial phenotype. Expression analyses of EMT markers showed that eribulin treatment led to decreased expression of several mesenchymal marker genes, together with increased expression of several epithelial markers. In the TGF-β induced EMT model, eribulin treatment reversed EMT, coincident with inhibition of Smad2 and Smad3 phosphorylation. Consistent with these changes, TNBC cells treated with eribulin for 7 days showed decreased capacity for in vitro migration and invasiveness. In in vivo xenograft models, eribulin treatment reversed EMT and induced MET as assessed by qPCR, immunoblot, and immunohistochemical analyses of epithelial and mesenchymal marker proteins. Finally, surviving TNBC cells pretreated in vitro with eribulin for 7 days led to decreased numbers of lung metastasis when assessed in an in vivo experimental metastasis model. Conclusions: Eribulin exerted significant effects on EMT/MET-related pathway components in human breast cancer cells in vitro and in vivo, consistent with a phenotypic switch from mesenchymal to epithelial states, and corresponding to observed decreases in migration and invasiveness in vitro as well as experimental metastasis in vivo. These preclinical findings may provide a plausible scientific basis for clinical observations of prolonged OS by suppression of further spread of metastasis in breast cancer patients treated with eribulin.

Abstract
A 30-year-old man presented with micturition pain and was diagnosed with a submucosal tumor in the right wall of the bladder with metastasis to the right obturator lymph node. Transurethral resection led to a diagnosis of invasive malignant pheochromocytoma. Radical cystectomy, neobladder reconstruction and bilateral iliac lymph node dissection were performed. Genetic analysis revealed succinate dehydrogenase B-associated hereditary pheochromocytoma/paraganglioma syndrome. 10 months after the operation, he had no evidence of recurrence.

Abstract
We investigated the effects of replication-defective herpes simplex virus (HSV) vector expression of interleukin-4 (IL-4) on bladder overactivity and nociception. HSV vector expressing murine interleukin-4 (S4IL4) or the control vector expressing β-galactosidase (SHZ) were injected to the rat bladder wall. At 1 week after viral injection, in cystometry performed under urethane anesthesia, the S4IL4-treated group did not show the intercontraction intervals reduction during intravesical administration of 10 nM resiniferatoxin (RTx). At 2 weeks after viral injection, behavioral studies were performed on vector-injected animals in an awakened state. Freezing behavior induced by 3 μM RTx, administered for 1 min into the bladder, was significantly suppressed in the S4IL4 group compared with the SHZ group. Murine IL-4 levels examined by ELISA were significantly increased in bladder and bladder afferent dorsal root ganglia at 2 weeks after viral injection. The expression of IL-1β and IL-2 and bladder inflammatory responses were significantly suppressed in the RTx-irritated bladder of S4IL4-injected rats. These results indicate that HSV vector-mediated interleukin-4 expression in the bladder and bladder afferent pathways reduces the inflammatory response, bladder overactivity and nociceptive behavior induced by bladder irritation in the rat model. Therefore, IL-4 gene therapy could be a new strategy for treating urinary frequency and/or bladder pain.

Abstract
E7820 is an orally active inhibitor of α(2)-integrin mRNA expression, currently tested in phases I and II. We aimed to evaluate what levels of inhibition of integrin expression are needed to achieve tumor stasis in mice, and to compare this to the level of inhibition achieved in humans. Tumor growth inhibition was measured in mice bearing a pancreatic KP-1 tumor, dosed at 12.5-200 mg/kg over 21 days. In the phase I study, E7820 was administered daily for 28 days over a range of 0-200 mg, followed by a 7-day washout period. PK-PD models were developed in NONMEM. α(2)-Integrin expression measured on platelets, corresponding to tumor stasis at t = 21 in 50% and 90% of the mice (I(int,50), I(int,90)) were calculated. It was evaluated if these levels of inhibition could be achieved in patients at tolerable doses. One hundred nineteen α(2)-Integrin measurements and 210 tumor size measurements were available from mice. The relationship between PK and α(2)-integrin expression was modeled using an indirect-effect model, subsequently linked to an exponential tumor growth model. I(inh,50) and I(inh,90) were 14.7% (RSE 7%) and 17.9% (RSE 8%). Four hundred sixty two α(2)-integrin measurements were available from 29 patients. Using the schedule of 100 mg qd (MTD), α(2)-integrin expression was inhibited more strongly than the I(int,50) and I(int,90) in greater than 95% and greater than 50% of patients, respectively. Moderate inhibition of α(2)-integrin expression corresponded to tumor stasis in mice, and similar levels could be reached in patients with the dose level of 100 mg qd.
