Prognostic impact of FOXF1 polymorphisms in gastric cancer patients. THE PHARMACOGENOMICS JOURNAL 2017; 18:262-269.

Abstract
A recent genome-wide association study identified seven single-nucleotide polymorphisms (SNPs) in region 16q24, near the Forkhead box-F1 (FOXF1) gene, which confer susceptibility to esophageal adenocarcinoma. We examined whether these SNPs are associated with clinical outcomes in gastric cancer (GC) patients in Japan and the United States. A total of 362 patients were included in this study: 151 Japanese GC patients treated with first-line S1 plus CDDP (training cohort) and 211 GC patients from Los Angeles County (LAC; validation cohort). Genomic DNA was isolated from whole blood or tumor tissue and analyzed by PCR-based direct DNA sequencing. Cox proportional hazard regression analyses were used to assess relationships between FOXF1 SNPs and progression-free survival (PFS) and overall survival (OS). FOXF1 rs3950627 was significantly associated with survival in both the training and validation cohorts. Japanese patients with the C/C genotype had a longer PFS (median 8.2 vs 5.3 months, hazard ratio (HR) 1.44, P=0.037) and OS (median 16.4 vs 12.2 months, HR 1.44, P=0.043) compared to patients with any A allele. Similarly, LAC patients with the C/C genotype had improved OS (3.9 vs 2.3 years, HR 1.5, P=0.022). Subgroup analyses showed these associations were specific to male patients and primary tumor subsite. Our findings suggest that FOXF1 rs3950627 might be a promising prognostic marker in GC patients.

Abstract
BACKGROUND Malignant mesothelioma is a rare but aggressive tumor, with a high misdiagnosis rate and overall bleak prognosis. In 0.7% of all cases, the origin is the pericardium. METHODS The present study is a review of the literature published in recent decades focusing on the advances in clinical manifestations, radiological findings, diagnosis, differential diagnosis, and treatment of malignant pericardial mesothelioma (MPM). RESULTS No clear relationship has been established between the etiologies and the development of MPM. Clinical symptoms and signs are nonspecific when present. The main presentations are chest pain and dyspnea. Imaging plays an important role in the detection, characterization, staging, and posttreatment follow-up. The definitive diagnosis is made on the basis of pathological findings. Chest radiography and echocardiography are common techniques used initially, but their roles are limited. Computed tomography and magnetic resonance imaging have an advantage in depicting the thickened pericardium, mediastinal lymph node, tumor, and the extension of adjacent structures. Surgery is the most important treatment modality and remains palliative in most cases, while the roles of chemo- and radiotherapy are unsatisfactory. CONCLUSION Clinical trials of malignant pleural and peritoneal mesothelioma remain important for MPM management. Multimodality treatment of surgery, chemotherapy, radiotherapy, and immunotherapy is expected to have a role in the treatment of MPM.

Abstract
BACKGROUND AND PURPOSE Pancreatic cancer is a solid tumour that is often fatal. Hence, there is an urgent need to identify new drug targets for this disease. Highly proliferating cancer cells have an increased demand for nutrients and, therefore, need to up-regulate selective amino acid transporters. Here, we investigated which amino acid transporters are up-regulated in pancreatic cancer and whether any of these transporters has potential as a drug target for this fatal disease. EXPERIMENTAL APPROACH The expression of amino acid transporters in pancreatic cancer was analysed using publicly available microarray datasets, and the findings with the transporter SLC6A14 were validated by mRNA and protein analysis. The potential of SLC6A14 as a drug target was evaluated using a pharmacological blocker in vitro and in vivo. KEY RESULTS SLC6A14 was up-regulated several fold in patient-derived xenografts, primary tumour tissues and pancreatic cancer cells lines compared to normal pancreatic tissue or normal pancreatic epithelial cells. The magnitude of the up-regulation of SLC6A14 was the highest among the amino acid transporters examined. A pharmacological blocker of SLC6A14, α-methyltryptophan, induced amino acid starvation in pancreatic cancer cells and reduced the growth and proliferation of these cells, both in vitro and in vivo. CONCLUSION AND IMPLICATIONS The salient features of this study are that SLC6A14 is markedly up-regulated in pancreatic cancer and that pharmacological blockade of this transporter interferes with amino acid nutrition and reduces growth and proliferation of pancreatic cancer cells. These findings identify SLC6A14 as a novel druggable target for pancreatic cancer.

Abstract
The scanning tunnelling microscope (STM) may be used as a low-energy, electrical nanosource of surface plasmon polaritons and light. In this article, we demonstrate that the optimum mode of operation of the STM for maximum photon emission is completely different in air than in vacuum. To this end, we investigate the emission of photons, the variation in the relative tip-sample distance and the measured current as a function of time for an STM operating in air. Contrary to the case of an STM operating in vacuum, the measured current between the tip and sample for an STM in air is very unstable (rapidly fluctuating in time) when the applied voltage between the tip and sample is in the ∼1.5-3 V range (i.e., in the energy range of visible photons). The photon emission occurs in short (50 μs) bursts when the STM tip is closest to the sample. The current instabilities are shown to be a key ingredient for producing intense light emission from an STM operating in air (photon emission rate several orders of magnitude higher than for stable current). These results are explained in terms of the interplay between the tunnel current and the electrochemical current in the ubiquitous thin water layer that exists when working in air.

Abstract
We report the first measurement of the flux-averaged cross section for charged current coherent π^{+} production on carbon for neutrino energies less than 1.5 GeV, and with a restriction on the final state phase space volume in the T2K near detector, ND280. Comparisons are made with predictions from the Rein-Sehgal coherent production model and the model by Alvarez-Ruso et al., the latter representing the first implementation of an instance of the new class of microscopic coherent models in a neutrino interaction Monte Carlo event generator. We observe a clear event excess above background, disagreeing with the null results reported by K2K and SciBooNE in a similar neutrino energy region. The measured flux-averaged cross sections are below those predicted by both the Rein-Sehgal and Alvarez-Ruso et al.

Abstract
The Hippo pathway is involved in colorectal cancer (CRC) development and progression. The Hippo regulator Rassf1a is also involved in the Ras signaling cascade. In this work, we tested single nucleotide polymorphisms within Hippo components and their association with outcome in CRC patients treated with cetuximab. Two cohorts treated with cetuximab plus chemotherapy were evaluated (198 RAS wild-type (wt) patients treated with first-line FOLFIRI plus Cetuximab within the FIRE-3 trial and 67 Ras wt patients treated either with first-line mFOLFOX6 or SOX plus Cetuximab). In these two populations, Rassf1a rs2236947 was associated with overall survival, as patients with a CC genotype had significantly longer OS compared to those with CA or AA genotypes. This association was stronger in patients with left-side CRC [HR: 1.79 (1.01–3.14); P=0.044 and HR: 2.83 (1.14–7.03); P=0.025, for Fire 3 and JACCRO cohorts, respectively]. Rassf1a rs2236947 is a promising biomarker for patients treated with cetuximab plus chemotherapy.

Abstract
In certain regions of the United States in which organ donor shortages are persistent and competition is high, recipients wait longer and are critically ill with Model for End-Stage Liver Disease (MELD) scores ≥40 when they undergo liver transplantation. Recent implementation of Share 35 has increased the percentage of recipients transplanted at these higher MELD scores. The purpose of our study was to examine national data of liver transplant recipients with MELD scores ≥40 and to identify risk factors that affect graft and recipient survival. During the 12-year study period, 5002 adult recipients underwent deceased donor whole-liver transplantation. The 1-, 3-, 5- and 10-year graft survival rates were 77%, 69%, 64% and 50%, respectively. The 1-, 3-, 5- and 10-year patient survival rates were 80%, 72%, 67% and 53%, respectively. Multivariable analysis identified previous transplant, ventilator dependence, diabetes, hepatitis C virus, age >60 years and prolonged hospitalization prior to transplant as recipient factors increasing the risk of graft failure and death. Donor age >30 years was associated with an incrementally increased risk of graft failure and death. Recipients after implementation of Share 35 had shorter waiting times and higher graft and patient survival compared with pre-Share 35 recipients, demonstrating that some risk factors can be mitigated by policy changes that increase organ accessibility.

Abstract
T2K reports its first measurements of the parameters governing the disappearance of ν[over ¯]_{μ} in an off-axis beam due to flavor change induced by neutrino oscillations. The quasimonochromatic ν[over ¯]_{μ} beam, produced with a peak energy of 0.6 GeV at J-PARC, is observed at the far detector Super-Kamiokande, 295 km away, where the ν[over ¯]_{μ} survival probability is expected to be minimal. Using a data set corresponding to 4.01×10^{20} protons on target, 34 fully contained μ-like events were observed. The best-fit oscillation parameters are sin^{2}(θ[over ¯]_{23})=0.45 and |Δm[over ¯]_{32}^{2}|=2.51×10^{-3} eV^{2} with 68% confidence intervals of 0.38-0.64 and 2.26-2.80×10^{-3} eV^{2}, respectively. These results are in agreement with existing antineutrino parameter measurements and also with the ν_{μ} disappearance parameters measured by T2K.

Abstract
PURPOSE Telomere shortening occurs in tumor tissues and peripheral blood lymphocytes of many common human malignancies, including lung cancer, but its variation in T-cells has never been investigated. Thus, the aim of this study was to assess telomere length in T-cells and its correlation with the clinical characteristics of patients with lung cancer. PATIENTS AND METHODS A total of 40 patients with lung cancer but without prior cancer history and 25 healthy individuals were selected. T-cells were isolated and their telomere lengths were measured using quantitative real-time polymerase chain reaction methods. RESULTS Telomere length in T-cells was significantly shorter in patients with lung cancer than in controls (P<0.001). Shorter telomere length was significantly associated with increased clinical stage (P=0.008) and distant metastasis (P=0.028). Naïve T-cells from patients with lung cancer had significantly decreased telomere length when compared with those from controls (P=0.012). CONCLUSION The shortened telomere length in T-cells occurred in naïve T-cells and might be related to lung cancer progression.

Abstract
In certain regions of the United States in which organ donor shortages are persistent and competition is high, recipients wait longer and are critically ill with Model for End-Stage Liver Disease (MELD) scores ≥40 when they undergo liver transplantation. Recent implementation of Share 35 has increased the percentage of recipients transplanted at these higher MELD scores. The purpose of our study was to examine national data of liver transplant recipients with MELD scores ≥40 and to identify risk factors that affect graft and recipient survival. During the 12-year study period, 5002 adult recipients underwent deceased donor whole-liver transplantation. The 1-, 3-, 5- and 10-year graft survival rates were 77%, 69%, 64% and 50%, respectively. The 1-, 3-, 5- and 10-year patient survival rates were 80%, 72%, 67% and 53%, respectively. Multivariable analysis identified previous transplant, ventilator dependence, diabetes, hepatitis C virus, age >60 years and prolonged hospitalization prior to transplant as recipient factors increasing the risk of graft failure and death. Donor age >30 years was associated with an incrementally increased risk of graft failure and death. Recipients after implementation of Share 35 had shorter waiting times and higher graft and patient survival compared with pre-Share 35 recipients, demonstrating that some risk factors can be mitigated by policy changes that increase organ accessibility.

Abstract
To explore the need for rescue intracytoplasmic sperm injection (ICSI) in cases of partial fertilisation failure during a conventional in vitro fertilisation cycle, rescue ICSI was performed for cycles with a fertilisation rate of <50%. The data were divided into three groups based on the fertilisation rate: group 1 (0%), group 2 (<25%) and group 3 (>25%). The impact of rescue ICSI on each group was then analysed in terms of ovum fertilisation, embryo development, embryo utilisation and selection of embryos for transfer. Rescue ICSI was performed on 1831 unfertilised oocytes from 313 cycles. The fertilisation rates for group 1, group 2 and group 3 were 74.66, 68.35 and 65.46%, and the rate of polyploidy in the three groups was 8.55, 11.33, and 14.47%. The percentage of embryos that can be transferred from rescue ICSI for group 2 was 38.33%, and this value was higher than those of the other two groups. It is concluded that rescue ICSI is not recommended for patients with an IVF rate of >25% as the procedure is associated with a greater risk and low returns. However, it is feasible to perform rescue ICSI for patients with IVF rates of <25%.

Abstract
BACKGROUND This randomized clinical study was conducted to evaluate the therapeutic benefits of cytokine-induced killer (CIK) cell immunotherapy in combination with chemotherapy in metastatic colorectal cancer (mCRC) patients. PATIENTS AND METHODS Sixty-one patients in group 1 (cell therapy group) received autologous CIK cell immunotherapy in combination with chemotherapy (5-Fluorouridine, leucovorin and oxaliplatin [FOLFOX4] plan). Another 61 patients in group 2 (the control group) received chemotherapy (FOLFOX4 plan) alone. The primary study end points were overall survival (OS) and progression-free survival (PFS). The secondary end points were treatment response and adverse events. RESULTS The 3-year PFS and OS in group 1 were 20% and 48%, respectively, compared with 13% and 23%, respectively, in group 2 (P = .131 and P < .001, respectively). The median OS in group 1 was significantly increased compared with that in group 2 (OS, 36 vs. 16 months; P < .001). Furthermore, there was a trend toward superior PFS in group 1 compared with that in group 2 (PFS, 16 vs. 10 months; P = .072). Using univariate analysis, we found that Karnofsky performance status <80, number of metastases >1, and increased platelet levels were significantly associated with poorer prognosis in group 1. Alternatively, the cycle count of CIK cell treatment was significantly associated with good prognosis in group 1. Toxicity was mild in patients who received CIK therapy. CONCLUSION This study shows that CIK cell immunotherapy in combination with chemotherapy is well tolerated and improves the OS of mCRC patients.

Abstract
The present study investigated the genetic characterization of red-colored heartwood Chinese fir [Cunninghamia lanceolata (Lamb.) Hook.] in Guangxi using 21 simple sequence repeat (SSR) markers and analyzes of the genetic variation (N = 149) in samples obtained from five sites in Guangxi Province, China. The number of different alleles and the Shannon's information index per locus ranged from 3 to 12 and from 0.398 to 2.258 with average values of 6 and 1.211, respectively, indicating moderate levels of genetic diversity within this germplasm collection. The observed and expected heterozygosity ranged from 0.199 to 0.827 and from 0.198 to 0.878 with an average of 0.562 and 0.584, respectively. Although, the mean fixation index was 0.044, indicative of a low level of genetic differentiation among germplasms, analysis of molecular variance revealed considerable differentiation (99%) within the samples. The neighbor-joining dendrogram revealed that the majority of red-colored Chinese fir genotypes were apparently not associated with their geographic origins. Further analysis by STRUCTURE showed that this Guangxi germplasm collection could be divided into three genetic groups comprising 76, 37, and 36 members, respectively; these were classified into mixed groups with no obvious population structure. These results were consistent with those of the cluster analysis. On the whole, our data provide a starting point for the management and conservation of the current Guangxi germplasm collection as well as for their efficient use in Chinese fir-breeding programs.

[PMID: 26416897 DOI: 10.1093/annonc/mdv474] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2015] [Accepted: 09/18/2015] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Tumor-associated macrophages (TAMs) with the M2-like phenotype are regulated by mainly NF-kB pathway including TBK1, which can influence tumor progression by secretion of proangiogenic factors such as vascular endothelial growth factor. The CCL2/CCR2 axis, histidine-rich glycoprotein (HRG), and placenta growth factor (PIGF) play a critical role in the polarization of M1/M2 phenotypes and the recruitment of TAMs to tumor microenvironment. We therefore hypothesized that variations in genes involved in regulating TAMs may predict clinical outcomes of bevacizumab treatment in patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS We analyzed genomic DNA extracted from samples of patients receiving bevacizumab plus FOLFIRI as a first-line treatment using PCR-based direct sequencing. Twelve functional single-nucleotide polymorphisms in eight genes (CCL2, CCR2, HRG, PIGF, NFKB1, TBK1, CCL18, and IRF3) were tested for associations with clinical outcomes in a discovery cohort of 228 participants in TRIBE trial (NCT00719797), then validated in 248 KRAS exon2 (KRAS) wild-type participants in FIRE3 trial (NCT00433927). FIRE3-cetuximab cohort served as a negative control. RESULTS TBK1 rs7486100 was significantly associated with overall survival in 95 KRAS wild-type patients of TRIBE cohort in univariate analysis and had a strong trend in multivariable analysis; furthermore, the association of the T allele was observed for progression-free survival (PFS) in both univariate and multivariable analyses in FIRE3-bevacizumab but not cetuximab cohort. CCL2 rs4586, CCL18 rs14304, and IRF3 rs2304205 had univariate and multivariable correlations with PFS in KRAS mutant patients of the TRIBE cohort, whereas they had no correlations in KRAS wild-type patients of the TRIBE cohort. No association was seen in control cohort. CONCLUSIONS Our study demonstrates for the first time that variations in genes regulating TAMs-related functions are significantly associated with clinical outcomes in mCRC patients treated with bevacizumab-containing chemotherapy. These results also suggest that some TAM-related gene variations may predict outcomes of bevacizumab treatment in KRAS status-dependent manner.

Abstract
Historically, the pivotal role of B cells or B lymphocytes in immunity has been attributed to the production of antibodies. They were also demonstrated to present antigens to T cells and to secrete cytokines, thereby acting as positive regulators in immune responses. A series of studies on autoimmune diseases, however, led researchers to find a unique subset of B cells, later described as "regulatory B cells" (Bregs), that has the ability to suppress immune responses. Bregs occur not only in autoimmune diseases, but also in inflammation and transplantation. Furthermore, recently published literatures suggested that Bregs contributed to the growth and metastasis of certain cancers. In this review, we will discuss these unique subsets of B cells in different kinds of disorders, with particular emphasis on the mechanisms of their immunoregulatory role that were collected from mice and humans.

Abstract
Objective A meta-analysis was performed to augment the insufficient data on the impact of mutative EGFR downstream phosphatidylinositol-3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) pathways on the clinical efficiency of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment of non-small cell lung cancer (NSCLC) patients. Methods Network databases were explored in April, 2015. Papers that investigated the clinical outcomes of NSCLC patients treated with EGFR-TKIs according to the status of K-ras and/or PIK3CA gene mutation were included. A quantitative meta-analysis was conducted using standard statistical methods. Odds ratios (ORs) for objective response rate (ORR) and hazard ratios (HRs) for progression-free survival (PFS) and overall survival (OS) were calculated. Results Mutation in K-ras significantly predicted poor ORR [OR =0.22; 95% confidence interval (CI), 0.13-0.35], shorter PFS (HR =1.56; 95% CI, 1.27-1.92), and shorter OS (HR =1.59; 95% CI, 1.33-1.91) in NSCLC patients treated with EGFR-TKIs. Mutant PIK3CA significantly predicted shorter OS (HR =1.83; 95% CI, 1.05-3.20), showed poor ORR (OR =0.70; 95% CI, 0.22-2.18), and shorter PFS (HR =1.79; 95% CI, 0.91-3.53) in NSCLC patients treated with EGFR-TKIs. Conclusion K-ras mutation adversely affected the clinical response and survival of NSCLC patients treated with EGFR-TKIs. PIK3CA mutation showed similar trends. In addition to EGFR, adding K-ras and PIK3CA as routine gene biomarkers in clinical genetic analysis is valuable to optimize the effectiveness of EGFR-TKI regimens and identify optimal patients who will benefit from EGFR-TKI treatment.

Abstract
IMP3 (insulin-like growth factor-2 mRNA binding protein 3) is an oncofetal protein whose expression is prognostic for poor outcome in several cancers. Although IMP3 is expressed preferentially in triple-negative breast cancer (TNBC), its function is poorly understood. We observed that IMP3 expression is significantly higher in tumor initiating than in non-tumor initiating breast cancer cells and we demonstrate that IMP3 contributes to self-renewal and tumor initiation, properties associated with cancer stem cells (CSCs). The mechanism by which IMP3 contributes to this phenotype involves its ability to induce the stem cell factor SOX2. IMP3 does not interact with SOX2 mRNA significantly or regulate SOX2 expression directly. We discovered that IMP3 binds avidly to SNAI2 (SLUG) mRNA and regulates its expression by binding to the 5' UTR. This finding is significant because SLUG has been implicated in breast CSCs and TNBC. Moreover, we show that SOX2 is a transcriptional target of SLUG. These data establish a novel mechanism of breast tumor initiation involving IMP3 and they provide a rationale for its association with aggressive disease and poor outcome.

Abstract
Platinum-induced myelosuppression severely impedes successful chemotherapy in non-small-cell lung cancer (NSCLC) patients. Hence, it is clinically important to identify the patients who are at high risk for severe toxicity to certain chemotherapy. We first carried out a genome-wide scan of 906 703 single-nucleotide polymorphisms (SNPs) to identify genetic variants associated with platinum-induced myelosuppression risk in 333 NSCLC patients with chemotherapy. Then, we replicated 24 SNPs that had P<1 × 10(-4) in another independent cohort of 876 NSCLC patients. With P<0.05 as the criterion of statistical significance, we found that rs13014982 at 2q24.3 and rs9909179 at 17p12 exhibited consistently significant associations with myelosuppression risk in both the genome-wide association studies (GWAS) scan and the replication stage (rs13014982: odds ratio (OR)=0.55, 95% confidence intervals (CIs): 0.41-0.74, P=7.29 × 10(-5) for GWAS scan and OR=0.77, 95% CI: 0.65-0.93, P=0.006 for replication stage; rs9909179: OR=0.51, 95% CI: 0.37-0.70, P=4.60 × 10(-5) for GWAS scan and OR=0.82, 95% CI: 0.68-0.99, P=0.040 for replication stage; both in additive model). In combined samples of genome-wide scan and replication samples, the minor alleles of rs13014982 and rs9909179 remained significant associations with the decreased risk of myelosuppression (rs13014982: OR=0.71, 95% CI: 0.61-0.83, P =1.36 × 10(-5); rs9909179: OR=0.76, 95% CI: 0.65-0.89, P=0.001). Rs13014982 at 2q24.3 and rs9909179 at 17p12 might be independent susceptibility markers for platinum-induced myelosuppression risk in NSCLC patients.

Abstract
Blindness due to retinal degeneration affects millions of people worldwide, but many disease-causing mutations remain unknown. PNPLA6 encodes the patatin-like phospholipase domain containing protein 6, also known as neuropathy target esterase (NTE), which is the target of toxic organophosphates that induce human paralysis due to severe axonopathy of large neurons. Mutations in PNPLA6 also cause human spastic paraplegia characterized by motor neuron degeneration. Here we identify PNPLA6 mutations in childhood blindness in seven families with retinal degeneration, including Leber congenital amaurosis and Oliver McFarlane syndrome. PNPLA6 localizes mostly at the inner segment plasma membrane in photoreceptors and mutations in Drosophila PNPLA6 lead to photoreceptor cell death. We also report that lysophosphatidylcholine and lysophosphatidic acid levels are elevated in mutant Drosophila. These findings show a role for PNPLA6 in photoreceptor survival and identify phospholipid metabolism as a potential therapeutic target for some forms of blindness.

Abstract
BACKGROUND Nuclear factor-kappaB (NF-κB) and CCL2/CCR2 chemokine axis play a central role in tumor progression such as stimulation of angiogenesis, acceleration of tumor invasion and migration, and suppression of innate immunosurveillance in the macrophage-related functions. There have been few reports regarding association of the macrophage function-related genes with the clinical outcome in gastric cancer. We hypothesized that variants in genes encoding for NF-κB and CCL2/CCR2 axis may predict prognosis in gastric cancer and tested whether the functional single-nucleotide polymorphisms (SNPs) will be associated with clinical outcome in patients with gastric cancer across two independent groups. PATIENTS AND METHODS This study enrolled two cohorts which consisted of 160 Japanese patients and 104 US patients with locoregional gastric cancer. Genomic DNA was analyzed for association of 11 SNPs in NFKB1, RELA, CCL2, and CCR2 with clinical outcome using PCR-based direct DNA sequencing. RESULTS The univariable analysis showed four SNPs had significant association with clinical outcome in the Japanese cohort, NFKB1 rs230510 remained significant upon multivariable analysis. The patients with the A allele of the NFKB1 rs230510 had significantly longer overall survival (OS) compared with those with the T/T genotype in both the Japanese and US cohort in the univariable analysis. In contrast, genotypes with the T allele of CCL2 rs4586 were significantly associated with shorter OS compared with the C/C genotype in the US cohort [hazard ratio (HR) 2.43; P = 0.015] but longer OS in the Japanese cohort (HR 0.58; P = 0.021), resulting in the statistically significant opposite impact on OS (P = 0.001). CONCLUSIONS Our study provides the first evidence that the NFKB1 rs230510 and CCL2 rs4586 are significantly associated with the clinical outcome in patients with locoregional gastric cancer. These results also suggest that the genetic predisposition of the host may dictate the immune-related component of the tumor for progression in gastric cancer.

Abstract
Research indicates that using a cell phone to talk or text while maneuvering a vehicle impairs driving performance. However, few published studies directly compare the distracting effects of texting using a hands-free (i.e., speech-based interface) versus handheld cell phone, which is an important issue for legislation, automotive interface design and driving safety training. This study compared the effect of speech-based versus handheld text entries on simulated driving performance by asking participants to perform a car following task while controlling the duration of a secondary text-entry task. Results showed that both speech-based and handheld text entries impaired driving performance relative to the drive-only condition by causing more variation in speed and lane position. Handheld text entry also increased the brake response time and increased variation in headway distance. Text entry using a speech-based cell phone was less detrimental to driving performance than handheld text entry. Nevertheless, the speech-based text entry task still significantly impaired driving compared to the drive-only condition. These results suggest that speech-based text entry disrupts driving, but reduces the level of performance interference compared to text entry with a handheld device. In addition, the difference in the distraction effect caused by speech-based and handheld text entry is not simply due to the difference in task duration.

Abstract
The aim of the study was to investigate and compare the clinical manifestations between HLA-B27(+) and HLA-B27(-) ankylosing spondylitis (AS) patients in order to obtain knowledge of the impact of HLA-B27 status on AS, and to inform clinical treatment. A nationwide epidemiological investigation was performed from November 2008 to October 2010. The demographic data and clinical characteristics, and the status of HLA-B27 were collected using questionnaires and laboratory assay, respectively. A total of 2144 patients (78.5% males and 78.4% HLA-B27(+) AS patients) participated in this study. The percentages of males, patients with family history, and involvement of lumbar spine, thoracic spine and hip joints, were observed to be significantly higher in the HLA-B27(+) AS patients than in their HLA-B27(-) AS peers.

Abstract
Telomeres are specific nucleoprotein structures at the end of a eukaryotic chromosomes characterized by repeats of the sequence TTAGGG and regulated by the enzyme telomerase which prevents their degradation, loss, rearrangement and end-to-end fusion. During activation, T lymphocytes actively divide, albeit through only a finite number of cell divisions due to shortening of telomeres. However, studies have demonstrated that human telomerase reverse transcriptase (hTERT), thought to be the major component regulating telomerase activity, can enhance the proliferation of T cells when overexpressed. There are many treatments for cancers, most of which are targeting the telomere and telomerase of tumor cells. However, the hTERT-transduced T cells improve their potential for proliferation, making them an appropriate cell resource for tumor adoptive immunotherapy, a procedure whereby T cells are isolated from patients, expanded ex vivo and eventually delivered back into the patients, provides a new approach for tumor therapy through improved overall survival rates in cancer patients. In this review, we will focus on the telomerase activity in T cells, the regulation of telomerase activity, and hTERT-transduced T cells used in adoptive immunotherapy for cancer.

Abstract
Anesthesia is a loss of sensation or consciousness and mechanisms by which drugs can produce this state are not clear. Recent studies gave insight show anesthetic agents may lead to loss of consciousness at the molecular level. The objective of this study was to determine whether ropivacaine can influence antioxidant defense system.To analyze the response of the antioxidant defense system to ropivacaine samples were taken from the vein before anesthesia (0 min) and 5 min, 15 min, and 60 min after anesthesia. Subsequently, the levels of lipid peroxidation as melaninedialdehyde (MDA) and glutathione (GSH), as well as superoxide dismutase (SOD) and catalase (CAT) activities were measured.We observed moderate increase in lipid peroxidation and glutathione levels. More-over, the activity of superoxide dismutase was slightly enhanced. These alterations occurred 5 min after spinal injection of ropivacaine and this phenomenon was maintained throughout anesthesia. We measured decreased catalase activity starting from 5 min after anesthesia and activity of this antioxidant enzyme was not recovered even after 60 min of anesthesia.We found that spinal injection of ropivacaine results in increased levels of free radicals in spinal fluid, which may stimulate antioxidant defense system of spinal fluid during anesthesia.

Abstract
Premembrane (prM) and envelope (E) proteins, the major structural proteins of Japanese encephalitis virus (JEV) each contain single potential N-glycosylation site. In this study, the role of N-glycosylation of these proteins on their folding and activity were investigated. Three mutant prM and/or E (prM-E) genes lacking N-glycosylation sites were generated by site-directed mutagenesis. The effects of the N-glycan on folding, secretion and cytotoxicity of mutant proteins were determined by comparison with their wild type (wt) counterparts. Removal of N-glycan from the prM protein resulted in a complete misfolding of the E protein and failure to form virus-like particles (VLPs). A similar removal of N-glycan from the E protein led to a low efficiency of its folding and VLPs formation. The secretion and cytotoxicity of the E protein was also markedly impaired in case the glycosylation sites in the prM or E or both proteins were removed. These results suggest that the N-glycosylation of the prM protein is critical to the folding of the E protein, which makes it pivotal in the cytotoxicity of JEV particles and their production.

Abstract
PURPOSE This prospective study aims to explore the benefit of cytokine-induced killer cell (CIK) treatment in hepatocellular carcinoma patients, which has not yet been thoroughly studied before. METHODS From January 2004 to May 2009, 132 patients who were initially diagnosed with hepatocellular carcinoma of Barcelona Clinic Liver Cancer (BCLC) stage A, B or C, Child-Pugh scores of A or B and without prior treatment were enrolled in the study. Patients were randomly assigned to either arm 1 (n = 66) to receive CIK treatment plus standard treatment, or arm 2 (n = 66) to receive standard treatment only. The primary end point was overall survival (OS) and the secondary endpoint was progression-free survival as evaluated by Kaplan-Meier analyses and treatment hazard ratios with the Cox proportional hazards model. RESULTS The 1-year (OS: 74.2% vs. 50.0%, 95% CI: 63.6-84.8% vs. 37.8-62.2, p = 0.002), 2-year (OS: 53.0% vs. 30.3%, 95% CI: 40.8-65.2% vs. 19.1-41.5%, p = 0.002), 3-year (OS: 42.4% vs. 24.2%, 95% CI: 30.4-54.4% vs. 13.8-34.6%, p = 0.005) and median overall and progression-free survivals of arm 1 patients were significantly higher than those of arm 2. Therefore, in patients who are not suitable for surgery, significant benefit is obtained from CIK treatment. The main adverse effects of CIK included fever, allergy and headache pain. CONCLUSIONS Hepatocellular carcinoma patients who were not suitable for surgery demonstrate prolonged overall and progression-free survival from CIK treatment.

Abstract
Dendritic cells (DCs) have traditionally been viewed as constituting an 'information management' system that functions solely to integrate a diverse array of incoming signals, in order to induce immune reactivity. In recent years, however, there has been a shift towards viewing these cells as key regulators in the orchestration of immunological tolerance, with increasing recognition that they are capable of suppressing T-cell responses depending on signalling processes and localised biochemical conditions. Indoleamine 2,3-dioxygenase (IDO) competent (IDO⁺) DCs are a subset of human DCs which are programmed to a tolerogenic state and play a vital role in establishing and maintaining a tumour-suppressing milieu. The expression of IDO in these DCs represents a key mechanism responsible for inducing the tolerogenic state. However, the mechanisms by which IDO becomes dysregulated in this subset of DCs have not yet been described. In this review, the function of IDO⁺ DCs within the cancer-tolerogenic milieu, as well as the signals responsible for expression of IDO in this subset, will be discussed.

Abstract
BACKGROUND The relationship between body mass index (BMI) and long-term outcome in gastric cancer patients following radical gastrectomy continues to be debated. We investigated the association between BMI, clinicopathological features, and prognosis in Chinese gastric carcinoma patients. METHODS A retrospective consecutive cohort study was performed on 1,296 patients who underwent gastrectomy with curative intent at the Tianjin Cancer Institute Hospital between 1999 and 2004. The clinicopathological characteristics, overall 5-year survival rate (OS), and preoperative and six-month postoperative BMIs of both overweight (BMI ≥ 25 kg/m(2); H-BMI; n = 364) and non-overweight (BMI <25 kg/m(2); N-BMI; n = 932) patients were compared. RESULTS Among these patients, 364 (28.1 %) were overweight. The OS was significantly higher in the H-BMI than N-BMI group (33.2 vs. 24.1 %, respectively; p < 0.001). Preoperative and six-month postoperative BMIs were 27.1 ± 2.0 and 24.8 ± 2.0 kg/m(2), respectively, in the H-BMI group (p < 0.001), whereas they were 21.7 ± 2.2 and 20.7 ± 2.2 kg/m(2), respectively, in the N-BMI group (p = 0.007). There was significantly better differentiation (p = 0.034), less distant metastases (p = 0.006), and a lower metastatic lymph node ratio (p = 0.014) observed in the H-BMI groups. Multivariate analyses indicated age, BMI, pathological tumor depth, distant metastases, metastatic lymph node ratio, and tumor size as independent prognostic factors. CONCLUSIONS Our findings suggest that overweight patients were less likely to have tumors with aggressive features and can achieve ideal body weight following curative gastrectomy, possibly resulting in better long-term prognosis.

Abstract
Ulva prolifera, an intertidal macroalga, has to adapt to wide variations in light intensity, making this species particularly rewarding for studying the evolution of photoprotective mechanisms. Intense light induced increased non-photochemical quenching (NPQ) and stimulated de-epoxidation of xanthophyll cycle components, while DTT-treated samples had lower NPQ capacity, indicating that the xanthophyll cycle must participate in photoprotection. In this work, we found that the PsbS-related NPQ was maintained in U. prolifera. According to analysed gene expression, both LhcSR and psbS were up-regulated in high light, suggesting that these two genes are light-induced. LHCSR and PsbS proteins were present at different light intensities and accumulated under high light conditions, and PsbS concentrations were higher than LHCSR, showing that the NPQ mechanism of U. prolifera is more dependent on PsbS protein concentration. Moreover, the level of both LHCSR and PsbS proteins was high even in the darkness, and neither the transcript level nor protein content of LhcSR and psbS genes varied significantly following short-term exposure to intense light. These findings suggest that this alga can modulate NPQ levels through regulation of the xanthophyll cycle and concentrations of PsbS and/or LHCSR.
