Abstract
Flavonoids have been reported to inhibit tumor growth by causing cell cycle arrest. However, little is known about the direct targets of flavonoids in tumor growth inhibition. In the present study, we developed a novel method using magnetic FG beads to purify flavonoid-binding proteins, and identified ribosomal protein S9 (RPS9) as a binding partner of the flavonoid apigenin. Similar to treatment with apigenin, knockdown of RPS9 inhibited the growth of human colon cancer cells at the G2/M phase by downregulating cyclin-dependent kinase 1 (CDK1) expression at the promoter level. Furthermore, knockdown of RPS9 suppressed G2/M arrest caused by apigenin. These results suggest that apigenin induces G2/M arrest at least partially by directly binding and inhibiting RPS9 which enhances CDK1 expression. We therefore raise the possibility that identification of the direct targets of flavonoids may contribute to the discovery of novel molecular mechanisms governing tumor growth.

Abstract
e15531 Background: Interstitial lung disease (ILD) is one of the adverse events during treatment with everolimus for metastatic renal cell carcinoma (mRCC). Japanese study of everolimus treatment-associated ILD as a prognostic factor is rare. Methods: We retrospectively assessed the incidence and outcome of ILD in mRCC patients treated with everolimus. Between April 2010 and August 2012, 25 cases were treated with everolimus after the failure of one or two TKIs in our institute. All adverse events were graded in accordance with NCI CTCAE, version 3.0. Results: A total of 25 patients received treatment with everolimus and included 18 male and 7 female patients ranging in age from 21 to 84 years (median 62). According to MSKCC risk criteria, 6 cases were at favorable risk, 16 cases were at intermediate risk, and 3 cases were at poor risk. The median treatment term was 4 months (range 2-17 months). SD was reported in 19 cases and PD in 6 cases. Progression free survival was 3.5 months and overall survival was 12 months. ILD was found in 7 cases (28%). One was G1, five were G2, and one was G3. Corticosteroid therapy was initiated in 3 cases. In 5 of 7 ILD cases, everolimus was re-challenged. In our series, patients with ILD showed significantly better progression free survival than those without ILD (PFS was 8 months vs 3 months. Log-rank, P<0.001). There were no significant differences between the two groups in overall survival (12 months in patients with ILD vs 10 months in patients without ILD. Log-rank, NS). Conclusions: Everolimus appears to have been effective and well-tolerated in our institute. Re-challenge with everolimus was feasible after improving everolimus-induced ILD in cases of grade 1-2. To confirm these findings, the efficacy and AE profile of everolimus in Japanese patients should be investigated.

Abstract
Abstract
Purpose: Nitric oxide (NO) is a versatile signaling molecule. Its roles in a variety of physiological functions in mammals are beginning to be understood. It has been demonstrated that NO up-regulates the expression of the Fas receptor on human tumor cells via specific inactivation of transcription repressor YY1 DNA binding activity to the silencer region of the Fas promoter (Hermes G., et al. 2001). We also showed that inactivation of YY1 via protein S-nitrosylated by NO in prostatic cancer could be identified (Hongo F., et al. 2005). This post-translational modification, known as S-nitrosylation, has emerged as a highly conserved and spatiotemporally specific signaling mechanism. The objective of our study was to examine the effect of NO donor treatment on renal cell cancer.
Methods: We examined the effect of the NO donor DETA-NONOate (100-500uM) on the following renal cell cancer cell lines; CAKI-1, NC65, and ACHN. Anti-S-nitroso-Cysteine antibody in the rabbit (SIGMA-ALDRICH) was applied as a primary antibody for immunohistochemistry. The biotin-switch technique was applied to detect specific S-nitrosylated proteins. Whole cell lysates were extracted from ACHN cells employed with DETA-NONOate. Using an S-nitrosylated detection kit (Cayman Chemical Company), S-NO was replaced by Biotin. Cell lysates were incubated at 4 oC with 30 μL of Dynabeads M-280 Streptavidin (Invitrogen) for 3 hrs. After five washes with wash buffer (S-Nitrosylation Wash buffer), the protein complex was eluted from anti-biotin dynabeads by incubation with 1x volume of elution buffer (0.1M glycine (pH2.0)) twice for 15 min. Each sample was added to an SDS-polyacrylamide gel for mass spectrometry.
Results: Significant up-regulation of S-nitrosylated proteins employed with DETA-NONOate was observed by immunohistochemistry. Specific S-nitrosylated proteins in ACHN cells were detected by the biotin-switch technique and included HSP90 (heat shock protein 90), GRP78 (HSP70 family), HSP70, and pyruvate kinase M2.
Conclusions: Our data showed that NO treatment significantly increased S-nitrosylation of several proteins. S-nitrosylation should be considered as one of the mechanisms by which NO acts on cancer cells.

Abstract
Apo2 ligand (Apo2L)/tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising cancer therapeutic agent. Recombinant human Apo2L/TRAIL has been under clinical trials, whereas various kinds of malignant tumors have resistance to Apo2L/TRAIL. We and others have shown that several anticancer agents and flavonoids overcome resistance to Apo2L/TRAIL by upregulating death receptor 5 (DR5) in malignant tumor cells. However, the mechanisms by which these compounds induce DR5 expression remain unknown. Here we show that the dietary flavonoid apigenin binds and inhibits adenine nucleotide translocase-2 (ANT2), resulting in enhancement of Apo2L/TRAIL-induced apoptosis by upregulation of DR5. Apigenin and genistein, which are major flavonoids, enhanced Apo2L/TRAIL-induced apoptosis in cancer cells. Apigenin induced DR5 expression, but genistein did not. Using our method identifying the direct targets of flavonoids, we compared the binding proteins of apigenin with those of genistein. We discovered that ANT2 was a target of apigenin, but not genistein. Similarly to apigenin, knockdown of ANT2 enhanced Apo2L/TRAIL-induced apoptosis by upregulating DR5 expression at the post-transcriptional level. Moreover, silencing of ANT2 attenuated the enhancement of Apo2L/TRAIL-induced apoptosis by apigenin. These results suggest that apigenin upregulates DR5 and enhances Apo2L/TRAIL-induced apoptosis by binding and inhibiting ANT2. We propose that ANT2 inhibitors may contribute to Apo2L/TRAIL therapy.

Abstract
PURPOSE The pretreatment C-reactive protein (CRP) level is reported to be a prognostic indicator in patients with hepatocellular carcinoma (HCC). METHODS We investigated the prognostic implications of the changes in the CRP level after initial treatment in patients with HCC. We prospectively evaluated a cohort of 150 patients with newly diagnosed HCC. The patients were categorized into three groups: group 1 (n = 120) with pre- and post-treatment CRP <1.0 mg/dl, group 2 (n = 5) with pre-treatment CRP ≥1.0 mg/dl and post-treatment CRP <1.0 mg/dl, and group 3 (n = 25) with pre- and post-treatment CRP ≥1.0 mg/dl. RESULTS The 1- and 3-year overall survival rates were 92.3 and 82.9 % for group 1, 80.0 and 53.3 % for group 2, and 58.8 and 4.2 % for group 3. The overall survival rate for group 3 was significantly lower than that for group 1 (P < 0.0001), or group 2 (P = 0.003). No significant difference was found between groups 1 and 2 (P = 0.627). A multi-variate analysis showed that albumin level (P = 0.049), the CRP group (P < 0.0001), and the Cancer of the Liver Italian Program (CLIP) score (P < 0.0001) were independently associated with the overall survival. CONCLUSIONS A persistently elevated CRP level after initial treatment is an independent marker of a poor prognosis, and normalization of the CRP level after initial treatment is associated with a better outcome in patients with HCC.

Abstract
Background: Inflammation-based prognostic scores including the Glasgow Prognostic Score (GPS), neutrophil to lymphocyte ratio (NLR), and Prognostic Nutritional Index (PNI) are associated with survival in patients with hepatocellular carcinoma (HCC). The aim of this study was to investigate the prognostic value of these inflammation-based prognostic scores in patients with HCC. Methods: In total, 150 patients with newly diagnosed HCC were prospectively evaluated. Patients were divided according to the GPS, modified GPS, NLR, platelet to lymphocyte ratio (PLR), Prognostic Index (PI), and PNI. The area under the receiver operating characteristics curve (AUC) was calculated to compare the predictive ability of each of the scoring systems. A univariate and multivariate analysis were performed to identify the clinicopathological variables associated with overall survival. Results: The GPS consistently had a higher AUC value at 6 months (0.768), 12 months (0.787), and 24 months (0.758) in comparison with other inflammation-based prognostic scores. A multivariate analysis showed that the GPS was independently associated with overall survival. Conclusion: This study demonstrates that the GPS, an inflammation-based prognostic score, is an independent marker of poor prognosis in patients with HCC and is superior to the other inflammation-based prognostic scores in terms of prognostic ability.

Abstract
AIMS/HYPOTHESIS In type 2 diabetic patients at low risk for cardiovascular disease (CVD), the relationship between the clinical course of nephropathy by stage of chronic kidney disease (CKD) and onset of CVD remains unclear. Clarification of this relationship is important for clinical decision-making for both low- and high-risk diabetic patients. METHODS This 4 year prospective study enrolled 2,954 type 2 diabetic patients with no prevalent CVD, and serum creatinine <176.8 μmol/l. The risk for CVD onset (non-fatal and fatal CVD and stroke, and peripheral arterial disease) was assessed according to CKD stage categorised by urinary albumin-to-creatinine ratio (ACR; mg/mmol) and estimated GFR (eGFR; ml min(-1) 1.73 m(-2)). Association of progression from 'no CKD' stage (ACR <3.5 mg/mmol and eGFR ≥ 90 ml min(-1) 1.73 m(-2)) with risk for CVD onset was also evaluated. RESULTS During follow-up (median 3.8 years), 89 CVD events occurred. Compared with patients with 'no CKD' as reference, those with ACR ≥ 35.0 mg/mmol with co-existing eGFR 60-89 ml min(-1) 1.73 m(-2) or <60 ml min(-1) 1.73 m(-2) showed increased risk for CVD onset, whereas those with eGFR ≥ 90 ml min(-1) 1.73 m(-2) did not. Those with ACR <3.5 mg/mmol and eGFR <60 ml min(-1) 1.73 m(-2) did not show any increased risk. Among patients with 'no CKD' stage at baseline, those who progressed to ACR ≥ 3.5 mg/mmol during follow-up showed an increased risk compared with those who did not, whereas those who progressed to eGFR <90 ml min(-1) 1.73 m(-2) did not have increased risk. CONCLUSIONS/INTERPRETATION The risk for CVD was associated with progression of albuminuria stage rather than eGFR stage in type 2 diabetic patients at relatively low risk for CVD.

Abstract
AIM The aim of this study was to determine the relationship between the development of diabetes mellitus and high-sensitivity C-reactive protein (HsCRP) adjusted for various potential confounders. METHODS This 5-year prospective cohort study was conducted at a Japanese steel factory and involved male workers who had received annual health screenings between 2005 and 2010. The 7392 male participants were aged 19-75 years. The study endpoint, the development of diabetes mellitus, was defined as HbA(1c) greater or equal to 6.5% or the use of antidiabetic medication. The association between variables was investigated using pooled logistic regression adjusted for various covariates such as age, baseline body mass index (BMI) and increase in BMI from baseline, blood biochemistry, job schedule and job-related stress. RESULTS The incidence rate of diabetes development per 1000 person-years was 13.9. Multivariate analysis showed a significant relationship between the development of diabetes and elevated levels of baseline HsCRP and increases in levels from baseline. The Odds ratios for a 2.9-fold (±1 geometric standard deviation) increase in baseline HsCRP and increase in HsCRP level from baseline were 1.18 [95% confidence interval (CI): 1.03-1.34; P=0.018] and 1.21 (95% CI: 1.03-1.41; P=0.018), respectively. CONCLUSION The present study has indicated that HsCRP is an independent predictor for the development of diabetes in men, together with various confounders such as BMI, type of job schedule and job-related stress.

Abstract
OBJECTIVE: Glycaemic control is critical to prevent diabetic complications and mortality. This 6-month, open-label, observational study assessed the efficacy and safety of switching Japanese patients with type 2 diabetes from neutral protamine Hagedorn (NPH) insulin to insulin detemir. METHODS: Patients with type 2 diabetes ( n = 126) receiving basal—bolus insulin therapy with NPH insulin plus rapid-acting insulin analogues were recruited. NPH insulin was replaced with insulin detemir for 6 months. Glycosylated haemoglobin (HbA1c), fasting plasma glucose (FPG), daily glucose levels and hypoglycaemia were monitored. Nocturnal quality of life was assessed by insulin therapy related quality of life at night questionnaire. RESULTS: HbA1c, FPG and body weight were all significantly reduced after treatment with insulin detemir for 6 months, without increasing severe hypoglycaemia. Insulin dose increased significantly over the same time. There were significant improvements in overall nocturnal quality of life, as well as well-being. CONCLUSIONS: Treatment with insulin detemir for 6 months resulted in substantial benefits, including reduced HbA1c, FPG and body weight, and improvements in nocturnal quality of life, without increasing hypoglycaemia.

Abstract
BACKGROUND/AIMS Excess production of nitric oxide (NO) by inducible nitric oxide synthase (iNOS) has been implicated as proinflammatory biomarker in liver injury. The application of active hexose correlated compound (AHCC) as a functional food in complementary and alternative medicine has increased. The possibility that AHCC might inhibit iNOS induction was investigated as a potential liver-protective effect. METHODS Hepatocytes were isolated from rats by collagenase perfusion and cultured. Primary cultured hepatocytes were treated with interleukin-1β in the presence or absence of AHCC-sugar fraction (AHCC-SF). RESULTS AND CONCLUSION AHCC-SF inhibited the production of NO and reduced expressions of iNOS mRNA and its protein. AHCC-SF had no effects on either IκB degradation or nuclear factor-κB (NF-κB) activation. In contrast, AHCC-SF inhibited the upregulation of type I interleukin-1 receptor (IL-1RI) through the inhibition of Akt phosphorylation. Transfection experiments with iNOS promoter-luciferase constructs revealed that AHCC-SF reduced the levels of iNOS mRNA at both promoter transactivation and mRNA stabilization steps. AHCC-SF inhibited the expression of iNOS gene antisense transcript, which is involved in iNOS mRNA stabilization. These findings demonstrate that AHCC-SF suppresses iNOS gene expression through a IκB/NF-κB-independent but Akt/IL-1RI-dependent pathway, resulting in the reduction of NO production. AHCC-SF may have therapeutic potential for various liver injuries.

Abstract
Serum amyloid A low-density lipoprotein (SAA-LDL) is formed by an oxidative interaction and is considered to be a new marker related to oxidative modification of LDL. As the effect of smoking on oxidized LDL is of concern, this study investigated the association between SAA-LDL and smoking status. A total of 578 Japanese obese outpatients (mean ± SD age 50.5 ± 14.3 years) were studied. Smoking status was examined via a self-reported questionnaire. Cardiometabolic variables, including high-sensitivity C-reactive protein (hsCRP), were analysed in addition to SAA-LDL. There was an increasing trend in SAA-LDL levels from non- to ex- to current smokers, and significantly higher SAA-LDL levels were observed in current smokers versus non-smokers (median SAA-LDL level 36 μg/ml versus 28 μg/ml, respectively). This significant difference was reduced after adjusting for multiple confounders, including lipid levels. Smoking may be associated with increased levels of SAA-LDL in an obese Japanese population, but further studies are needed.

Abstract
AIMS To investigate whether a reduced incidence of cardiovascular disease in Type 2 diabetes can be achieved in a newly recruited cohort following the recently advanced concept of multifactorial treatment and followed in primary care settings as compared with earlier cohorts. METHODS A prospective study was performed in primary care settings at multiple clinics nationwide in the Japan Diabetes Clinical Data Management (JDDM) study group. Subjects were 2984 patients with Type 2 diabetes without prevalent cardiovascular disease. The main outcome measure was the first event of non-fatal or fatal coronary heart disease, ischaemic stroke or peripheral artery disease, and the incidence was compared with other representative cohorts. RESULTS There were 90 cardiovascular events over 10,827 person-years of follow-up with a dropout rate of 6%. The incidences (per 1000 person-years, 95% confidence interval) of composite, coronary heart disease, ischaemic stroke and peripheral artery disease in the JDDM study were 8.3 (6.6-10.0), 4.4 (3.2-5.6), 3.1 (2.1-4.2), and 0.7 (0.2-1.2), respectively. Each incidence was lowest in the JDDM study compared with other cohorts (P < 0.01 vs. each cohort). In the JDDM study, significant variables predictive of the occurrence of a cardiovascular event were age, duration of diabetes, HbA(1c), HDL cholesterol and urinary albumin. CONCLUSION The novel finding of low cardiovascular disease occurrence in this study may be conferred by the feasibility at primary care settings for providing patients with Type 2 diabetes with favourable control of blood glucose, blood pressure and lipids, coupled with unique ethnicity/country factors.
