Abstract
BackgroundIn immunoglobulin G4-related kidney disease (IgG4-RKD), persistent renal insufficiency may be observed despite the good initial response to glucocorticoids[1, 2]. However, its long-term prognosis in relation to renal function as well as malignancy and mortality has not been well clarified.ObjectivesTo clarify the long-term renal prognosis, complications of malignancy, mortality, and factors related to those outcomes in IgG4-RKD.MethodsWe retrospectively reviewed the medical records of patients with IgG4-RKD diagnosed by the expert members of the IgG4-RKD working group in the Japanese Society of Nephrology. We investigated clinical, radiological, and histopathological features at baseline and course of renal function, complications of malignancy, and mortality during the long-term observation periods (median 71 months) in 75 patients. Using collected data, we calculated the crude incidence rates (IR) of chronic kidney disease (CKD) status, malignancy, and death. Cox regression analyses were performed to assess CKD-related factors. Additionally, we calculated the standardized incidence ratio (SIR) of malignancy and standardized mortality ratio (SMR) using national Japan statistics.ResultsFifty-nine patients were male, and 16 were female (median age 70 years). At diagnosis, their median eGFR was 45.1 mL/min/1.73m2 (interquartile range [IQR] 28.6-69.9). Seventy-two patients (96%) were treated with prednisolone at a median initial dose of 30 (IQR 30-39) mg/day, leading to a reasonable initial improvement of renal function. The IR of CKD was 30.2/100 person-years, and 66.7% (50/75) of the patients showed CKD at the last visit. Age- and sex-adjusted Cox regression analyses indicated that lower eGFR (per 10 mL/min/1.73m2, hazard ratio [HR] 0.70, 95% confidence interval [CI] 0.61-0.80), pre-existing hypertension (HR 2.39, 95% CI 1.32-4.34), and wider areas with inflammation (>50% vs. <10%, HR 2.55, 95% CI 1.07-6.08) or fibrosis (>50% vs. <5%, HR 2.84, 95% CI 1.18-6.85) in the biopsied renal specimens at treatment initiation had a significant impact on the time to CKD. Eight patients (10.7%) died during follow-up due to malignancy, severe infection, cerebral hemorrhage, or myocardial infarction. The crude mortality rate was 1.76/100 person-years, and a SMR calculated according to national Japan statistics was 0.97 (95% CI 0.42-1.90). On the other hand, 15 patients were diagnosed as having malignancies during follow-up. The IR of malignancy was 3.71/100 person-years, and the SIR of malignancy was 1.80 (95% CI 1.03-2.93).ConclusionThis study suggests that pre-treated renal insufficiency and extensive renal inflammatory and fibrotic lesions are related to CKD under glucocorticoid therapy in IgG4-RKD. Similarly with the whole IgG4-related disease, IgG4-RKD may have an increased incidence of malignancy but a mortality rate equivalent to the age- and sex-matched Japanese population.References[1]Saeki T et al.

Abstract
Background:The 2019 ACR/EULAR classification criteria for IgG4-RD have recently been published1). In the criteria, patients with an inclusion criteria score of >20 without exclusion criteria are classified as having IgG4-RD.Objectives:To validate the 2019 ACR/EULAR classification criteria for IgG4-RD in a Japanese kidney disease cohort.Methods:The study involved Japanese patients diagnosed as having kidney disease between April 2012 and May 2019, for whom sufficient clinical information and data on serum IgG4 values and/or immunohistological staining for IgG4 in renal biopsy samples were known. These patients were classified as having IgG4-RKD or non-IgG4-RKD (mimickers) based on the 2019 ACR/EULAR classification criteria for IgG4-RD, and the results were evaluated by expert opinion.Results:Among 105 included patients, the expert panel diagnosed 55 as having true IgG4-RKD and 50 as mimickers. The final diagnoses among the mimickers were vasculitis (n=11), idiopathic tubulointerstitial nephritis (TIN) (n=5), drug-induced TIN (n=5), Sjögren’s syndrome (n=4) and others. Among the 55 true IgG4-RKD patients, 4 had exclusion criteria, and 50 of the remaining 51 had an inclusion criteria score of ≥20 points (sensitivity 90.9%). On the other hand, 49 of the 50 mimickers were classified as having non-IgG4-RKD (specificity 98.0%) (Table 1).Table 1.General characteristics and prevalence of individual items of true IgG4-RKD and non-IgG4-RKD (mimicker)IgG4-RKD(true IgG4-RKD)(n=55)Non-IgG4-RKD(mimicker)(n=50)PAge at diagnosis,mean ±SD (years)69.9 ± 9.456.7 ± 17.4<0.001Male (%)76.4440.001Elevated serum IgG454/55 (98.2%)18/50 (36.0%)<0.001Serum IgG4 (mg/dl), mean±SD1028 ± 796226 ± 261<0.001Dense IgG4+Plasma cells (>10/hpf) in the kidney biopsy48/51 (94.1%)13/40 (32.5%)<0.001Storiform fibrosis in the kidney biopsy28/51 (54.9%)3/50 (6%)<0.001Hypocomplementemia39/55 (70.1%)7/42 (16.7%)<0.001Renal pelvis thickening/soft tissue5/55 (9%)1/50 (2%)0.20Bilateral renal cortex low-density areas29/55 (52.7%)7/50 (14.0%)<0.001Exclusion criteria present4/55 (7.3%)22/50 (44%)<0.001Total inclusion criteria points >20 without exclusion criteria50/55 (90.9%)1/50 (2%)<0.001Conclusion:The 2019 ACR/EULAR classification criteria for IgG4-RD showed good agreement with expert classification in this Japanese kidney disease cohort.References:[1] Wallace ZS, et al.

Abstract
Abstract
[Background]
Many of the tripartite motif (TRIM) proteins, like Efp/TRIM25 which was identified by our group previously (Nature 417, 871-875, 2002), function as E3 ubiquitin ligases, and are thought to be involved in various physiological and pathological processes such as immunity and oncogenesis. In regard to tripartite motif containing 44 (TRIM44), which is an atypical TRIM family protein lacking RING finger domain, some evidences suggest that it is implicated in the progression of several human malignancies. But its pathophysiological significance in breast cancer remains unknown.
[Methods]
In the present study, immunohistochemical analysis using anti-TRIM44 antibody was performed in clinical breast cancer tissues from 129 patients with the approval of institutional ethical committees (approval number: 845). We then explored the pathophysiological role of TRIM44 in breast cancer by modulating TRIM44 expression in MCF-7 and MDA-MB-231 breast cancer cells.
[Results]
TRIM44 strong immunoreactivity was significantly associated with nuclear grade, distant disease-free survival and overall survival of the breast cancer patients. With multivariate analysis it was shown that the TRIM44 status was an independent prognostic factor for distant disease-free survival and overall survival. The proliferation of MCF-7 and MDA-MB-231 cells was significantly decreased by siRNA-mediated TRIM44 knockdown. TRIM44 knockdown also suppressed migration of MDA-MB-231 cells. Microarray analysis and qRT-PCR revealed that TRIM44 knockdown upregulated CDK19 (Cyclin Dependent Kinase 19), which is reported to be a tumor suppressor gene, whereas downregulated MMP1 (Matrix Metallopeptidase 1) in MDA-MB-231 cells. Notably, TRIM44 knockdown impaired nuclear factor-kappa B (NF-κB)-mediated transcriptional activity stimulated by tumor necrosis factor α (TNFα). Moreover, TRIM44 knockdown substantially attenuated the TNFα-dependent phosphorylation of p65 subunit of NF-κB and IκBα in both MCF-7 and MDA-MB-231 cells.
[Discussion]
Our clinical study showed that prognosis of breast cancer patients is correlated with the immunoreactivity detected by anti-TRIM44 antibody. This result suggested that expression of TRIM44 protein could be used as a potential biomarker of breast cancer. We demonstrated that NF-κB signaling pathway is modulated by TRIM44. Since NF-κB augmentation is shown to be related to aggressive character of breast cancer, stimulation of NF-κB signaling with TRIM44 might be underlying mechanism of poor prognosis. Our in vitro study showed TRIM44 knockdown caused attenuated proliferation and migration of breast cancer cells, raising the possibility of TRIM44 as a potential therapeutic target for breast cancer. These findings provide new clues to develop alternative effective strategies for breast cancer management.

Abstract
Combination therapy with everolimus and an aromatase inhibitor such as exemestane is an effective treatment option for advanced or recurrent breast cancer. However, the therapy is often limited because of the occurrence of severe adverse events (AEs), including oral mucositis, interstitial lung disease, diarrhea, and rash. Therefore, early management of AEs is extremely important to obtain maximum treatment outcome. We investigated here the effects of comprehensive pharmaceutical care for prevention of severe AEs on patient's quality-of-life (QOL) and continuation of therapy. QOL was assessed every month based on the five-level version of EuroQol-5-Dimension (EQ-5D-5L). AEs were graded according to the Common Terminology Criteria for Adverse Events (ver 4.0). Implementation of comprehensive pharmaceutical care remarkably reduced the incidence of severe oral mucositis as compared with those without such interventions. EQ-5D-5L health states were almost constant during 6 months after intervention, ranging from 0.850 to 0.889. Median time to treatment failure (TTF) was significantly longer after intervention than before [224.0 days, 95% confidence interval (CI): 117-331 days versus 34 days, 21-47 days, hazard ratio (HR): 0.027, 95% CI: 0.005 - 0.154, p<0.001]. These findings suggest that our comprehensive pharmaceutical care is highly effective for enhancing treatment outcome by maintaining patient's QOL.

Abstract
Abstract
Background: In patients with HER2-positive metastatic breast cancer (MBC) who progressed on trastuzumab (H)-based therapy, both continuing H beyond progression and switching to lapatinib (L) in combination with chemotherapy are valid options. However, it is unclear which strategy is more effective and how we can select a proper strategy in each patient.
Methods: We conducted an open label, multicenter, randomized phase II trial to comparatively evaluate efficacy and safety of H + capecitabine (X) (HX) or L + X (LX) in women with HER2-positive MBC who were previously treated with taxanes and progressed on H-containing regimens. Patients treated with more than two chemotherapy regimens for MBC were excluded. Those treated with pertuzumab and/or T-DM1 were allowed to enroll in this study. Patients with brain metastases were also included if they are asymptomatic. Patients received H (4mg/kg loading then 2mg/kg weekly or 8mg/kg loading then 6mg/kg every 3 weeks) and X (2500 mg/m2/day on days 1-14 every 3weeks) in HX arm and L (1250 mg/day) and X (2000 mg/m2/day on days 1-14 every 3weeks) in LX arm until progression or intolerable toxicity. The primary endpoint was progression-free survival (PFS) and secondary endpoints included overall survival (OS), objective response rate (ORR), proportion of subjects progressing with brain metastases as site of first progression, and safety.We also assessed biomarkers in tumor tissues and circulating cell-free DNA.
Results: Between May 2011 and December 2014, 86 patients (43 in HX arm and 43 in LX arm) were enrolled in this study. Median age was 58 years (range 34-81), ECOG performance status was 0 (63%), 1 (35%), or 2 (2%), 63% had hormone receptor-positive disease, 15% had brain metastases, 56% had relapsed after primary surgery, and 23% had received adjuvant or neo-adjuvant trastuzumab. Median follow-up time was 44.6 months. Median PFS was 6.1 months in HX arm and 7.1 months in LX arm (hazard ratio 0.81 90% CI 0.55-1.21; p=0.39), median OS was 31.0 months in HX arm and not reached in LX arm (hazard ratio 0.58 95% CI 0.26-1.31; p=0.18), ORR was 40% in HX arm and 41% in LX arm (p=1.00), disease control rate was 73% in HX arm and 92% in LX arm (p=0.038), and proportion of subjects progressing with brain metastases as site of first progression was 5% in HX arm and 5% in LX arm. Grade 3-4 toxicities included hand-foot syndrome (21% in HX arm and 21% in LX arm) and diarrhea (9% in HX arm and 16% in LX arm). In subgroup analyses, PFS benefit in LX arm compared to HX arm was significantly larger among patients who had received previous systemic treatment for metastatic disease for less than 1 year (interaction p=0.007). Subgroup analyses by biomarkers will be presented at the meeting.
Conclusions: In women with HER2-positive MBC previously treated with trastuzumab and taxanes, lapatinib + capecitabine tended to yield better PFS and OS than trastuzumab beyond progression + capecitabine, although they were not statistically significant.Background: In patients with HER2-positive metastatic breast cancer (MBC) who progressed on trastuzumab (H)-based therapy, both continuing H beyond progression and switching to lapatinib (L) in combination with chemotherapy are valid options.

Abstract
Increasing atmospheric carbon dioxide (CO2) is the principal driver of anthropogenic climate change. Asia is an important region for the global carbon budget, with 4 of the world's 10 largest national emitters of CO2. Using an ensemble of seven atmospheric inverse systems, we estimated land biosphere fluxes (natural, land-use change and fires) based on atmospheric observations of CO2 concentration. The Asian land biosphere was a net sink of −0.46 (−0.70–0.24) PgC per year (median and range) for 1996–2012 and was mostly located in East Asia, while in South and Southeast Asia the land biosphere was close to carbon neutral. In East Asia, the annual CO2 sink increased between 1996–2001 and 2008–2012 by 0.56 (0.30–0.81) PgC, accounting for ∼35% of the increase in the global land biosphere sink. Uncertainty in the fossil fuel emissions contributes significantly (32%) to the uncertainty in land biosphere sink change. Land biosphere uptake of carbon is important in mitigating the anthropogenic increase in atmospheric CO2 and its climate forcing. Here, the authors show that land biosphere uptake of carbon in Asia has increased substantially since the mid 1990s, likely owing to reforestation and regional climate change.

Abstract
Abstract
Background: Diffuse optical spectroscopic imaging (DOSI) can be exploited as a marker of tumor blood volume quantified by tissue hemoglobin (tHb) concentration. In DOSI, frequent measurement is possible for breast cancer patients because of its non-invasiveness. The tHb concentration determined by DOSI is expected to be a new biomarker for prediction of breast cancer response to neoadjuvant chemotherapy (NAC).
Purpose: Our objective is to determine whether early change of tumor tHb concentration predicts pathological complete response (pCR) to NAC in patients with operable breast cancer.
Methods: In a prospective study, one hundred patients with primary breast cancer were enrolled for primary objective analysis. The regimens of NAC were according to the standard of care. Patients underwent sequential scans using DOSI at baseline, after 1st course and 2nd course of chemotherapy. The mean value of tHb (tHbmean) concentration of the targeted lesion was measured and the percentage change in tHbmean (ΔtHbmean) concentration was calculated. Receiver operating curve analysis demonstrated diagnostic performance of DOSI for predicting a pCR.
Results: In interim analysis, it was regarded as a good outcome that area under the curve (AUC) for ΔtHbmean after 1nd course was 0.797 (SE 0.104, 95%CI 0.633-0.911), and after 2st course was 0.867 (SE 0.06, 95%CI 0.715-0.956).
Conclusion: DOSI could predict accurately a pCR to neoadjuvant chemotherapy in patients with primary breast cancer.

Abstract
Most primary breast cancers express estrogen receptor α and can be treated via endocrine therapy using anti-estrogens such as tamoxifen; however, acquired endocrine resistance is a critical issue. To identify tamoxifen response-related microRNAs (miRNAs) in breast cancer, MCF-7 cells infected with a lentiviral miRNA library were treated with 4-hydroxytamoxifen (OHT) or vehicle for 4 weeks, and the amounts of individual miRNA precursors that had integrated into the genome were evaluated by microarray. Compared to the vehicle-treated cells, 5 'dropout' miRNAs, which were downregulated in OHT-treated cells, and 6 'retained' miRNAs, which were upregulated in OHT-treated cells, were identified. Of the dropout miRNAs, we found that miR-574-3p expression was downregulated in clinical breast cancer tissues as compared with their paired adjacent tissues. In addition, anti-miR-574-3p reversed tamoxifen-mediated suppression of MCF-7 cell growth. Clathrin heavy chain (CLTC) was identified as a miR-574-3p target gene by in silico algorithms and luciferase reporter assay using the 3' untranslated region of CLTC mRNA. Interestingly, loss and gain of miR-574-3p function in MCF-7 cells causes CLTC to be upregulated and downregulated, respectively. These results suggest that functional screening mediated by miRNA libraries can provide new insights into the genes essential for tamoxifen response in breast cancer.

Abstract
Abstract Although several recent reports have discussed the similarities between human parvovirus B19 (HPV-B19) infection and systemic lupus erythematosus (SLE), the relationship between these conditions has not been established owing to the small number of patients investigated. In 1998-1999, an outbreak of Erythema infectiosum occurred close to our hospital, enabling us to investigate the clinical, hematological, and serological findings, including serum complement and antinuclear antibodies (ANA), in 22 patients with acute HPV-B19 infection. The principal symptoms included rash (86.3%), edema (59%), arthralgia (45.4%) and fever (31.8%). Lymphadenopathy was seen in three of the 22 cases. The laboratory findings showed high incidences of leukopenia (50%), hypocomplementemia (95%), and ANA (64.7%). At the time of disease onset, patients with acute HPV-B19 infection presented with features which were similar to those of SLE. The possibility of HPV-B19 infection should therefore be considered in patients presenting with SLE-like features.

Abstract
Abstract
Background: S-1 is an oral, fixed dose combination product comprised of tegafur, a fluoropyrimidine prodrug of 5-fluorouracil (5-FU), and modulators of 5-FU metabolism, 5-chloro-2.4-dihydrooxypyridine and oteracil potassium. S-1 is designed to provide oral delivery of 5-FU, a pyrimidine analog antimetabolite antineoplastic agent, while reducing the rate of degradation of 5-FU and its conversion in the gastrointestinal tract to its toxic phosphorylated metabolite. S-1 is active in breast cancer and a variety of solid tumors. nab™-Paclitaxel (nab-P) is a treatment option in metastatic breast cancer (MBC) (approved 260 mg/m2 q3w dosing schedule), and high activity of nab-P with single-agent weekly administration at 100 mg/m2 has been investigated in MBC as well as other disease states. Since these two agents differed in their mechanisms of action and toxicity profiles, we sought to test their combined activity in a phase I study of nab-P/S-1 for HER2-negative MBC. The primary objectives of this study was to determine the maximum tolerated dose (MTD) and recommended dose (RD) of nab-P/S-1 in patients with HER-2 negative MBC. The secondary objective of this study was to evaluate pharmacokinetic (PK) parameters of both agents.
Methods: Patients received treatment on 3 week cycles. S-1 was administered orally at a twice-daily dose of 65 mg/m2 (dose level 1 and 2b) or 80 mg/m2 (dose level 2a and 3) for 14 days and nab-P was administered as a 30-minute IV infusion at a dose of 100 mg/m2 on days 1 and 8 (dose level 1 and 2b) or 100 mg/m2 on days 1, 8 and 15 (dose level 2a and 3).
Results: Fifteen patients were enrolled in this study; nab-P/S-1 was given as first-line chemotherapy for MBC in 9 patients, and as second-line therapy subsequent to an anthracycline-containing therapy in 6 patients. At dose level 3, one patient experienced a DLT. The observed DLT was delay of initiation of next cycle, G4 neutropenia had not recovered to G1/G0 in a period defined on the protocol. No cases of febrile neutropenia were observed. Judged from the status of dose reduction and the extension of drug holidays (cycle start delay), and the occurrence of non-severe adverse events after 2 cycles, the dose level was not increased above level 3. Seven patients were able to be treated 10 cycles or more. Additionally, three patients were able to be treated 20 cycles or more. Among of the 12 patients who had a measurable lesion which was evaluable by RECISTv1.1, the overall response rate was 50%, with 1 CR, 5 PR, 4 SD, and 1 PD. Pharmacokinetics of Paclitaxel and 5-FU in the combination therapy were comparable to those after single-agent administration of nab-P and S-1, respectively.
Conclusion: Based on the results of this study, the RD was determined to be dose level 3 (S-1 80 mg/m2 twice daily plus nab-P 100 mg/m2 on days 1, 8, and 15). Since this combination therapy was generally well tolerated even with prolonged treatment, it is suggested that this combination therapy may be a promising treatment regimen in HER-2 negative MBC and merits further evaluation.

Abstract
Abstract
We have reported that a transient increase of oxyhemoglobin level measured 24 hours after the start of neoadjuvant chemotherapy using noninvasive Diffuse Optical Spectroscopic Imaging (DOSI) may be useful in discriminating nonresponding from reponding breast cancer patients (PNAS. 2011 Aug 30;108(35):14626–31). To elucidate the underlying biological mechanism, we compared optical measured hemoglobin levels to tissue biomarkers in a rat tumor model.
Method: An orthotopic mammary tumor model using Fischer 344 rats and MAT3B cells was used for this experiment. 16 mg of cyclophosphamide was administered (i.p.) in 15 rats after tumors had grown to a significant size. A wide-field functional imaging device that utilizes structured near-infrared light was used to measure superficial absolute concentrations of oxyhemoglobin (ctO2Hb) and deoxyhemoglobin (ctHHb) of the tumors. Rats were imaged and sacrificed (two per timepoint) at each of the following timepoints: baseline, 2, 6, 12, 24, 48, 96 hours, and day 8 following the injection. Resected tumors were sectioned after paraffin-embedding and representative slides were used for immunohistochemistry. Cellular markers of proliferation (measured by Ki67), apoptosis (Caspase3), NK cells (ANK61), and macrophages (MAC387) were counted in each slide using Image J software.
Result: Average tumors baseline values of ctO2Hb and ctHHb were 81.4 µM (±9.2 SD) and 22.4 µM (±4.1 SD) respectively. In most rats, both levels gradually increased from baseline to 24 hours after the injection and reached a maximum at 48 hours and then declined until Day 8. At 24 hours, ctO2Hb was significantly higher than baseline [96.8 µM (±8.8 SD) vs. 81.4µM (±9.2 SD), p = 0.003 using Student's t-test]. This trend was mimicked in the tissue markers of cellular proliferation and apoptosis, which peaked at 24 through 48 hours and then dropped. The average NK cell count was also found to rise consistently through the course of monitoring and reached the highest at day 8, while macrophage counts reached a peak at 48 hours and then declined. The differences between baseline and 24 hours for these were statistically significant: Ki67 [294 (±107 SD) vs. 115 (±68 SD), p = 0.0002], Caspase3 [2916 (±1383 SD) vs. 136 (±150 SD), p < 0.0001], NK cells [635 (±329 SD) vs. 159 (±110 SD), p = 0.0001], and macrophage markers [281 (±260 SD) vs. 39 (±31 SD), p = 0.01].
Conclusion: We observed an increase in oxyhemoglobin early after chemotherapy, closely linked to changes in cellular proliferation, apoptosis, NK cells and macrophage accumulation. Early optical changes may be linked to chemotherapy-induced tumor metabolic and acute inflammatory responses.

Abstract
Ribonucleotide reductase (RNR) consists of two non-identical subunits, R1 and R2 and is one of the key enzymes involved in DNA biosynthesis. RNR activity is considerably higher in malignant tumors than in normal tissues in the rat suggesting that RNR may play an important role in the pathogenesis of human tumors. In order to obtain immunological reagents to study the localization and level of expression of RNR in various human tissues, a synthetic peptide containing sequences corresponding to the COOH-terminal region of the human R2 subunit was used to generate rat monoclonal antibodies. The generated rat monoclonal antibodies (IgG) inhibited RNR enzymatic activity purified from murine P388 leukemia cells. These antibodies were used to immunohistochemically examine the distribution of RNR in a small panel of 8 malignant and 4 benign human breast tumors. Positive immunostaining for RNR was observed in the cytoplasm of human breast carcinoma cells in which a specific 44 kDa specific band of R2 subunit was also detected by Western blot analysis. The immunostaining was blocked by preabsorption of the antibody with an excess amount of the synthetic peptide immunogen. In 8 of 8 breast carcinomas, positive immunostaining for the R2 subunit was observed whereas noninvolved, adjacent breast tissue showed no staining with this antibody. In addition, few of the benign breast lesions exhibited staining with this antibody. These data indicate that these antibodies can immunohistochemically detect RNR in frozen or formalin-fixed, paraffin- embedded tissues and that there is a differential expression of RNR between breast tumors and non-involved breast tissue. Immunohistochemical detection of RNR using these antibodies may therefore be useful for the diagnosis of human breast tumors.

Abstract
The expression and localization of cripto-1 (CR-1), amphiregulin (AR) and transforming growth factor alpha (TGFalpha) were assessed by immunocytochemistry in 37 primary human gastric tumors, 30 noninvolved gastric mucosa samples that were adjacent to carcinoma but exhibited intestinal metaplasia and 37 adjacent, noninvolved gastric mucosa samples. Seventeen (46%), nineteen (51%) and twenty-one (57%) carcinomas showed staining for CR-1, AR and TGFalpha, respectively; whereas sixteen (53%), eight (26%) and five (17%) intestinal metaplasias were reactive with the anti-CR-1, anti-AR and anti-TGFalpha antibodies, respectively. In contrast, none of the normal, noninvolved gastric mucosa samples reacted with the TGFalpha antibody and only 1 (3%) of these samples showed weak staining with the anti-CR-1 antibody. However, 8 (21%) of the normal gastric mucosa samples showed moderate levels of staining with the AR antibody. Within the carcinomas, there was a slight trend for association between TGFalpha and CR-1 expression (p<0.05), but no correlation was found between epidermal growth factor receptor and CR-1 expression. Staining for p53 was observed in 26 (70%) of the carcinomas, 3 (10%) intestinal metaplasias and none of the gastric mucosa samples. This data demonstrate that CR-1, like TGFalpha, may be a tumor marker for a subset of gastric carcinomas in addition to being an important factor in the early stages of gastric cancer development.

Abstract
A search is made for charged Higgs bosons predicted by Two-Higgs-Doublet extensions of the Standard Model (2HDM) using electron-positron collision data collected by the OPAL experiment at [Formula: see text], corresponding to an integrated luminosity of approximately 600 pb-1. Charged Higgs bosons are assumed to be pair-produced and to decay into [Formula: see text], τντ or AW±. No signal is observed. Model-independent limits on the charged Higgs-boson production cross section are derived by combining these results with previous searches at lower energies. Under the assumption [Formula: see text], motivated by general 2HDM type II models, excluded areas on the [Formula: see text] plane are presented and charged Higgs bosons are excluded up to a mass of 76.3 GeV at 95 % confidence level, independent of the branching ratio BR(H±→τντ ). A scan of the 2HDM type I model parameter space is performed and limits on the Higgs-boson masses [Formula: see text] and mA are presented for different choices of tanβ.

Abstract
Abstract
Estrogen signaling pathways are involved in the growth and development of breast tumors through the activation of estrogen receptor a (ERα). ERα is expressed in most breast cancers and involves in estrogen-dependent proliferation by acting as transcription factors activating the expression of target genes. Various coregulators and transcription factors are associated with ERα-mediated transcriptional control of target genes. Therefore, a comprehensive understanding of estrogen signaling pathways in breast cancer is required for both treatment and diagnosis of the disease. Forkhead box P1 (FOXP1) is a member of the forkhead box transcription factor family and has been reported to be associated with various types of tumors. Here, we investigated the expression pattern of FOXP1 by immunohistochemistry in a series of 133 invasive breast cancers and compared it with clinicopathological factors. The expression of FOXP1 was detected in nuclei in 89 cases (67%) and correlated positively with tumor grade and hormone receptor status, including ERα and progesterone receptor (PgR), and negatively with pathological tumor size (pT). And in ERα-positive MCF-7 breast cancer cells, we demonstrated that FOXP1 mRNA was upregulated by estrogen and that ERα recruitment to ER binding sites within the FOXP1 gene region identified by ChIP-chip analysis was increased. We also demonstrated that proliferation of MCF-7 cells was increased by exogenously transfected FOXP1 and decreased by FOXP1-specific siRNA. Moreover, in MCF-7 cells, FOXP1 enhanced estrogen response element (ERE)-driven transcription. Finally, FOXP1 immunoreactivity was significantly more elevated in relapse-free breast cancer patients treated with tamoxifen than in relapse patients treated with it. Taken together, these results suggest that FOXP1 plays an important role in proliferation of breast cancer cells by modulating estrogen signaling and that FOXP1 immunoreactivity might be associated with the estrogen dependency of breast cancer clinically, which may predict favorable prognosis in the patients treated with tamoxifen.

Abstract
Abstract
Background The steroidal irreversible aromatase inhibitor (AI) exemestane (E), the non-steroidal reversible AI anastrozole (A) and tamoxifen (T) are approved for the first-line treatment of the postmenopausal women with hormone receptor (HR) positive advanced breast cancer (ABC) in Japan. Although there are some studies which compare the efficacy and safety of AIs and T in the first-line disease setting, the number of studies that compare efficacy and safety of AIs is limited. We conducted this multicenter, randomized, double-blinded non-inferiority study, to evaluate the time to progression (TTP) in HR positive ABC randomized to therapy with E or A.
Methods Patients (pts) who were ≥20 years [yrs], postmenopausal, ECOG PS ≤1 and had HR positive ABC that recurred after the adjuvant therapy or metastatic disease settings were eligible and randomized (1:1) to 25 mg/day of E or to 1 mg/day of A. Data were evaluated for non-inferiority of E compared to A defined as the upper limit of a two-sided 95% confidence interval (CI) of the hazard ratio (HR) of TTP being less than or equal to 1.25. The primary endpoint was TTP assessed by the independent radiological images review committee (RIRC). Secondary endpoints included TTP by investigator, time to treatment failure, overall survival (OS), objective response rate (ORR), clinical benefit rate, and safety.
Results A total of 298 pts from 58 sites were randomized to E (n=149; mean age: 63.4 yrs) or A (n=149; mean age: 64.0 yrs). The mean BMI for the E and A arms were 23.0 kg/m2 and 23.6 kg/m2, respectively. Six pts (2 pts in E arm, 4 pts in A arm) were excluded from the full analysis set due to lack of evaluation for anti-tumor response after study medication started.
Median TTP (as per RIRC) was 13.8 months (M) vs. 11.1 M for E vs. A, respectively (HR 1.007; 95% CI: 0.771−1.317). Median TTP (Investigator) was 13.8 M vs. 13.7 M for E vs. A, respectively (HR 1.059; 95% CI: 0.816−1.374). The median OS for A treated pts was 60.1 M, OS for E was not reached (as of data cut-off: December 8, 2010). ORR for E was 43.9% (95% CI: 35.3−52.8) and 39.1% (95% CI: 30.6−18.1) for A. Other analyses, including sub-population analyses are ongoing.
The incidence of treatment related adverse events (AEs) in E arm was 71.1% (n=106) and in A arm 59.7% (n=89); the AEs were mostly grade 1 and 2 in 61.7% (n=92) and 53.7% (n=80) of pts respectively. They were expected and manageable. Treatment related SAEs were similar in both groups: 6 (4.0%) in E arm and 5 (3.4%) in A arm. The most common AEs for E were hot flushes (22.1%), arthralgias (16.8%), musculoskeletal stiffness (11.4%) and γ-GTP increased (10.1%); in A arm, hot flushes (14.8%) and arthralgia (16.8%) were observed in >10% pts.
Conclusions Although median TTP (RIRC) of E is slightly improved compared with that of A, the result of TTP did not meet the non-inferiority criteria. There were no significant differences found between E and A in ORR. Although AEs in E were numerically higher, the observed AE profiles were similar to those previously reported for E and A. This study shows that E is comparable to A in efficacy and safety.

Abstract
Abstract
Background: Local estrogen synthesis may play an important role of progression of breast cancer with hormone receptors. Local progression of breast cancer may depend on high concentration of estrogens and estrogen receptor status. To clarify correlation between expression levels of enzymes in breast cancer and clinicopathological parameters, we analyzed expression of steroid sulfatase(STS), estrogen sulfatase(EST), 17b-hydroxyl steroid dehydrogenase type I & II(17b-HSDI & II) and aromatase. In addition, mRNA expression of estrogens receptor alpha(ERa), estrogen receptor beta(ERb), cycline D1 and erbB2 were measured. Material and Methods: The mRNA expression levels of genes in 196 breast cancer tissues removed from surgery were assayed by RT-PCR. Results: The level of STS were significantly higher in patients with clinical stage. STS expressed none in stage 0 or I, 0.011 in stage II, and 0.013 amol/1 amol b-actin in stage 3 or 4. In addition, EST expressed 58.5 amol/1 amol b-actin in stage 2 and 36.8 in stage 3 or 4, otherwise, the expression level of EST in stage 0 or 1 revealed 15.3 amol/1 amol b-actin. There were no correlation between clinical stage and aromatase expression. Expression levels of ERa and cyclineD1 significantly correlated with protein levels of ER, and there were significant correlation between erbB2 expression and prognosis of patients. Conclusion: Up-regulation of STS play an important role in tumor progression of breast cancer.

Abstract
Abstract
Estrogen activates the estrogen receptor (ER) by recruiting various coregulators and cofactors, resulting in transcriptional regulation of target genes. Recently, we have shown that the FOXP1 forkhead transcription factor is a novel androgen-regulated coregulator for the androgen receptor (Biochem Biophys Res Commun, 374, 388-93, 2008). However, its role in breast cancer is still unknown.Here, we investigated the expression pattern of FOXP1 by immunohistochemistry in a series of 110 invasive breast cancers and compared it with clinicopathological factors. The expression of FOXP1 was detected in nuclei in 76 cases (69.1%) and correlated with expressions of ERα (P=0.001) and progesterone receptor (PgR) (P=0.003), while there was no association with age, lymph node status, size, or grade. Expression levels of FOXP1 mRNA are investigated by qRT-PCR using samples selectively obtained from breast cancer specimens with laser microdissection system (Zeiss Axiovert + P.A.L.M laser microdisection system). ERα, ERβ, and PgR mRNA levels were also measured.Then, we examined expression and function of FOXP1 in human breast cancer MCF-7 cells that possess functional ERα. The expression level of FOXP1 mRNA was up-regulated by estrogen treatment. In addition, estrogen-responsive element-driven luciferase reporter analysis showed that exogenously transfected FOXP1 increased estrogen-dependent transcriptional activity. We also observed that FOXP1 overexpression and knockdown could modulate the growth of MCF-7 cells.Taken together, these findings suggest that FOXP1 plays an important role as a potential ER coregulator in human breast cancer.
