Abstract
OBJECTIVE Schizophrenia (SZ) is characterized by neurobiological and associated cognitive and functional deficits, including pronounced cortical thinning, that lead to acute and long-term functional impairment. Research with older adults supports the role of non-pharmacological interventions, such as exercise (E) and cognitive training (CT), for cognitive impairments. This literature influenced the development of combined CT&E treatments for individuals with SZ. However, the impact of longer combined treatment duration (6 months) on neuroanatomy has yet to be explored in patients in the early course of the illness. The impact of adding exercise to cognitive training for key brain regions associated with higher-order cognition was examined here using magnetic resonance imaging (MRI) in first-episode psychosis (FEP) patients. METHODS UCLA Aftercare Research Program patients with a recent first episode of schizophrenia were randomly assigned to either combined cognitive and exercise training (CT&E) (N = 20) or cognitive training alone (CT) (N = 17) intervention. Cortical thickness was measured longitudinally and analyzed for two regions of interest using FreeSurfer. RESULTS Compared to patients in the CT group, those in the CT&E group demonstrated an increase in cortical thickness within the left anterior cingulate cortex over the six-month treatment period (ACC: F(1, 35) = 4.666, P < .04). Directional tendencies were similar in the left dorsolateral prefrontal cortex (DLPFC: F(1,35) = 4.132, P < .05). CONCLUSIONS These findings suggest that exercise and cognitive training may synergistically increase fronto-cingulate cortical thickness to mitigate progressive neural atrophy in the early course of SZ. This combined intervention appears to be a valuable adjunct to standard pharmacologic treatment in FEP patients.

Abstract
Abstract
Progression of chronic myeloid leukemia, marked by the oncogenic Bcr-Abl mutation, is tightly associated with an alteration of the p53 pathway. It is known that butein extracted from various plants represses cancer growth. Although the anticancer effects of butein are widely accepted, the mechanisms by which butein induces apoptosis of chronic myeloid leukemia cells remains to be elucidated. The present study demonstrated that butein-induced apoptosis was mediated by p53. KBM5 chronic myeloid leukemia (CML) cells expressing wild-type p53 were more sensitive to butein compared with p53-null K562 CML cells in terms of apoptotic cell death. In addition, butein arrested KBM5 cells at S-phase and altered the expression levels of certain cyclins and the p53-downstream targets, MDM2 and p21. In addition, while butein reduced the protein expression of MDM2 in the KBM5 and K562 cells, it resulted in proteasome-independent MDM2 degradation in p53-expressing KBM5 cells, however, not in p53-null K562 cells. Therefore, the present study suggested that p53 causes the butein-mediated apoptosis of leukemic cells.

Abstract
Cancer remains a leading cause of mortality worldwide, therefore food products are being investigated for potential prevention or treatment strategies. The ingredient, barley grass extract (Hordeum vulgare L.; Bex) is used to prevent or ameliorate various types of disease. In cancer, Bex has been revealed to inhibit tumor growth. However, its effect on cancer cells is yet to be clearly defined. In the present study, the effect of Bex on cancer cell growth was investigated. Bex inhibited the viabilities of breast and prostate cancer cells according to the results of MTT assays. Accordingly, Bex caused apoptosis, which was confirmed by Annexin V staining and western blot analysis for poly (ADP-ribose) polymerase and caspases. Furthermore, Bex increased the intracellular levels of reactive oxygen species (ROS), and N-acetyl-L-cystein blocked Bex-induced apoptosis. Therefore, the study demonstrated that Bex causes apoptosis of breast and prostate cancer cells by increasing intracellular ROS levels.

Abstract
Abstract
Defining the full complement of substrates for each ubiquitin ligase remains an important challenge. Improvements in mass spectrometry instrumentation and computation and in protein biochemistry methods have resulted in several new methods for ubiquitin ligase substrate identification. Here we used the parallel adapter capture (PAC) proteomics approach to study βTrCP2, a substrate adaptor for the SKP1-CUL1-F-box (SCF) E3 ubiquitin ligase complex. The processivity of the ubiquitylation reaction necessitates transient physical interactions between βTrCP2 and its substrates, thus making biochemical purification of FBXW11-bound substrates difficult. Using the PAC-based approach, we inhibited the proteasome to “trap” ubiquitylated substrates on the SCF (βTrCP2) E3 complex. Comparative mass spectrometry analysis of immunopurified βTrCP2 protein complexes before and after proteasome inhibition revealed 21 known and 23 putatively novel substrates. Interestingly, many novel substrates for βTrCP2, including TBC1D4, HCFC1, DENND4C, FNIP1, and FLCN are related to cell metabolism. TBC1D4 encodes a GTPase activating protein for the small GTPase Rab that controls insulin-dependent trafficking of the GLUT4 glucose transporter in adipocytes. DENND4C acts as a guanine nucleotide exchange factor for Rab10 and its activity is required for insulin-stimulated GLUT4 translocation to plasma membrane in adipocytes. HCFC1 is a member of the host cell factor family, affecting gluconeogenesis by modulating PGC-1α stability. These suggest βTrCP2 might play important roles in glucose homeostasis by regulating stability of several different target proteins. Here, in focused study, we found that βTrCP1/2 bound, polyubiquitylated, and destabilized FNIP1, FLCN interacting protein 1. We further demonstrated that FNIP1 degradation was promoted by AMPK activation after glucose depletion and expression of a degradation-resistant FNIP1 mutant results in sustained activation of mTORC1 signaling. Hence, our findings reveal that βTrCP1/2 is involved in nutrient sensing through the AMPK-FLCN-FNIP1 and mTORC1 signaling pathways.

Abstract
Abstract
Pancreatic cancer has a poor prognosis and very low survival rate over the world. Because pancreatic cancer probably is diagnosed at a late stage, aggressive local invasion, and poor response to chemotherapy. Gemcitabine was the standard treatment for advanced and metastatic pancreatic cancer patients, but it is associated with multiple adverse effects-fever, fatigue, nausea, and drug resistance. Whether cucurbitacin D has any efficacy against human pancreatic cancer was examined in cell culture system. In vitro, cell viability was measured by MTT assay to recognize of cell cytotoxicity. Consequently, cytotoxicity was observed at a low concentration of cucurbitacin D. Wound healing assay and clonogenic assay indicated that cucurubitacin D inhibited the growth of cell growth through cyclins and CDKs regulation, and decreased colony-forming ability. Also, this compound down-regulated expression level of anti-apoptotic protein, Bcl-2, up-regulated of pro-apoptotic molecule Bax, and activated caspase-8, caspase-3 cascade extrinsic pathway. Additionally, PARP, caspase-3 substrate, protein was cleaved by cucurbitacin D treatment. Overall, our study suggest that cucurbitacin D could be a clinical medicine for the treatment of pancreatic cancers.

Abstract
AIM To investigate the effect of simvastatin on lipopolysaccharide (LPS)-stimulated inflammatory cytokines, cell adhesion molecules and nuclear factor-κB (NF-κB) transcription factors in human dental pulp cells (HDPCs). METHODOLOGY The effect of LPS and simvastatin on human dental pulp cell (HDPCs) viability was measured using a 3-[4, 5-dimethylthiazol-2-yl]-2, 5 diphenyltetrazolium bromide (MTT) assay. The expression of inflammatory cytokines and cell adhesion molecules was evaluated by reverse-transcription polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA) and Western blot analysis. NF-κB transcription factors were evaluated by Western blot analysis. Statistical analysis was performed with analysis of variance (anova). RESULTS The viability of cells exposed to different concentrations of E. coli LPS, P. gingivalis LPS and simvastatin was not significantly different compared with that of control cells (P > 0.05). LPS significantly increased interleukin (IL)-1β (P < 0.05) and IL-6 mRNA expression (P < 0.05) and vascular cell adhesion molecule-1 (VCAM-1) (P < 0.05) and intercellular adhesion molecule-1 (ICAM-1) protein expression (P < 0.05) in HDPCs. Treatment with simvastatin significantly attenuated LPS-stimulated production of IL-1β, IL-6, VCAM-1 and ICAM-1 (P < 0.05). Treatment with simvastatin decreased LPS-induced expression of p65 and phosphorylation of IκB and also significantly decreased the phosphorylation of p65 and IκB in the cytoplasm and the level of p65 in the nucleus (P < 0.05). CONCLUSIONS Simvastatin has a suppressing effect on LPS-induced inflammatory cytokine, cell adhesion molecules and NF-κB transcription factors in HDPCs. Therefore, simvastatin might be a useful candidate as a pulp-capping agent in vital pulp therapy.

Abstract
Although ABT-737, a small-molecule Bcl-2/Bcl-xL inhibitor, has recently emerged as a novel cancer therapeutic agent, ABT-737-induced apoptosis is often blocked in several types of cancer cells with elevated expression of Mcl-1. Cafestol, one of the major compounds in coffee beans, has been reported to have anti-carcinogenic activity and tumor cell growth-inhibitory activity, and we examined whether cafestol could overcome resistance against ABT-737 in Mcl-1-overexpressed human renal carcinoma Caki cells. ABT-737 alone had no effect on apoptosis, but cafestol markedly enhanced ABT-737-mediated apoptosis in Mcl-1-overexpressed Caki cells, human glioma U251MG cells, and human breast carcinoma MDA-MB231 cells. By contrast, co-treatment with ABT-737 and cafestol did not induce apoptosis in normal human skin fibroblast. Furthermore, combined treatment with cafestol and ABT-737 markedly reduced tumor growth compared with either drug alone in xenograft models. We found that cafestol inhibited Mcl-1 protein expression, which is important for ABT-737 resistance, through promotion of protein degradation. Moreover, cafestol increased Bim expression, and siRNA-mediated suppression of Bim expression reduced the apoptosis induced by cafestol plus ABT-737. Taken together, cafestol may be effectively used to enhance ABT-737 sensitivity in cancer therapy via downregulation of Mcl-1 expression and upregulation of Bim expression.

Abstract
AIMS Gallbladder (GB) cancer is a relatively uncommon gastrointestinal malignancy and is known to often result in unfavorable outcomes. Recent advances in aggressive surgical resection have improved the overall survival rate of patients with GB cancer. We aimed to evaluate the outcomes and prognostic factors of GB cancer following a surgical resection with curative intent. METHODS Between March 2001 and March 2009, 89 patients with GB cancer underwent surgical resection with curative intent at the National Cancer Center of Korea. We then conducted a retrospective analysis of clinicopathologic data. RESULTS Nineteen patients underwent simple cholecystectomy and 70 patients underwent extended cholecystectomy. Tumor-free resection margins were obtained in 84 cases. The 1-, 3- and 5-year disease-specific survival rates in the 89 patients were 85.8%, 68.0% and 64.1%, respectively. By multivariate analysis, only the T-category was significant (p < 0.001). The T-category showed a close correlation with all of the other histopathologic factors which were significant in univariate analysis. CONCLUSION The T-category of GB cancer represents not only the depth of the primary tumor but also the aggressiveness of its histopathologic nature.

Abstract
Abstract
Background
A consensus conference has recommended close observation of branch duct intraductal papillary mucinous neoplasms (BD-IPMNs) smaller than 30 mm, without symptoms or mural nodules. This study investigated whether these recommendations could be validated in a single-centre experience of BD-IPMNs.
Methods
Some 190 patients with radiological imaging or histological findings consistent with BD-IPMN were enrolled between 1998 and 2005. Those with less than 6 months' follow-up and no histological confirmation were excluded.
Results
BD-IPMN was diagnosed by computed tomography and pancreatography in 105 patients and pathologically in 85. Eighteen patients had adenoma, 53 borderline malignancy, five carcinoma in situ and nine invasive carcinoma. Findings associated with malignancy were the presence of radiologically suspicious features (P < 0·001) and a cyst size of at least 30 mm (P = 0·001). Had consensus guidelines been applied, 54 patients would have undergone pancreatic resection, whereas only 28 of these patients actually had a resection; 12 of the latter patients had a malignancy compared with none of the 26 patients who were treated conservatively.
Conclusion
A simple increase in cyst size is not a reliable predictor of malignancy. Observation is recommended for patients with a BD-IPMN smaller than 30 mm showing no suspicious features on imaging.

Abstract
BACKGROUND Previous research has generally found that variations in relatives' affective attitudes (expressed emotion; EE) towards a schizophrenic family member could not be accounted for by differences in the severity or form of the patient's symptomatology. These findings have been based on clinicians' ratings of psychopathology in patients. METHOD To approach the question from a different perspective, videotaped interactions between a patient and family members, obtained four to five weeks after hospital discharge, were coded for subclinical signs of psychopathology expressed by the patient. The Behavioral Subclinical Rating Scale (BSRS) was developed to compare subclinical levels of non-verbal and paralinguistic symptoms expressed by patients from both high- and low-EE families. RESULTS Highly significant differences were found in the BSRS data. Patients from high-EE families showed more hostile and unusual behaviour with relatives than those from low-EE homes, who, in contrast, showed more anxious behaviour. CONCLUSION These data suggest that a complex transactional model is necessary to understand how family attitudes evolve during the course of a relatives' schizophrenic disorder.
