Abstract
Estrogen receptor-alpha positive (ER+) breast cancers comprise the majority of human breast cancers, but molecular mechanisms underlying this subtype of breast cancers remain poorly understood. Here, we show that ER+ mammary luminal tumors arising in Tip30−/−MMTV-Neu mice exhibited increased enrichment of luminal progenitor gene signature. Deletion of the Tip30 gene increased proportion of mammary stem and progenitor cell populations, and raised susceptibility to ER+ mammary luminal tumors in female Balb/c mice. Moreover, Tip30−/− luminal progenitors displayed increases in propensity to differentiate to mature ER+ luminal cells and FoxA1 expression. Knockdown of FoxA1 expression in Tip30−/− progenitors by shRNA specific for FoxA1 reduced their differentiation toward ER+ mature luminal cells. Taken together, our results suggest that TIP30 is a key regulator for maintaining ER+ and ER−luminal pools in the mammary luminal lineage, and loss of it promotes expansion of ER+ luminal progenitors and mature cells and ER+ mammary tumorigenesis.

Abstract
BACKGROUND The symptoms of major depression (MD) are clinically diverse. Do they form coherent factors that might clarify the underlying nature of this important psychiatric syndrome? METHOD Symptoms at lifetime worst depressive episode were assessed at structured psychiatric interview in 6008 women of Han Chinese descent, age ⩾30 years with recurrent DSM-IV MD. Exploratory factor analysis (EFA) and confirmatoryfactor analysis (CFA) were performed in Mplus in random split-half samples. RESULTS The preliminary EFA results were consistently supported by the findings from CFA. Analyses of the nine DSM-IV MD symptomatic A criteria revealed two factors loading on: (i) general depressive symptoms; and (ii) guilt/suicidal ideation. Examining 14 disaggregated DSM-IV criteria revealed three factors reflecting: (i) weight/appetite disturbance; (ii) general depressive symptoms; and (iii) sleep disturbance. Using all symptoms (n = 27), we identified five factors that reflected: (i) weight/appetite symptoms; (ii) general retarded depressive symptoms; (iii) atypical vegetative symptoms; (iv) suicidality/hopelessness; and (v) symptoms of agitation and anxiety. CONCLUSIONS MD is a clinically complex syndrome with several underlying correlated symptom dimensions. In addition to a general depressive symptom factor, a complete picture must include factors reflecting typical/atypical vegetative symptoms, cognitive symptoms (hopelessness/suicidal ideation), and an agitated symptom factor characterized by anxiety, guilt, helplessness and irritability. Prior cross-cultural studies, factor analyses of MD in Western populations and empirical findings in this sample showing risk factor profiles similar to those seen in Western populations suggest that our results are likely to be broadly representative of the human depressive syndrome.

Abstract
1. This study was conducted to determine the effects of different dietary fat sources on growth performance, tibia fatty acids and biomarkers of bone metabolism in broilers. 2. One-d-old commercial Arbor Acres broilers were fed with a maize-soya bean basal diet for 42 d, supplemented with oils according to the following 5 treatments: lard (lard group); linseed oil (linseed oil group); palm oil (palm oil group); linseed oil + palm oil (60:40 or 40:60 w/w, LP-1 group and LP-2 group, respectively). 3. No significant differences in weight gain, feed intake and gain/feed ratio were observed between the lard and linseed oil groups. Birds fed on palm oil had significantly greater weight gain and feed intake than those fed on lard or linseed oil. Growth performance in LP-1 and LP-2 was significantly greater than that of single-oil groups. 4. Tibia growth and bone characteristics were not influenced by supplementation with lard, linseed oil, or palm oil alone, but broilers fed on a mixture of fats had significantly greater tibia weight and length compared to broilers fed on linseed oil. Bone mineral density in tibia was significantly increased in LP-1 and LP-2 groups. 5. Supplementation of linseed oil alone or in combination with palm oil enhanced apparent digestibility of calcium, reduced serum calcium and increased tibia calcium concentrations. Moreover, supplementation with linseed oil alone or in combination with palm oil had a positive effect on biomarkers of bone growth. 6. The combination of linseed and palm oils was beneficial for growth performance, tibia growth and biomarkers of bone metabolism.

Abstract
Exportin 4 (XPO4) is a novel identified candidate tumour-suppressor gene involved in the pathogenesis of hepatocellular carcinoma (HCC). This study was aimed to determine the clinical features of XPO4 mRNA expression and promoter methylation status in peripheral blood mononuclear cells (PBMCs) of patients with chronic hepatitis B virus (HBV) infection. PBMCs were isolated from 44 HCC, 38 liver cirrhosis (LC), 34 chronic hepatitis B (CHB) patients and 17 healthy controls (HCs). The mRNA level and promoter methylation status of XPO4 were determined by quantitative real-time RT-PCR and methylation-specific PCR, respectively. XPO4 mRNA level of HCC patients was significantly lower compared with LC and CHB patients as well as HCs (all P < 0.01, respectively), and significant differences of the XPO4 mRNA level were found in LC and CHB group than in HCs (LC vs HCs, P < 0.01; CHB vs HCs, P < 0.05). Methylation rate of XPO4 promoter was significantly increased in patients with HCC than in patients with CHB and HCs (both P < 0.05). DNA methylation pattern was responsible for the suppression of XPO4 transcription in the progression of HBV infection (P = 0.000). Furthermore, AFP level was significantly higher in HCC patients with XPO4 methylation than in those without methylation ((8702 ± 15635) μm vs (1052 ± 5370) μm, P < 0.05). In conclusion, transcription of XPO4 gene was gradually decreased and methylation rate of XPO4 promoter was increased with the progression of HBV infection. Methylation status of XPO4 in PBMCs tended to be a noninvasive biomarker to predict HCC and the progression of HBV infection.

Abstract
Aging refers to the physical and functional decline of the tissues over time that often leads to age-related degenerative diseases. Accumulating evidence implicates that the senescence of neural stem cells (NSCs) is of paramount importance to the aging of central neural system (CNS). However, exploration of the underlying molecular mechanisms has been hindered by the lack of proper aging models to allow the mechanistic examination within a reasonable time window. In the present study, we have utilized a hydroxyurea (HU) treatment protocol and effectively induced postnatal subventricle NSCs to undergo cellular senescence as determined by augmented senescence-associated-β-galactosidase (SA-β-gal) staining, decreased proliferation and differentiation capacity, increased G0/G1 cell cycle arrest, elevated reactive oxygen species (ROS) level and diminished apoptosis. These phenotypic changes were accompanied by a significant increase in p16, p21 and p53 expression, as well as a decreased expression of key proteins in various DNA repair pathways such as xrcc2, xrcc3 and ku70. Further proteomic analysis suggests that multiple pathways are involved in the HU-induced NSC senescence, including genes related to DNA damage and repair, mitochondrial dysfunction and the increase of ROS level. Intriguingly, compensatory mechanisms may have also been initiated to interfere with apoptotic signaling pathways and to minimize the cell death by downregulating Bcl2-associated X protein (BAX) expression. Taken together, we have successfully established a cellular model that will be of broad utilities to the molecular exploration of NSC senescence and aging.

Abstract
We report a new design of carbon nanotube (CNT) resonator, whose resonance frequency can be tuned not only transversally by a gate voltage, but also by the axial strain applied through directly pulling the CNT. The resonators are fabricated from individual suspended single-walled CNT (SWCNT) in situ inside a scanning electron microscope. The resonance frequency of a SWCNT resonator can be tuned by more than 20 times with an increase of quality factor when the axial strain of the SWCNT is only increased from nearly zero to 2% at room temperature. The transversal gate-tuning ability is found to be weaker than the axial-tuning ability and decrease with increasing the axial strain. The gate voltage can hardly tune the resonance frequency when the initial axial strain is larger than 0.35% and the CNT acts like a tied string. The relationship among resonance frequency, gate voltage, and initial axial strain of the CNT obtained presently will allow for the designs of CNT resonators with high frequency and large tuning range. The present resonator also shows ultrahigh sensitivity in displacement and force detection, with a resolution being better than 2.4 pm and 0.55 pN, respectively.

Abstract
BACKGROUND AND PURPOSE Recent studies found that microembolic signals (MESs) could be detected by transcranial Doppler in patients with moyamoya disease. However, the clinical significance of MESs in moyamoya disease remains unclear. Our aim was to investigate whether the MESs could predict cerebral ischaemic events in patients with moyamoya disease. METHODS Fifty-four consecutive patients with moyamoya disease were recruited. MESs were monitored by transcranial Doppler for 30 min in the bilateral middle cerebral arteries of each patient on admission. Patients were followed up for 1 year. The primary end-point was cerebral ischaemic events including stroke and transient ischaemic attack (TIA). RESULTS MESs were detected in 11 (20.4%) patients, with a frequency of 11 (10.2%) in 108 hemispheres. Logistic regression analysis revealed that previous ischaemic events within 3 months were associated with the presence of MESs (odds ratio 4.41, 95% CI 1.11-17.59). During a median follow-up of 384 days, 14 (13.0%) hemispheres had ischaemic events (seven strokes and seven TIAs). Cox regression showed that the hazard ratio for the risk of new ischaemic stroke and TIA in the hemispheres with MESs was 6.84 (95% CI 1.82-25.66) compared with those without, and 10.61 (95% CI 1.66-67.70) for ischaemic stroke alone, after controlling for age, sex, presence of ischaemic events at baseline, Suzuki stages and revascularization surgery. CONCLUSIONS In patients with moyamoya disease, the presence of MESs is associated with recent ischaemic symptoms and independently predicts cerebral ischaemic events. MES detection may be of potential clinical value in the management of patients with moyamoya disease.

Abstract
Excitatory transmission in the brain is commonly mediated by the α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors. In amyotrophic lateral sclerosis (ALS), AMPA receptors allow cytotoxic levels of calcium into neurons, contributing to motor neuron injury. We have previously shown that oculomotor neurons resistant to the disease process in ALS show reduced AMPA-mediated inward calcium currents compared with vulnerable spinal motor neurons. We have also shown that PTEN (phosphatase and tensin homolog deleted on chromosome 10) knockdown via siRNA promotes motor neuron survival in models of spinal muscular atrophy (SMA) and ALS. It has been reported that inhibition of PTEN attenuates the death of hippocampal neurons post injury by decreasing the effective translocation of the GluR2 subunit into the membrane. In addition, leptin can regulate AMPA receptor trafficking via PTEN inhibition. Thus, we speculate that manipulation of AMPA receptors by PTEN may represent a potential therapeutic strategy for neuroprotective intervention in ALS and other neurodegenerative disorders. To this end, the first step is to establish a fibroblast-iPS-motor neuron in vitro cell model to study AMPA receptor manipulation. Here we report that iPS-derived motor neurons from human fibroblasts express AMPA receptors. PTEN depletion decreases AMPA receptor expression and AMPA-mediated whole-cell currents, resulting in inhibition of AMPA-induced neuronal death in primary cultured and iPS-derived motor neurons. Taken together, our results imply that PTEN depletion may protect motor neurons by inhibition of excitatory transmission that represents a therapeutic strategy of potential benefit for the amelioration of excitotoxicity in ALS and other neurodegenerative disorders.

Abstract
PURPOSE To create a patient respiratory management system and patient self-practice tool using the Wii remote, a widely available consumer hardware product. METHODS The Wii remote (Wiimote) (Nintendo, Redmond, WA) contains an infrared (IR) camera that can track up to four spots whose coordinates are reported to a host computer via Bluetooth. The Wiimote is capable of tracking a fiducial box currently used by a commercial monitoring system [Real-time Position Management(TM) (RPM) system, Varian Associates, Palo Alto, CA], if the correct IR source is used. The authors validated the Wiimote tracking by comparing the amplitude and frequency of signals among those reported by Wiimote with known movements from an inhouse servo-driven respiratory simulator, as well as with those measured using the RPM. The simulator comparison was done using standard sinusoid signals with amplitude of 2.0 cm as well as recorded patient respiratory traces. The RPM comparisons were done by simultaneously recording the RPM reflective box position with the Wiimote and the RPM. Timing was compared between these two systems by using the digital beam-on signal from the CT scanner, for the 4DCT to synchronize these acquisitions. RESULTS The data acquisition rate from the Wiimote was 100.0 ± 0.4 Hz with a version 2.1 Bluetooth adaptor. The standard deviation of the height of the motion extrema was 0.06 and 1.1 mm when comparing those measured by the Wiimote and the servomotor encoder for standard sinusoid signal and prerecorded patient respiratory signal, respectively. The standard deviation of the amplitude of motion extrema between the Wiimote and RPM was 0.9 mm and the timing difference was 253 ms. CONCLUSION The performance of Wiimote shows promise for respiratory monitoring for its faster sampling rate as well as the potential optical and GPU abilities. If used with care it can deliver reasonable spatial and temporal accuracy.

Abstract
BACKGROUND AND PURPOSE Data on the possible association between cardiac right-to-left shunt (RLS) and cryptogenic stroke are lacking in Asians. RLS and its subtypes in Chinese cryptogenic stroke patients were investigated. METHODS Patients (n = 153, mean age 42 ± 10 years, 81 male) with cryptogenic stroke from four medical centers in China and 135 healthy volunteers (mean age 34 ± 8 years, 54 male) were recruited. Contrast transcranial Doppler was used to assess the prevalence of RLS. A three-level RLS categorization was applied as follows: none, 0 microbubbles (MBs); small, 1-25 MBs; and large, >25 MBs. RLS was considered latent if it occurred only after the Valsalva maneuver or permanent when it occurred also during normal respiration. RESULTS Overall, RLS (P = 0.02), large RLS (P < 0.001) and permanent RLS (P = 0.02) were more frequently detected in patients with cryptogenic stroke than in healthy volunteers. The prevalences of small RLS and latent RLS in the two groups were similar (22% vs. 21% and 11% vs. 10%, respectively). The proportion of large RLSs amongst the subjects with RLS was much higher in the patient group than in healthy volunteers (45% vs. 18%, P < 0.001), whilst the proportion of permanent RLS was similar (72% vs. 64%, P = 0.11). Most large RLSs in the patient group (22/27, 81%) were permanent RLSs. CONCLUSIONS Cardiac RLS is associated with cryptogenic stroke in Chinese. However, the higher prevalence of overall RLS in the patient group was mainly due to the increased proportion of large RLSs. The results only support large RLSs as a pathological condition.

Abstract
Aberrant immunity response contributes to the pathogenesis of acute-on-chronic hepatitis B liver failure. Tumour necrosis factor-α-induced protein-8 like-2 (TIPE2) is a recently identified molecular to maintain immune homoeostasis, but its role in acute-on-chronic hepatitis B liver failure (ACHBLF) is unknown. We detected TIPE2 mRNA levels in peripheral blood mononuclear cells (PBMCs) from 56 patients with ACHBLF, 60 chronic hepatitis B patients, 24 healthy controls and analysed its role in disease severity and prognosis. TIPE2 mRNA expression in patients with ACHBLF was higher than that of patients with chronic infection or healthy controls. In patients with ACHBLF, TIPE2 mRNA level was positively correlated with serum total bilirubin, international normalized ratio and model for end-stage liver disease scores. Furthermore, the level of TIPE2 mRNA was significantly higher in nonsurvivors than survivors in patients with ACHBLF. The mRNA level of TIPE2 gradually decreased week by week in survivors accompanied by recovery from patients with ACHBLF, while its expression sustained at high levels in nonsurvivors. TIPE2 mRNA level after lipopolysaccharide (LPS) stimulation ex vivo in patients with ACHBLF was higher compared with controls and patients with chronic infection. Meanwhile, cytokines ex vivo secreted were measured as a marker of immune activation. After LPS stimulation, interleukin (IL)-6 and tumour necrosis factor (TNF)-α mRNA expression were reduced in patients with ACHBLF, and a significantly negative correlation was found between TIPE2 and TNF-α mRNA levels. In conclusion, our results identified the potential role of TIPE2 in predicting disease progression and prognosis in patients with ACHBLF by negative regulating of cell-mediated immunity.

Abstract
The dynamic properties of the dipolar magnet CsGd(MoO4)2 have been studied. The frequency and temperature dependence of the AC susceptibility investigated in the paramagnetic region above 2 K revealed the co-existence of magnetic field induced slow and fast relaxation channels with a timescale differing by three orders of magnitude. The slow relaxation is determined by the properties of the first coordination sphere of the Gd(3+) ion and has the character of a two-phonon Orbach process. The fast relaxation is potentially attributed to a two-phonon Raman process realized via a localized phonon mode associated with the layered crystal structure. The temperature dependence of the phonon mean free path in zero magnetic field indicates significant phonon scattering below 1 K resulting from the combined effect of magnetic correlations and the scattering of dominant phonons with energies corresponding to the crystal-field levels.

Abstract
Type 2 diabetes (T2D) and male gender are associated with hepatocellular carcinoma (HCC) development. We demonstrate that heterozygous deletion of the Ncoa5 gene causes spontaneous development of HCC exclusively in male mice. Tumor development is preceded by increased interleukin-6 (IL-6) expression, early-onset glucose intolerance, and progressive steatosis and dysplasia in livers. Blockading IL-6 overexpression averts glucose intolerance and partially deters HCC development. Moreover, reduced NCOA5 expression is associated with a fraction of human HCCs and HCCs with comorbid T2D. These findings suggest that NCOA5 is a haploinsufficient tumor suppressor and that NCOA5 deficiency increases susceptibility to both glucose intolerance and HCC, partially by increasing IL-6 expression. Thus, our findings open additional avenues for developing therapeutic approaches to combat these diseases.

MicroRNA-30a-3p inhibits tumor proliferation, invasiveness and metastasis and is downregulated in hepatocellular carcinoma. Eur J Surg Oncol 2013; 40:1586-94. [PMID: 24290372 DOI: 10.1016/j.ejso.2013.11.008] [Citation(s) in RCA: 58] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2012] [Revised: 10/18/2013] [Accepted: 11/01/2013] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND MicroRNAs (miRNAs) are small non-coding RNAs that regulate physiological and pathological processes by suppressing target gene expression. Altered expression of miR-30a-3p has been demonstrated in several cancers. However, little about how miR-30a-3p functions in these cancers has been reported, and the role of miR-30a-3p in hepatocellular carcinoma (HCC) is unknown. The purpose of this study was to identify the role and underlying molecular mechanism of action of miR-30a-3p in HCC. METHODS A total of 110 HCC patients, primarily treated by surgical removal of tumors, were involved in the study. HCC cell line Bel-7402 was selected to characterize the function of miR-30a-3p in vitro. RESULTS Our results showed that in 83.6% of the 110 HCC patients, expression of miR-30a-3p was significantly downregulated (P < 0.0001) in tumors compared to adjacent normal tissues. In a clinicopathological correlation analysis, downregulation of miR-30a-3p correlated with a significantly higher incidence of portal vein tumor thrombus (PVTT, P = 0.009). Moreover, miR-30a-3p markedly inhibited the invasion and migration of Bel-7402 HCC cells in vitro. Furthermore, miR-30a-3p overexpression had an inhibitory effect on cell proliferation, induced apoptosis and increased arrest of cells in the S phase. We further demonstrated that miR-30a-3p regulates HCC cell function by a mechanism involving reduced vimentin and MMP3 expression and restoration of E-cadherin expression. CONCLUSIONS our data suggest that miR-30a-3p is downregulated in HCC and acts as a tumor suppressor in vitro. Regulation of vimentin, E-cadherin and MMP3 by miR-30a-3p suggests a useful therapeutic strategy for tumors with reduced miR-30a-3p expression.

Abstract
BACKGROUND Previous studies support Beck's cognitive model of vulnerability to depression. However, the relationship between his cognitive triad and other clinical features and risk factors among those with major depression (MD) has rarely been systematically studied. METHOD The three key cognitive symptoms of worthlessness, hopelessness and helplessness were assessed during their lifetime worst episode in 1970 Han Chinese women with recurrent MD. Diagnostic and other risk factor information was assessed at personal interview. Odds ratios (ORs) were calculated by logistic regression. RESULTS Compared to patients who did not endorse the cognitive trio, those who did had a greater number of DSM-IV A criteria, more individual depressive symptoms, an earlier age at onset, a greater number of episodes, and were more likely to meet diagnostic criteria for melancholia, postnatal depression, dysthymia and anxiety disorders. Hopelessness was highly related to all the suicidal symptomatology, with ORs ranging from 5.92 to 6.51. Neuroticism, stressful life events (SLEs) and a protective parental rearing style were associated with these cognitive symptoms. CONCLUSIONS During the worst episode of MD in Han Chinese women, the endorsement of the cognitive trio was associated with a worse course of depression and an increased risk of suicide. Individuals with high levels of neuroticism, many SLEs and high parental protectiveness were at increased risk for these cognitive depressive symptoms. As in Western populations, symptoms of the cognitive trio appear to play a central role in the psychopathology of MD in Chinese women.

Abstract
UNLABELLED Both Bacillus subtilis and harpins stimulate plant growth and defence against various plant pathogens. In this study, B. subtilis 168 and two derivatives, surfactin producer OKB105 and combined surfactin and HpaGX ooc producer OKBHF, were applied to tomato plants to investigate the mechanisms underlying this effect. To evaluate colonization ability, strains were labelled with green fluorescent protein (GFP). Although biofilm distribution of the three strains was similar on root surfaces, Colonization populations of the two surfactin producers were approximately 2- to 3-fold higher than that of strain 168, and this was accompanied by significantly increased tomato growth. These results suggest that efficient colonization, possibly facilitated by surfactin production, enhanced the efficiency of plant growth promotion by B. subtilis. All three B. subtilis treatments caused plants to have less severe disease symptoms after inoculation with Ralstonia solanacearum, with plants treated with OKBHF being the most resistant, suggesting that hpaGX ooc improves biocontrol efficiency of B. subtilis. Analysis of defence-related genes showed a synergistic effect of HpaGX ooc on B. subtilis enhancement of the expression of the pathogenesis-related genes PR1b1 and PR-P2. In contrast, expression of the defence-related genes PINI and PINII was suppressed. SIGNIFICANCE AND IMPACT OF THE STUDY Bacillus subtilis and harpins are biological control agents with respective advantages. In this study, combinations of the both were applied to tomato in the form of hpaGX ooc -expressing B. subtilis, showed much better effects on resistance to wilt disease, and equivalent effects on plant growth promotion compared with the progenitor strain have a great potential in agricultural use.

Abstract
An important element of radiation treatment planning for cancer therapy is the selection of beam angles (out of all possible coplanar and non-coplanar angles in relation to the patient) in order to maximize the delivery of radiation to the tumor site and minimize radiation damage to nearby organs-at-risk. This category of combinatorial optimization problem is particularly difficult because direct evaluation of the quality of treatment corresponding to any proposed selection of beams requires the solution of a large-scale dose optimization problem involving many thousands of variables that represent doses delivered to volume elements (voxels) in the patient. However, if the quality of angle sets can be accurately estimated without expensive computation, a large number of angle sets can be considered, increasing the likelihood of identifying a very high quality set. Using a computationally efficient surrogate beam set evaluation procedure based on single-beam data extracted from plans employing equallyspaced beams (eplans), we have developed a global search metaheuristic process based on the nested partitions framework for this combinatorial optimization problem. The surrogate scoring mechanism allows us to assess thousands of beam set samples within a clinically acceptable time frame. Tests on difficult clinical cases demonstrate that the beam sets obtained via our method are of superior quality.
