Aurora A kinase activates YAP signaling in triple-negative breast cancer.

The Yes-associated protein (YAP) is an effector that transduces the output of the Hippo pathway to transcriptional modulation. Considering the role of YAP in cancers, this protein has emerged as a key node in malignancy development. In this study, we determined that Aurora A kinase acts as a positive regulator for YAP-mediated transcriptional machinery.

Increased BDNF levels after electroconvulsive therapy in patients with major depressive disorder: A meta-analysis study.

Objective: We performed a systematic review and meta-analysis to estimate brain-derived neurotrophic factor (BDNF) level in patients with major depressive disorder (MDD) after electroconvulsive therapy (ECT).

Method: A comprehensive search of the Cochrane Library, MEDLINE, LILACS, Grey literature, and EMBASE was performed for papers published from January 1990 to April 2016. The following key terms were searched: "major depressive disorder", "unipolar depression", "brain-derived neurotrophic factor", and "electroconvulsive therapy".

Stat3 contributes to cancer progression by regulating Jab1/Csn5 expression.

Our previous studies demonstrated that Jab1/Csn5 overexpression is correlated with low survival rates in cancer patients, including nasopharyngeal carcinoma (NPC), breast cancer and hepatocellular carcinoma, and contributes to NPC's resistance to radiotherapy and cisplatin by regulating DNA damage and repair pathways. However, the molecular mechanism by which Jab1/Csn5 expression is upregulated in NPCs has yet to be determined. In the present study, we identified the upstream regulator of Jab1/Csn5 expression and demonstrated its role in intrinsic resistance of NPC cells to treatment with cisplatin.

ZNF217/ZFP217 Meets Chromatin and RNA.

The Kruppel-like transcription factor zinc finger protein (ZNF)217 (mouse homolog ZFP217) contributes to tumorigenesis by dysregulating gene expression programs. The newly discovered molecular function of ZFP217 in controlling N6-methyladenosine (mA) deposition in embryonic stem cells (ESCs) sheds new light on the role of this transcription factor in tumor development.

Inhibition of VEGF165/VEGFR2-dependent signaling by LECT2 suppresses hepatocellular carcinoma angiogenesis.

Hepatocellular carcinoma (HCC) relies on angiogenesis for growth and metastasis. Leukocyte cell-derived chemotaxin 2 (LECT2) is a cytokine and preferentially expressed in the liver. Previous studies have found that LECT2 targets to both immune and tumor cells to suppress HCC development and vascular invasion.

Loss of ARID1A expression leads to sensitivity to ROS-inducing agent elesclomol in gynecologic cancer cells.

Inactivating mutations in ARID1A are found in a broad spectrum of cancer types, with the highest frequency in gynecologic cancers. However, therapeutic strategies targeting ARID1A-mutant cancer cells remain limited. In this study, we aimed to identify drugs sensitivities in ARID1A-mutant cancer cell lines.

ZMYND8 Reads the Dual Histone Mark H3K4me1-H3K14ac to Antagonize the Expression of Metastasis-Linked Genes.

Histone acetylation, including acetylated H3K14 (H3K14ac), is generally linked to gene activation. Monomethylated histone H3 lysine 4 (H3K4me1), together with other gene-activating marks, denotes active genes. In contrast to usual gene-activating functions of H3K14ac and H3K4me1, we here show that the dual histone modification mark H3K4me1-H3K14ac is recognized by ZMYND8 (also called RACK7) and can function to counteract gene expression.

ASCT2 (SLC1A5) is an EGFR-associated protein that can be co-targeted by cetuximab to sensitize cancer cells to ROS-induced apoptosis.

Therapeutic targeting of ASCT2, a glutamine transporter that plays a major role in glutamine uptake in cancer cells, is challenging because ASCT2 also has a biological role in normal tissues. In this study, we report our novel finding that ASCT2 is physically associated in a molecular complex with epidermal growth factor receptor (EGFR), which is often overexpressed in human head and neck squamous cell carcinoma (HNSCC). Furthermore, we found that ASCT2 can be co-targeted by cetuximab, an EGFR antibody approved for treating metastatic HNSCC.

Predictors of survival in patients with sarcoma admitted to the intensive care unit.

Background: Advances in treatment of sarcoma patients has prolonged survival but has led to increased disease- or treatment-related complications resulting in greater number of admissions to the intensive care unit (ICU). Survival and long-term outcome information about such critically ill patients with sarcoma is unknown.

Methods: The primary objective of the study was to determine the ICU and post-ICU survival rates of critically ill sarcoma patients.

Effect of alcohol and illicit substance use on verbal memory among individuals with bipolar disorder.

Background: Cognitive impairment is a well-established feature of bipolar disorder (BD). Comorbid BD and substance use leads to poor psychosocial and clinical outcomes. However, knowledge on the neurocognitive functioning of individuals with dual diagnosis is limited.

Dual-Energy Computed Tomography for the Characterization of Intracranial Hemorrhage and Calcification: A Systematic Approach in a Phantom System.

Objective: The aim of this study was to develop a diagnostic framework for distinguishing calcific from hemorrhagic cerebral lesions using dual-energy computed tomography (DECT) in an anthropomorphic phantom system.

Materials And Methods: An anthropomorphic phantom was designed to mimic the CT imaging characteristics of the human head. Cylindrical lesion models containing either calcium or iron, mimicking calcification or hemorrhage, respectively, were developed to exhibit matching, and therefore indistinguishable, single-energy CT (SECT) attenuation values from 40 to 100 HU.

Mitochondrial dysfunction in bipolar disorder: Evidence, pathophysiology and translational implications.

Bipolar disorder (BD) is a chronic psychiatric illness characterized by severe and biphasic changes in mood. Several pathophysiological mechanisms have been hypothesized to underpin the neurobiology of BD, including the presence of mitochondrial dysfunction. A confluence of evidence points to an underlying dysfunction of mitochondria, including decreases in mitochondrial respiration, high-energy phosphates and pH; changes in mitochondrial morphology; increases in mitochondrial DNA polymorphisms; and downregulation of nuclear mRNA molecules and proteins involved in mitochondrial respiration.

Neurochemical correlation between major depressive disorder and neurodegenerative diseases.

Major depressive disorder (MDD) is one of the most prevalent and life-threatening forms of mental illnesses affecting elderly people and has been associated with poor cognitive function. Recent evidence suggests a strong relationship between MDD and neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), Amyotrophic Lateral Sclerosis (ALS), as well as natural processes of aging. Changes in the neuroplasticity, morphology, and neurotransmission in the brain are seem to be associated to both, MDD and neurodegenerative diseases.

Transglutaminase is a Critical Link Between Inflammation and Hypertension.

Background: The pathogenesis of essential hypertension is multifactorial with different underlying mechanisms contributing to disease. We have recently shown that TNF superfamily member 14 LIGHT (an acronym for homologous to lymphotoxins, exhibits inducible expression, and competes with herpes simplex virus glycoprotein D for herpes virus entry mediator, a receptor expressed by T lymphocytes, also known as TNFSF14) induces hypertension when injected into mice. Research reported here was undertaken to examine the role of transglutaminase (TGase) in LIGHT-induced hypertension.

Depression-Like Adult Behaviors may be a Long-Term Result of Experimental Pneumococcal Meningitis in Wistar Rats Infants.

Pneumococcal meningitis is a life-threatening infection of the central nervous system (CNS) with a high mortality rate. In addition to causing severe neurological sequelae infectious diseases of the CNS can play a significant role in the pathogenesis of neuropsychiatric disorders. In this study infant Wistar rats, postnatal day 11, received intracerebroventricular (i.

Platelet-Related Variants Identified by Exomechip Meta-analysis in 157,293 Individuals.

Platelet production, maintenance, and clearance are tightly controlled processes indicative of platelets' important roles in hemostasis and thrombosis. Platelets are common targets for primary and secondary prevention of several conditions. They are monitored clinically by complete blood counts, specifically with measurements of platelet count (PLT) and mean platelet volume (MPV).

Insights into the development and regulation of T follicular helper cells.

T follicular helper (Tfh) cells are specialized subset of T helper (Th) cells necessary for germinal center reaction, affinity maturation and the differentiation of germinal center B cells to antibody-producing plasma B cells and memory B cells. The differentiation of Tfh cells is a multistage, multifactorial process involving a variety of cytokines, surface molecules and transcription factors. While Tfh cells are critical components of protective immune responses against pathogens, regulation of these cells is crucial to prevent autoimmunity and airway inflammation.

The role of DNA methylation in the pathophysiology and treatment of bipolar disorder.

Bipolar disorder (BD) is a multifactorial illness thought to result from an interaction between genetic susceptibility and environmental stimuli. Epigenetic mechanisms, including DNA methylation, can modulate gene expression in response to the environment, and therefore might account for part of the heritability reported for BD. This paper aims to review evidence of the potential role of DNA methylation in the pathophysiology and treatment of BD.

Outside the p53 RING: Transcription Regulation by Chromatin-Bound MDM2.

Evidence mounts, via two studies published in Molecular Cell (Riscal et al., 2016; Wienken et al., 2016), that chromatin-bound MDM2 impacts pluripotency and metabolism to promote survival and proliferation of cancer cells, independently of p53 degradation.

TRIM-ing Ligand Dependence in Castration-Resistant Prostate Cancer.

Prostate cancer is lethal when tumors evolve to activate androgen receptor signaling, which circumvents ligand-deprivation therapy. In this issue of Cancer Cell, Groner et al. show that histone reader and transcription co-regulator TRIM24 occupies a central role in this evolution, nominating inhibitors of TRIM24's bromodomain as a new therapeutic avenue.

Fast range measurement of spot scanning proton beams using a volumetric liquid scintillator detector.

Accurate confirmation and verification of the range of spot scanning proton beams is crucial for correct dose delivery. Current methods to measure proton beam range using ionization chambers are either time-consuming or result in measurements with poor spatial resolution. The large-volume liquid scintillator detector allows real-time measurements of the entire dose profile of a spot scanning proton beam.

The potential association between obesity and bipolar disorder: A meta-analysis.

Background: Several epidemiological studies have found that the prevalence of bipolar disorder (BD) is significantly higher in obese population than non-obese population. However, no meta-analysis has been published to quantitatively summarize the related literature.

Methods: In this study, we conducted a meta-analysis to explore the association between obesity and BD by combining 9 cross-sectional studies with a total of 12,259 BD cases and 615,490 non-BD controls.

Characterizing proton-activated materials to develop PET-mediated proton range verification markers.

Conventional proton beam range verification using positron emission tomography (PET) relies on tissue activation alone and therefore requires particle therapy PET whose installation can represent a large financial burden for many centers. Previously, we showed the feasibility of developing patient implantable markers using high proton cross-section materials ((18)O, Cu, and (68)Zn) for in vivo proton range verification using conventional PET scanners. In this technical note, we characterize those materials to test their usability in more clinically relevant conditions.

Isolation, identification, and characterization of novel nanovesicles.

Extracellular microvesicles (EVs) have been recognized for many potential clinical applications including biomarkers for disease diagnosis. In this study, we identified a major population of EVs by simply screening fluid samples with a nanosizer. Unlike other EVs, this extracellular nanovesicle (named HG-NV, HG-NV stands for HomoGenous nanovesicle as well as for Huang-Ge- nanovesicle) can be detected with a nanosizer with minimal in vitro manipulation and are much more homogenous in size (8-12 nm) than other EVs.
