OBJECTIVE: Tumor necrosis factor receptor-associated factor 6 (TRAF6) is an essential component of the signaling complex that mediates osteoclastogenesis. As an adaptor protein of E3 ligase function, TRAF6 regulates NF-κB signaling via TAK1 and I-κB kinase (IKK) activation. Here, we investigated novel mechanisms by which TRAF6 signaling is regulated under receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis. DESIGN: A yeast two-hybrid screen system identified cellular factors that interact with TRAF6...

Allogeneic hematopoietic stem cell transplantation (HSCT) can retard the progression of early infantile Krabbe disease (EIKD). Superior outcomes are achieved if HSCT is performed prior to the onset of symptoms, however little information is available about the long-term outcomes in surviving patients. We now describe functional outcomes in pre-symptomatic infants who underwent HSCT for EIKD at ≤2 months of life. Records of the 19 patients who underwent HSCT for EIKD at ≤2 months of age from 1996-2010 were reviewed...

The life-threatening group of irregular cardiac rhythmic disorders also known as Cardiac Arrhythmias (CA) are caused by mutations in highly conserved Calmodulin (CALM/CaM) genes. Herein, we present a multidimensional approach to diagnose changes in phenotypic, stability, and Ca2+ ion binding properties of CA-causing mutations. Mutation pathogenicity was determined by diverse computational machine learning approaches. We further modeled the mutations in 3D protein structure and analyzed residue level phenotype plasticity...

The most polarizable localized surface plasmon resonance (LSPR) longitudinal mode of anisotropic metallic nanoparticles, such as gold bipyramids (AuBPs), is of high prominence. This optical response has tremendous applications from spectroscopy to photonics and energy devices to sensing. In conventional LSPR-based sensing, broadening and asymmetry in peaks due to chemical and instrument noise hinder obtaining a precise insight on shift positions, accordingly limiting the effectiveness and impact of LSPR sensors...

OBJECTIVE: Lung cancer is the number one cancer in terms of both mortality and incidence. Cancer cells differ from normal cells in that they can reprogram their metabolism to support a rapid proliferation rate and alter oxidative phosphorylation processes toward lactic acid fermentation, even under aerobic conditions. Therefore we aimed to identify new compounds that might act as Pyruvate kinase M2 isoform (PKM2) activators and to investigate their anti-cancer efficacy in non-small cell lung cancer (NSCLC) cells...

INTRODUCTION: We present the Brain-Age Score (BAS) as a magnetic resonance imaging (MRI)-based index for Alzheimer's disease (AD). We developed a fully automated framework for estimating the BAS in healthy controls (HCs) and individuals with mild cognitive impairment (MCI) or AD, using MRI scans. METHODS: We trained the proposed framework using 385 HCs from the IXI and OASIS datasets and evaluated 146 HCs, 102 stable-MCI (sMCI), 112 progressive-MCI (pMCI), and 147 AD patients from the J-ADNI dataset...

BACKGROUND AND AIM: Chronic obstructive pulmonary disease (COPD) may be associated with worsening of cognitive performance. We studied patients with Alzheimer's disease (AD) with and without COPD, and we analyzed, in a retrospective way, clinical and neuropsychological variables to verify if COPD plays a pejorative role on cognitive or functional autonomy in patients with dementia. METHODS: We enrolled 23 adult patients (AD-COPD) with probable AD and COPD and 23 with AD only (AD-only); they were matched for sex, age, educational level, and Mini Mental State Examination (MMSE) at the disease onset...

PURPOSE: We aimed to assess the impact of implementing Edmonton Symptom Assessment System (ESAS) screening on health-related quality of life (HRQoL) and patient satisfaction with care (PSC) in ambulatory oncology patients. ESAS is now a standard of care in Ontario cancer centers, with the goal of improving symptom management in cancer patients, yet few studies examine impact of ESAS on patient outcomes. METHODS: We compared ambulatory oncology patients who were not screened prior to ESAS site implementation (2011-2012), to a similar group who were screened using ESAS after site implementation (2012-2013), to examine between-group differences in patient HRQoL, PSC outcomes, and supportive care needs (Supportive Care Service Survey)...

This study employed cell recycling, batch adaptation, cell mating and high throughput screening to select adapted Spathaspora passalidarum strains with improved fermentative ability.The most promising candidate, YK208-E11 (E11) showed a 3-fold increase in specific fermentation rate compared to the parental strain and an ethanol yield greater than 0.45 g/g substrate while co-utilizing cellobiose, glucose, and xylose. Further characterization showed that strain E11 also makes 40% less biomass compared to the parental strain when cultivated in rich media under aerobic conditions...

Faithful chromosome segregation depends on correct spindle microtubule-kinetochore attachment and requires certain spindle-associated proteins (SAPs) involved in regulating spindle dynamics and chromosome segregation. Little is known about the spindle-associated proteome in the early divergent Trypanosoma brucei and its roles in chromosome segregation. Here we report the identification of a cohort of divergent SAPs through localization-based screening and proximity-dependent biotin identification. We identified seven new SAPs and seventeen new nucleolar proteins that associate with the spindle, and demonstrated that the kinetochore protein KKIP4 also associates with the spindle...

Background & Aims: Effective therapeutic approaches are urgently required to tackle the alarmingly poor survival outcomes in esophageal adenocarcinoma (EAC) patients. EAC originates from within the intestinal-type metaplasia, Barrett's esophagus, a condition arising on a background of gastroesophageal reflux disease and associated inflammation. Methods: This study used a druggable genome small interfering RNA (siRNA) screening library of 6022 siRNAs in conjunction with bioinformatics platforms, genomic studies of EAC tissues, somatic variation data of EAC from The Cancer Genome Atlas data of EAC, and pathologic and functional studies to define novel EAC-associated, and targetable, immune factors...

Osteosarcoma (OS) cell lines are widely used in understanding the biological functions of cancer, identification and validation of therapeutic targets, as well as in vitro or in vivo preclinical drug screening. Here we report there is a frequent loss-of-function of polycomb repressive complex 2 (PRC2) in OS cell lines but it is rare in tumor samples based on genomic sequencing data, western blotting and immunohistochemistry analysis of H3K27me3. U2OS and 143B cell lines have a complete loss of function of PRC2 and several others have partial loss...

Over the past decade, therapies targeting the VEGF/VEGFR and mTOR pathways have served as the standard of care for the clinical management of renal cell carcinoma (RCC) patients. Albeit promising, these targeted drugs have attained only modest clinical benefits with limited prolonged progression-free survival. Therefore, alternative reasonable and applicable therapeutic approaches should be introduced to improve the clinical outcome of RCC patients. Methods: FDA approved kinase inhibitors were screened to evaluate their abilities to suppress the proliferation of RCC cells...

MyD88 is a cytoplasmic adaptor protein that plays a central role in signaling downstream of the TLRs and the IL1R superfamily. We previously demonstrated that MyD88 plays a critical role in EAE, the murine model of multiple sclerosis, and showed that the MyD88 BB-loop decoy peptide RDVLPGT ameliorates EAE. We now designed and screened a library of backbone cyclized peptides based on the linear BB loop peptide, to identify a metabolically stable inhibitor of MyD88 that retains the binding properties of the linear peptide...

Chromosome segregation depends on sister chromatid cohesion which is established by cohesin during DNA replication. Cohesive cohesin complexes become acetylated to prevent their precocious release by WAPL before cells have reached mitosis. To obtain insight into how DNA replication, cohesion establishment and cohesin acetylation are coordinated, we analysed the interaction partners of 55 human proteins implicated in these processes by mass spectrometry. This proteomic screen revealed that on chromatin the cohesin acetyltransferase ESCO2 associates with the MCM2-7 subcomplex of the replicative Cdc45-MCM-GINS helicase...

Phenylalkylamines, such as the plant compounds ephedrine and pseudoephedrine and the animal neurotransmitters dopamine and adrenaline, compose a large class of natural and synthetic molecules with important physiological functions and pharmaceutically valuable bioactivities. The final steps of ephedrine and pseudoephedrine biosynthesis in members of the plant genus Ephedra involve N -methylation of norephedrine and norpseudoephedrine, respectively. Here, using a plant transcriptome screen, we report the isolation and characterization of an N -methyltransferase (NMT) from Ephedra sinica able to catalyze the formation of (pseudo)ephedrine and other naturally occurring phenylalkylamines, including N -methylcathinone and N -methyl(pseudo)ephedrine...

Purpose: Childhood cancer survivors are at risk for anthracycline-related cardiac dysfunction, often developing at a time when they are least engaged in long-term survivorship care. New paradigms in survivorship care and chronic disease screening are needed in this population. We compared the accuracy of a novel handheld mHealth platform (Vivio) as well as echocardiography for assessment of cardiac function [left ventricular ejection fraction (EF)] in childhood cancer survivors with cardiac magnetic resonance (CMR) imaging (reference)...
