The translationally controlled tumor protein (TCTP) is a family of abundant and ubiquitous proteins involved in several important primary functions. Cucumbers harbor two TCTP genes, CsTCTP1 and CsTCTP2; however, their functional roles remain unclear. In this study, we isolated CsTCTP1 and CsTCTP2 (XP-004134215 and XP-004135602, respectively) promoters, full-length cDNA and genomic sequences from Cucumis sativus. Bioinformatics analysis, containing cis-acting elements, structural domains, phylogenetic tree and conserved motifs, suggested the conservation and divergence of CsTCTP1 and CsTCTP2, thus providing knowledge regarding their functions...

Pulmonary artery hypertension (PAH) is characterized by structural changes in pulmonary arteries. Increased numbers of cells expressing α-smooth muscle actin (α-SMA) is a nearly universal finding in the remodeled artery. It has been confirmed endothelial-to-mesenchymal transition (EndoMT) may be a source of those α-SMA-expressing cells. In addition, the EndoMT is reversible. Here, we show that under hypoxia, the expression of bone morphogenetic protein 7 (BMP-7) was decreased both in vivo and in vitro. We also found that under normoxia, BMP-7 deficiency induced spontaneous EndoMT and cell migration...

Aging stem cells lose the capacity to properly respond to injury and regenerate their residing tissues. Here, we utilized the ability of Drosophila melanogaster germline stem cells (GSCs) to survive exposure to low doses of ionizing radiation (IR) as a model of adult stem cell injury and identified a regeneration defect in aging GSCs: while aging GSCs survive exposure to IR, they fail to reenter the cell cycle and regenerate the germline in a timely manner. Mechanistically, we identify foxo and mTOR homologue, Tor as important regulators of GSC quiescence following exposure to ionizing radiation...

Type 2 diabetes mellitus is characterized by insulin resistance. However, the complete molecular mechanism remains unclear. In this study, zebrafish were fed a long-term high-fat diet to induce type 2 diabetes, which resulted in a higher body weight, body mass index, more lipid vacuoles in liver, increased insulin transcription level in liver, brain and muscle, and high fasting blood glucose in the high-fat diet zebrafish. Oppositely, the transcription levels of insulin substrate-2 and glucose transporter 2 were significantly decreased, indicating insulin signaling pathway and glucose transport impaired in the insulin-targeting tissues...

Congenital aniridia is a rare panocular disease caused by fundamental disturbances in the development of the eye, characterized primarily by hypoplasia of the iris and the retinal fovea. Severe secondary complications such as keratopathy, cataract, and glaucoma are common and often lead to considerable visual impairment or blindness. Many complications in aniridia patients are difficult to treat and present a challenge for the ophthalmologist. Increasingly, associated non-ocular features of the disease are also being recognised...

Tumor associated macrophages (TAM) resemble M2 macrophages, promote tumor invasion and show strong expression of CD163 in breast cancer. We here investigated the association between CD163 positive macrophages and vascular invasion, molecular subgroups, mode of detection, and patient outcome. We performed a population-based, retrospective study of invasive breast cancer from the Norwegian Breast Cancer Screening Programme in Vestfold County (2004-2009), including 200 screen-detected and 82 interval cancers. Immunohistochemically CD163 positive macrophages were counted in the most active areas (hot-spots) and dichotomized as high (upper quartile) and low counts...

BACKGROUND: Vitamin-D deficiency has been linked with impaired development in animal studies; however, the evidence from human studies is scanty. Evidence as to whether vitamin-D deficiency during early childhood affects growth is also limited and conflicting. We examined the extent to which vitamin-D deficiency (<10 ng/ml) is associated with neurodevelopment and physical growth in young children. METHODS: We used data from a randomized controlled trial (RCT) of daily folic acid and/ or vitamin B12 supplementation for six months in children aged 6 to 30 months conducted in Delhi, India...

In nutrient restricted environments, the yeast endosulfines Igo1/2 are activated via TORC1 inhibition and function critically to initiate and coordinate the cellular stress response that promotes survival. We examined expression of αEnsa, the mammalian homolog of yeast endosulfines, in rat stroke. Prominent neuronal upregulation of αEnsa was identified in 3 patterns within the ischemic gradient: (1) neurons in GFAP-/HSF1+ cortex showed upregulation and near-complete nuclear translocation of αEnsa protein within hours of ischemic onset; (2) neurons in GFAP+/HSF1+ cortex showed upregulation in cytoplasm and nuclei that persisted for days; (3) neurons in GFAP+/HSF1- cortex showed delayed cytosolic-only upregulation that persisted for days...

Yeast cell death can occur during wine alcoholic fermentation. It is generally considered to result from ethanol stress that impacts membrane integrity. This cell death mainly occurs when grape musts processing reduces lipid availability, resulting in weaker membrane resistance to ethanol. However the mechanisms underlying cell death in these conditions remain unclear. We examined cell death occurrence considering yeast cells ability to elicit an appropriate response to a given nutrient limitation and thus survive starvation...

The concept of being at risk for psychosis has been introduced both for adults and children and adolescents, but fewer studies have been conducted in the latter population. The aim of this study is to systematically review the articles associated with clinical description, interventions, outcome and other areas in children and adolescents at risk for psychosis. We searched in MEDLINE/PubMed and PsycINFO databases for articles published up to 30/06/16. Reviewed articles were prospective studies; written in English; original articles with Clinical High Risk (CHR) for psychosis samples; and mean age of samples younger than 18 years...

This study was conducted to evaluate the effect of enzyme-treated soy protein (ETSP) supplementation in the low-protein diet on growth performance, digestive and absorptive capacities, and related signaling molecules' gene expressions in juvenile Jian carp. The results showed that percent weight gain (PWG), specific growth rate (SGR), and feed intake (FI) were decreased by reducing dietary protein from 34 to 32% (P < 0.05). Supplying low-protein diet with optimal ETSP increased previously mentioned indices of juvenile Jian carp (P < 0...

The aminoacylation status of the cellular tRNA pool regulates both general amino acid control (GAAC) and target of rapamycin (TOR) stress response pathways in yeast. Consequently, fidelity of translation at the level of aminoacyl-tRNA synthesis plays a central role in determining accuracy and sensitivity of stress responses. To investigate effects of translational quality control (QC) on cell physiology under stress conditions, phenotypic microarray analyses were used to identify changes in QC deficient cells...

The killed bivalent (O1 and O139) whole cell oral cholera vaccine (OCV) (Shanchol™) was first licensed in India in 2009 and World Health Organization pre-qualified in 2011. We assessed the safety and immunogenicity of this OCV in the Philippines. This was a phase IV, single-arm, descriptive, open-label study. We recruited 336 participants from two centers: 112 participants in each age group (1-4, 5-14 and ≥15 years). Participants received two OCV doses 14 days apart. Safety was monitored throughout the trial...

In the environment and during infection, the human intestinal pathogen Vibrio cholerae must overcome noxious compounds that damage the bacterial outer membrane. The El Tor and classical biotypes of O1 V. cholerae show striking differences in their resistance to membrane disrupting cationic antimicrobial peptides (CAMPs), such as polymyxins. The classical biotype is susceptible to CAMPs, but current pandemic El Tor biotype isolates gain CAMP resistance by altering the net charge of their cell surface through glycine modification of lipid A...

Plant defense to microbial pathogens is often accompanied by significant growth inhibition. How plants merge immune system function with normal growth and development is still poorly understood. Here, we investigated the role of target of rapamycin (TOR), an evolutionary conserved serine/threonine kinase, in the plant defense response. We used rice as a model system and applied a combination of chemical, genetic, genomic and cell-based analyses. We demonstrate that ectopic expression of TOR and Raptor (regulatory-associated protein of mTOR), a protein previously demonstrated to interact with TOR in Arabidopsis, positively regulates growth and development in rice...

Adenosine (ADO) has been characterized as an endogenous anticonvulsant and alternative therapeutic drug, but its mechanism is not entirely clear. This study aimed to examine the relationship of ADO with the mammalian target of rapamycin (mTOR) in a Wistar rat model of pentylenetetrazole (PTZ)-induced acute status epilepticus. ADO (200 mg/kg) was administered intraperitoneally 30 min before PTZ (55-65 mg/kg) treatment, and Western blot assays and immunohistochemistry were performed 3 h after the onset of acute status epilepticus to detect phospho-TOR and the downstream target of mTOR, phospho-S6...
