Polyamines (PAs) are implicated in developmental processes and stress responses of plants. Polyamine oxidases (PAOs), flavin adenine dinucleotide-dependent enzymes that function in PA catabolism, play a critical role. Even though PAO gene families of Arabidopsis and rice have been intensely characterized and their expression in response to developmental and environmental changes has been investigated, little is known about PAOs in tomato (Solanum lycopersicum). We found seven PAO genes in S. lycopersicum and named them SlPAO1∼7...

Christina E Bailey, Alexander A Parikh
Angiogenesis plays a critical role in the growth, progression, and metastasis of numerous solid tumor types, and thus, antiangiogenic agents have been studied for many years as potential therapeutic agents. Many different antiangiogenic agents, including monoclonal antibodies and multi-targeted tyrosine kinase inhibitors (TKIs), have been approved for various oncology indications, and promising clinical activity has been demonstrated. However, some of these agents have also been associated with serious safety concerns...

BACKGROUND: Alterations in peripheral sex hormones may play an important role in sex differences in terms of stress responses and mood disorders. It is not yet known whether and how stress-related brain systems and brain sex steroid levels fluctuate in relation to changes in peripheral sex hormone levels, or whether the different sexes show different patterns. We aimed to investigate systematically, in male and female rats, the effect of decreased circulating sex hormone levels following gonadectomy on acute and chronic stress responses, manifested as changes in plasma and hypothalamic sex steroids and hypothalamic stress-related molecules...

Ferritin is a ubiquitous iron storage protein that plays an important role in host defence against pathogen infections. In the present study, native ferritin was isolated from the hemolymph of Bombyx mori using native-polyacrylamide gel electrophoresis (native-PAGE) and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The results revealed that ferritin consisted of two subunits, designated as BmFerHCH and BmFerLCH. Previously integrated previous transcriptome and iTRAQ data showed that the two subunits were down-regulated in resistant silkworm strain BC9 and there was no obvious change in the expression levels of the subunits in susceptible silkworm strain P50 after BmNPV infection...

Phosphoinositide 3-kinase (PI3K) plays an important role in platelet function and contributes to platelet hyperreactivity induced by elevated levels of circulating peptide hormones, including thrombopoietin (TPO). Previous work established an important role for the PI3K isoform; p110β in platelet function, however the role of p110α is still largely unexplored. Here we sought to investigate the role of p110α in TPO-mediated hyperactivity by using a conditional p110α knockout (KO) murine model in conjunction with platelet functional assays...

Health literacy plays a crucial role in chronic disease management. To comprehensively manage chronic conditions on a daily basis, individuals must be able to assess, understand, evaluate and use health information. Several key publications emphasise that health literacy is not merely a matter of individual skills, but that it is highly dependent on the accessibility of healthcare systems, the communication skills of healthcare professionals, and the level of complexity of health information. However, the literature indicates that health literacy is mainly framed and measured as an individual attribute in research...

Serum 25-hydroxyvitamin D /25OHD/ levels in humans are determined primarily by environmental factors such as UV-B radiation and diet, including vitamin D intake. Although some genetic determinants of 25OHD levels have been shown, the magnitude of this association has not yet been clarified. The present study evaluates the genetic contribution to total- /t-25OHD/ and free-25OHD /f-25OHD/ in a representative sample of the Hungarian population (n = 462). The study was performed at the end of winter to minimize the effect of sunlight, which is a major determinant of serum vitamin D levels...

Fisetin, a natural flavonoid, has neuroprotection properties in many brain injury models. However, its role in traumatic brain injury (TBI) has not been fully explained. In the present study, we aimed to explore the neuroprotective effects of fisetin in a mouse model of TBI. We found that fisetin improved neurological function, reduced cerebral edema, attenuated brain lesion and ameliorated blood-brain barrier (BBB) disruption after TBI. Moreover, the up-regulation of malondialdehyde (MDA) and the activity of glutathione peroxidase (GPx) were reversed by fisetin treatment...

The Ginkgo biloba L. chichi is a unique organ. To explore the molecular mechanisms underlying the ontogenesis of G. biloba chichi, we used RNA-seq to analyse the transcriptome profile of rooted chichi at two developmental stages (ch1 and ch2) and nearby tissues (ck), and each sample had three biological replicates. A total of 57.74 Gb of clean bases were generated in nine cDNA libraries. These bases were de novo assembled into 68,277 unigenes with average length of 844 bp, and 51.47% of the unigenes had a match in at least one public database...

Cowpea is an important horticultural crop in tropical and subtropical areas of Asia, Africa, and Latin America, as well as parts of southern Europe and Central and South America. Chilling injury is a common physiological hazard of cowpea in cold chain logistics which reduce the cowpea pod's nutritional quality and product value. However, the molecular mechanism involved in chilling injury remains unclear in cowpea pods. RNA-Seq and sRNA-Seq technologies were employed to decipher the miRNAs and mRNAs expression profiles and their regulatory networks in cowpea pods involved in chilling stress...

Fruit rot caused mainly by Colletotrichum gloeosporioides is a major cause of pre- and/or post-harvest diseases, which seriously constrains production, marketing, and export of fruits. To infect the host, this fungus evolves a specialized infection structure called the appressorium. Extensive past studies have characterized many appressorium-related genes in C. gloeosporioides, separately. However, a comprehensive understanding of the genes contributing to appressorium formation is far from complete. Here, global changes in gene expression were analyzed between appressoria and hyphae using RNA-Seq...

Cardiovascular disease (CVD) due to atherosclerosis is a disease of chronic inflammation at both the systemic and the tissue level. CD44 has previously been implicated in atherosclerosis in both humans and mice. This multi-faceted receptor plays a critical part in the inflammatory response during the onset of CVD, though little is known of CD44's role during the latter stages of the disease. This review focuses on the role of CD44-dependent HA-dependent effects on inflammatory cells in several key processes, from disease initiation throughout the progression of atherosclerosis...

Interleukin (IL)-11 plays an important role in the immune system. However, IL-11 has not yet been characterized in avian species, including chickens. This study is the first to clone and functionally characterize chicken IL-11 (chIL-11). Multiple alignments and phylogenetic tree comparisons of chIL-11 with IL-11 proteins from other species revealed high levels of conservation and a close relationship between chicken and Japanese quail IL-11. Our results demonstrate that chIL-11 was a functional ligand of IL-11RA and IL-6ST in chicken HD11 and OU2 cell lines, as well as activated and regulated JAK-STAT, NF-κB, PI3K/AKT, and MAPK signaling pathways in chicken cell lines...

Fusobacterium nucleatum (F. nucleatum) in the tumor microenvironment plays an important role in the development of colorectal cancer (CRC). The underlying mechanism of action, however, remains to be elucidated. We evaluated the relation of F. nucleatum amount to thymocyte selection-associated high-mobility group box (TOX) protein expression and CD4+ T cell density in 138 human colorectal tissues. TOX expression and CD4+ T cell density in F. nucleatum negative tissues were significantly higher compared to those in F...

Osteoarthritis (OA) is a prevalent joint disorder worldwide. Recent studies suggested that macrophages play an important role in the progression of OA. However, the detailed pathology related to macrophages is still ambiguous, especially those related to mechanotransduction. In this study, PCL/EUG composite scaffolds were first fabricated by electrospinning. The stiffness of as-fabricated scaffolds was controlled by adjusting the PCL-versus-EUG ratio. The mechanical properties, structural characterics and chemical composition of the scaffolds were investigated using various materials characterization techniques...

Iron-mediated generation of highly toxic Reactive Oxygen Species (ROS) plays a major role in the process leading to iron overload-related diseases. The long-term subcutaneous administration of Deferoxamine (DFO) is currently clinically-approved to improve patient symptoms and survival. However, non-specific toxicity and short circulation times of the drug in humans often leads to poor patient compliance. Herein, thioketal-based ROS-responsive polymeric nanogels containing DFO moieties (rNG-DFO) were designed to chelate iron and to degrade under oxidative stimuli into fragments <10 nm to enhance excretion of iron-bound chelates...

Aspirin is a novel chemopreventive agent against malignancy. However, outcomes of aspirin monotherapy of renal cell carcinoma (RCC) are inconsistent across studies. ABT-737, an BH3 mimetic inhibitor, is also a promising antitumor drug. Cancer cells including those from RCC, that have high levels of Mcl-1, are refractory to ABT-737-induced apoptosis. We here investigated how aspirin treatment modulates the ABT-737-induced apoptosis. Using the in vitro model of human 786-O cells, we showed that aspirin had sensitized cells to ABT-737 induced apoptosis...
