The phytochemical investigation of the whole plant extracts of Herniaria glabra L. (Caryophyllaceae) led to the identification and isolation of four known flavonoids, one known and three undescribed maltol derivatives, and benzyl β-gentiobioside. The structures were established by extensive 1D and 2D NMR spectroscopic analyses, as well as HRESIMS data. For the first time in Herniaria genus, as well as in Caryophylaceae family the presence of apiorutin {quercetin 3-O-[(D-apio-β-d-furanosyl-(1 → 2)-O-[-α-l-rhamnopyranosyl-(1 → 6)]-β-d-glucopyranoside]} and licoagroside B {maltol 3-O-[6-O-(3-hydroxy-3-methylglutaroyl)]-β-d-glucopyranoside} were revealed...

Non-Structural Protein 1 (NS1) is a multifunctional protein involved in preventing host-interferon response in Influenza A Virus (IAV). Previous studies have indicated that NS1 also stimulates the translation of viral mRNA by binding to conserved sequences in the viral 5'-UTR. Additionally, NS1 binds to Poly (A) Binding Protein (PABP1) and eukaryotic Initiation Factor 4G (eIF4G). The interaction of NS1 with the viral 5'-UTR, PABP1, and eIF4G has been suggested to specifically enhance the translation of viral mRNAs...

Sindbis virus (SINV) is a mosquito borne virus maintained in nature in a mosquito-bird cycle, with human outbreaks known to occur in Northern Europe and parts of Africa. We analyzed five SINV strains isolated in Kenya from five different mosquito species and geographic locations between 2007 and 2013. Phylogenetic relationships and evolutionary inferences were performed using maximum likelihood and Bayesian phylogenetic inference approaches. Selection analyses were carried out based on the virus envelope glycoproteins (E1, E2) and non-structural protein (nsP4) genes...

Members of the plant-specific WOX (WUSCHEL-related homeobox) transcription factor family have been reported to play important roles in peptide signaling that regulates stem cell maintenance and cell fate specification in various developmental processes. Even though remarkable advances have been made in studying WOX genes in Arabidopsis , little is known about this family in Solanaceae species. A total of 45 WOX members from five Solanaceae species were identified, including eight members from Solanum tuberosum , eight from Nicotiana tomentosiformis , 10 from Solanum lycopersicum , 10 from Nicotiana sylvestris and nine from Nicotiana tabacum ...

Type 2 diabetes mellitus (T2D) is a heterogeneous disease, with certain cases presenting an autosomal dominant type. The rare coding variants of disease‑causing genes in T2D remain mostly unclear. The present study aimed to identify the disease‑causing gene conducting whole exome sequencing in a Thai T2D family with an autosomal dominant transmission of T2D with no evidence of mutations in known maturity‑onset diabetes of the young (MODY) genes. Candidate variants were selected according to certain criteria of mutation prediction programs, followed by segregation analysis with diabetes in the family...

Heat stress at the pollen mother cell (PMC) meiotic stage leads to pollen sterility in rice, in which the reactive oxygen species (ROS) and sugar homeostasis are always adversely affected. This damage is reversed by abscisic acid (ABA), but the mechanisms underlying the interactions among the ABA, sugar metabolism, ROS and heat shock proteins (HSPs) in rice spikelets under heat stress are unclear. Two rice genotypes, Zhefu802 (a recurrent parent) and fgl (its near-isogenic line) were subjected to heat stress of 40°C after pre-foliage sprayed with ABA and its biosynthetic inhibitor fluridone at the meiotic stage of PMC...

LAMA2-related muscular dystrophy (LAMA2 MD) is the most common and fatal form of early-onset congenital muscular dystrophies. Due to the large size of the laminin α2 cDNA and heterotrimeric structure of the protein, it is challenging to develop a gene-replacement therapy. Our group has developed a novel adeno-associated viral (AAV) vector carrying the mini-agrin, which is a non-homologous functional substitute for the mutated laminin α2. A significant therapeutic effect in skeletal muscle was observed in our previous study using AAV serotype 1 (AAV1)...

Interferon (IFN)-sensitive and replication-incompetent influenza viruses are likely to be the alternatives to inactivated and attenuated virus vaccines. Some IFN-sensitive influenza vaccine candidates with modified non-structural protein 1 (NS1) are highly attenuated in IFN-competent hosts but induce robust antiviral immune responses. However, little research has been done on the manufacturability of these IFN-sensitive vaccine viruses. Here, RIG-I-knockout 293T cells were used to package the IFN-sensitive influenza A/WSN/33 (H1N1) virus expressing the mutant NS1 R38A/K41A...

Afatinib, used for the first-line treatment of non-small-cell lung carcinoma (NSCLC) patients with distinct epidermal growth factor receptor (EGFR) mutations, inactivates EGFR by mimicking ATP structure and forming a covalent adduct with EGFR. We developed a method to unravel potential targets of afatinib in NSCLC cells through immunoprecipitation of afatinib-labeling proteins with anti-afatinib antiserum and mass spectrometry analysis. Ribonucleotide reductase (RNR) is one of target proteins of afatinib revealed by this method...

β-1,2-Glucan is a polysaccharide produced mainly by some Gram-negative bacteria as a symbiosis and infectious factor. We recently identified endo-β-1,2-glucanase from Chitinophaga pinensis ( CpSGL) as an enzyme comprising a new family. Here, we report the characteristics and crystal structure of a CpSGL homolog from Parabacteroides distasonis, an intestinal bacterium (BDI_3064 protein), which exhibits distinctive properties of known β-1,2-glucan-degrading enzymes. BDI_3064 hydrolyzed linear β-1,2-glucan and β-1,2-glucooligosaccharides with degrees of polymerization (DP) of 4 or more to produce sophorose specifically, but did not hydrolyze cyclic β-1,2-glucan...

Alzheimer's disease (AD) is a neurodegenerative disorder which has a higher prevalence and incidence in people older than 60 years. The need for improved AD therapies is unmet as the current therapies are symptomatic with modest efficacy. The 5-HT4 receptor (5-HT4R) partial agonists offer both symptomatic and disease modifying treatment as they shift amyloid precursor protein (APP) processing from amyloidogenic to non-amyloidogenic pathway by activating α-secretase enzyme. In addition, they also offer symptomatic treatment by increasing neurotransmitter acetylcholine levels in the brain...

The thalamic reticular nucleus (TRN), a shell-like structure comprised of GABAergic neurons, gates signal transmission between thalamus and cortex. While TRN is innervated by axon collaterals of thalamocortical and corticothalamic neurons, other ascending projections modulate activity during different behavioral states such as attention, arousal, and sleep-wake cycles. One of the largest arise from cholinergic neurons of the basal forebrain and brainstem. Despite its integral role, little is known about how or when cholinergic innervation and synapse formation occurs...

Symptoms of disseminated intravascular coagulation (DIC) include thromboembolism, acute attrition bleeding and multiple organ failure. Genistein isolated from leguminous plants has been shown to be effective in oxidation resistance and tumor inhibition. The present study was designed to evaluate the therapeutic effects of genistein in DIC and preliminarily discuss the mechanisms regarding the anti-inflammatory and anticoagulant effect of genistein. Swiss mice were randomly divided into the following groups-(1) lipopolysaccharide (LPS), (2) genistein, (3) dimethyl sulfoxide (DMSO, the non-major solvent component of genistein), (4) DMSO + LPS, (5) saline control group, and (6) heparin control group...

Aquaporins are integral proteins that facilitate the transmembrane transport of water and small solutes. In addition to enabling water flux, mammalian Aquaporin-1 (AQP1) channels activated by cyclic GMP can carry non-selective monovalent cation currents, selectively blocked by arylsulfonamide compounds AqB007 (IC50 170 μM) and AqB011 (IC50 14 μM). In silico models suggested that ligand docking might involve the cytoplasmic loop D (between AQP1 transmembrane domains 4 and 5), but the predicted site of interaction remained to be tested...

Zika virus (ZIKV) recently emerged as a global threat subsequent to its global spread because it induces microencephaly and other brain damages in infants born to infected mothers. Epidemiological monitoring of infection has been hampered by the absence of reliable serological tests capable to distinguish between ZIKV and other Flavivirus infections, in particular Dengue virus (DENV). As both viruses are transmitted by the same mosquito-species, their distributions largely overlap and reliable serological distinction between the viruses is essential...

Protein molecular conductance has attracted attention from researchers for the possibility of constructing innovative flexible biocompatible nanoscale electronic devices and smart hybrid materials. Due to protein complexity, most evaluations of protein conductivity are based on the simple estimation of protein's molecular orbital energy levels and spatial distributions without analysing its protein interaction with electrodes and the calculation of the rates of electron transfer (ET). In the present work, we included in our density functional theory (DFT) analysis an approach based on the non-equilibrium Green's function (NEGF) allowing for calculation from the first principles the molecular interaction with electrodes and thus the role of electrode materials, Fermi level, the thermal distribution of electronic energy levels, and the coupling efficiency between the molecule and the electrodes...

Influenza A virus (IAV) infection perturbs metabolic pathways such as autophagy, a stress-induced catabolic pathway that crosstalks with cellular inflammatory responses. However, the impact of autophagy perturbation on IAV gene expression or host cell responses remains disputed. Discrepant results may be a reflection of in vivo studies using cell-specific autophagy-related (Atg) gene-deficient mouse strains, which do not delineate modification of developmental programmes from more proximal effects on inflammatory response...

IRE1α (Inositol Requiring kinase Enzyme 1 alpha), a transmembrane protein localized to the endoplasmic reticulum (ER) is a master regulator of the unfolded protein response (UPR) pathway. The fate determining steps during ER stress-induced apoptosis are greatly attributed to IRE1α's endoribonuclease and kinase activities. Apart from its role as a chief executioner in ER stress, recent studies have shown that upon activation in the presence or absence of ER stress, IRE1α executes multiple cellular processes such as differentiation, immune response, progression and repression of the cell cycle...
