Oncogenic Role of eIF-5A2 in the Development of Ovarian Cancer (2004)

Abstract Amplification of 3q26 is one of the most frequent chromosomal alterations in many solid tumors, including ovarian, lung, esophageal, prostate, breast, and nasopharyngeal cancers. A candidate oncogene to eukaryotic initiation factor 5A2 (eIF-5A2), a member of eukaryotic initiation factor 5A subfamily, has been isolated from a frequently amplified region at 3q26.2. In this work, the tumorigenic ability of eIF-5A2 was demonstrated by anchorage-independent growth in soft agar and tumor formation in nude mice. Furthermore, antisense DNA against eIF-5A2 could inhibit cell growth in ovarian cancer cell line UACC-1598 with amplification of eIF-5A2 in form of double minutes. Cell growth rate in UACC-1598 was also inhibited when the expression level of EIF-5A2 was decreased by the reduction of the copy number of double minutes. The correlation of EIF-5A2 overexpression and clinical features of ovarian cancer was investigated using tissue microarray, and the result showed that eIF-5A2 overexpression was significantly associated with the advanced stage of ovarian cancer. These findings suggest that eIF-5A2 plays important roles in ovarian pathogenesis.
The human olfactory receptor gene family (2004)

Humans perceive an immense variety of chemicals as having distinct odors. Odor perception initiates in the nose, where odorants are detected by a large family of olfactory receptors (ORs). ORs have diverse protein sequences but can be assigned to subfamilies on the basis of sequence relationships. Members of the same subfamily have related sequences and are likely to recognize structurally related odorants. To gain insight into the mechanisms underlying odor perception, we analyzed the human OR gene family. By searching the human genome database, we identified 339 intact OR genes and 297 OR pseudogenes. Determination of their genomic locations showed that OR genes are unevenly distributed among 51 different loci on 21 human chromosomes. Sequence comparisons showed that the human OR family is composed of 172 subfamilies. Types of odorant structures that may be recognized by some subfamilies were predicted by identifying subfamilies that contain ORs with known odor ligands or human homologs of such ORs. Analysis of the chromosomal locations of members of each OR subfamily revealed that most subfamilies are encoded by a single chromosomal locus. Moreover, many loci encode only one or a few subfamilies, suggesting that different parts of the genome may, to some extent, be involved in the detection of different types of odorant structural motifs.
A One-Pot Synthesis of Functionalised 3-pyrolin-2-ones by a four-component reaction between Triphenylphosphine, Primary Amines, Dimethyl Acetylenedicarboxylate and Ethyl Chlorooxoacetate (2007)

Reaction between triphenylphosphine, dimethy acetylenedicarboxylate and amines produces phosphorus ylids which undergo a smooth reaction with ethyl chlorooxoacetate and triethylamine to produce dimethyl N-aryl-(or alkyl)-4-ethoxy-5-oxo-2,5-dihydro-1 H-pyrole-2,3-dicarboxylates in high yields.
Movement of Bax from the Cytosol to Mitochondria during Apoptosis (1997)

Bax, a member of the Bcl-2 protein family, accelerates apoptosis by an unknown mechanism. Bax has been recently reported to be an integral membrane protein associated with organelles or bound to organelles by Bcl-2 or a soluble protein found in the cytosol. To explore Bcl-2 family member localization in living cells, the green fluorescent protein (GFP) was fused to the NH2 termini of Bax, Bcl-2, and Bcl-XL. Confocal microscopy performed on living Cos-7 kidney epithelial cells and L929 fibroblasts revealed that GFP-Bcl-2 and GFP-Bcl-XL had a punctate distribution and colocalized with a mitochondrial marker, whereas GFP-Bax was found diffusely throughout the cytosol. Photobleaching analysis confirmed that GFP-Bax is a soluble protein, in contrast to organelle-bound GFP-Bcl-2. The diffuse localization of GFP-Bax did not change with coexpression of high levels of Bcl-2 or Bcl-XL. However, upon induction of apoptosis, GFP-Bax moved intracellularly to a punctate distribution that partially colocalized with mitochondria. Once initiated, this Bax movement was complete within 30 min, before cellular shrinkage or nuclear condensation. Removal of a COOH-terminal hydrophobic domain from GFP-Bax inhibited redistribution during apoptosis and inhibited the death-promoting activity of both Bax and GFP-Bax. These results demonstrate that in cells undergoing apoptosis, an early, dramatic change occurs in the intracellular localization of Bax, and this redistribution of soluble Bax to organelles appears important for Bax to promote cell death.
Liver-Specific Expression of Transcriptionally Active SREBP-1c Is Associated with Fatty Liver and Increased Visceral Fat Mass (2012)

The pathogenesis of fatty liver is not understood in detail, but lipid overflow as well as de novo lipogenesis (DNL) seem to be the key points of hepatocyte accumulation of lipids. One key transcription factor in DNL is sterol regulatory element-binding protein (SREBP)-1c. We generated mice with liver-specific over-expression of mature human SREBP-1c under control of the albumin promoter and a liver-specific enhancer (alb-SREBP-1c) to analyze systemic perturbations caused by this distinct alteration. SREBP-1c targets specific genes and causes key enzymes in DNL and lipid metabolism to be up-regulated. The alb-SREBP-1c mice developed hepatic lipid accumulation featuring a fatty liver by the age of 24 weeks under normocaloric nutrition. On a molecular level, clinical parameters and lipid-profiles varied according to the fatty liver phenotype. The desaturation index was increased compared to wild type mice. In liver, fatty acids (FA) were increased by 50% (p<0.01) and lipid composition was shifted to mono unsaturated FA, whereas lipid profile in adipose tissue or serum was not altered. Serum analyses revealed a ∼2-fold (p<0.01) increase in triglycerides and free fatty acids, and a ∼3-fold (p<0.01) increase in insulin levels, indicating insulin resistance; however, no significant cytokine profile alterations have been determined. Interestingly and unexpectedly, mice also developed adipositas with considerably increased visceral adipose tissue, although calorie intake was not different compared to control mice. In conclusion, the alb-SREBP-1c mouse model allowed the elucidation of the systemic impact of SREBP-1c as a central regulator of lipid metabolism in vivo and also demonstrated that the liver is a more active player in metabolic diseases such as visceral obesity and insulin resistance.
The receptor for advanced glycation end-products has a central role in mediating the effects of advanced glycation end-products on the development of vascular disease in diabetes mellitus (1996)

Proteins or lipids exposed to aldose sugars undergo initial and ultimately irreversible modification resulting in the formation of so-called advanced glycation end-products (AGEs). AGEs are postulated to be especially important in the setting of diabetes mellitus due to hyperglycaemia characteristic of this disorder. Our work has demonstrated that one of the principal means by which AGEs interact with the vascular wall is by interaction with their cellular receptor, the receptor for advanced glycation end-products (RAGE), which is present on the surface of endothelial cells, smooth muscle cells, mesangial cells, mononuclear phagocytes and certain neurons. AGEs interact with RAGE, resulting in the induction of monocyte chemotaxis as well as oxidant stress. One of the consequences of AGE-RAGE-induced cellular oxidant stress is the enhanced expression of vascular cell adhesion molecule-1 on the endothelial surface, a critical consequence of which is the attraction of mononuclear phagocytes into the vessel wall. In both cases, the pro-inflammatory effects of AGEs may be inhibited in the presence of RAGE blockade, using either anti-RAGE F(ab')2 or soluble RAGE, the extracellular domain of the molecule. These data suggest that inhibition of RAGE may interfere with monocyte chemotaxis and attraction into the vessel wall where AGEs deposit/form, suggesting the potential of this intervention to interfere with a critical step in the development of vascular disease, especially in patients with diabetes.
The usefulness of dietary medium-chain triglycerides in body weight control: fact or fancy? (1996)

Compared to long-chain triglycerides (LCT), medium-chain triglycerides (MCT) display some specific physico-chemical, and biological characteristics. Thus, MCT are currently used in clinical nutrition as energy-yielding substrates, and have been advocated for three decades as a useful mean for body weight reduction. This review encompasses most aspects of MCT metabolism arguing this slimming hypothesis pro and con. Findings in support of the opinion (lower energy density, control of satiety, rapid intrahepatic delivery and oxidation rates, poor adipose tissue incorporation) may be invalidated by counteracting data (stimulation of insulin secretion and of anabolic-related processes, increased de novo fatty acid synthesis, induced hypertriglyceridemia). The balance between these two opposing influences depends on the composition (energy intake, nature of ingredients, MCT/LCT ratio, octanoate/decanoate ratio) and duration of the regimen. Due to the high energy level (around 50%) of MCT necessary to achieve body weight loss, long-term compliance to such slimming regimens is unlikely in human nutrition.
Introduction of specific point mutations into RNA polymerase II by gene targeting in mouse embryonic stem cells: evidence for a DNA mismatch repair mechanism. (1990)

We have introduced two specific point mutations, located 20 base pairs apart, into the endogenous murine gene that encodes the largest subunit of RNA polymerase II (RPII215). The first mutation conferred resistance to the mushroom toxin alpha-amanitin (amar), and the second mutation generated a restriction fragment length polymorphism without altering the protein sequence. Targeted amar clones were generated at a frequency of 1 in 30 totipotent embryonic stem cells that expressed stably integrated DNA vectors after electroporation. Thirty to 40% of these clones had acquired both mutations, whereas, surprisingly, the remaining clones had acquired the specific amar point mutation but lacked the restriction fragment length polymorphism. We suggest that the latter clones were generated by independent DNA mismatch repair rather than by double crossover or gene conversion. These results demonstrate that it is possible to introduce specific point mutations into an endogenous gene in embryonic stem cells. Thus it should be possible to introduce single base substitutions into other cellular genes, including nonselectable genes, by optimizing the efficiency of gene transfer and/or the sensitivity of screening for targeted clones.
Beyond Stressed Self: Evidence for NKG2D Ligand Expression on Healthy Cells (2009)

The activity of cytotoxic lymphocytes is regulated by the opposing function of stimulatory and inhibitory cell surface receptors. According to the now classical model of Natural Killer (NK) cell activity, the ligands for inhibitory receptors are constitutively expressed on healthy cells but can be lost on infection and on malignant cells. Loss of inhibitory checks will then allow activating signals to predominate, forming the basis of 'missing self recognition'. Natural Killer Group 2D (NKG2D) is an important member of the cohort of activating receptors expressed on Natural Killer (NK) cells and subsets of T cells. Ligands for the NKG2D receptor comprise a diverse array of self-proteins structurally related to MHC class I molecules. Expression of NKG2D ligands can be induced in cells during infection with pathogens, tumourigenesis, and by stimuli such as DNA damage, oxidative stress, and heat shock. Consequently NKG2D has been widely described as participating in 'stressed self' or 'damaged self' recognition. However, a body of evidence has recently emerged to suggest that this intuitive model of NKG2D function may be an oversimplification. NKG2D ligand expression has now widely been reported on cells that could not be described as stressed or damaged. For example activated T cells can express NKG2D ligands, and constitutive expression of NKG2D ligands has been reported on normal myelomonocytic cells, dendritic cells, and epithelial cells of the gut mucosa. In this article we will review the literature suggesting that NKG2D may function to recognise non-stressed cells and discuss the role NKG2D ligands could be playing in apparently healthy cells.

Acute myeloid leukemia with mutated nucleophosmin (NPM1): is it a distinct entity? (2010)

After the discovery of NPM1-mutated acute myeloid leukemia (AML) in 2005 and its subsequent inclusion as a provisional entity in the 2008 World Health Organization classification of myeloid neoplasms, several controversial issues remained to be clarified. It was unclear whether the NPM1 mutation was a primary genetic lesion and whether additional chromosomal aberrations and multilineage dysplasia had any impact on the biologic and prognostic features of NPM1-mutated AML. Moreover, it was uncertain how to classify AML patients who were double-mutated for NPM1 and CEBPA. Recent studies have shown that: (1) the NPM1 mutant perturbs hemopoiesis in experimental models; (2) leukemic stem cells from NPM1-mutated AML patients carry the mutation; and (3) the NPM1 mutation is usually mutually exclusive of biallelic CEPBA mutations. Moreover, the biologic and clinical features of NPM1-mutated AML do not seem to be significantly influenced by concomitant chromosomal aberrations or multilineage dysplasia. Altogether, these pieces of evidence point to NPM1-mutated AML as a founder genetic event that defines a distinct leukemia entity accounting for approximately one-third of all AML.
Dual mTORC1/2 inhibition induces anti-proliferative effect in NF1-associated plexiform neurofibroma and malignant peripheral nerve sheath tumor cells (2016)

Approximately 30-50% of individuals with Neurofibromatosis type 1 develop benign peripheral nerve sheath tumors, called plexiform neurofibromas (PNFs). PNFs can undergo malignant transformation to highly metastatic malignant peripheral nerve sheath tumors (MPNSTs) in 5-10% of NF1 patients, with poor prognosis. No effective systemic therapy is currently available for unresectable tumors. In tumors, the NF1 gene deficiency leads to Ras hyperactivation causing the subsequent activation of the AKT/mTOR and Raf/MEK/ERK pathways and inducing multiple cellular responses including cell proliferation. In this study, three NF1-null MPNST-derived cell lines (90-8, 88-14 and 96-2), STS26T sporadic MPNST cell line and PNF-derived primary Schwann cells were used to test responses to AZD8055, an ATP-competitive "active-site" mTOR inhibitor. In contrast to rapamycin treatment which only partially affected mTORC1 signaling, AZD8055 induced a strong inhibition of mTORC1 and mTORC2 signaling in MPNST-derived cell lines and PNF-derived Schwann cells. AZD8055 induced full blockade of mTORC1 leading to an efficient decrease of global protein synthesis. A higher cytotoxic effect was observed with AZD8055 compared to rapamycin in the NF1-null MPNST-derived cell lines with IC50 ranging from 70 to 140 nM and antiproliferative effect was confirmed in PNF-derived Schwann cells. Cell migration was impaired by AZD8055 treatment and cell cycle analysis showed a G0/G1 arrest. Combined effects of AZD8055 and PD0325901 MEK inhibitor as well as BRD4 (BromoDomain-containing protein 4) inhibitors showed a synergistic antiproliferative effect. These data suggest that NF1-associated peripheral nerve sheath tumors are an ideal target for AZD8055 as a single molecule or in combined therapies.
Recombinant Vaccinia Viruses Protect Against Clostridium perfringens α-Toxin (1999)

Recombinant vaccinia viruses that expressed the nontoxic C-domain of Clostridium perfringens alpha-toxin were constructed. The J2R (thymidine kinase [TK] gene) and B13R (serpin 2 [SPI-2] gene) loci were used as insertion sites for the clostridial DNA, and expression of the foreign protein was measured in each case. A double recombinant that encoded the alpha-toxin truncate at the B13R locus and the protective antigen of Bacillus anthracis at the J2R locus was also constructed. Although differences in expression of the alpha-toxin C-domain were recorded, all of the vaccinia recombinants protected mice against a lethal challenge with alpha-toxin demonstrating that a recombinant vaccinia virus can be used to provide protection against a toxin challenge that is known to be solely antibody mediated.
A mutation in the Bordetella bronchiseptica bvgS gene results in reduced virulence and increased resistance to starvation, and identifies a new class of Bvg‐regulated antigens (1997)

The Bordetella BvgAS signal-transduction system has traditionally been viewed as mediating a transition between two distinct phenotypic phases: the Bvg+ phase, characterized by the expression of adhesins and toxins, and the Bvg-phase, characterized by motility in Bordetella bronchiseptica and by the expression of vrg loci in Bordetella pertussis. In B. bronchiseptica, the Bvg+ phase is necessary and sufficient for respiratory tract colonization whereas the Bvg phase is required for growth under nutrient-limiting conditions. This report describes the characterization of a mutant that is locked in a Bvg-intermediate (Bvg[i]) phase. The mutation conferring this phenotype, designated bvgS-I1, results in a threonine-to-methionine substitution near the primary site of phosphorylation in BvgS. Compared to its Bvg+-phase-locked parent, the Bvg(i) mutant displays increased resistance to nutrient limitation and reduced virulence. Molecular analyses indicate that the mutant has lost the ability to express a subset of Bvg+-phase factors and has gained the ability to express factors unique to the Bvg(i) phase. Although identified by mutation, this work indicates that the Bvg(i) phase is expressed by wild-type B. bronchiseptica in response to certain (semi-modulating) environmental conditions. The identification of Bvg(i)-specific antigens suggests the existence of a new class of Bvg-regulated genes. We hypothesize that BvgAS is capable of mediating the expression of a spectrum of phenotypic phases in response to the various environments encountered as Bordetella travels within and between mammalian hosts.
Self-dissolving microneedles for the percutaneous absorption of EPO in mice (2006)

Erythropoietin (EPO) loaded microneedles were prepared using thread-forming polymer as a base for the percutaneous administration of EPO. The used polymers were dextrin, chondroitin sulfate and albumin. Under room temperature, EPO solution was added to high concentration of polymer solution and microneedles were prepared by forming thread with polypropylene tips. The mean weight of microneedle was 0.59 +/- 0.01 mg and length and basal diameter were 3.24 +/- 0.16 and 0.55 +/- 0.03 mm, respectively. Four microneedles were percutaneously (pc) administered to mice at the EPO dose levels of 100 IU/kg. After administration, blood samples were collected for 24 h and serum EPO levels were measured. Dextrin EPO microneedles were administered both pc and subcutaneously (sc) to mice. Serum EPO levels vs. time profiles showed Cmax of 138.6 +/- 16.1 and 146.5 +/- 8.0 mIU/ml, respectively. Tmax were 7.5 h. The values of bioavailability (BA) of EPO were 82.1 and 99.4%, respectively. By decreasing the dose from 100 to 50 and 25 IU/kg, dose-dependent serum EPO levels vs. time profiles were not clearly obtained. When chondroitin sulfate and albumin were used as the microneedle base, the serum EPO levels vs. time profiles showed almost the same pattern. Cmax of chondroitin sulfate and albumin microneedles were 96.3 +/- 8.8 and 132.2 +/- 18.9 mIU/ml, respectively. AUCs were 835.1 and 1098.7 mIU h/ml. Tmax were 8 and 6.8 h. These results suggest the usefulness of microneedles for the percutaneous administration of EPO.
Non-aqueous spray solvents and solubility effects in desorption electrospray ionization (2010)

The use of non-aqueous solvents in desorption electrospray ionization mass spectrometry (DESI-MS) is explored by analyzing a set of 43 compounds using binary mixtures of chloroform, tetrahydrofuran, and acetonitrile as the spray solvent. Comparisons of data obtained from chloroform/tetrahydrofuran (1:1) and chloroform/acetonitrile (1:1) spray solvents with the standard aqueous-based spray solvent (methanol/water, 1:1) shows that the non-aqueous systems have practical value for DESI, especially in the analysis of hydrophobic compounds. Non-aqueous spray solvents were used to ionize thermometer molecules (benzyl pyridinium salts) and showed lower internal energies (softer DESI ionization compared with methanol/water, 1:1), a result that has parallels in known solvent effects in electrospray ionization and is explained by solvent effects on surface tension. Consideration of octanol/water partition coefficients (K(ow)) of the 43 analytes in the light of their DESI results reveals the importance of the solubility of analyte in the spray solvent in producing high quality mass spectra. This finding provides additional support for the droplet pick-up description of the DESI mechanism, which is based on analyte dissolution in the spray solvent, followed by splashing of subsequently arriving droplets in the liquid film to form microdroplets of dissolved analyte. DESI solvent optimization can be improved by the use of K(ow) of the analyte as an indication of the polarity of the most appropriate solvent system.
