Inhibition of LPS-induced iNOS, COX-2 and cytokines expression by poncirin through the NF-kappaB inactivation in RAW 264.7 macrophage cells.[Pubmed: 18057724]Poncirin promotes osteoblast differentiation but inhibits adipocyte differentiation in mesenchymal stem cells.[Pubmed: 21550337]Eur J Pharmacol. 2011 Aug 16;664(1-3):54-9. Poncirin, flavanone glycoside, isolated from the fruit of Poncirus trifoliata, has anti-bacterial and anti-inflammatory activities. METHODS AND RESULTS:In this study, the effects of Poncirin on the differentiation of mesenchymal stem cells were investigated. The C3H10T1/2 mesenchymal stem cells and primary bone marrow mesenchymal stem cells were studied. In the C3H10T1/2 cells, Poncirin prevented adipocyte differentiation, as demonstrated by inhibition of cytoplasm lipid droplet accumulation and peroxisome proliferator-activating receptor-γ (PPAR-γ) and CCAAT-enhancer-binding protein-β (C/EBP-β) mRNA expression. By contrast, Poncirin enhanced the expression of the key osteogenic transcription factors, runt-related transcription factor 2 (Runx2) and transcriptional coactivator with PDZ-binding motif (TAZ). Poncirin also enhanced expression of the osteogenic marker genes including alkaline phosphatase (ALP) and osteocalcin (OC). Poncirin increased mineral nodule formation in primary bone marrow mesenchymal stem cells. CONCLUSIONS:These results suggest that Poncirin prevents adipogenesis and enhances osteoblast differentiation in mesenchymal stem cells.Biol Pharm Bull. 2007 Dec;30(12):2345-51. We previously reported that Poncirin, a flavanone glycoside isolated from the EtOAc extract of the dried immature fruits of Poncirus trifoliata, is an anti-inflammatory compound that inhibits PGE(2) and IL-6 production. METHODS AND RESULTS:The present work was undertaken to investigate the molecular actions of Poncirin in RAW 264.7 macrophage cell line. Poncirin reduced lipopolysaccharide (LPS)-induced protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) and the mRNA expressions of iNOS, COX-2, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in a concentration-dependent manner, as determined by Western blotting and RT-PCR, respectively. Furthermore, Poncirin inhibited the LPS-induced DNA binding activity of nuclear factor-kappaB (NF-kappaB). Moreover, this effect was accompanied by a parallel reduction in IkappaB-alpha degradation and phosphorylation that in by nuclear translocations of p50 and p65 NF-kappaB subunits.CONCLUSIONS: Taken together, our data indicate that anti-inflammatory properties of Poncirin might be the result from the inhibition iNOS, COX-2, TNF-alpha and IL-6 expression via the down-regulation of NF-kappaB binding activity.

Abstract

Background
We describe 22 new species in the genus Hyphantrophaga Townsend, 1892 (Diptera: Tachinidae) from Area de Conservacion Guanacaste (ACG) in north-western Costa Rica. All species were reared from an ongoing inventory of wild-caught caterpillars spanning a variety of families (Lepidoptera: Bombycidae, Crambidae, Depressariidae, Doidae, Erebidae, Euteliidae, Gelechiidae, Geometridae, Hedylidae, Hesperiidae, Immidae, Lasiocampidae, Limacodidae, Megalopygidae, Mimaloniidae, Noctuidae, Nolidae, Notodontidae, Nymphalidae, Papilionidae, Pieridae, Phiditiidae, Pterophoridae, Pyralidae, Riodinidae, Saturniidae, Sphingidae, Thyrididae, Tortricidae and Zygaenidae). We provide a morphological description of each species together with information on life history, molecular data and photographic documentation. In addition to the new species, we provide a redescription of the genus, as well as the redescription of three previously described species, which were also collected within ACG during this study: Hyphantrophaga angustata (van der Wulp), Hyphantrophaga myersi (Aldrich) and Hyphantrophaga virilis (Aldrich & Webber).

New information
The following 22 new species of Hyphantrophaga are described: Hyphantrophaga adrianguadamuzi Fleming & Wood sp. n., Hyphantrophaga albopilosa Fleming & Wood sp. n., Hyphantrophaga anacordobae Fleming & Wood sp. n., Hyphantrophaga calixtomoragai Fleming & Wood sp. n., Hyphantrophaga calva Fleming & Wood sp. n.., Hyphantrophaga ciriloumanai Fleming & Wood sp. n., Hyphantrophaga danausophaga Fleming & Wood sp. n., Hyphantrophaga diniamartinezae Fleming & Wood sp. n., Hyphantrophaga duniagarciae Fleming & Wood sp. n., Hyphantrophaga edwinapui Fleming & Wood sp. n., Hyphantrophaga eldaarayae Fleming & Wood sp. n., Hyphantrophaga eliethcantillanoe Fleming & Wood sp. n., Hyphantrophaga gilberthampiei Fleming & Wood sp. n., Hyphantrophaga guillermopereirai Fleming & Wood sp. n., Hyphantrophaga hazelcambroneroae Fleming & Wood sp. n., Hyphantrophaga luciariosae Fleming & Wood sp. n., Hyphantrophaga manuelriosi Fleming & Wood sp. n., Hyphantrophaga morphophaga Fleming & Wood sp. n., Hyphantrophaga nigricauda Fleming & Wood sp. n., Hyphantrophaga osvaldoespinozai Fleming & Wood sp. n., Hyphantrophaga pabloumanai Fleming & Wood sp. n. and Hyphantrophaga similis Fleming & Wood sp. n.

The following are proposed by Wood as new synonyms of Hyphantrophaga Townsend, 1892: Brachymasicera Townsend, 1911 syn. n., Ommasicera Townsend, 1911 syn. n., Ophirosturmia Townsend, 1911 syn. n., Patillalia Curran, 1934 syn. n. and Ypophaemyiops Townsend, 1935 syn. n.

The following nine new combinations are proposed as a result of the new synonymies: Hyphantrophaga adamsoni (Thompson, 1963), comb. n., Hyphantrophaga fasciata (Curran, 1934), comb. n., Hyphantrophaga glauca (Giglio-Tos, 1893), comb. n., Hyphantrophaga gowdeyi (Curran, 1926), comb. n., Hyphantrophaga myersi (Aldrich, 1933), comb. n., Hyphantrophaga nigripes (Townsend, 1928), comb. n., Hyphantrophaga optica (Schiner, 1868), comb. n., Hyphantrophaga polita (Townsend, 1911), comb. n., Hyphantrophaga subpolita (Townsend, 1912), comb. n.

Abstract

The Stagonospora nodorum StuA transcription factor gene SnStuA was identified by homology searching in the genome of the wheat pathogen Stagonospora nodorum. Gene expression analysis revealed that SnStuA transcript abundance increased throughout infection and in vitro growth to peak during sporulation. To investigate its role, the gene was deleted by homologous recombination. The growth of the resulting mutants was retarded on glucose compared to the wild-type growth, and the mutants also failed to sporulate. Glutamate as a sole carbon source restored the growth rate defect observed on glucose, although sporulation remained impaired. The SnstuA strains were essentially nonpathogenic, with only minor growth observed around the point of inoculation. The role of SnstuA was investigated using metabolomics, which revealed that this gene’s product played a key role in regulating central carbon metabolism, with glycolysis, the TCA cycle, and amino acid synthesis all affected in the mutants. SnStuA was also found to positively regulate the synthesis of the mycotoxin alternariol. Gene expression studies on the recently identified effectors in Stagonospora nodorum found that SnStuA was a positive regulator of SnTox3 but was not required for the expression of ToxA. This study has uncovered a multitude of novel regulatory targets of SnStuA and has highlighted the critical role of this gene product in the pathogenicity of Stagonospora nodorum.

Abstract

While multiple studies have reported the accelerated evolution of brain gene expression in the human lineage, the mechanisms underlying such changes are unknown. Here, we address this issue from a developmental perspective, by analyzing mRNA and microRNA (miRNA) expression in two brain regions within macaques, chimpanzees, and humans throughout their lifespan. We find that constitutive gene expression divergence (species differences independent of age) is comparable between humans and chimpanzees. However, humans display a 3-5 times faster evolutionary rate in divergence of developmental patterns, compared to chimpanzees. Such accelerated evolution of human brain developmental patterns (i) cannot be explained by life-history changes among species, (ii) is twice as pronounced in the prefrontal cortex than the cerebellum, (iii) preferentially affects neuron-related genes, and (iv) unlike constitutive divergence does not depend on cis-regulatory changes, but might be driven by human-specific changes in expression of trans-acting regulators. We show that developmental profiles of miRNAs, as well as their target genes, show the fastest rates of human-specific evolutionary change, and using a combination of computational and experimental methods, we identify miR-92a, miR-454, and miR-320b as possible regulators of human-specific neural development. Our results suggest that different mechanisms underlie adaptive and neutral transcriptome divergence, and that changes in the expression of a few key regulators may have been a major driving force behind rapid evolution of the human brain.
