Cognitive Functions: Human vs. Animal – 4:1 Advantage |-FAM72–SRGAP2-|
Ho, Nguyen Thi Thanh,Kim, Pok-Son,Kutzner, Arne,Heese, Klaus Springer-Verlag 2017 Journal of molecular neuroscience Vol.61 No.4
<P>With the advent of computational genomics, an intensive search is underway for unique biomarkers for Homo sapiens that could be used to differentiate taxa within the Hominoidea, in particular to distinguish Homo from the apes (Pan, Gorilla, Pongo, and Hylobates) and species or subspecies within the genus Homo (H. sapiens, H. heidelbergensis, H. neanderthalensis, H. erectus, and the Denisovans). Here, we suggest that the |-FAM72-SRGAP2-| (family with sequence similarity 72/SLIT-ROBO Rho GTPase activating protein 2) gene pair is a unique molecular biomarker for the genus Homo that could also help to place Australopithecus at its most appropriate place within the phylogenetic tree and may explain the distinctive higher brain cognitive functions of humans.</P>

<P><B>Abstract</B></P><P>Due to an aging society with an increased dementia-induced threat to higher cognitive functions, it has become imperative to understand the molecular and cellular events controlling the memory and learning processes in the brain. Here, we suggest that the novel master gene pair |-SRGAP2-FAM72-| (SLIT-ROBO Rho GTPase activating the protein 2, family with sequence similarity to 72) reveals a new dogma for the regulation of neural stem cell (NSC) gene expression and is a distinctive player in the control of human brain plasticity. Insight into the specific regulation of the brain-specific neural master gene |-SRGAP2-FAM72-| may essentially contribute to novel therapeutic approaches to restore or improve higher cognitive functions.</P>

The widespread application of triazole fungicides (TFs) in agricultural practices can result in the considerable accumulation of active compound residues in the soil and a subsequent negative impact on the soil microbiota and crop health. In this study, we isolated three TF-degrading bacterial strains from contaminated agricultural soils and identified them as Klebsiella sp., Pseudomonas sp., and Citrobacter sp. based on analysis of morphological characteristics and 16S rRNA gene sequences. The strains used three common TFs, namely hexaconazole, difenoconazole, and propiconazole, as their only sources of carbon and energy for growth in a liquid mineral salt medium, with high concentrations (~ 500 mg/l) of each TF. In addition to the ability to degrade fungicides, the isolates also exhibited plant growth-promoting characteristics, such as nitrogen fixation, indole acetic acid production, phosphate dissolution, and cellulose degradation. The synergistic combination of three bacterial isolates significantly improved plant growth and development with an increased survival rate (57%), and achieved TF degradation ranging from 85.83 to 96.59% at a concentration of approximately 50 mg/kg of each TF within 45 days in the soil-plant system. Based on these findings, the three strains and their microbial consortium show promise for application in biofertilizers, to improve soil health and facilitate optimal plant growth.
Anti-inflammatory Asterosaponins from the Starfish <i>Astropecten monacanthus</i>

<P>Four new asterosaponins, astrosteriosides A–D (<B>1</B>–<B>3</B> and <B>5</B>), and two known compounds, psilasteroside (<B>4</B>) and marthasteroside B (<B>6</B>), were isolated from the MeOH extract of the edible Vietnamese starfish <I>Astropecten monacanthus</I>. Their structures were elucidated by chemical and spectroscopic methods including FTICRMS and 1D and 2D NMR experiments. The effects of the extracts and isolated compounds on pro-inflammatory cytokines were evaluated by measuring the production of IL-12 p40, IL-6, and TNF-α in LPS-stimulated bone marrow-derived dendritic cells. Compounds <B>1</B>, <B>5</B>, and <B>6</B> exhibited potent anti-inflammatory activity comparable to that of the positive control. Further studies are required to confirm efficacy <I>in vivo</I> and the mechanism of effects. Such potent anti-inflammatory activities render compounds <B>1</B>, <B>5</B>, and <B>6</B> important materials for further applications including complementary inflammation remedies and/or functional foods and nutraceuticals.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jnprdf/2013/jnprdf.2013.76.issue-9/np400492a/production/images/medium/np-2013-00492a_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/np400492a'>ACS Electronic Supporting Info</A></P>
Anti-inflammatory tirucallane saponins from Paramignya scandens.
Phan, Nguyen Huu Toan,Thuan, Nguyen Thi Dieu,Ngoc, Ninh Thi,Thao, Nguyen Phuong,Kim, Sohyun,Koh, Young Sang,Thanh, Nguyen Van,Cuong, Nguyen Xuan,Nam, Nguyen Hoai,Kiem, Phan Van,Kim, Young Ho,Minh, Cha Pharmaceutical Society of Japan 2015 Chemical & pharmaceutical bulletin Vol.63 No.7
<P>Five new tirucallane saponins, paramignyosides A-E (1-5), were isolated from the water fraction of the Paramignya scandens stem and leaves. Their structures were elucidated on the basis of spectroscopic evidence including high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) and one dimensional (1D)- and 2D-NMR. The effects of isolated compounds on pro-inflammatory cytokines were evaluated by measuring the production of interleukin (IL)-12 p40, IL-6, and tumor necrosis factor-α (TNF-α) in lipopolysaccharide (LPS)-stimulated bone marrow-derived dendritic cells (BMDCs). Paramignyoside C (3) exhibited selective and potent inhibitory effect (IC50=5.030.19??M) on the production of IL-12 p40 comparable to that of the positive control, SB203580 (IC50=5.000.16??M). Further studies are required to confirm efficacy in vivo and the mechanism of anti-inflammatory effects.</P>
