TYLCV-Is movement in planta does not require V2 protein.
Virology 477 , 56-60, (2015) Tomato yellow leaf curl virus (TYLCV), a major tomato pathogen causing extensive crop losses, is a whitefly-transmitted geminivirus. V2 mutants of TYLCV-Is and related viruses tend to induce symptomless infection with attenuated viral DNA levels, while accumu... |

Hypoxia reduces MAX expression in endothelial cells by unproductive splicing.
FEBS Lett. 588(24) , 4784-90, (2014) The MYC-MAX-MXD network is involved in the regulation of cell differentiation and proliferation. Hypoxia affects the expression levels of several members of this network, but changes specific to MAX expression have so far not been shown. We found that in endo... |

H4 histamine receptors inhibit steroidogenesis and proliferation in Leydig cells.
J. Endocrinol. 223(3) , 241-53, (2014) The histamine H4 receptor (HRH4), discovered only 13 years ago, is considered a promising drug target for allergy, inflammation, autoimmune disorders and cancer, as reflected by a steadily growing number of scientific publications and patent applications. Alt... |

Long-distance retinoid signaling in the zebra finch brain.
PLoS ONE 9(11) , e111722, (2014) All-trans retinoic acid (ATRA), the main active metabolite of vitamin A, is a powerful signaling molecule that regulates large-scale morphogenetic processes during vertebrate embryonic development, but is also involved post-natally in regulating neural plasti... |

Mitochondrial targeting of bilirubin regulatory enzymes: An adaptive response to oxidative stress.
Toxicol. Appl. Pharmacol. 282(1) , 77-89, (2015) The intracellular level of bilirubin (BR), an endogenous antioxidant that is cytotoxic at high concentrations, is tightly controlled within the optimal therapeutic range. We have recently described a concerted intracellular BR regulation by two microsomal enz... |

The molecular structure of the left-handed supra-molecular helix of eukaryotic polyribosomes.
Nat. Commun. 5 , 5294, (2014) During protein synthesis, several ribosomes bind to a single messenger RNA (mRNA) forming large macromolecular assemblies called polyribosomes. Here we report the detailed molecular structure of a 100 MDa eukaryotic poly-ribosome complex derived from cryo ele... |

Paralcaligenes ginsengisoli sp. nov., isolated from ginseng cultivated soil.
Antonie van Leeuwenhoek 108 , 619-26, (2015) A novel bacterial strain DCY104(T) isolated from soil of a ginseng field in Yeoncheon County, Republic of Korea is described in this study. Cells were short rod-shaped, motile by mean of one polar flagellum, strictly aerobic, Gramreaction negative, oxidase an... |

Spermidine feeding decreases age-related locomotor activity loss and induces changes in lipid composition.
PLoS ONE 9(7) , e102435, (2014) Spermidine is a natural polyamine involved in many important cellular functions, whose supplementation in food or water increases life span and stress resistance in several model organisms. In this work, we expand spermidine's range of age-related beneficial ... |

Spermine oxidase maintains basal skeletal muscle gene expression and fiber size and is strongly repressed by conditions that cause skeletal muscle atrophy.
Am. J. Physiol. Endocrinol. Metab. 308(2) , E144-58, (2015) Skeletal muscle atrophy is a common and debilitating condition that remains poorly understood at the molecular level. To better understand the mechanisms of muscle atrophy, we used mouse models to search for a skeletal muscle protein that helps to maintain mu... |

Micro-scale strategy to detect spermine and spermidine by MALDI-TOF MS in foods and identification of apoptosis-related proteins by nano-flow UPLC-MS/MS after treatment with spermine and spermidine.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 978-979 , 131-7, (2015) Spermine and spermidine are multiple-nitrogen compounds found in many foods. Both compounds are essential for cell growth and human health. This study established a simple and fast method of detecting spermine and spermidine in food samples by matrix-assisted... |
