The accumulation of cargo (tau, amyloid precursor protein, neurofilaments etc.) in neurons is a hallmark of various neurodegenerative diseases while we have only little knowledge how axonal transport is regulated. Kinesin-3 UNC-104(KIF1A) is the major transporter of synaptic vesicles and recent reports suggest that a cargo itself can affect the motor's activity. Inspecting an interactome map, w...

ATP-dependent chromatin remodeling is an important facet of the regulation of gene expression in eukaryotes. Assembly of DNA into nucleosomes, the basic unit of chromatin, restricts the accessibility of cisregulatory elements in the core DNA for transcription factors that recognize and bind these sites. Chromatin remodeling ATPases use the energy derived from ATP hydrolysis to induce conformati...

Elevated expression of the drug efflux transporter ABCG2 seems to correlate with multidrug resistance of cancer cells. Specific COX-2 inhibitor celecoxib has been shown to enhance the sensitivity of cancer cells to anticancer drugs. To clarify whether ABCG2 inhibition is involved in the sensitizing effect of celecoxib, we investigated whether the expression of ABCG2 in breast cancer cell lines ...

El presente artículo analiza Diarios del odio, una instalación de Roberto Jacoby y Syd Krochmalny, desde triple perspectiva. En primer lugar como obra sitio específico que dialoga críticamente con su emplazamiento en la fuera residencia Victoria Ocampo; luego diálogo tradición poesía visual le permite capturar materializar los discursos odio circulan las redes; finalmente arte medios reflexiona...

the mrna expression of growth hormone (gh) gene in early development stages of siberian sturgeon was investigated using rt-pcr method. samples were collected from unfertilized eggs up to 50 days post hatched (dph) larvae in 11 different times. ribosomal protein l6 (rpl6) transcripts were used as the internal standard during quantification of gh mrna expression. the results showed that the gh mr...

The asymmetric localization of four maternal mRNAs - gurken, bicoid, oskar and nanos - in the Drosophila oocyte is essential for the development of the embryonic body axes. Fluorescent imaging methods are now being used to visualize these mRNAs in living tissue, allowing dynamic analysis of their behaviors throughout the process of localization. This review summarizes recent findings from such ...

Soybean is one of the most important crops in Brazil and continuously generates demands for production technologies, such as cultivars resistant to diseases. In recent years, the Asian rust fungus (Phakopsora pachyrhizi Syd. & P. Syd 1914) has caused severe yield losses and the development of resistant cultivars is the best means of control. Understanding the genetic control and estimating para...
