    Description: We previously found that a lectin, Sambucus sieboldiana agglutinin (SSA), bound to α2,6-sialylated glycan epitopes on transferrin and inhibited anti-transferrin antibody binding to the antigen in ELISA (SSA inhibition). Here we report that SSA inhibition is applicable to immunohistochemistry, localizing α2,6-sialylated transferrin in the liver. Immunohistochemistry using anti-transferrin polyclonal antibody revealed that transferrin was detected in hepatocytes near interlobular veins. Addition of SSA lectin markedly attenuated the staining. Sialidase treatment of a liver section abolished SSA binding and concomitantly cancelled SSA inhibition, suggesting that SSA binding to glycan epitopes on the section was essential for the inhibition. To examine the importance of proximity between antigen epitopes and SSA-binding (glycosylation) sites, we prepared two anti-peptide antibodies against partial amino acid sequences of transferrin. One antibody (Tf-596Ab) is against a peptide sequence, Cys596-Ala614, which is proximal to N -glycosylation sites (Asn-432 and Asn-630). The other (Tf-120Ab) is against a peptide sequence, Val120-Cys137, distal to the sites. The staining signals of Tf-596Ab were reduced by the addition of SSA, whereas those of Tf-120Ab were reduced only a little. This result suggests that proximity of the antigen epitope to SSA binding sites is critical for SSA inhibition in immunohistochemistry.

    Description: A large fraction of protein-coding genes in metazoans undergo alternative pre-mRNA splicing in tissue- or cell-type-specific manners. Recent genome-wide approaches have identified many putative-binding sites for some of tissue-specific trans -acting splicing regulators. However, the mechanisms of splicing regulation in vivo remain largely unknown. To elucidate the modes of splicing regulation by the neuron-specific CELF family RNA-binding protein UNC-75 in Caenorhabditis elegans , we performed deep sequencing of poly(A) + RNAs from the unc-75(+)- and unc-75- mutant worms and identified more than 20 cassette and mutually exclusive exons repressed or activated by UNC-75. Motif searches revealed that (G/U)UGUUGUG stretches are enriched in the upstream and downstream introns of the UNC-75-repressed and -activated exons, respectively. Recombinant UNC-75 protein specifically binds to RNA fragments carrying the (G/U)UGUUGUG stretches in vitro . Bi-chromatic fluorescence alternative splicing reporters revealed that the UNC-75-target exons are regulated in tissue-specific and (G/U)UGUUGUG element-dependent manners in vivo . The unc-75 mutation affected the splicing reporter expression specifically in the nervous system. These results indicate that UNC-75 regulates alternative splicing of its target exons in neuron-specific and position-dependent manners through the (G/U)UGUUGUG elements in C. elegans . This study thus reveals the repertoire of target events for the CELF family in the living organism.

    Description: Powerful radio jets from active galactic nuclei are thought to be powered by the accretion of material onto the supermassive black hole (the 'central engine'). M87 is one of the closest examples of this phenomenon, and the structure of its jet has been probed on a scale of about 100 Schwarzschild radii (R(s), the radius of the event horizon). However, the location of the central black hole relative to the jet base (a bright compact radio 'core') remains elusive. Observations of other jets indicate that the central engines are located about 10(4)-10(6)R(s) upstream from the radio core. Here we report radio observations of M87 at six frequencies that allow us to achieve a positional accuracy of about 20 microarcseconds. As the jet base becomes more transparent at higher frequencies, the multifrequency position measurements of the radio core enable us to determine the upstream end of the jet. The data reveal that the central engine of M87 is located within 14-23R(s) of the radio core at 43 GHz. This implies that the site of material infall onto the black hole and the eventual origin of the jet reside in the bright compact region seen on the image at 43 GHz.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hada, Kazuhiro -- Doi, Akihiro -- Kino, Motoki -- Nagai, Hiroshi -- Hagiwara, Yoshiaki -- Kawaguchi, Noriyuki -- England -- Nature. 2011 Sep 7;477(7363):185-7. doi: 10.1038/nature10387.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Astronomical Science, The Graduate University for Advanced Studies (SOKENDAI), 2-21-1 Osawa, Mitaka, Tokyo 181-8588, Japan. kazuhiro.hada@nao.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21901008" target="_blank"〉PubMed〈/a〉

    Description: Severe childhood autosomal recessive muscular dystrophy (SCARMD) is a progressive muscle-wasting disorder common in North Africa that segregates with microsatellite markers at chromosome 13q12. Here, it is shown that a mutation in the gene encoding the 35-kilodalton dystrophin-associated glycoprotein, gamma-sarcoglycan, is likely to be the primary genetic defect in this disorder. The human gamma-sarcoglycan gene was mapped to chromosome 13q12, and deletions that alter its reading frame were identified in three families and one of four sporadic cases of SCARMD. These mutations not only affect gamma-sarcoglycan but also disrupt the integrity of the entire sarcoglycan complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noguchi, S -- McNally, E M -- Ben Othmane, K -- Hagiwara, Y -- Mizuno, Y -- Yoshida, M -- Yamamoto, H -- Bonnemann, C G -- Gussoni, E -- Denton, P H -- Kyriakides, T -- Middleton, L -- Hentati, F -- Ben Hamida, M -- Nonaka, I -- Vance, J M -- Kunkel, L M -- Ozawa, E -- NS23740/NS/NINDS NIH HHS/ -- P01-NS26630/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Nov 3;270(5237):819-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Neuroscience, National Center for Neurology and Psychiatry, Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481775" target="_blank"〉PubMed〈/a〉

    Description: Plant response to drought and hyperosmosis is mediated by the phytohormone abscisic acid (ABA), a sesquiterpene compound widely distributed in various embryophyte groups. Exogenous ABA as well as hyperosmosis activates the sucrose nonfermenting 1 (SNF1)-related protein kinase2 (SnRK2), which plays a central role in cellular responses against drought and dehydration,...

    Notes: Abstract A conditioned stimulus previously paired with electric footshock produced an increase in blood pressure in conscious, freely moving rats. The conditioned pressor response was reproducible. Intracerebroventricular injection of the nicotinic receptor antagonists hexamethonium (1–10 μg) or pentolinium (10 μg) but not the muscarinic receptor antagonist methylatropine (3 μg) produced an inhibition of the conditioned pressor response, whereas intraarterial injection of hexamethonium (10 μg) did not affect the response. Intraventricular injection of the cholinesterase inhibitor physostigmine (3–10 μg) produced an enhancement of the conditioned pressor response. These results are consistent with the possibility that central nicotinic receptors play a role in the expression of the emotionally conditioned pressor response in rats.

    Notes: Abstract A method for quantifying the effect of plane stress, plane strain, mean stress and pre-strain on fatigue crack propagation rates in plates of different thicknesses is proposed. Experimental verification was carried out on mild steel plates of 0·2, 0·4, 0·6, 0·8, 1·0, 1·2 and 1·4 mm thick specimens. The conflicting effects of variations in stress intensity factors along the crack front and changes from plane stress to plane strain conditions along the crack front are also discussed.
