    Use of dermestid beetles for cleaning bones (1980)
    Springer
    Calcified tissue international 31 (1980), S. 45-47

    ISSN: 1432-0827
    Keywords: Dermestid beetles ; Cleaning bones ; Rats

    Topics: Biology , Medicine , Physics
    Notes: Summary Various parts of the skeleton of normal and osteoporotic rats were compared with respect to their dry weight, ash weight, and calcium content when the bones were cleaned byDermestes maculatus beetles or manually. Both techniques gave similar results. This was also true when whole body calcium measured by neutron activation and total skeletal calcium from bones cleaned by the beetles were compared. Thus dermestid beetles are useful as a technique to clean bones, especially for the parts of the skeleton which are difficult to dissect by hand.

    Effects of castration on the bone structure of male rats: A model of osteoporosis (1980)
    Springer
    Calcified tissue international 32 (1980), S. 77-82 
    Details
    ISSN: 1432-0827
    Keywords: Osteoporosis ; Castration ; Density ; Femur ; Rats
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Physics
    Notes: Summary Forty young (23-day-old) and thirty old (1-year-old) male rats were castrated and sacrificed with controls at intervals up to 18 months of age. No differences were observed between femurs or mandibles of rats castrated at 23 days and those of controls. Year-old castrate rats developed femoral osteoporosis after 2 months, which became more pronounced 4 months after castration. This was characterized by reductions in femoral density, dry weight, dry weight per unit length, and ash weight, and by the appearance of resorption cavities in diaphyseal walls and a sparsity of trabeculae in metaphyses and epiphyses of castrate femurs. These results indicate that the year-old castrate male rat may be a valuable experimental model for studies of the treatment of osteoporosis.

    Topics: Biology , Medicine
    Notes: Summary The effect of isoproterenol (IPR) on acinar cell mitoses was studied in regenerating submandibular glands of the rat following partial extirpation. In controls, mitoses of acinar cells were markedly higher on the cut surface (reactive zone) than in the remainder of the gland through 10 ds post-operation. In experimental animals by 5 ds, a burst of mitoses of acinar cells was seen in all areas of the gland except the reactive zone. In the reactive zone, IPR appears to suppress or inhibit the induced mitoses seen in controls.

    A transcriptional switch mediated by cofactor methylation (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-11-10
    Description: We describe a molecular switch based on the controlled methylation of nucleosome and the transcriptional cofactors, the CREB-binding proteins (CBP)/p300. The CBP/p300 methylation site is localized to an arginine residue that is essential for stabilizing the structure of the KIX domain, which mediates CREB recruitment. Methylation of KIX by coactivator-associated arginine methyltransferase 1 (CARM1) blocks CREB activation by disabling the interaction between KIX and the kinase inducible domain (KID) of CREB. Thus, CARM1 functions as a corepressor in cyclic adenosine monophosphate signaling pathway via its methyltransferase activity while acting as a coactivator for nuclear hormones. These results provide strong in vivo and in vitro evidence that histone methylation plays a key role in hormone-induced gene activation and define cofactor methylation as a new regulatory mechanism in hormone signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, W -- Chen, H -- Du, K -- Asahara, H -- Tini, M -- Emerson, B M -- Montminy, M -- Evans, R M -- 9R01DK57978/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2001 Dec 21;294(5551):2507-11.

    Molecular mechanisms of the biological clock in cultured fibroblasts (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-04-17
    Description: In mammals, the central circadian pacemaker resides in the hypothalamic suprachiasmatic nucleus (SCN), but circadian oscillators also exist in peripheral tissues. Here, using wild-type and cryptochrome (mCry)-deficient cell lines derived from mCry mutant mice, we show that the peripheral oscillator in cultured fibroblasts is identical to the oscillator in the SCN in (i) temporal expression profiles of all known clock genes, (ii) the phase of the various mRNA rhythms (i.e., antiphase oscillation of Bmal1 and mPer genes), (iii) the delay between maximum mRNA levels and appearance of nuclear mPER1 and mPER2 protein, (iv) the inability to produce oscillations in the absence of functional mCry genes, and (v) the control of period length by mCRY proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yagita, K -- Tamanini, F -- van Der Horst, G T -- Okamura, H -- New York, N.Y. -- Science. 2001 Apr 13;292(5515):278-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Brain Science, Department of Brain Sciences, Kobe University Graduate School of Medicine, Chuo-ku, Kobe 650-0017, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11303101" target="_blank"〉PubMed〈/a〉

    Reversal of obesity- and diet-induced insulin resistance with salicylates or targeted disruption of Ikkbeta (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-09-05
    Description: We show that high doses of salicylates reverse hyperglycemia, hyperinsulinemia, and dyslipidemia in obese rodents by sensitizing insulin signaling. Activation or overexpression of the IkappaB kinase beta (IKKbeta) attenuated insulin signaling in cultured cells, whereas IKKbeta inhibition reversed insulin resistance. Thus, IKKbeta, rather than the cyclooxygenases, appears to be the relevant molecular target. Heterozygous deletion (Ikkbeta+/-) protected against the development of insulin resistance during high-fat feeding and in obese Lep(ob/ob) mice. These findings implicate an inflammatory process in the pathogenesis of insulin resistance in obesity and type 2 diabetes mellitus and identify the IKKbeta pathway as a target for insulin sensitization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yuan, M -- Konstantopoulos, N -- Lee, J -- Hansen, L -- Li, Z W -- Karin, M -- Shoelson, S E -- AI43477/AI/NIAID NIH HHS/ -- DK45493/DK/NIDDK NIH HHS/ -- DK51729/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2001 Aug 31;293(5535):1673-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Joslin Diabetes Center and Department of Medicine, Harvard Medical School, Boston, MA 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11533494" target="_blank"〉PubMed〈/a〉

    Prevention of chemotherapy-induced alopecia in rats by CDK inhibitors (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-01-06
    Description: Most traditional cytotoxic anticancer agents ablate the rapidly dividing epithelium of the hair follicle and induce alopecia (hair loss). Inhibition of cyclin-dependent kinase 2 (CDK2), a positive regulator of eukaryotic cell cycle progression, may represent a therapeutic strategy for prevention of chemotherapy-induced alopecia (CIA) by arresting the cell cycle and reducing the sensitivity of the epithelium to many cell cycle-active antitumor agents. Potent small-molecule inhibitors of CDK2 were developed using structure-based methods. Topical application of these compounds in a neonatal rat model of CIA reduced hair loss at the site of application in 33 to 50% of the animals. Thus, inhibition of CDK2 represents a potentially useful approach for the prevention of CIA in cancer patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, S T -- Benson, B G -- Bramson, H N -- Chapman, D E -- Dickerson, S H -- Dold, K M -- Eberwein, D J -- Edelstein, M -- Frye, S V -- Gampe Jr, R T -- Griffin, R J -- Harris, P A -- Hassell, A M -- Holmes, W D -- Hunter, R N -- Knick, V B -- Lackey, K -- Lovejoy, B -- Luzzio, M J -- Murray, D -- Parker, P -- Rocque, W J -- Shewchuk, L -- Veal, J M -- Walker, D H -- Kuyper, L F -- New York, N.Y. -- Science. 2001 Jan 5;291(5501):134-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cancer Biology, Glaxo Wellcome Research and Development, Research Triangle Park, NC 27709, USA. std41085@glaxowellcome.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11141566" target="_blank"〉PubMed〈/a〉

    Binding of GGA2 to the lysosomal enzyme sorting motif of the mannose 6-phosphate receptor (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-06-02
    Description: The GGAs are a multidomain protein family implicated in protein trafficking between the Golgi and endosomes. Here, the VHS domain of GGA2 was shown to bind to the acidic cluster-dileucine motif in the cytoplasmic tail of the cation-independent mannose 6-phosphate receptor (CI-MPR). Receptors with mutations in this motif were defective in lysosomal enzyme sorting. The hinge domain of GGA2 bound clathrin, suggesting that GGA2 could be a link between cargo molecules and clathrin-coated vesicle assembly. Thus, GGA2 binding to the CI-MPR is important for lysosomal enzyme targeting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhu, Y -- Doray, B -- Poussu, A -- Lehto, V P -- Kornfeld, S -- R01 CA-08759/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2001 Jun 1;292(5522):1716-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, Washington University School of Medicine, 660 South Euclid Avenue, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11387476" target="_blank"〉PubMed〈/a〉
