13. A Role for the GSG Domain in Localizing Sam68 to Novel Nuclear Structures in Cancer Cell Lines
The GSG (GRP33, Sam68, GLD-1) domain is a protein module found in an expanding family of RNA-binding proteins. The numerous missense mutations identified genetically in the GSG domain support its physiological role. Although the exact function of the GSG domain is not known, it has been shown to be required for RNA binding and oligomerization. Here it is sho

14. Identification of a Rous sarcoma virus transformation-related protein in normal avian and mammalian cells.
Avian sarcoma viruses (ASV) contain a gene (src) whose protein product mediates sarcomagenic transformation. This product is a 60,000-Mr phosphoprotein designated pp60src. We have found that normal uninfected frog, chicken, rat, and human cells contain a 60,000-Mr phosphoprotein related to the product of the ASV src gene and have designated that protein pp60

15. Physiological control of repressible acid phosphatase gene transcripts in Saccharomyces cerevisiae.
We have examined the regulation of repressible acid phosphatase (APase; orthophosphoric-monoester phosphohydrolase [acid optimum], EC 3.1.3.2) in Saccharomyces cerevisiae at the physiological and molecular levels, through a series of repression and derepression experiments. We demonstrated that APase synthesis is tightly regulated throughout the growth phase

16. Cell Wall Composition and Decreased Autolytic Activity and Lysostaphin Susceptibility of Glycopeptide-Intermediate Staphylococcus aureus
The cell wall composition and autolytic properties of passage-selected glycopeptide-intermediate Staphylococcus aureus (GISA) isolates and their parent strains were studied in order to investigate the mechanism of decreased vancomycin susceptibility. GISA had relatively modest changes in peptidoglycan composition involving peptidoglycan interpeptide bridges

17. Role of Vitamin D Glucosiduronate in Calcium Homeostasis
Evidence has been presented suggesting the presence of vitamin D3 3β-glucosiduronate and 1,25-dihydroxyvitamin D3 glucosiduronate in rat bile. To evaluate the role of vitamin D glucosiduronates in calcium and phosphorus homeostasis, we synthesized vitamin D3 3β-glucosiduronate and tested its biological activity in calcium- and vitamin D-deficient rats. Aft

18. Diffusible sodium, potassium, magnesium, calcium and phosphorus in frog skeletal muscle.
A microvolumetric analytical method has been developed to measure the endogenous concentrations of diffusible elements in muscle cells. Single twitch fibres from frog muscle were skinned under oil and 0.2 nl drops of isosmotic sucrose solution, held in the tips of specially constructed pipettes, were placed in contact with the skinned fibres. After 0-10 min,

19. Inhibition of bactericidal and bacteriolytic activities of poly-D-lysine and lysozyme by chitotriose and ferric iron.
In a previous report from this laboratory (N. J. Laible and G. R. Germaine, Infect. Immun. 48:720-728, 1985), evidence was presented to suggest that the bactericidal actions of both reduced (i.e., muramidase-inactive) human placental lysozyme and the synthetic cationic homopolymer poly-D-lysine involved the activation of a bacterial endogenous activity that

20. Role of 1,25-Dihydroxyvitamin D3 on Intestinal Phosphate Absorption in Rats with a Normal Vitamin D Supply
In vitamin D-deficient rats, impaired intestinal phosphorus (P) absorption can be corrected by 1,25-dihydroxyvitamin D3[1,25-(OH)2D3]. In the present study, it was investigated whether changes in 1,25-(OH)2D3 production can influence intestinal P transport also in animals with a normal supply of vitamin D. The intestinal P absorption was evaluated in rats us
