    An α-specific gene, SAG1 is required for sexual agglutination in Saccharomyces cerevisiae (1989)
    Springer
    Current genetics 15 (1989), S. 393-398 
    Details
    ISSN: 1432-0983
    Keywords: Yeast ; Mating ; Sexual agglutination ; a-Specific mutation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Seven α-specific mutants specifically defective in sexual agglutinability were isolated. The other α mating functions exhibited by these mutants, designated sag mutants, such as the production of α pheromone and response to a mating pheromone, were normal. While the MATα sag1 cells did not agglutinate with wild-type a cells, the MATα sag1 cells did, indicating that the SAG1 gene is expressed only in α cells. The mutations were semi-dominant and fell into a single complementation group, SAG1, which was mapped near met3 on chromosome X. Complementation analysis showed that sag1 and aga1, the latter being a previously reported α-specific mutation, were mutations in the same gene.

    Calcium-binding protein regucalcin increases calcium-independent proteolytic activity in rat liver cytosol (1992)
    Springer
    Molecular and cellular biochemistry 112 (1992), S. 89-95 
    Details
    ISSN: 1573-4919
    Keywords: Regucalcin ; calcium-binding protein ; proteinase ; rat liver cytosol
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology , Medicine
    Notes: Abstract The effect of regucalcin, isolated from rat liver cytosol, on neutral proteolytic activity in the hepatic cytosol was investigated. The Ca2+-requiring proteinase required 5–10 µM Ca2+ for maximal activity in the presence of a protein substrate (globin). The proteinase activity was markedly elevated by the addition of regucalcin (0.25–2.0 µM) in the absence or presence of Ca2+ (5.0 µM) added. The effect of regucalcin, however, was the greater in the absence of Ca2+ than that in the presence. The pronounced effect of regucalcin on the proteinase activity was also seen in the presence of 1.0 mM EGTA with or without Ca2+ (5.0 µM). In the absence of Ca2+, the regucalcin-increased proteinase activity was clearly inhibited by the presence of anti-regucalcin antiserum (diluted to 240-fold), leupeptin (20 and 200 µg/ml), and heavy metals (25 µM cadmium or 25 µM zinc), although the inhibition was not complete at the concentration used. The present findings suggest that regucalcin increases proteolytic activity in rat liver cytosol, and that regucalcin may activate Ca2+-independent neutral cysteinyl-proteinase.

    Effect of β-alanyl-L-histidinato zinc on differentiation of osteoblastic MC3T3-El cells: Increases in alkaline phosphatase activity and protein concentration (1994)

    Notes: Abstract The effect of β-alany-L-histidinato zinc (AHZ) on bone cell function was investigated in osteoblastic MC3T3-E1 cells. Cells were cultured for 3 days at 37°C in a CO2 incubator in plastic dishes containing α-modified minimum essential medium supplemented with 10% fetal bovine serum. After the cultures, the medium was exchanged for that containing 0.1% bovine serum albumin plus AHZ (10−7–10−5 M) or other reagents, and the cells were cultured further for appropriate periods of time. The presence of AHZ (10−7–10−5 M) produced a remarkable increase of alkaline phosphatase activity and protein concentration in osteoblastic cells. Thus increases were seen with the prolonged cultivation (12–21 days). With the culture of 1, 3 and 12 days, the effect of AHZ (10−6 M) to increase alkaline phosphatase activity and protein concentration was more intensive than the effect of zinc sulfate, (10−6 M). The AHZ effects were completely abolished by the presence of cycloheximide (10−6 M), indicating that AHZ stimulates protein synthesis in the cells. The present study suggests that AHZ has a stimulatory effect on cell differentiation, and that this effect is partly involved on protein synthesis in osteoblastic cells.

    Enhancement of nuclear Ca2+-ATPase activity in regenerating rat liver: involvement of nuclear DNA increase (1995)

    Notes: Abstract The alteration of calcium content, Ca2+-ATPase activity, DNA content and DNA fragmentation in the nuclei of regenerating rat liver was investigated. Liver was surgically removed about 70% of that of sham-operated rats. the reduced liver weight by partial hepatectomy was completely restored at 3 days after the surgery. Regenerating liver significantly increased Ca2+-ATPase activity and DNA content in the nuclei between 1 and 5 days after hepatectomy. The nuclear calcium content was clearly increased from 2 days after hepatectomy. The increase of Ca2+-ATPase activity in regenerating liver was clearly inhibited by the presence of trifluoperazine (10 μM), staurosporine (2.5 μM) and dibucaine (10 μM), which are inhibitors of calmodulin and protein kinase, in the enzyme reaction mixture. However, the nuclear enzyme activity in normal rat liver was not significantly altered by these inhibitors. Meanwhile, the increase of nuclear DNA content in regenerating liver was completely blocked by the administration of trifluoperazine (2.5 mg/100 g body weight), suggesting an involvement of calmodulin. Now, the nuclear DNA fragmentation was significantly decreased in regenerating liver, suggesting that this decrease is partly contributed to the increase in nuclear DNA content. The present study clearly demonstrates that regenerating liver enhances nuclear Ca2+-ATPase activity and induces a corresponding elevation of nuclear calcium content. This Ca2+-signaling system may be involved in the regulation of nuclear DNA functions in regenerating rat liver.

    Characterization of zinc effect to inhibit osteoclast-like cell formation in mouse marrow culture: Interaction with dexamethasone (1997)

    Notes: Abstract The inhibitory effect of zinc compounds on osteoclast-like cell formation in mouse marrow culture in vitro was characterized. The bone marrow cells were cultured for 7 days in α-minimal essential medium containing a well-known bone resorbing agent, 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] or prostaglandin E2 (PGE2). Osteoclast-like cell formation was estimated by staining for tartrate-resistant acid phosphatase (TRACP), a marker enzyme of osteoclasts. The presence of 1,25(OH)2D3 (10-8 M) or PGE2 (10-6 M) induced a remarkable increase in osteoclast-like multinucleated cells. These increases were enhanced by the presence of dexamethasone (10-9 to 10-6 M). The dexamethasone (10-7 M)-enhanced osteoclast-like cell formation was not inhibited by the presence of zinc sulfate (10-6 M) or zinc-chelating dipeptide (β-alanyl-L-histidinato zinc; 10-6 M), although the zinc compounds had an inhibitory effect on osteoclastic formation in the absence of the steroid. The effect of dexamethasone was not seen, when the steroid was added at the later stage of culture with bone-resorbing agents. In this case, the inhibitory effect of zinc compounds was clearly revealed. This effect of zinc compounds disappeared in the presence of Ca2+-chelating agent (0.5 mM EGTA). The present study suggests that zinc compounds have an inhibitory effect at the stage of differentiation of preosteoclastic cells in bone marrow cell culture system.

    Potential sensitivity of hepatic specific protein regucalcin as a marker of chronic liver injury (1997)

    Notes: Abstract A novel calcium-binding protein regucalcin has been shown to be specifically expressed in the liver of various specifies including human. Regucalcin concentration in the serum of patients with chronic liver injury was estimated by enzyme-linked immunoadsorbent assay (ELISA) with rabbit-anti-regucalcin IgG. Serum samples were obtained from 42 persons who were diagnosed as liver disorder. Serum regucalcin concentration in all patients was in the range of 3.7-69.6 ng/ml, although regucalcin was not entirely seen in the serum of normal subjects (10 persons) without hepatitis. Meanwhile, in 18 patients with liver injury, serum glutamate-oxaloacetate transaminase (GOT) and glutamate-pyruvate transaminase (GPT) activities were normal value (less than 40 I.U./l). Serum GOT and GPT activities from 24 patients showed a comparatively higher level (50-234 I.U./l). The present results demonstrate the potential sensitivity of regucalcin as a marker of chronic liver injury. (Mol Cell Biochem 167: 187-190, 1997)
