    Angiotensin II regulates tyrosine hydroxylase activity and mRNA expression in rat mediobasal hypothalamic cultures: the role of specific protein kinases (2004)

    Notes: Dopamine secreted by hypothalamic neurons is crucial in regulating prolactin secretion from the pituitary. We have examined the ability of angiotensin II (AngII) to regulate the activity of these dopaminergic neurons and thus act as a potential physiological regulator of prolactin secretion. Using a hypothalamic cell culture preparation we determined the effect of AngII on tyrosine hydroxylase activity and expression (TOH). This is important because TOH is the rate-limiting enzyme in dopamine biosynthesis. AngII stimulated a time- and concentration-dependent increase in TOH activity which was suppressed by inhibitors able to act on protein kinase A (PKA), protein kinase C (PKC) and Ca2+/calmodulin-dependent protein kinase II (CaMPKII). An inhibitor of the mitogen-activated protein kinase (MAPK) pathway, PD 98059, reduced basal TOH activity but the AngII response was still detectable. AngII stimulation enhanced the phosphorylation of TOH at Ser19, Ser31 and Ser40. AngII also induced a time-dependent increase in TOH mRNA expression which was unaffected by inhibitors able to act on PKA and CaMPKII, but was abolished by inhibitors able to act on ERK and PKC. AngII responses were very much larger in cultures prepared from female when compared to male rat pups. Data from adult hypothalamic slices confirmed this sexual dimorphism and supported the role of the protein kinases noted above. Therefore AngII can regulate both the activity and expression of TOH in hypothalamic neurons employing multiple, but only partially overlapping, signaling pathways.

    Factors affecting resolution in scanning electron beam induced patterning of surface adsorption layers (1998)

    Notes: The monoatomic hydride layer on silicon was used as a prototype for resistless electron beam lithography. Arbitrary patterns with linewidths below 60 nm have been achieved. The variation of the linewidth with electron energy, electron dose, and substrate thickness was studied to determine the mechanisms that govern surface hydrogen desorption and subsequent pattern formation. Unlike in resist based lithography, no resolution enhancement was observed with decreasing substrate thickness. The experimental data in combination with Monte Carlo simulations of the backscattered and transmitted electrons suggest that surface hydrogen desorption and pattern formation are not strongly related to the backscattered electrons and the secondary electrons (energies 〈50 eV) associated with the backscattered electrons. © 1998 American Institute of Physics.

    Effect of 20-hydroxyecdysone on protein synthesis in wing discs ofDrosophila melanogaster (1983)

    Keywords: Drosophila melanogaster ; Wing discs ; 20-Hydroxyecdysone

    Topics: Biology
    Notes: Summary Full wing disc evagination requires about 10 h of continuous exposure to 20-hydroxyecdysone. The synthesis of two polypeptides is increased when wing discs are subjected to short exposure (4 h) to the hormone, and their synthesis is dependent on hormone. A second group of proteins increased in synthesis only after longer hormonal treatment (12 h); however, the increased synthesis of these proteins can be induced by withdrawing hormone after short exposure. The results of this study are consistent with the model of sequential gene activation by 20-hydroxyecdysone proposed by Ashburner et al. (1974).

    Retroviral producer cells cause sarcoma in severe combined immunodeficiency mice (1995)

    Notes: Abstract Direct in situ introduction of retroviral producer cells might provide a form of treatment for localized tumors. A possible undesirable consequence of this treatment could be uncontrolled proliferation of the injected producer cells. To test this possibility, severe combined immunodeficiency (SCID) mice were reconstituted with human peripheral blood lymphocytes which were marked with a retroviral vector using a coculture method. Although specific measures were taken to remove the possible contaminating producer cells, a high percentage of mice developed fibrosarcoma 2–6 weeks after reconstitution. We hypothesized that tumors arose from a small number of contaminating producer cells in the inoculum. Tumor cells were consistently DNA tetraploid, a characteristic of the producer cell line. DNA extracted from tumor tissue was found to contain the gene (neomycin phosphotransferase) used to mark the producer cell line. Furthermore, SCID mice injected with 1 × 104 producer cells developed tumors with analogous characteristics. This report indicates that the retroviral producer cell line is tumorigenic in immune-deficient animals.

    Relationship between ‘early’ and ‘late’ protein induced by 20-hydroxyecdysone in imaginal wing discs ofDrosophila melanogaster (1987)

    Notes: Abstract The insect moulting hormone, 20-hydroxyecdysone, induces the synthesis of two groups of proteins in the imaginal wing discs ofDrosophila melanogaster. The early induced group appears about 4 h after hormone treatment, the late induced group appears about 12 h after treatment. Studies using α-amanitin to inhibit mRNA synthesis during the period of hormonal treatment showed that the induction of the late proteins is dependent on mRNA synthesis and possibly the synthesis of the early proteins.
