Lead activates calmodulin sensitive processes
(Elsevier, 1983-09-05)
The effect of lead on two calcium sensitive processes was determined. Micromolar concentrations of lead successfully replaced calcium in the activation of calmodulin-sensitive phosphodiesterase and in the promotion of ...
Linkage of the structural gene for uroporphyrinogen I synthase to markers on mouse chromosome 9 in a cross between feral and inbred mice
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1982-08)
The Ups locus has been mapped to mouse chromosome 9 in a three-point cross. The observed gene order is centromere- Ups -15- Mpi-1 -22- Mod-1 . Ups is unlinked to Lv , which encodes the previous enzyme in the heme biosynthesis ...
Degenerative and regenerative changes in the trochlear nerve of goldfish
(Kluwer Academic Publishers; Chapman and Hall Ltd ; Springer Science+Business Media, 1984-08)
The features of unlesioned and lesioned trochlear nerves of goldfish have been examined electron microscopically. Lesioned nerves were studied between 1 and 107 days after cutting or crushing the nerve. 1. Unlesioned nerves ...
Biosynthesis of alkyl-ether containing lipid from dihydroxyacetone phosphate
(Elsevier, 1969-10-22)
A lipid, stable to alkaline methanolysis, is formed when liver mitochondria or brain microsomes are incubated with dihydroxyacetone phosphate, long chain alcohol, ATP, CoA, NaF and Mg++. The lipid has been identified as ...
Stimulation of fibroblast proliferation by thrombospondin
(Elsevier, 1989-08-30)
Thrombospondin purified from human platelets was examined for its ability to promote proliferation of human dermal fibroblasts. The results show that thrombospondin could stimulate the incorporation of [3H]thymidine by ...
More TORC for the gluconeogenic engine
(Wiley Subscription Services, Inc., A Wiley Company, 2006-03)
Hepatic gluconeogenesis plays a key role in the maintenance of glucose homeostasis. The hormone glucagon stimulates this process, whereas insulin and adiponectin are inhibitory. In a recent report, Koo et al identify the ...
The chemical synthesis of 2-keto-3-deoxy-octonate and its cleavage by a specific aldolase
(Elsevier, 1963-05-22)
We have previously reported (Heath and Ghalambor, 1963) the occurrence of 2-keto-3-deoxy-octonate (KDO) as a glycosidically-bound constituent of cell wall lipopolysaccharide (LPS) of 0111-B4 and the enzymatic synthesis ...
