Cyclosporine a inhibits TNF production without decreasing TNF mRNA levels
(Elsevier, 1989-06-15)
The role of cytokines in health and disease has received increasing attention and numberous investigations have explored the regulation of cytokine gene expression. Tumor necrosis factor-[alpha] (TNF) has received particular ...
POMC in rhesus anterior pituitary and plasma: Evidence of N-acetylated [beta]-endorphin and [alpha]-MSH
(Elsevier, 1983)
Pro-opiomelanocortin (POMC) related peptides have been studied in rat tissue and plasma, but they have not been well characterized in the rhesus monkey. Since monkey pituitary may be more similar to the human pituitary ...
Saturation behavior of superoxide dismutation catalyzed by the iron containing superoxide dismutase of E. coli B
(Elsevier, 1981-05-15)
SummaryThe iron containing superoxide dismutase from E. coli B is shown to catalyze superoxide dismutation by a mechanism which exhibits saturation kinetics. This behavior is quite different from that observed previously ...
Bradykinin-stimulated changes in inositol phosphate mass in renal papillary collecting tubule cells
(Elsevier, 1987-06-30)
The effect of bradykinin on changes in the chemical levels of -inositol polyphosphates in renal papillary collecting tubules was investigated. -inositol phosphate mass was determined by means of an enzymatic, fluorometric ...
Rearrangement, amplification, and assortment of mitochondrial DNA molecules in cultured cells of Brassica campestris
(Springer-Verlag, 1989-01)
We compared Brassica campestris mitochondrial and chloroplast DNAs from whole plants and from a 2-year-old cell culture. No differences were observed in the chloroplast DNAs (cpDNAs), whereas the culture mitochondrial DNA ...
Near stoichiometric, irreversible inactivation of bacterial collagenases by o-chloranil (3,4,5,6-tetrachloro-1,2-benzoquinone)
(Elsevier, 1988-05-31)
SummaryThe hydrogen-abstracting quinone derivative 3,4,5,6-tetrachloro-1,2-benzoquinone (o-chloranil) caused a strong, near stoichiometric, irreversible inactivation of the collagenases from Bacillus cereus, Clostridium ...
Cross-reactions among carbonic anhydrases I, II, and III studied by binding tests and with monoclonal antibodies
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1982-08)
Cross-reactions among carbonic anhydrases (CAs) I, II, and III were studied using a variety of antisera: (1) a rabbit antiserum to bovine CA III, (2) mouse antisera to human CA I, CA II, and CA III; and (3) five monoclonal ...
Enzymatic inactivation of bradykinin by rat brain neuronal perikarya
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1989-09)
1. Bradykinin (Bk; Arg 1 -Pro 2 -Pro 3 -Gly 4 -Phe 5 -Ser 6 -Pro 7 -Phe 8 -Arg 8 ) inactivation by bulk isolated neurons from rat brain is described.
Identification of gonadotropin inducible, high density lipoprotein receptors in the solubilized membranes from rat ovary
(Elsevier, 1986-01-29)
Specific receptors for high density lipoproteins (HDL3) were solubilized from membranes of rat corpus luteum using different detergents. Among the detergents tested, octyl-[beta]-D-glucoside (40 mM) was most effective with ...
Growth conditions of F9 embryonal carcinoma cells affect the degree of DNA methylation
(Kluwer Academic Publishers; Dr W. Junk Publishers ; Springer Science+Business Media, 1984-12)
We have investigated differences in C * pG methylation between F9 embryonal carcinoma cells in vitro and as tumor cells grown in vivo using Msp I and Hpa II restriction isoschizomers. Southerns were hybridized with two low ...
