toxins of vibrio cholerae and escherichia coli stimulate adenyl cyclase in rat fat cells. 19744366779
cholera toxin mimics melanocyte stimulating hormone in inducing differentiation in melanoma cells.cholera toxin (choleragen) and melanocyte stimulating hormone alter within hours the morphology of melanoma cells in culture, and they slow the growth of serum-stimulated cells. after 7-10 days, cells exposed to choleragen or hormone show increased size and a fibroblastic growth pattern. tyrosinase (ec 1.14.18.1; monophenol monooxygenase) activity increases after 3 days in the presence of 10(-8) m hormone or 10(-10) m choleragen. binding studies with (125)i-labeled choleragen indicate that altho ...19744366771

action of escherichia coli enterotoxin: adenylate cyclase behavior of intestinal epithelial cells in culture.heat-labile enterotoxin preparations obtained from two enteropathogenic strains of escherichia coli of porcine and human origin were shown to stimulate adenylate cyclase activity of human embryonic intestinal epithelial cells in culture. comparable results were also obtained when cholera toxin was used. the degree of enzyme stimulation was proportional to the concentration of enterotoxin. similar preparations from two strains of non-enterotoxigenic e. coli had no effect on adenylate cyclase acti ...19744364505

double-stranded ribonucleic acid from mengo virus: production, characterization, and interferon-inducing and antiviral activities in comparison with polyriboinosinic-polyribocytidylic acid.mengo virus double-stranded ribonucleic acid (dsrna) was obtained on a semi-industrial scale from infected cultures of bhk-21 cells grown in suspension. yield of the extraction and purification operations was small (about 22 mg from 10(11) cells in a 100-liter culture). physicochemical characterization of this dsrna gave an estimated molecular weight close to 4 x 10(6), a density of 1.59 (similar to that of the poliovirus dsrna), and a thermal transition midpoint of 94 c. this product was a litt ...19734364180

phosphatase activity of anaerobic organisms.anaerobic organisms were tested for phosphatase activity in different ph ranges. several groups of organisms displayed characteristic patterns. bacteroides fragilis, b. melaninogenicus, and b. ruminicola produced phosphatase with strongest activity at ph 8.6. fusobacterium mortiferum was the only species of this genus to show strong hydrolysis. the enzyme was active in both acid and alkaline ranges. the activity of gram-positive organisms was variable, the most active groups being clostridium pe ...19744363556

interaction of cholera toxin and toxin derivatives with lymphocytes. i. binding properties and interference with lectin-induced cellular stimulation.the interaction of cholera toxin and a number of toxin derivatives, containing different proportions of light and heavy toxin-composing subunits (l and h), with mouse lymphocytes was studied. experiments with [(125)i]toxin showed that a single cell can rapidly, within minutes, bind up to 40,000 molecules of toxin, the association constant was estimated to 7 +/- 4 x 10(8) liters/mol, and binding was found to be very similar at 37 degrees c and 5 degrees c. immunofluorescence studies revealed that ...19744361243

specific binding of cholera toxin to isolated intestinal microvillous membranes.a sucrose density gradient assay was used to demonstrate the specificity and saturation of the binding of [(125)i]cholera toxin to isolated intestinal microvillous membranes from rat small intestine. when the toxin is first complexed to antitoxin and then exposed to intestinal membranes, the binding of cholera toxin is inhibited. to emphasize the physiologic importance of these observations, similar concentrations of [(125)i]cholera toxin were shown to stimulate the accumulation of cyclic amp in ...19744360939

effects of prostaglandins and cholera enterotoxin on intestinal mucosal cyclic amp accumulation. evidence against an essential role for prostaglandins in the action of toxin.both cholera enterotoxin and certain prostaglandins have been shown to stimulate intestinal fluid secretion in vivo, to cause ion flux changes in vitro similar to those caused by addition of cyclic 3',5'-adenosine monophosphate (cyclic amp), and to activate intestinal mucosal adenyl cyclase. it has been suggested that the effects of the enterotoxin on intestinal cyclic amp metabolism may be indirect, and that locally synthesized prostaglandins may serve as required intermediates for the effects ...19744359941

alkaline phosphatase. possible induction by cyclic amp after cholera enterotoxin administration.the present studies were undertaken to determine the role, if any, of cyclic 3',5'-adenosine monophosphate (cyclic amp) as a chemical inducer of rat liver alkaline phosphatase. cholera enterotoxin, given intravenously to rats, led to a rapid rise in the activity of hepatic adenyl cyclase that was 7(1/2) times greater than control values in 6 h. cyclic amp levels were also significantly increased above control values while the activity of cyclic nucleotide phosphodiesterase was unchanged. hepatic ...19734356003
in vivo suppression of the immune response to alloantigen by cholera enterotoxin.the immune response of c57bl/6 mice to allogeneic (dba/2) mastocytoma cell suspensions was profoundly suppressed by intraperitoneal administration of 1 mug cholera enterotoxin 4 days after antigenic stimulation. the immune response assayed 11 days after antigen showed decreased cytolytically active thymusderived (t) lymphocytes and markedly depressed serumagglutinating titers. a comparable suppression of the immune response to skin allografts (dba/2-->c57bl/6) was also effected by cholera toxin ...19734356000

epidermal growth factor: receptors in human fibroblasts and modulation of action by cholera toxin.epidermal growth factor (egf) stimulates both dna and rna synthesis in contact-inhibited human fibroblasts. stimulation of dna synthesis is observed at concentrations as low as 3 pm, is half-maximal at 70 pm, and is maximal at 300 pm egf. the action of egf is similar to that of fetal-calf serum, but is distinguished by the time-course of stimulation and by the ability of serum to stimulate further those cells maximally stimulated by egf. cells that synthesize dna in response to physiological con ...19734355377

interferon: evidence for its glycoprotein nature.in an attempt to understand the structure of rabbit interferon, the possibility of carbohydrate being part of the molecule was tested. interferon incubated with neuraminidase from vibrio cholera is homogeneous in charge as revealed by isoelectric focusing. treatment of "asialointerferon" with galactose oxidase (ec 1.1.3.9) from dactylium dendroides and subsequent reduction with tritiated sodium borohydride yields labeled material with unimpaired antiviral activity. enzymic incorporation of n-[(1 ...19734352965

the acid and enzymic hydrolysis of o-acetylated sialic acid residues from rabbit tamm-horsfall glycoprotein.rabbit tamm-horsfall glycoprotein and bovine submaxillary glycoprotein were both found to contain sialic acid residues which are released at a slow rate by the standard conditions of acid hydrolysis. these residues are also resistant to neuraminidases from vibrio cholerae and clostridium perfringens. this behaviour was attributed to the presence of o-acetylated sialic acid, since the removal of o-acetyl groups by mild alkaline treatment normalized the subsequent release of sialic acid from rabbi ...19724349114
