(6) The phosphorylation pattern was affected by the addition of cholera toxin or GDP beta S to the isolated nuclei.
(7) Histopathological studies confirmed that mice fed 933cu-rev died from bilateral renal cortical tubular necrosis consistent with toxic insult, perhaps due to Shiga-like toxins.
(8) Cholera toxin-catalysed ADP-ribosylation identified two forms of Gs alpha-subunits whose labelling was about 4-fold greater in membranes from diabetic animals compared with those from lean animals.
(9) The slope of the thermal inactivation curve of enterotoxin A in beef bouillon (initial pH 6.2) was found to be approximately 27.8 C (50 F) with three different concentrations of toxin.
(10) The antibodies were used for identifying cross-reacting proteins in individual C. s. scutulatus and other Crotalus venoms and to isolate Mojave toxin.
(11) Antisera were raised against intact crotoxin (Crotalus durissus terrificus), Mojave toxin (Crotalus scutulatus scutulatus) and concolor toxin (Crotalus viridis concolor), as well as the subunits of crotoxin.
(12) Interestingly, different mechanisms of nucleated and non-nucleated TC directed lysis by CD4+ effectors were implied by distinct patterns of sensitivity to cholera toxin (CT) and cyclosporin A (CsA).
(13) The second step occurs several hours later and consists of the transactivation of adenylate cyclase and pertussis toxin genes.
(14) The toxins preferentially attenuate a slow phase of KCl-evoked glutamate release which may be associated with synaptic vesicle mobilization.
(15) Bordetella pertussis and Bacillus anthracis, two taxonomically distinct bacteria, secrete adenylate cyclase toxins that are activated by the eukaryotic protein calmodulin.
