AIMS We investigated whether radiation-induced nontargeted effects are involved in the cytotoxic effects of anticell surface monoclonal antibodies labeled with Auger electron emitters, such as iodine 125 (monoclonal antibodies labeled with (125)I [(125)I-mAbs]). RESULTS We showed that the cytotoxicity of (125)I-mAbs targeting the cell membrane of p53(+/+) HCT116 colon cancer cells is mainly d...
Reactions between purified plasminogen and streptokinase, labelled with (131)I and (125)I respectively, were investigated by polyacrylamide-gel discontinuous electrophoresis. A molecular complex consisting of both (131)I-labelled plasminogen and (125)I-labelled streptokinase migrated between plasminogen and streptokinase. This complex contained bovine plasminogen activator activity. The relativ...
Pure monoiodo ACTH-(125)I was prepared that was biologically active and free of unlabeled ACTH. Extracts of adrenal cortex that contained ACTH-sensitive adenyl cyclase, bound ACTH-(125)I; extracts that lacked the ACTH-sensitive cyclase did not bind ACTH-(125)I. Unlabeled ACTH inhibited the binding of ACTH-(125)I. Five ACTH derivatives which varied widely in biological activity were tested. All ...
The human CXC chemokines IP-10 (10-kDa interferon-inducible protein), MIG (monokine induced by human interferon-gamma), and I-TAC (interferon-inducible T cell alpha chemoattractant) attract lymphocytes through activation of CXCR3. In the studies presented here, we examined interaction of these chemokines with human CXCR3 expressed in recombinant cells and human peripheral blood lymphocytes (PBL...
In 1996, Bt-cotton (cotton expressing a Bacillus thuringiensis toxin gene) expressing the Cry1Ac protein was commercially introduced to control cotton pests. A threat to this first generation of transgenic cotton is the evolution of resistance by the insects. Second-generation Bt-cotton has been developed with either new B. thuringiensis genes or with a combination of cry genes. However, one re...
3-(Trifluoromethyl)-3-(m-[(125)I]iodophenyl)diazirine ([(125)I]TID) and [(3)H]tetracaine, an aromatic amine, are noncompetitive antagonists (NCAs) of the Torpedo species nicotinic acetylcholine receptor (nAChR), which have been shown by photoaffinity labeling to bind to a common site in the ion channel in the closed state. Although tetracaine and TID bind to the same site, the amine NCAs phency...
