Journal ArticleDOI
Pulsed high-intensity focused ultrasound enhances uptake of radiolabeled monoclonal antibody to human epidermoid tumor in nude mice.
Alfia Khaibullina,Beom Jang,Haihao Sun,Nhat Le,Sarah Yu,Victor Frenkel,Jorge A. Carrasquillo,Ira Pastan,King C.P. Li,Chang H. Paik +9 more
TL;DR: It is demonstrated that pulsed-HIFU significantly enhances the delivery of 111In-MX-B3 in human epidermoid tumors xenografted in nude mice and warrant further evaluation of other treatment regimens for greater delivery enhancement.
Journal Article
Antibody engineering of recombinant Fv immunotoxins for improved targeting of cancer: disulfide-stabilized Fv immunotoxins.
Yoram Reiter,Ira Pastan +1 more
TL;DR: A new type of recombinant Fv immunotoxin is developed in which the targeting variable domains of the Fv are stabilized by an interchain disulfide bond located in structurally conserved framework positions of the VH and VL domains, termeddisulfide-stabilized Fvs (dsFv) or dsFV immunotoxins.
Journal ArticleDOI
Characterization of immunotoxins active against ovarian cancer cell lines.
Robert Pirker,David J. FitzGerald,Thomas C. Hamilton,Robert F. Ozols,Walter Joseph Laird,Arthur E. Frankel,Mark C. Willingham,Ira Pastan +7 more
TL;DR: To investigate the basis of antibody-dependent differences in activity of the various immunotoxins, antibody uptake was studied in OVCAR-2 cells, and the results indicate that antibody internalization is one important factor in the activity of immunotoxin.
Journal ArticleDOI
Identification and elimination of an immunodominant T-cell epitope in recombinant immunotoxins based on Pseudomonas exotoxin A.
Ronit Mazor,Aaron Vassall,Jaime Eberle,Richard Beers,John E. Weldon,David Venzon,Kwong Y. Tsang,Itai Benhar,Ira Pastan +8 more
TL;DR: The observation of T-cell responses in 50 of 50 individuals correlates with the frequency of antibody formation in patients with normal immune systems, and a single, highly immunodominant epitope is found in 46% (23/50) of the donors.
Journal ArticleDOI
Repression of β-Galactosidase Synthesis by Glucose in Phosphotransferase Mutants of Escherichia coli: REPRESSION IN THE ABSENCE OF GLUCOSE PHOSPHORYLATION
Ira Pastan,Robert L. Perlman +1 more
TL;DR: Glucose and α-methyl glucoside repress β-galactosidase synthesis in wild type Escherichia coli and in mutant strains deficient in Enzyme I or in the heat-stable protein of the phosphoenolpyruvate-phosphotransferase system, apparently not required for lactose utilization by E. coli.
