Journal ArticleDOI
Safety and antitumor activity of recombinant soluble Apo2 ligand
Avi Ashkenazi,Roger Pai,Sharon Fong,Susan Leung,David A. Lawrence,Scot A. Marsters,Christine Blackie,Ling Chang,Amy E. McMurtrey,Andrea Hebert,Laura DeForge,Iphigenia Koumenis,Derf Lewis,Louise A. Harris,Jeanine L. Bussiere,Hartmut Koeppen,Zahra Shahrokh,Ralph H. Schwall +17 more
TL;DR: Apo2L may have potent anticancer activity without significant toxicity toward normal tissues, and cooperated synergistically with the chemotherapeutic drugs 5-fluorouracil or CPT-11, causing substantial tumor regression or complete tumor ablation.
Journal ArticleDOI
Differential hepatocyte toxicity of recombinant Apo2L/TRAIL versions
David A. Lawrence,Zahra Shahrokh,Scot A. Marsters,Kirsten Achilles,Danny Shih,Barbara Mounho,Kenneth J. Hillan,Klara Totpal,Laura DeForge,Peter Schow,Jeffrey Hooley,Steve Sherwood,Roger Pai,Susan Leung,Lolo Khan,Brian Gliniak,Jeanine L. Bussiere,Craig A. Smith,Stephen S. Strom,Sean K. Kelley,Judith A. Fox,Deborah Thomas,Avi Ashkenazi +22 more
TL;DR: These findings not only provide a novel insight into the pathogenesis of the transplant-related atherosclerosis, but also point to a new therapeutic strategy that involves targeting of homing, differentiation and proliferation of putative smooth-muscle progenitor cells derived from the recipient.
Journal ArticleDOI
Receptor-selective mutants of apoptosis-inducing ligand 2/tumor necrosis factor-related apoptosis-inducing ligand reveal a greater contribution of death receptor (DR) 5 than DR4 to apoptosis signaling.
Robert F. Kelley,Klara Totpal,Stephanie Ho Lindstrom,Mary Mathieu,Karen Billeci,Laura DeForge,Roger Pai,Sarah G. Hymowitz,Avi Ashkenazi +8 more
TL;DR: It is suggested that DR5 may contribute more than DR4 to Apo2L/TRAIL-induced apoptosis in cancer cells that express both death receptors, which would suggest that the relative contribution of DR4 and DR5 to ligand- induced apoptosis is unknown.
Journal ArticleDOI
Unveiling a glycation hot spot in a recombinant humanized monoclonal antibody.
Boyan Zhang,Yi Yang,Inn H. Yuk,Roger Pai,Patrick McKay,Charles Eigenbrot,Mark S. Dennis,Viswanatham Katta,Kathleen Francissen +8 more
TL;DR: During the characterization of a recombinant humanized monoclonal antibody, electrospray mass spectrometric analysis suggested that the light chain was highly glycated, and sequence alignments and computer modeling suggest that the unusually high level of glycation of lysine residue 49 is due to a spatial proximity effect in catalyzing the Amadori rearrangement by aspartic acid residue 31 in the CDR1 on the lightchain.

Methods for making apo-2 ligand using divalent metal ions
Avi Ashkenazi,Sarah G. Hymowitz,Robert F. Kelley,Iphegenia Koumenis,Susan Leung,Mark P. O'Connell,Roger Pai,Zahra Shahrokh,Laura C. Simmons +8 more
TL;DR: In this paper, the methods of making Apo-2 ligand and formulations of Apo 2 ligand using divalent metal ions are provided, such as zinc and cobalt, which improve ligand trimer formation and stability.
