Technology Evaluation: Pro-542, Progenics Pharmaceuticals Inc., Muhammad Mukhtar, Zahida Parveen, Roger J Pomerantz

Department of Medicine Faculty Papers

Progenics's rCD4-IgG2 (PRO-542) is a recombinant fusion protein, which has been developed using the company's Universal Antiviral Binding (UnAB) technology, and is in phase I/II clinical trials for the treatment of human immunodeficiency virus type I (HIV-1) infection [273391]. At the beginning of 1997, Progenics received a Phase II Small Business Innovation Research Program (SBIR) grant from the National Institute of Allergy and Infectious diseases (NIAID) to fund the development of PRO-542 [236048]. A further grant of $2.7 million was awarded in August 1998 for the clinical evaluation of PRO-542 and other anti-HIV therapies [294200]. Progenics is collaborating with the …

Role Perceptions Of Occupational Therapists Providing Support And Education For Caregivers Of Persons With Dementia., Susan Toth-Cohen

Department of Occupational Therapy Faculty Papers

OBJECTIVE: This pilot study explored occupational therapists' perceptions of their roles as interventionists providing education and support for caregivers of persons with dementia. The intervention was provided in caregivers' homes as part of a larger funded study.

METHOD: Interviews were conducted with four occupational therapists to elicit their reflections on practice and their views on occupational therapy services on the basis of their experiences providing support and education for caregivers in the funded study.

RESULTS: Key themes consisted of the contrasts between the therapists' roles in the study and their customary practices and the professional and personal impact of their …

Ubinuclein, A Novel Nuclear Protein Interacting With Cellular And Viral Transcription Factors., S Aho, M Buisson, T Pajunen, Y W Ryoo, J F Giot, H Gruffat, A Sergeant, Jouni Uitto

The major target tissues for Epstein-Barr virus (EBV) infection are B lymphocytes and epithelial cells of the oropharyngeal zone. The product of the EBV BZLF1 early gene, EB1, a member of the basic leucine-zipper family of transcription factors, interacts with both viral and cellular promoters and transcription factors, modulating the reactivation of latent EBV infection. Here, we characterize a novel cellular protein interacting with the basic domains of EB1 and c-Jun, and competing of their binding to the AP1 consensus site. The transcript is present in a wide variety of human adult, fetal, and tumor tissues, and the protein is …

The Pl(A2) Polymorphism Of Integrin Beta(3) Enhances Outside-In Signaling And Adhesive Functions., K Vinod Vijayan, Pascal J. Goldschmidt-Clermont, Christine Roos, Paul F. Bray

Cardeza Foundation for Hematologic Research

Genetic factors are believed to influence the development of arterial thromboses. Because integrin alpha(IIb)beta(3) plays a crucial role in thrombus formation, we analyzed receptor adhesive properties using Chinese hamster ovary and human kidney embryonal 293 cells overexpressing the Pl(A1) or Pl(A2) polymorphic forms of alpha(IIb)beta(3). Soluble fibrinogen binding was no different between Pl(A1) and Pl(A2) cells, either in a resting state or when alpha(IIb)beta(3) was activated with anti-LIBS6. Pl(A1) and Pl(A2) cells bound equivalently to immobilized fibronectin. In contrast, significantly more Pl(A2) cells bound to immobilized fibrinogen in an alpha(IIb)beta(3)-dependent manner than did Pl(A1) cells. Disruption of the actin cytoskeleton …

A Cultivated Taste For Yeast., C Brenner

Kimmel Cancer Center Faculty Papers

The availability of complete genomic sequences of Saccharomyces cerevisiae has catalyzed a cultural change in the practice of yeast biology, providing opportunities to develop high throughput techniques to define protein function, to define drug targets, and to discover and characterize drugs.
