Abstract: The present invention relates to granulocyte colony-stimulating factor (“G-CSF”) analogs and compositions containing such analogs which retain the three-dimensional structure of the internal core of the four alpha helical bundle of G-CSF. In another aspect, such G-CSF analogs can also be attached with biologically active proteins to form hybrid molecules and still retain G-CSF structural integrity. Also provided are methods for determining and preparing analog or hybrid molecules and modifications.
Abstract: A fibrinolytically active metalloproteinase polypeptide (called “novel acting thrombolytic”) which is useful for blood clot lysis in vivo and methods and materials for its production by recombinant expression are described.

Abstract: The invention concerns eukaryotic cells useful in protein expression comprising (a) an inserted nucleic acid encoding a cyclin D gene product and (b) an inserted nucleic acid encoding a protein of interest, wherein the cyclin D gene product and the protein of interest are expressed in the cell. The invention also concerns a process for producing a protein of interest, which comprises (a) inserting into a eukaryotic cell a nucleic acid encoding a cyclin D gene product and a nucleic acid encoding a protein of interest; (b) culturing the cell under conditions permitting the expression of the protein of interest; and (c) isolating the protein of interest. The cells are preferably mammalian, with CHO cells most preferred. The cyclin D gene product is preferably of human origin. Suitable proteins of interest include erythropoietin (EPO), osteoprotegerin (OPG), OPG-Fc, leptin, Fc-leptin, and Novel Erythropoiesis Stimulating Protein (NESP).

Abstract: Parkinson's disease (PD) is a neurodegenerative disorder which is pathologically characterized by the presence of intracytoplasmic Lewy bodies, the major component of which are filaments consisting of &agr;-synuclein. The present invention provides &agr;-synuclein mutations which accelerate &agr;-synuclein aggregation and can thus be utilized for transgenic animal production and generation of the first progressive PD model. Also provided is an in vitro aggregation assay which can be utilized to identify &agr;-synuclein nucleation inhibitors for the treatment of PD.
Abstract: Disclosed are novel proteins, referred to as truncated glial cell line-derived neurotrophic factor (truncated GDNF) proteins, that promote dopamine uptake by dopaminergic cells and promote the survival of nerve cells. Also disclosed are processes for obtaining the truncated GDNF proteins by recombinant genetic engineering techniques.
Abstract: The invention relates generally to recombinant methods and materials for effecting the microbial production of useful polypeptides.
