    摘要: Methods for producting protein C in transgenic non-human mammals are disclosed. The protein C is modified at the two-chain cleavage site between the light and heavy chains of protein C from Lys-Arg to R1-R2-R3-R4 where R1 through R4 are individually Arg or Lys. DNA segments encoding modified protein C are introduced into the germ line of a non-human mammal, and the mammal or its female progeny produces milk containing protein C expressed from the introduced DNA segments. The protein C expressed from the introduced DNA segments has anticoagulant activity when activated. Non-human mammalian embryos and transgenic non-human mammals carrying DNA segments encoding heterologous protein C are also disclosed.

    摘要: Expression vectors and methods for cloning amino-terminal signal sequences are disclosed. These vectors and methods are useful tools for selecting, expressing and isolating previously unknown signal sequences. In turn, an orphan signal sequence can be used to clone, identify and isolate the corresponding orphan proteins that the orphan signal sequence directs to the surface of a cell. Using these expression vectors and methods, an orphan protein can be cloned in the absence of a functional assay that detects such protein.

    摘要: Human protein C molecules are modified to provide increased resistance to inactivation by human plasma factors while retaining substantially the biological activity of human protein C. The modifications are generally to the heavy chain of protein C, which chain may be substituted with a protein C heavy chain of non-human origin, such as bovine, yielding a chimeric protein C molecule. The human protein C heavy chain may also be modified to be human-like, in that at least one amino acid from a non-human sequence may be substituted for the corresponding residue(s) of the human sequence, thereby allowing the molecule to retain substantially human characteristics yet having increased resistance to inactivation. Also included are methods for producing the modified protein C molecules and pharmaceutical compositions thereof. The modified molecules, having an increased half-life in human plasma, are particularly useful for treating coagulation-related disorders, such as protein C deficiency or thrombosis, or for promoting fibrinolysis in a patient.

    摘要: Cell lines have been prepared from growth suppressor gene deficient animals. The cells include immortalized precursor cells and differentiated cells such as osteoclast precursors, osteoblast precursors, megakaryocytes, osteoclasts, osteoblasts, pancreatic α-cells, pancreatic β-cells, pancreatic δ-cells, adipocytes, macrophages, chondrocytes, dendritic cells and hepatocytes. The cells are useful for constructing cDNA and protein libraries, screening agonists and antagonists of compounds and factors that affect metabolic pathways of specific cells and generating cell-specific antibodies.

    摘要: Methods and pharmaceutical compositions for the treatment of dermatitis are disclosed. 3,4-diarylchromans and their pharmaceutically acceptable salts are formulated into medicaments, including oral and topical medicaments, which are administered to a patient suffering from dermatitis. The methods and compositions are particularly useful in the treatment of conditions characterized by hyperproliferation of keratinocytes, such as psoriasis.
