Abstract: The present invention provides methods which greatly facilitate the rapidity in which cells and transgenic animals with targeted genes may be generated. The invention hastens the investigation of cells and transgenic animals bearing lowered expression of the targeted gene product, a truncated targeted gene product, a fusion protein of the targeted gene and exogenous DNA, or the expression of a different gene from the locus of the targeted gene whose product has reduced expression levels. Also disclosed is a transgenic animal having Cushing's disease. Also disclosed are diagnostic methods for detecting patients with endocrine disorders, and methods for treating or alleviating the symptoms of endocrine disorders.

Abstract: Methods and therapeutic compositions for inhibiting neoplasms by administration of a nucleic acid sequence encoding the IP-10 polypeptide.

Abstract: Methods and therapeutic compositions for treating neoplasms by administration of the polypeptide IP-10, or a suitable DNA vector encoding the polypeptide IP-10.

Abstract: A transgenic non-human eukaryotic animal whose germ cells and somatic cells contain an activated oncogene sequence introduced into the animal, or an ancestor of the animal, at an embryonic stage.

Abstract: Disclosed are methods for modulating endothelial cell proliferation. Also, disclosed are methods of detecting compounds which inhibit IP-10 and PF4 binding to a HSPG receptor.

Abstract: Disclosed is a method of isolating a ligand from a sample, the method including: providing a hybrid molecule including the receptor for the ligand covalently bonded to the first member of a specific binding pair; contacting sample with the hybrid molecule to form an affinity complex between the ligand and the hybrid molecule; and isolating the affinity complex using the second member of the specific binding pair. Also disclosed is a c-kit ligand, nucleic acid encoding such a ligand, and recombinant cells containing such nucleic acid. The c-kit ligand may be used to stimulate hematopoietic cell growth.

Abstract: A homogeneous population of cells having on average (1) a number of cell surface low-affinity heparin-binding growth factor (HBGF) sites per cell less than 20% of the number of such binding sites found on wild-type CHO-K1 cells (ATCC Accession No. CCL61), and at least three times the number of cell surface high-affinity HBGF receptors per cell found on such CHO-K1 cells; and an assay system utilizing such cells.

Abstract: Disclosed is a method for the culture of higher eukaryotic cells which are dependent for survival on an exogenous factor. The method involves co-culturing the factor-dependent cells with an immortalized eukaryotic cell that has been engineered to secrete the requisite factor.Also disclosed is a cell line of non-stromal cell origin which secretes interleukin-7.

Abstract: A novel chloride channel protein found in human breast cancer cells is disclosed. The chloride channel protein, called Mat-8, serves as a useful diagnostic reagent for the detection of breast cancer. The Mat-8 protein and chloride channel proteins generally, are useful therapeutic targets for the treatment of breast cancer.
