摘要:
A chimeric transforming growth factor-beta termed TGF-.beta.1/.beta.2, a DNA molecule encoding TGF-.beta.1/.beta.2, a mammaliam cell transformed with said DNA molecule, and a method for producing chimeric TGF-.beta.1/.beta.2 are disclosed.
摘要:
The present invention relates to the production of large quantities of a novel chimeric TGF-.beta., termed TGF-.beta.1/.beta.2, by eucaryotic host cells transfected with recombinant DNA vectors containing the TGF-.beta.1/.beta.2 precursor coding sequence controlled by expression regulatory elements. Simian TGF-.beta.1 cDNA (Sharples et al., 1987, DNA 6:239-244) was modified so that the nucleotides encoding amino acid residue numbers 9-13, 17, 19, 25 and 26 of the mature TGF-.beta.1 sequence were hanged to the nucleotides encoding the corresponding amino acids of the mature TGF-.beta.2 structure. Simian codon usage was maintained. The chimeric TGF-.beta.1/.beta.2 of the invention induces effects on the proliferation of vascular endothelial cells equivalent to those induced by TGF-.beta.1.
摘要:
cDNA clones coding for TGF-.beta.2 which are used to construct expression vectors capable of directing the high-level expression of mature, biologically active TGF-.beta.2, as well as precursor TGF-.beta.2 forms, in transfected Chinese Hamster Ovary cells (CHO cells) and transfected COS cells are described. CHO and COS transfectants secreting TGF-.beta.2 at high levels are also described. CHO cells transfected with a plasmid vector carrying the complete 414 amino acid simian TGF-.beta.2 precursor secrete approximately 5 .mu.g per ml culture media.

The present invention provides GPCR polypeptides and polynucleotides, recombinant materials, and transgenic mice, as well as methods for their production. The polypeptides and polynucleotides are useful, for example, in methods of diagnosis and treatment of diseases and disorders. The invention also provides methods for identifying compounds (e.g., agonists or antagonists) using the GPCR polypeptides and polynucleotides of the invention, and for treating conditions associated with GPCR dysfunction with the GPCR polypeptides, polynucleotides, or identified compounds. The invention also provides diagnostic assays for detecting diseases or disorders associated with inappropriate GPCR activity or levels.
摘要:
The present invention provides compositions and methods for modulating cell division in plants. In particular, the present invention provides polynucleotides that encode REVOLUTA. In addition, REVOLUTA vectors and transformed plants are provided wherein plant cell division is modulated by expression of a REVOLUTA transgene as compared to a control population of untransformed plants. The present invention also provides methods for the isolation and identification of REVOLUTA genes from higher plants.
