摘要:
Increased expression of Chk1 is associated with drug resistance of certain cells (e.g., cancer cells). The invention provides methods for identifying drug resistant cells by measuring the expression or activity of Chk1, methods for identifying modulators of drug resistance, and methods for modulating drug resistance by modulating the expression or activity of Chk1.

The present invention relates to methods and compositions for the diagnosis, prevention, and treatment of tumor progression in cells involved in human tumors such as melanomas, breast, gastrointestinal, lung, and bone tumors, various types of skin cancers, and other neoplastic conditions such as leukemias and lymphomas. Genes are identified that are differentially expressed in benign (e.g., non-malignant) tumor cells relative to malignant tumor cells exhibiting a high metastatic potential. Genes are also identified via the ability of their gene products to interact with gene products involved in the progression to, and/or aggressiveness of, neoplastic tumor disease states. The genes and gene products identified can be used diagnostically or for therapeutic intervention.

The present invention relates to methods and compositions for the diagnosis, prevention, and treatment of tumors and cancers (e.g., colon cancer) in mammals, e.g., humans. The invention is based on the discovery of genes that are differentially expressed in tumor cells relative to normal cells. The genes identified can be used diagnostically or as targets for therapy, and can be used to identify compounds useful in the diagnosis, prevention, and therapy of tumors and cancers.
摘要:
The present invention concerns the Caspase-8h gene and the Caspase-8i gene. The Caspase-8h gene encodes a 220 amino acid polypeptide having two FADD death effector domains. The Caspase-8i gene encodes an 81 amino acid polypeptide having one FADD death effector domain. The invention encompasses nucleic acid molecules encoding Caspase-8h or Caspase-8i, vectors containing these nucleic acid molecules, and cells harboring such vectors.

The invention provides methods for isolating cell-type specific mRNAs by selectively isolating ribosomes or proteins that bind mRNA in a cell type specific manner, and, thereby, the mRNA hound to the ribosomes or proteins that bind mRNA. Ribosomes, which are riboprotein complexes, bind mRNA that is being actively translated in cells. According to the methods of the invention, cells are engineered to express a molecularly tagged ribosomal protein or protein that binds mRNA by introducing into the cell a nucleic acid comprising a nucleotide sequence encoding a ribosomal protein or protein that binds mRNA fused to a nucleotide sequence encoding a peptide tag. The tagged ribosome or mRNA binding protein can then be isolated, along with the mRNA bound to the tagged ribosome or mRNA binding protein, and the mRNA isolated and further used for gene expression analysis. The methods of the invention facilitate the analysis and quantification of gene expression in the selected cell type present within a heterogeneous cell mixture, without the need to isolate the cells of that cell type as a preliminary step.

The invention concerns cDNA molecules encoding HRPCa 9 and HRPCa 10 both of which are constitutively expressed in the androgen-independent cell line, LN3 LNAcP and induced by testosterone in the androgen-dependent cell line, LNAcP.The invention provides isolated nucleic acid molecules encoding a polypeptide of the invention or biologically active portion thereof. The present invention also provides nucleic acid molecules which are suitable as primers or hybridization probes for the detection of nucleic acids encoding a polypeptide of the invention. The invention also provides screening assays which can be used to identify compounds useful for the treatment of prostate cancer (e.g., androgen-independent prostate cancer).

摘要:
The present invention relates to the discovery and characterization of two novel forms of Caspase-8. The first Caspase-8 of the invention, Caspase-8h, encodes a 220 amino acid polypeptide which includes two FADD death effector domains. The second caspase of the invention, Caspase-8i, encodes an 81 amino acid polypeptide having one FADD death effector domain. The invention encompasses nucleic acid molecules encoding Caspase-8h and Caspase-8i, vectors containing these nucleic acid molecules, cells harboring recombinant DNA encoding Caspase-8h and/or Caspase-8i, host fusion proteins which include Caspase-8h and/or Caspase-8i, transgenic animals which express Caspase-8h and/or Caspase-8i, therapeutic methods, purified Casapase-8h, purified Casapase-8i, therapeutic compounds and methods employing Caspase-8h and Caspase-8i, and screening methods employing Caspase-8h and Caspase-8i.
