The invention provides methods to identify various types of brain cancer tissue by comparing gene expression transcriptomes in tissue samples. A sequential method to discriminate among six different types of brain cancer is described. The invention relates to the field of markers for various types of brain cancer. More particularly, it relies on a sequential system for sorting individual cancer types.

The present invention further provides compositions comprising organ-specific proteins and transcripts encoding the same, detection reagents for detecting such proteins and transcripts, and diagnostic panels, kits and arrays for measuring organ-specific proteins/transcripts in blood, biological tissue or other biological fluid.
摘要:
The present invention is directed to the identification of a biomarker specifically located in the plasma membrane of pancreatic beta cells. It was selected by a Systems Biology approach on Massively Parallel Signal Sequencing datasets obtained in human islets and Affymetrix microarray datasets on human islets, purified rat primary beta and non beta cells and insulinoma cells. Based on a set of specific features the biomarker is a unique candidate for imaging and targeting strategies to study the pancreatic beta cell mass in health and disease (T1 D, T2D, pancreatic cancers, obesity, islet transplantation, beta cell regeneration). The five specific features of the selected biomarkers are: 1) Preferentially expressed in pancreatic islets as compared to surrounding tissues; 2) Higher expression in pancreatic beta cells than in pancreatic alpha cells or than in other islet non-beta cells; 3) Expression levels in pancreatic beta cells are higher or comparable to glucokinase which is an enzyme specifically expressed in the pancreatic beta cell; 4) Located in the membrane and as such targetable with antibodies, peptides or small molecules which allows imaging, targeting and immunohistochemistry; and 5) Expression is not induced during the process of inflammation of the beta cell mass and the protein is not enriched in T-cells and dendritic cells or in other cells participating in the inflammation process.

The present invention provides a novel method for specifically isolating and separating large segments of genomic DNA that can subsequently be used to determine a genomic haplotype. The invention relies on using a solid phase having a flat surface arrayed with oligonucleotides designed to specifically hybridize to each particular haplotype of an individual sample, e.g., oligonucleotides designed to specifically hybridize with each of the two HLA-B haplotypes, HLA-A, HLA-C, HLA-DR, HLA-DQ, and the like. The genomic DNA is contacted and hybridized to the arrayed oligonucleotides to form a genomic DNA/oligonucleotide complex. The excess genomic DNA is washed away and the haplotype separated genomic DNA is denatured from the oligonucleotide probe and collected. The method of the present invention allows for the separation of genomic DNA fragments of between approximately 2 to about 4 megabases (Mb). Separation of the haplotypes of large genomic DNA fragments allows for linkage analysis of other HLA alleles and polymorphisms, microsatellite, SNPs, and the like across a large span of the HLA region, including HLA-A, -B, -C, and HLA-DRB1 regions. This linkage analysis is particularly useful when HLA typing for an individual with limited family HLA typing available.

Embodiments include an apparatus, a medical device, a method and a system. The medical device includes an ellipsoidally shaped reflector having a first focus and a second focus. The ellipsoidally shaped reflector also provides a translational coupling of electromagnetic energy from the first focus to the second focus. The medical device also includes a controllable electromagnetic energy source aligned to emit a non-biologically emitted electromagnetic energy in a proximity to the first focus.
摘要:
The present invention provides a method for identifying a thermostable polymerase having altered fidelity. The method consists of generating a random population of polymerase mutants by mutating at least one amino acid residue of a thermostable polymerase and screening the population for one or more active polymerase mutants by genetic selection. For example, the invention provides a method for identifying a thermostable polymerase having altered fidelity by mutating at least one amino acid residue in an active site O-helix of a thermostable polymerase. The invention also provides thermostable polymerases and nucleic acids encoding thermostable polymerases having altered fidelity, for example, high fidelity polymerases and low fidelity polymerases. The invention additionally provides a method for identifying one or more mutations in a gene by amplifying the gene with a high fidelity polymerase. The invention further provides a method for accurately copying repetitive nucleotide sequences using a high fidelity polymerase mutant. The invention also provides a method for diagnosing a genetic disease using a high fidelity polymerase mutant. The invention further provides a method for randomly mutagenizing a gene by amplifying the gene using a low fidelity polymerase mutant.
