  1. 1. Development of Techniques for Characterization, Detection and Protein Profiling of Extracellular Vesicles

    Författare :Sara Cavallaro; Jan Linnros; Apurba Dev; Hakho Lee; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular vesicles; streaming current; fluorescence microscopy; atomic force microscopy; scanning electron microscopy; protein profiling; size profiling; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Nanosized extracellular vesicles (EVs, ∼30-2000 nm) have emerged as important mediators of intercellular communication, offering opportunities for both diagnostics and therapeutics. In particular, small EVs generated from the endolysosomal pathway (∼30-150 nm), referred to as exosomes, have attracted interest as a suitable biomarker for cancer diagnostics and treatment monitoring based on minimally invasive liquid biopsies.

    Sammanfattning : The Human Protein Atlas project is a Swedish research initiative that uses antibody-based proteomics for large scale protein profiling in human tissues and cells. Affinity-purified antibodies are produced within the project and used for immunohistochemical staining on tissue micro arrays (TMAs) in order to map the human proteome and publish the result in a protein atlas (www.

  3. 3. Purification, profiling and bioengineering of extracellular vesicles

    Författare :Giulia Corso; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : The nano-sized membrane enclosed extracellular vesicles (EVs) transfer macromolecular information in the form of proteins, nucleic acids and lipids across cells. They are important mediators of cell-to-cell communication, but their relatively small size makes EV isolation and down-stream analysis challenging. LÄS MER

  4. 4. Interrogation of Nucleic Acids by Parallel Threading

    Författare :Erik Pettersson; Joakim Lundeberg; Afshin Ahmadian; Ann-Christine Syvänen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; genotyping; multiplex amplification; trinucleotide threading; single nucleotide polymorphism; genotype calling; Expectation-Maximization; protein-epitope signature tag; expression profiling; Human Protein Atlas; pooled genomic DNA; Pyrosequencing; 454; allelotyping; association studies; bioinformatics; Bioengineering; Bioteknik;

    Sammanfattning : Advancements in the field of biotechnology are expanding the scientific horizon and a promising era is envisioned with personalized medicine for improved health. The amount of genetic data is growing at an ever-escalating pace due to the availability of novel technologies that allow massively parallel sequencing and whole-genome genotyping, that are supported by the advancements in computer science and information technologies.

  5. 5. Endosonography and pretreatment tumor profiling - from sampling, staining, to sequencing

    Författare :Per Hedenström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :endosonography; fine-needle biopsy; pancreatic neoplasms; gastrointestinal stromal tumors; KIT; PDGFRA; Ki-67; imatinib; neoadjuvant therapy;

    Sammanfattning : Background and aims: Endosonography-guided fine needle aspiration (EUS-FNA) is imperfect in diagnosing solid pancreatic lesions (SPL) and subepithelial lesions (SEL) including gastrointestinal stromal tumors (GIST). In GISTs, imatinib therapy is effective only in variants of oncogenes KIT and PDGFRA. LÄS MER
