  1. 21. Defining the role of CAAX protein proteolysis and methylation in the pathogenesis and treatment of progeria

    Författare :Xue Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hutchinson-Gilford progeria syndrome (HGPS) is a rare childhood disease characterized by failure to thrive, bone abnormalities, hair loss, and a shortened life span due to cardiovascular disease, and nuclear shape abnormalities in cultured cells. HGPS is caused by de-novo mutations in LMNA, the gene encoding prelamin A. LÄS MER

  3. 22. Rational modifications of cell-penetrating peptides for drug delivery : Applications in tumor targeting and oligonucleotide delivery

    Författare :Maarja Mäe; Ülo Langel; Edvard Smith; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-penetrating peptide; oligonucleotide; drug delivery; tumor targeting; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : High molecular weight biomolecules are becoming important in the development of new therapeutics. However, their size and nature creates a major limitation for their application – poor penetration through biological membranes. LÄS MER

  4. 23. Substance P Endopeptidase : Purification and Characterizataion of Enzyme Activity and Evaluation of its Function during Stressful Condition

    Författare :Krister Karlsson; Lars Oreland; Fred Nyberg; Tsukasa Sakurada; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Substance P Endopeptidase; Neuropeptide; Central Nervous System; Purification; Drug Dependence; Heat Stress; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : The purification and biochemical characterization of the substance P (SP) hydrolyzing enzyme, substance P endopeptidase (SPE), have been carried out; with subsequent orientation in neurobiological fundamental processes involved in opioid dependence, withdrawal, and heat-stress.SPE was purified from rat spinal cord, human spinal cord and cerebrospinal fluid (CSF), rat ventral tegemental area (VTA), and rat hippocampus.

  5. 24. Different types of γ-secretes complexes and their effect on substrate processing

    Författare :Annelie Pamrén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The γ-secretase complex is a transmembrane aspartyl protease that generates the Alzheimer disease (AD) related amyloid β-peptide (Aβ) from the amyloid precursor protein (APP). The γ-secretase complex cleaves APP at two different sites (γ- and ε-sites) generating Aβ-peptides and the APP intracellular domain (AICD). LÄS MER

  7. 25. Modeling the Interaction Space of Biological Macromolecules: A Proteochemometric Approach : Applications for Drug Discovery and Development

    Författare :Aleksejs Kontijevskis; Jarl Wikberg; Jan Komorowski; Robert Glen; Uppsala universitet; []
    Nyckelord :Bioinformatics; proteochemometrics; bioinformatics; chemoinformatics; chemical space; QSAR; retroviral proteases; HIV-1; drug resistance; pharmacogenomics; cytochrome P450; GPCRs; melanocortin receptors; interactome; machine-learning; rough sets; Bioinformatik;

    Sammanfattning : Molecular interactions lie at the heart of myriad biological processes. Knowledge of molecular recognition processes and the ability to model and predict interactions of any biological molecule to any chemical compound are the key for better understanding of cell functions and discovery of more efficacious medicines.
