  2. 1. Proteolytic processing of the Alzheimer APP protein family during neuronal differentiation

    Author : Sofia Holback; Kerstin Iverfeldt; Nigel Hooper; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APP; APLP1; APLP2; differentiation; processing; retinoic acid; secretase; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Abstract : Increased amyloid-β (Aβ) load in the brain, neurite degeneration, neuronal loss, and decreased levels of several neurotrophins are among the characteristics of Alzheimer’s disease (AD). Generation of Aβ occurs when the amyloid precursor protein (APP) is proteolytically processed by β- and γ-secretases in the amyloidogenic pathway. READ MORE

  4. 2. Processing of the amyloid precursor protein and its paralogues amyloid precursor-like proteins 1 and 2

    Author : Linda Adlerz; Kerstin Iverfeldt; Richard Cowburn; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APP; APLP1; APLP2; Alzheimer s disease; Amyloid β-peptide; Processing; RA; BDNF; IGF-1; curcumin; PI3-K; MAPK; cdk5; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Abstract : Alzheimer’s disease (AD) is a neurodegenerative disorder which is histopathologically characterised by amyloid plaques and neurofibrillary tangles. Amyloid plaques consist of the amyloid β-peptide (Aβ) that can form aggregates in the brain. Aβ is generated from the amyloid precursor protein (APP) through proteolytic cleavage. READ MORE

  5. 3. Regulation of tartrate-resistant purple acid phosphatase by proteolytic processing in rat

    Author : Jenny Ljusberg-Sjölander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Purple acid phosphatase; enzyme catalysis; proteolytic processing;

    Abstract : Purple acid phosphatase (PAP) is an iron-containing binuclear acid metallohydrolase with a characteristic purple colour, also referred to as tartrate-resistant acid phosphatase (TRAP), uteroferrin or type 5 acid phosphatase. PAP is highly expressed in osteoclasts and has a role in bone resorption. READ MORE

  6. 4. Colonic mucus structure and processing

    Author : Elisabeth E. L. Nyström; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucus; CLCA1; Goblet cell; Spdef;

    Abstract : The mucus layer covering the colonic epithelium creates a crucial first line of defense against the gut residing bacteria. Several lines of evidence suggest that a functional mucus layer is essential for health. For example, it is. suggested that ulcerative colitis is correlated with mucus layer defects. READ MORE

  7. 5. Tumor biological aspects of the mucin-like glycoprotein CD43

    Author : Sirle Laos; Göteborgs universitet; []
    Keywords : CD43; leukosialin; sialophorin; mucin; colon adenoma; proteolytic processing; ; NF-kappaB; p65; chemokine; p53; ARF; Fas; apoptosis; transformation;

    Abstract : Cancer cells overexpress aberrant forms and amounts of mucins, which contribute to tumor development by regulating cell growth, survival, adhesion, invasion and immune responses. CD43, a type I transmembrane protein, is a mucin-like molecule expressed under normal physiological conditions by most hematopoietic cell types. READ MORE
