  1. 1. Ras-MAPK signaling in differentiating SH-SY5Y human neuroblastoma cells

    Författare :Anna-Karin Olsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Neuroblastoma; SH-SY5Y; differentiation; neurite; Ras; MAPK; PKC; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Neuroblastoma is a malignant childhood cancer, originating from sympathetic neuroblasts of the peripheral nervous system. Neuroblastoma is a heterogenous group of tumours, while some are highly malignant others can spontaneosly mature into a more benign form or regress. LÄS MER

  2. 2. RAS-MAPK syndromes - a Clinical and Molecular Investigation

    Författare :Anna-Maja Nyström; Marie-Louise Bondeson; Göran Annerén; Anna Wedell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RAS-MAPK syndromes; Noonan syndrome; Neurofibromatosis type I; cardio-facio-cutaneous syndrome; mutation; multiplex ligation-dependent probe amplification; gene; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Klinisk genetik; Clinical Genetics;

    Sammanfattning : The RAS-MAPK syndromes are a group of clinically and genetically related disorders, characterized by cardiac defects, facial dysmorphism, cutaneous abnormalities and neurocognitive impairment. The pathogenesis is dysregulation of the RAS-MAPK pathway, and several genes within the pathway are involved. LÄS MER

  3. 3. Advancing Metabolic Engineering through Combination of Systems Biology and Adaptive Evolution

    Författare :Kuk-ki Hong; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; galactose utilization; systems biology; Ras PKA signaling pathway; evolutionary engineering; pleiotropy of evolutionary strategies;

    Sammanfattning : Understanding evolutionary strategies of microorganisms may provide opportunities foradvanced strain development with the aim to produce valuable bio-products from renewablebiomass resources. Through evolutionary processes, microorganisms can attain new traitsassociated with genetic changes that may be useful for the construction of improved strains. LÄS MER

  4. 4. Metabolic regulation and anticancer drug resistance in the yeast Saccharomyces cerevisiae

    Författare :Mattias Carlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cancer is a malignant neoplastic tissue. The pyrimidine analogue 5-fluorouracil is an anticancer drug used against several types of cancer. It owes its specificity against neoplasms due to the higher rate of nutrient uptake, RNA and DNA synthesis, and in particular the higher rate of nucleobase scavenging and salvage of neoplastic cells.

  5. 5. Drosophila immune responses in a model for epithelial hypertrophy

    Författare :Robert Krautz; Ulrich Theopold; Hugo Stocker; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Biology; molekylärbiologi;

    Sammanfattning : Apoptosis, differentiation and proliferation have to be tightly balanced and thus regulated to maintain tissue homeostasis. Stress, metabolic cues, genetic variability, infections and physiological host-commensal interactions influence this balance and thus need to be integrated. Therefore, beyond the discrimination between self and non-self (i.e. LÄS MER
