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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna-Karin Olsson; Uppsala universitet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Neuroblastoma; SH-SY5Y; differentiation; neurite; Ras; MAPK; PKC; Genetik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik; Pathology; patologi;

    Abstract : 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. READ MORE

  2. 2. Cell fate specification by Ras-mediated cell signalling in C. elegans

    University dissertation from Umeå : Umeå centrum för molekylär patogenes (UCMP) (Medicinska fakulteten)

    Author : Teresa Tiensuu; Umeå universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; cell signalling; Ras; vulva precursor cell; lin-25; sur-2; lin-1; cell fate specification; Mediator; vulva induction; transcriptional regulation; Cell- och molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi;

    Abstract : Induction of vulval fates in the C. elegans hermaphrodite is mediated by a conserved RTK/Ras/MAP kinase signalling pathway, in which the core components can be placed into a linear genetic and biochemical pathway. However, the events that occur downstream of this pathway are not yet well understood. READ MORE

  3. 3. Exoenzyme S of Pseudomonas aeruginosa cellular targets and interaction with 14-3-3

    University dissertation from Umeå : Medicinsk biovetenskap

    Author : Lubna Yasmin; Umeå universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ExoS; ADP-ribosylation; 14-3-3 protein; Pseudomonas aeruginosa; Small GTPases; RAS; RAP; MEDICINE Morphology; cell biology; pathology Pathology; MEDICIN Morfologi; cellbiologi; patologi Patologi;

    Abstract : Pseudomonas aeruginosa is an opportunistic pathogen that is a serious problem for immuno-compromised patients. Toxins such as exoenzyme (Exo) S, ExoT, ExoY and ExoU are secreted and translocated from the bacteria into the eukaryotic cell via the bacterial encoded type III secretion system. READ MORE

  4. 4. Affinity protein based inhibition of cancer related signaling pathways

    University dissertation from Stockholm : KTH

    Author : Erik Vernet; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody; cancer; endoplasmic reticulum retention; EGFR; HER2; IGF-1R; Raf; Ras; TECHNOLOGY Bioengineering; TEKNIKVETENSKAP Bioteknik;

    Abstract : Dysregulation of protein activity, caused by alterations in protein sequence, expression, or localization, is associated with numerous diseases. In order to control the activity of harmful protein entities, affinity ligands such as proteins, oligonucleotides or small molecules can be engineered to specifically interact with them to modulate their function.

  5. 5. Effects of prenatal IL-6 exposure and hyperinsulinemia on neuroendocrine regulation

    University dissertation from Stockholm : KTH

    Author : Anne-Maj Samuelsson; Göteborgs universitet.; Gothenburg University.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; interleukin-6; intrauterine exposure; HPA-axis; RAS; hippocampus; spatial learning; hypertension; insulin signaling; cardiac hypertrophy;

    Abstract : Prenatal exposure to infection is associated with several neuroendocrine disorders. We therefore wanted to elucidate if cytokines, generated in response to maternal infection, play a key mechanistic role in this associations. READ MORE
