  2. 21. Hypoxia-induced phenotypic modulation of human neuroblastoma cells

    Author : Linda Holmquist Mengelbier; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; reoxygenation; HIF-2a; HIF-1a; differentiation; hypoxia; neuroblastoma;

    Abstract : Neuroblastoma is a childhood tumour derived from cells of the sympathetic nervous system, which are arrested at low differentiation stages. Low differentiation stage and high tumour stage correlate to poor outcome. READ MORE

  4. 22. Hypoxic gene regulation and oncogenic pathways in neuroblastoma

    Author : Erik Fredlund; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microarray; hypoxia; MYCN; gene expression analysis; Neuroblastoma; Myc; pathway analysis; differentiation;

    Abstract : Neuroblastoma patients show remarkable clinical heterogeneity, with courses ranging from spontaneous regression to fatal tumor progression despite intense multi-modal treatment. Previous studies have shown that hypoxia pushes neuroblastoma cells towards a more immature phenotype, which correlates to aggressive disease. READ MORE

  5. 23. Approaches to Treatment of Children with Advanced Neuroblastoma

    Author : Ingrid Øra; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; drug resistance; hypoxia; apoptosis; arsenic trioxide; treatment; diagnosis; neuroblastoma; sympathetic nervous system; Pediatri; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Abstract : Children with advanced neuroblastoma are at high risk for relapse of multidrug resistant disease, despite initial response to intensive multimodality treatment. Neuroblastomas have similarities with immature neuroblasts seen during embryonic development of the sympathetic nervous system (the origin of these tumors). READ MORE

  6. 24. Effects of ellagic acid in human neuroblastoma cells

    Author : Christina Fjæraa Alfredsson; Eewa Nånberg; Karin Persson; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polyphenols; ellagic acid; neuroblastoma; SH-SY5Y cells; differentiation; proliferation; apoptosis; cell adhesion; Biomedical Sciences; Biomedicinsk vetenskap;

    Abstract : A diet rich in polyphenols has been proposed to have beneficial health effects and to reduce risk of disease. Ellagic acid, a polyphenol common in red berries and pomegranates, has potential anti-tumorigenic effects that make it interesting to further study in different cancer cell systems. READ MORE

  7. 25. Notch Signaling in Neuroblastoma and Renal Cell Carcinoma

    Author : Jonas Sjölund; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; differentiation; clear cell renal cell carcinoma; neuroblastoma; TGF-beta; migration; γ-secretase; valproic acid; cancer; Notch; ERK; von Hippel-Lindau; hypoxia;

    Abstract : The Notch signaling pathway governs cell functions essential for normal development and organogenesis. Aberrant Notch signaling has been implicated in tumorigenesis by perturbing control of proliferation, differentiation, apoptosis, migration and angiogenesis. READ MORE
