  1. 1. Hormonal regulation of HES-1 in breast cancer cells

    Författare :Patrick Müller; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hairy and Enhancer of Split homolog 1 (HES-1) is a transcriptional repressor belonging to the basic helix-loop-helix family of proteins, and has been shown to have a pivotal role as a regulator of neurogenesis, myogenesis and hematopoiesis. HES-1 has several well conserved domains, from Drosophila to mammals, and is expressed in a variety of tissues, in both embryos and adults. LÄS MER

  3. 2. bHLH transcription factors in differentiating neuroblastoma cells

    Författare :Anna Grynfeld; Avdelningen för molekylärmedicin och genterapi; []

    Sammanfattning : Neuroblastoma is a tumor of the sympathetic nervous system, and arises during early childhood. The tumor is highly heterogeneous and evidence, such as expression of genes normally only expressed during embryonic and fetal stages, suggests that the tumor is of embryonic origin and that the tumor arises as a consequence of perturbed differentiation during the development of the sympathetic nervous system.

  4. 3. Transcriptional regulation in neuroblastoma cells under normoxic and hypoxic conditions

    Författare :Annika Jögi; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; cancerology; Cytologi; onkologi; cancer; Cytology; HIF-2; HIF-1; hypoxia; Id; HES-1; bHLH; Neuroblastoma; neuronal differentiation;

    Sammanfattning : The childhood malignancy neuroblastoma develops from early cells of the sympathetic nervous system (SNS), and the tumors often produce catecholamines. Neuroblastoma cells retain several characteristics of immature sympathetic cells including the expression of a number of transcription factors normally expressed during embryogenesis. LÄS MER

  5. 4. Notch Signaling in Human Neuroblastoma Cells

    Författare :Marie Stockhausen; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Hes-1; Medicin människa och djur ; Medicine human and vertebrates ; hypoxia; TGF-alpha; EGFR; ERK1 2; Ras MAPK; differentiation; valproic acid; ubiquilin-1; neuroblastoma; Hash-1; Cytologi; onkologi; cancer; cancerology; Cytology; Notch;

    Sammanfattning : Neuroblastoma is a childhood tumor derived from the sympathetic nervous system (SNS). It is believed that the tumors arise from cells halted in their differentiation and due to their immature phenotype; they express proteins normally only detected during embryogenesis. One such protein is Hash-1, which is required for formation of the SNS. LÄS MER

  7. 5. Antiproliferative action of estrogen receptor beta and Hes-1 in breast cancer

    Författare :Johan Hartman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Breast cancer is the most common malignancy among Swedish women. Although the mechanism behind the tumorigenesis remains unclear, estrogen receptor a (ERa) plays an important role in the progression of breast cancer and is regarded as a target for endocrine therapy. LÄS MER
