  1. 1. TGF-beta signaling in cancer

    Författare :Erik Johansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TGF-β; proliferation; cancer; tumor suppressor; diffuse-type gastric carcinoma; neuroblastoma; nuclear receptor TLX; cancer stem cell; angiogenesis; ABCG2; VHL; HIF2α; hypoxia; Smad3;

    Sammanfattning : Transforming Growth Factor Beta (TGF-β) is a cytokine regulating a wide range of cellular processes such as proliferation, differentiation, and migration. At the early stages of cancer development TGF-β functions as a tumor suppressor, mainly due to its inhibitory effect on cellular growth, but during cancer progression, mutations in TGF-β signal components switches TGF-β into a promoter of cancer cell proliferation, survival and metastasis.

  3. 2. Novel aspects of neuroblastoma : to hypoxia and beyond

    Författare :Isabelle Westerlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neuroblastoma (NB) is a pediatric cancer arising from the neural crest cells forming the sympathetic nervous system. Just as other types of pediatric cancer the driving mutations of neuroblastoma are few and the tumors are instead categorized according to genetic abbreviations such as amplification, loss of heterozygosity, gains and translocations.

  4. 3. Notch signaling requiem : orchestral role of notch signaling in cancer and developmental disease

    Författare :Yat Long Tsoi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Notch signaling is an evolutionary conserved contact-dependent cell-cell communication pathway. This “contact” spans from hydra to fruit flies to human; orchestrating development, homeostasis and cancer, thus the Requiem, a song of life and death. LÄS MER

  5. 4. Notch in cancer and cancer metabolism : six degrees of intracellular turbulence

    Författare :Sebastian K-J Landor; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Notch signaling is an evolutionarily conserved cell-to-cell contact-dependent signaling mechanism in multicellular organisms directing cellular fates both in early development and adult tissues. In metazoans the Notch pathway consists of multiple paralogs of receptors and ligands constituting a complex juxtacrine communications network orchestrating organismal homeostasis. LÄS MER

  7. 5. Erythropoietin receptor in growth control and anti-estrogen resistance of estrogen receptor positive breast cancer

    Författare :Susann Reinbothe; Avdelningen för translationell cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tamoxifen resistance; proliferation; PI3k pathway; Breast cancer; erythropoietin receptor; estrogen receptor;

    Sammanfattning : The main function of Erythropoietin (EPO) and its receptor (EPOR) is the stimulation of erythropoiesis. Therefore, recombinant human EPO (rhEPO) is used to treat anemia in cancer patients, but some studies have reported that rhEPO treatment might promote tumor progression. Additionally, EPOR expression has been detected in various cancer forms. LÄS MER
