  1. 6. Genotype-phenotype studies in brain tumors

    Författare :Soma Ghasimi; Ulrika Andersson; Beatrice Melin; Roger Henriksson; Clemens Dirven; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; Meningioma; SNP; IHC; FISH; LRIG2; EGF; EGFR; ERBB2; ER; CDKN2A B; IDH1; onkologi; Oncology;

    Sammanfattning : Meningioma and glioma are the most common primary brain tumors, but their etiologies are largely unknown. Although meningioma is usually benign, their intracranial location can lead to lethal consequences, and despite progress in surgery, radiotherapy, and chemotherapy the prognosis for patients with glioma remains poor.

  3. 7. Identification and investigations of leucine-rich repeats and immunoglobulin-like domains protein 2 (LRIG2)

    Författare :Camilla Holmlund; Håkan Hedman; Roger Henriksson; Monica Nistér; Umeå universitet; []
    Nyckelord :LRIG; PDGF; oligodendroglioma; MEDICINE; MEDICIN; onkologi; Oncology;

    Sammanfattning : Receptor tyrosine kinases (RTKs) constitute a family of proteins controlling cell growth and proliferation and whose activities are tightly controlled in normal cells. LRIG1 is a negative regulator of RTK signaling and is a proposed tumor suppressor. The aim of this thesis was to identify and study possible paralogs of LRIG1. LÄS MER

  4. 8. Cisplatin-resistance and cell death in malignant pleural mesothelioma cells

    Författare :Veronica Janson; Kjell Grankvist; Roger Henriksson; Parviz Behnam-Motlagh; Anders Johansson; Boris Zhivotovsky; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; apoptosis; BH3-only proteins; caspase; cell morphology; potassium transport; protein kinase B PKB Akt ; signalling pathways; time; Clinical chemistry; Klinisk kemi;

    Sammanfattning : Malignant pleural mesothelioma (MPM) is an aggressive, treatment-resistant tumour. Cisplatin (cis-diamminedichloroplatinum (II)) is the best single-agent chemotherapy for MPM, but platinum-based combination therapies give the best overall response rates. However, cisplatin use is limited by resistance and severe side effects. LÄS MER

  5. 9. Bacterial toxins for cancer treatment

    Författare :David Johansson; Parviz Behnam-Motlagh; Kjell Grankvist; Anders Johansson; Roger Henriksson; Bo Baldetorp; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha‐toxin; AC‐toxin; mesothelioma; lung cancer; glioma; breast cancer; caspases; MAP-Kinase; verotoxin‐1; cisplatin; apoptosis; Gb3; drug resistance; Clinical chemistry; Klinisk kemi;

    Sammanfattning : Even though anti‐cancer chemotherapy has been continuously improved during the last decades. problems with adverse effects and drug resistance still constitutes a considerable obstacle and sets a demand for new effective treatment options. LÄS MER

  7. 10. The expression and molecular functions of LRIG proteins in cancer and psoriasis

    Författare :Terese Karlsson; Håkan Hedman; Mikael Johansson; Roger Henriksson; Kim Jensen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LRIG1; LRIG2; LRIG3; LMO7 lung cancer; glioma; psoriasis; Oncology; onkologi;

    Sammanfattning : The leucine-rich repeats and immunoglobulin-like domains (LRIG) family consists of three integral membrane proteins that are important in human cancer. LRIG1 is a negative regulator of growth factor signaling. Its expression is associated with longer survival in several cancer types, and the gene has been shown to function as a tumor suppressor.
