ELDERLY PERSONS LIVING WITH CANCER. Quality of life and lived experience.
Over the coming decades, the numbers of elderly will increase, and through improved lifestyles and better treatment longevity has increased, and with it, the risk of contracting cancer. How elderly people live with cancer has until now attracted limited research. The overall aim of this thesis was …

Invasion and Proliferation in Malignant Cells
Two key events in the oncogenic process of tumor cells are to acquire uncontrolled proliferation and invasive properties. This allows the tumor to grow and invade beyond the tissue from which the tumor cells originate. We here specifically studied p16 and ERK1/2 with special focus on and the …

Soft Tissue Sarcoma Patterns multiplicity, heterogeneity and growth characteristics
Soft tissue sarcomas (STS) represent a group of rare and heterogenous tumors that optimally should be diagnosed and treated within multidisciplinary teams. This thesis has studied various aspects ? pathological, genetical, and clinical ? of STS. In study I, we demonstrated that 20% of the patients …

Regulation of PKCalpha and the role of PKC in neuroblastoma cell migration
Members of the protein kinase C (PKC) family of serine/threonine kinases play critical roles in cellular regulation. Depending on differences in regulation, PKCs can be divided into classical (alpha, betaI, betaII and gamma), novel (delta, epsilon, eta and theta) and atypical (zeta and iota/lambda) …

Wnt-5a signaling in breast cancer metastasis
Breast cancer is the most common form of malignancy affecting women in the Western world. Today, anticancer treatment can control primary breast tumors, but treatment and prevention of metastatic disease still represents a major challenge in the management of breast cancer patients. It has been …

Role of cyclin D1 as an estrogen receptor cofactor and the influence of hypoxia on estrogen receptor regulation, with focus on prognositic and treatment predictive features in breast cancer
Estrogen receptor (ER) status can define breast cancer patients who would benefit from adjuvant tamoxifen therapy. However, resistance to tamoxifen is often observed and possible mechanisms may be loss or reduction of ER, dysfunctional ER- signaling and ligand independent activation of the …

Transcriptional Regulation by Hypoxia-Inducible Factors in Tumor Cells
Cancer is a major cause of human morbidity and mortality, and the risk of developing cancer is about one in three life times. Neuroblastoma is the most common extra-cranial solid tumor among children and arises from early sympathetic nervous system (SNS) cells arrested in their development. …

Genetic Profiling in Soft Tissue Sarcoma
Soft tissue sarcomas (STS) are a heterogeneous group of highly malignant mesenchymal tumors that account for ~1% of all malignancies. Frequent heterogeneity and pleomorphism along with suboptimal diagnostic reproducibility and insufficient prognostic markers make clinical management of these tumors …

Localisation of Protein Kinase C in Apoptosis and Neurite Outgrowth
Protein kinase C (PKC) is a family of serine/threonine kinases, which are subgrouped into classical (a, bI, bII, g), novel (d, e, h, q) and atypical (z, i/l) isoforms. One major aim of this thesis work was to investigate if altered levels of PKC isoforms influence the apoptotic responses of …

The Wilms' tumor gene 1 (WT1) and leukemia -new insights and further complexity
The Wilms tumor gene 1 (WT1) encodes a zinc-finger containing transcription factor which is highly expressed in immature hematopoietic progenitor cells. A high expression of WT1 and the presence of somatic mutations in acute leukemia indicate a role for WT1 in the pathogenesis of leukemia. The …

MOLECULAR PROFILING OF UROTHELIAL CARCINOMA
The general aim of this thesis was to molecularly characterize urothelial carcinoma (UC) at the transcriptional level using gene expression microarrays to improve the classification and pathogenetic understanding of this disease. In the first two studies (Articles I and II), gene expression …

REGULATED UPTAKE OF BIOPOLYMERS Role of cell surface proteoglycans Implications for drug and gene delivery
Cells continuously export, import, and recycle molecules over the plasma membrane. Internalization, i.e. cellular import of extracellular material, is a fundamental process, which provides cells with nutrients and enables the immune cells of higher organisms to remove debris, sample their …

Notch Signaling in Human Neuroblastoma Cells
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, …

Photodynamic Therapy utilizing Interstitial Light Delivery Combined with Spectroscopic Methods
Since cancer continues to plague humanity there is large need for development of modalities for both diagnosis and therapy. Most of the currently available methods suffer from serious disadvantages. The treatments, e.g. ionising radiation, chemotherapy, surgery, may themselves induce malignancies …

Prognostic factors in soft tissue sarcoma. Tissue microarray for immunostaining, the importance of whole-tumor sections and time-dependence.
In adult soft tissue sarcoma (STS) of the extremities and trunk wall, improved prognostic factors are needed to identify patients at high-risk for metastasis. Various factors are included in the many prognostic systems currently in use and the prognostic value of immunohistochemical (IHC) …
