21. Translational Aspects of Erythropoietin Receptor and Hypoxia-Inducible Factors in Breast Cancer
Sammanfattning : The main function of erythropoietin (EPO) is in hematopoiesis where EPO stimulates increased proliferation, survival and differentiation of erythrocytic precursors in response to hypoxia. The EPO effect is mediated via binding to the EPO receptor (EPOR), which induces activation of different intracellular signaling pathways. LÄS MER
22. Sex, hormonal factors and pancreatic cancer
Sammanfattning : Pancreatic cancer represents three percent of all incident cancer cases in developed countries, but stands the 7th most common cause of cancer related death. Worldwide, pancreatic cancer is more common among men, however in Sweden, the incidence ratio between sexes is levelling. LÄS MER
23. CYP2D6-polymorphism and effect of adjuvant tamoxifen in breast cancer patients
Sammanfattning : Adjuvant tamoxifen at the standard dose of 20 mg daily for five to ten years reduces the risk for relapse and mortality in hormone sensitive breast cancer. The effect however varies and no early marker of poor response is yet available. LÄS MER
24. The Akt/mTOR Pathway and Estrogen Receptor Phosphorylations : a crosstalk with potential to predict tamoxifen resistance in breast cancer
Sammanfattning : Estrogen receptor α content is the primary breast cancer biomarker distinguishing the patients responsive from the non-responsive to endocrine treatments. Tamoxifen is an estrogen competitor with large potential to treat breast cancer patients and prolongs time to recurrence. LÄS MER
25. Effects of sex steroids and tamoxifen on VEGF in the breast
Sammanfattning : Sex steroid exposure constitutes a risk factor for breast cancer, but little is known about the effects of sex steroids on factors mediating angiogenesis, the development of new blood vessels, in normal and malignant breast tissue. In this thesis we have investigated the effects of estradiol, progesterone, and the nonsteroidal anti-estrogen tamoxifen on vascular endothelial growth factor (VEGF) and its receptors (VEGFR-1 and VEGFR-2) in normal human breast tissue, endothelial cells, and breast cancer.
