Abstract

Breast cancer is the second leading cause of women death worldwide. Despite the effectiveness improvement in the last decade of drugs used in this disease treatment, there are still many cases of intolerance and failure. This is because diseased cells can adapt themselves and survive the therapies used, leading to drug resistance. In addition, chemotherapy may have a less effective activity in some patients, according to genetic factors, age and environmental factors.Thus, there is still a great information requirement of all aspects about the mode of drugs action in genomic, proteomic, transcriptomic and metabolomic levels. During DSc, the candidate has developed high resolution NMR methods to analyze metabolites in breast cancer cells. The main purpose of post-doctoral is the application of these nuclear magnetic resonance - NMR techniques to evaluate the effect of three drugs used in breast cancer chemotherapy (doxorrubicin, tamoxifen and statins), in both healthy and tumor cells metabolism. Namely, this means NMR application to trace pathways of tumor and healthy cells during chemotherapy, thus helping to elucidate the metabolic effects of these medicaments.
