Resumen

For triple negative breast cancer (TNBC) patients, taxanes are the mainstays of chemotherapy but remain susceptible to resistance. Combination therapy of paclitaxel/docetaxel and tyrosine kinase inhibitors (TKIs) improves overall response rates in TNBC patients. Ixabepilone, mechanistically similar to taxanes, shows efficacy in TNBCs refractory to paclitaxel/docetaxel. Yet, there is a lack of studies on ixabepilone-TKI combinations. The first aim was to investigate the efficacy of these combinations in docetaxel-resistant MDA-MB-231 (TXT) cells and parental non-resistant MDA-MB-231 (231C) cell

The aim of this thesis was to investigate expression of putative drug resistance markers in myeloma both by examining clinical material and through the development of a xenograft model. Pgp expression was examined in 57 samples from 37 patients with myeloma. Of 23 samples at presentation and 37 at relapse, 7 and 26 respectively were Pgp positive. A myeloma xenograft model was established to examine the acute effects of cytotoxic drugs on the expression of "classical" drug resistance markers and genes involved in regulation of apoptosis. The untreated xenografts were Pgp negative, expressed low

The principle aim of this project is the investigation of metabolism and mechanisms of pentamidine resistance in trypanosomatids. An understanding of these mechanisms may allow the development of novel drugs to treat Leishmaniasis and human African trypanosomiasis (HAT), caused by the protozoan parasites Leishmania spp and Trypanosoma brucei. In this study a pentamidine resistance L. mexicana promastigote cell line was generated in vitro. This cell line was 20-fold resistant to pentamidine when compared to the parental wild type cells. Furthermore, these lines were cross resistant to other dia

Colorectal cancer (CRC) is one of the most prevalent and incident cancers worldwide and it has become soon an important public health issue. Although surgery represents the principal curative treatment, chemotherapy is one of the most important tools currently available for the treatment of CRC. 5-fluorouracil (5FU) is the chemotherapeutic agent of election for CRC treatment. Two main problems affect the outcome of cancer chemotherapy: the use of poorly specific drugs and, in a high percentage of patients, the lack of response due to drug resistance, seen as a major obstacle to improve the ove

The multidrug resistance associated proteins (MRP(human)Mrp (rat) are ATP-dependent transporters responsible for the efflux of a wide range of substrates, including endogenous compounds e.g. bilirubin, drug metabolites e.g. paracetamol glucuronide and fluorescent dyes e.g. 5 (and 6)-carboxy-2’,7’-dichlorofluorescein (CDF). Mrp1-6 (<i>abccl-6)</i> are expressed in rat liver, with Mrp2 being expressed at the highest level.

Resumen

Pancreatic cancer (PC) is known to be highly resistant to chemotherapy. Transporters, which regulate the influx and efflux of substrates across the plasma membrane, may play a role in PC drug resistance. ABC transporters are a large family of transmembrane proteins with diverse physiological functions, several of which play major roles in cancer drug resistance. Given that 90% of PC express a mutant K-ras oncogene and that PC are highly hypoxic, I postulated that constitutive K-ras activation and/or hypoxia may correlate with ABC transporter expression, which in turn may promote drug resistanc

This thesis examines the contrasting roles of genetic drift and selection on the emergence of drug resistance in Mycobacterium tuberculosis . In clinical practice some alleles of rifampicin resistance are isolated more frequently than others. To identify if this variation is due to genetic drift or selection, the mutation rate to rifampicin resistance in M. tuberculosis (H37Rv) was determined. PCR-SSCP analysis revealed only three patterns from the rifampicin resistant isolates, each pattern arising at the same mutation rate (Mann-Whitney U test P>0.5).

However, patients can be resistant to endocrine and chemotherapeutic agents, or become resistant after long term treatment.

The development of drug resistance during treatment is possibly the most important factor hampering the success of cancer therapy. In order to survive in the presence of chemotherapeutic drugs cells must quickly adapt to their altered environment. This may involve a collective stress response of interacting cells, whose mechanism is not yet clear. In the course of this work we interrogated the conceptual framework used to describe cancer and examined different aspects of drug resistance.

Le cancer de la prostate (PCa), qui représente le deuxième cancer le plus fréquent chez les hommes, n'est pas différent: les thérapies conventionnelles, y compris l'hormonothérapie et la chimiothérapie, échouent face à des tumeurs réfractaires.

Consequently, various drug resistant mutants of HIV-1 PR have been extensively studied to gain insight into the mechanisms of drug resistance.
