ROLE OF GLUTATHIONE IN THE MULTIDRUG RESISTANCE IN CANCER

Multidrug resistance is the main problem in anticancer therapy. Cancer cells use many defense strategies in order to survive chemotherapy. Among known multidrug resistance mechanisms the most important are: drug detoxification inside the cell using II phase detoxifying enzymes and active transport of the drug to the extracellular environment. Cancer cells may be also less sensitive to proapoptotic signals and have different intracellular drug distribution, which makes them more resistant to anticancer drugs.

APOPTOSIS – TARGETED ANTICANCER THERAPY

Apoptosis is the major form of cell suicide. Most conventional anticancer agents induce apoptosis indirectly. Although chemiotherapeutic drugs should selectively kill only tumor cells, normal cells are often susceptible to cytotoxic or cytostatic effects of these agents. This is a reason of potentially harmful side effects including inflammation and damage to the surrounding normal tissue. A new therapeu- tic approach in cancer treatment is the use of substances that stimulate cytokine production, angiogenesis inhibitors, gene therapies, antisense oligonucleotides and monoclonal antibodies.
