Abstract
Cisplatin resistance still remains a major obstacle in the standard chemotherapeutic approach in late-stage and metastatic testicular germ cell cancer (GCC) patients. This multifactorial and complex phenomenon arises (concomitantly) on several levels due to impaired transport, decreased adduct formation, increased DNA-repair, decreased apoptosis, or compensating pathways. Evaluation of novel therapeutic approaches and pharmacological inhibitors still remains necessary to treat cisplatin-resistant GCCs. In this chapter, we present in vitro techniques to measure cytotoxic impacts of chemotherapeutic drugs on GCC cell lines. Specifically, we will discuss the measurement of relative cell viability by XTT assay, as well as cell cycle distribution and apoptosis assay by Nicoletti- and Annexin V/PI apoptosis assay with subsequent flow cytometry, respectively, to evaluate the effects of cytotoxic treatment in GCC cell lines.
