This volume presents the latest techniques used to study germ cell tumors (GCTs), including histopathology; in vitro and in vivo techniques for investigating GCT biology; novel methods for detecting minimal residual diseases; and sequencing considerations as they apply to GCTs. Chapters cover topics such as clinical applications of immunohistochemistry in GCTs in men; fluorescence in situ hybridization (FISH) detection of chromosomal 12p anomalies in testicular GCTs; evaluation of chemotherapeutic drugs for treatment of (cisplatin-resistant) germ cell cancer cell lines; targeted methylation analyses; and circulating microRNA panel for malignant GCT diagnosis and monitoring. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, Testicular Germ Cell Tumors: Methods and Protocols provides valuable information that is useful for both novice and expert GCT researchers interested in learning more about this field.
