Project description:Patient-derived cancer cells (PDCs) were established by three-dimensional (3D) spheroid culture from testicular germ cell tumor (GCT) specimens. Microarray expression analysis revealed that cancer stem-like cell-related genes were upregulated in 3D culture condition compared with two-dimensional (2D) culture condition.
Project description:To clarify the mechanism of cisplatin resistance in testicular germ cell tumor (TGCT), cisplatin-resistant TGCT cells (N8R and G9R) were generated from parental NEC8 cells (N8P) and TGCT patient-derived cells (TGCT-PDC)(G9P), respectively, by culture in medium containing cisplatin. We used microarrays to detail the global programme of gene expression underlying cisplatin resistance and identified up- and down-regulated genes during this process.
Project description:Non-gestational choriocarcinoma (NGC) is a rare subtype of malignant germ cell tumor. We established a patient-derived xenograft (PDX) model using tumor tissue from an 18-year-old patient with NGC. Then, we performed mRNA-seq analysis using the fresh-frozen tissues of the original tumor and the PDX model.
