Abstract 3394: In-depth gene expression profiling of seminomatous testicular germ cell tumors

Abstract

Abstract In depth Whole Transcriptome Analysis by RNA-Seq was used to compare the expression profile of testicular germ cell tumors with the histology of seminoma and normal testis. From this analysis we identified a large number of genes that showed differential expression with statistically high significance, (p<0.01, >2X FC). The list included genes related to stem cell pleuripotency (NANOG, POU5F1), proliferation (KRAS, CCND2), a number of non-coding RNAs (snoRNAs, miRNA precursors, XIST), and testicular cancer related genes (LDHB, AKAP4). From this list we identified a subset of genes for validation and further screening. We used the OpenArray® RT-qPCR platform to quantitatively screen up to 224 coding and non-coding genes using samples from different testicular germ cell tumors (seminoma and non-seminoma) and normal tissue. Results from these screening experiments will be presented. For research use only. Not for diagnostic procedures. Citation Format: Sunali Patel, Shirley Chu, Lovorka Degoricija, Kathy Y.
