Description
In humans, the most common sex chromosomal disorder is Klinefelter syndrome (KS), caused by the presence of one or more extra X-chromosomes. The KS patients display a diverse adult phenotype with increased height, gynaecomastia, and hypergonadotropic hypogonadism as the most common symptoms. Men with KS are almost always infertile due to testicular degeneration, which accelerates during puberty. Very few studies investigated the global gene expression analysis of adult KS testes and, more importantly, which cell types the differentially expressed transcripts originate from. Transcriptome analysis by RNA sequencing of fixed and paraffin embedded testes originating from 3 adult KS samples and 3 adult cellularity-matched controls revealed 236 differentially expressed transcripts in the adult KS testis. To examine the cellular origin of the differentially expressed transcripts, transcriptome profiling was also carried out on 4 testes with Sertoli Cell-Only and 4 testes with full spermatogenesis. Also, pre-pubertal KS and controls were RNA-sequenced. Overall design: Includes a total of 22 testis samples. 3 adult Klinefelter, 3 Klinefelter-like, 4 Sertoli Cell-Only, 4 with full spermatogenesi, 4 pre-pubertal Klinefelter and 4 pre-pubertal controls
