Abstract: Expression level of numerous genes may be affected by environmental condition and lead to development of cryptorchidism. The most common congenital malformation in male is cryptorchidism. One major consequence of this anomaly is infertility due to undescended testis, to which an increased risk of testicular cancer is associated. Expression of total RNAs isolated from testicular biopsies were analysed with microarray. This was followed by subsequent bioinformatic analysis and RT-qPCR validation of many highlighted genes. Those analyses allowed me to identified more than two thousand genes that showed a differential expression between normal and cryptorchid subjects. Among these highlighted and validated genes, some can be either associated to testicular descent, to testicular cancer, or to specific cell types in testes. Differences in transcriptome due to cryptorchidism should give us clues to identify the genetic causes of this malformation.
