Alterations affecting the mitochondrial genome and chromatin integrity of spermatozoa impair male reproductive potential. This study aimed to evaluate the impact of mitochondrial DNA (mtDNA) copy number alterations on sperm motility and on the molecular mechanism regulating the number of mtDNA copies, through analysis of mitochondrial transcription factor A (TFAM) gene expression. It also investigated...
Various microRNAs from the miR-371-3 and miR-302a–d clusters have recently been proposed as markers for testicular germ cell tumours. Upregulation of these miRNAs has been found in both the tissue and serum of testicular cancer patients, but they have never been studied in human seminal plasma. The aim of this study was, therefore, to assess the differences in the expression of miR-371-3 and miR-302a–d...
