Transcriptionally silent RNA populations exist within mature human spermatozoa, and these messages are delivered to the oocyte at the time of fertlization. We are attempting to determine the role for these RNA in sperm. Our studies are examining potential applications in clinical fertility diagnostics as well as the re-examination of the male gamete's role in reproduction. more


Understanding the role of chromatin structure and how associations with the nuclear matrix, are involved in the expression of the protamine cluster is fundamental to understanding gene regulation and is a key element that will bring gene therapy from the bench to the bedside. more


We currently use NGS technology and a number of "home grown" in silico bioinformatics analysis methods to examine gene expression and chromatin structure. more
