Laboratory of Reproductive Biology

We study fertilization – sperm, eggs and their interaction and we develop new diagnostic tools for quality assessment and gamete selection for Centers of Assisted Reproduction.

Doc. RNDr. Kateřina Komrsková, Ph.D.

Our laboratory has extensive knowledge of assessing male reproductive parameters as markers of fertility disorders. We focus on studying the molecular mechanisms of reproduction and the nature of specific sperm proteins that play a role in sperm maturation, sperm-egg interaction and early embryo development. The area of our interest covers monitoring of sperm quality in patients with testicular cancer and  characterisation of sperm antibodies in infertile couples. Our goal is to apply the knowledge of basic research into clinical practice, in order to develop new diagnostic tools for sperm quality assessment and gamete selection for Centres of Assisted Reproduction.

Recently, we have been studying in detail characterization of dynamic rearrangement of cytoskeletal proteins and their partner proteins (IZUMO1, CD46, CD9, CD81, CD151 and integrins) involved in sperm-egg fusion. In addition, the acrosin inhibitor expression and crucial ubiquitin proteasomal complex during sperm maturation has been addressed. Epigenetic aberrations (selected histone modifications and DNA methylation) in spermatozoa, testicular tissues and early embryos after exposure to environmental pollutants have been studied and new related project are in progress. All the ongoing research is supported by several prestigious grants. The outcome of this research is being translated into new diagnostic tools for identification of sperm parameters and selection of good and bad sperm to be used in Centres of Assisted Reproduction. This translational research is supported by grants of the Technological Agency of the Czech Republic and the Agency of Ministry of Health. Two European and two Czech patents were submitted.

We have productive collaboration based on the knowledge of the detailed assessment of reproductive parameters, monitoring of transgenerational epigenetic inheritance, characterization of epigenetic aberration and microRNA deregulations, all tailored for specific areas of interest (medical conditions, lifestyle, environmental factors). In addition, we utilize, in collaboration with commercial subjects, our knowledge of hybridoma technology for the production of specific monoclonal antibodies with high affinity, and twelve prototypes for the detection of relevant molecules have been developed. Moreover, we have valuable collaboration based on transgenic mouse lines, property of our laboratory, serving as indispensable tool for in vivo experiments, specifically transgenic C57BL/6Acr3-EGFP mice expressing green protein (EGFP) in sperm acrosome, transgenic C57BL/6Su9DsRed2 mice expressing red fluorescent protein (RFP) in somatic cell mitochondria.
