Fertile Considerations

Fertile miceDid you know that according to WHO, infertility affects up to 15% of reproductive-aged couples worldwide? In some cases, no cause can be found and there is no treatment available. This can be devastating news to couples who are trying to conceive. Dr Greg Anderson of the Department of Anatomy and Centre for Neuroendocrinology at the University of Otago School of Medical Sciences in Dunedin, New Zealand is working to improve and create new treatment strategies for infertility.

Dr Anderson’s research group focuses on studying how nutritional factors impact fertility and the mechanisms by which the newly discovered brain peptide, RFamide-related peptide-3 (RFRP-3, or gonadotrophin inhibitory hormone) regulates reproductive activity and anxiety in mammals. His group uses a combination of study methods involving transgenic animal models, single cell measurement techniques and visualisation of cell signalling in specific target neurons. They are specifically interested in the neural pathway that drives fertility, the GnRH neurons, and how these pathways sense the hormone leptin in order to respond to an animal’s nutritional state. They are also studying how RFRP-3 regulates GnRH and LH secretion in mammals.

Recently, Dr Anderson presented his work at the Neuroscience 2014 Annual Meeting in Washington DC. He shared his findings of using an Ozgene developed RFRP-Cre mouse to study the importance of RFRP-3 neurons in the hypothalamic control of fertility through estradiol. The aim of this study was to investigate whether RFRP-3 neurons mediate estradiol negative and positive feedback in female mice. The results highlight the importance of RFRP-3 neurons as key players in the hypothalamic control of fertility via estradiol.

Dr Anderson’s work is important in understanding the complexity of fertility and what impacts it. His work may someday help infertile couples around the world achieve their dream of becoming parents.

“I was impressed with the discussions with the Ozgene technical team, prior to us making a decision. Once the project started, regular updates made me feel like I knew what was going on at every step in the process. The resulted mouse model has made a major impact on our research, opening up several avenues that were not available to us previously.”

Who said a Lean year was a bad thing?

Frank’s blog – Wow. What a year it has been. 2014 was the most successful year in Ozgene’s history. Why? How? These are all very good questions so let me guide you through the year.

This year has been all about reducing timelines in order to deliver mice to our clients as fast as possible. We identified our minimum timeline that could be reached if there was no waste and everything worked the first time. We then set out to make it happen. We have already achieved over 30% improvement in our timelines in 2014, and we are not done yet!
