Putting the squeeze on obesity
What determines how much fat is stored on our bodies? That’s a question many people would like the answer to. Professor Herbert Herzog, from Sydney’s Garvan Institute of Medical Research, along with several of his colleagues, has set out to find some answers.
For over 25 years, Professor Herzog has been committed to neurobiology research. His focus has been on determining the processes that can lead to the development of obesity, anorexia and type 2 diabetes. Dr Herzog has used transgenic and knockout mouse models to investigate how the body clock regulates fat production, how natural gut hormones could be used to treat obesity, how certain molecules can turn appetite on or off, and the link between stress and obesity, just to name a few.
In his most recent research, featuring a mouse model generated by Ozgene, Dr Herzog focused on stress and diet induced fat gain. Neuropeptide Y (NPY) has been extensively studied and is known to play a critical role in energy homeostasis and stress-coping. Dr Herzog and his colleagues set out to investigate the specific effects of catecholaminergic NPY on energy homeostasis along with the critical role of the catecholaminergic system in maintaining homeostasis during stress. The results showed that catecholaminergic NPY activity has significant impact on body weight and adiposity under both an obesogenic diet and stressful conditions.
The scientific publication on this study is featured in the publications below.

Frank's blog - Absolutely f…ing awesome!
Pardon my English but that was my email to the Ozgene team this morning when they told me about the latest results. We are not quite ready to launch our new aptly named goGermline technology yet. I, however, just can’t quell my enthusiasm, so here it goes ....
