Zoology

The Zoology division, led by  Prof. Dr. Achim Paululat and  PD Dr. Heiko Harten, researches the genetic and molecular causes of congenital organ defects. The team is particularly interested in genes that ensure cell function. One area of research focuses on intracellular membrane systems and human heart disease, which are ‘recreated’ and analysed in fruit flies. 

Translational biology - of men and flies

In the Zoology division, we study fruit flies (Drosophila melanogaster) to better understand hereditary diseases. Seventy percent of all human genes are also found in the genome of a fly. And although humans and flies are very different, at the cellular level, the genes of the fly function in exactly the same way as those of humans.

And flies, just like us, can have hereditary diseases that impair the function of the heart, the ‘kidneys’ or the sensory organs. Cardiac arrhythmia, lack of sperm motility or failure to eliminate toxins are problems that can affect flies just as much as humans. The Zoology division researches the genetic, molecular biological and cellular basis of tissue and organ development. In this way, we are attempting to bridge the gap between basic research and clinical application.

We have the most modern examination methods at our disposal

Whether human heart tissue or a fly's heart: today, we work with our electron microscopists to produce three-dimensional images of heart cells at the highest possible resolution. It is only thanks to such state-of-the-art methods that it has been possible, for example, to discover mitochondrial damage in TMEM43 heart patients and in flies carrying the same hereditary disease. Our mass spectrometric, molecular and imaging research on this ARVC Type 5 cardiomyopathy Drosophila model thus helps to understand diseases and develop long-term measures for alleviation or cure.

Teaming up with other research institutions

Modern research requires a very broad spectrum of methods and teamwork across disciplines and locations. In our DFG-funded research projects, we collaborate with colleagues from Kiel, Manchester, Münster, Marburg and Bielefeld, among others. We conduct our clinically relevant studies in cooperation with the Heart and Diabetes Centre in Bad Oeynhausen.

Short-eared owls and flocks of goldcrests: birdwatching excursion to Heligoland organised by the Zoology division

In October, the Zoology division held its annual excursion to Heligoland. The group discovered more than a hundred different species this year. Two short-eared owls and huge flocks of goldcrests caused particular excitement.

A schematic illustration of a fruit fly larva labeled “3rd larva”; arrows with the terms “heart chamber”, “aorta” and “intercardiac valves” point to the elongated green heart.

Fly heart research: Osnabrück zoologists decode the function of heart valves in insects

A study by Osnabrück biologists Prof. Dr. Achim Paululat and Dr. Christian Meyer shows: Heart valves play an important role in the circulatory system of fruit flies. The results were published in the prestigious journal “PLOS Genetics”.
