Metabolism drives growth and division of cancer cells

 The metabolic status of the cell and its supply of nutrients is signaled, amongst other, by the O-linked N-acetylglucosamine (GlcNAc) transferase (OGT). This enzyme links GlcNAc (orange squares) as a mark to STAT5 at the OH groups of threonine 92 (T). Cytokine receptors activate the kinase JAK2, which phosphorylates STAT5 on tyrosine 694 (Y) (red circles).

The metabolic state of tumor cells contributes to signals that control the proliferation of tumor cells. Already the German biochemist and Nobel Prize laureate Otto H. Warburg observed in the 1920s that tumor cells radically change their metabolism. This process was termed "Warburg Effect", however neglected until recently by cancer research, but the latest results show it is indeed of fundamental importance for the development of aggressive tumors.

Researchers of LBI-CR raised a record breaking 1.8 Mio € of external funds in 2016

In 2016 keyresearchers of the LBI-CR succeeded in raising more funds for their research than ever before. We are proud to report an outstanding success rate of 60%, as of ten proposals we received funding for six projects totalling an overall volume of € 1.8 Mio. With the renewal of one SFB and the intitiation of a new one Richard Moriggl maintains outstanding financial support by the Austrian Science Fund (FWF).

Luisa Schmidt receives Best Abstract Award at LBG Health Sciences Meeting

For the third time the LBG Health Sciences Meeting awarded the best research contributions with a prize. In the category "Cancer Research" Luisa Schmidt of the research group Florian Grebien at the LBI-CR was selected with her research on "Acute Myeloide Leukemia with CEBPA Mutations is sensitive against Blockade of Menin-MLL Interaction". We congratulate Luisa to this fine success.

Quest for origin of Ewing Sarcoma successful

In order to develop better therapies against cancer, researchers are now faced with ever-increasing efforts. Since cancer is a complex disease affecting the entire organism, genetically modified mice play an important role in cancer research. Above all in rare cancers, clinically relevant animal models are essential to investigate the effect of new drugs. For this reason, researchers have tried for many years but failed to develop a suitable model for Ewing sarcoma.

Stress hormones accelerate obesity and diabetes upon aging

More than 600.000 people suffer from diabetes in Austria and every third person is not yet aware of that metabolic disease. Even a greater number of the population is seriously overweight, which underlies many age-related diseases including development of type II diabetes. Preventive medications and detailed understanding to avert these diseases are therefore an important health issue.
