“Cancer Driver” STAT3 reduces metastasis in prostate cancer

A gene that is responsible for cancer growth plays a totally unexpected role in prostate cancer. The gene Stat3 is controlled by the immune modulator interleukin 6 and normally supports the growth of cancer cells. The international research team led by Prof. Lukas Kenner of the Ludwig Boltzmann Institute for Cancer Research (LBI-CR) discovered a missing link for an essential role of Stat3 and IL-6 signalling in prostate cancer progression.

Inhibition of an epigenetic complex reveals a new target in leukemia.

10 % of patients with acute myeloid leukemia (AML), a common form of blood cancer in adults, express a shortened form of the transcription factor C/EBPa that lacks a significant portion of the N-terminus of the protein. This short, mutant protein can induce leukemia development by preventing normal myeloid differentiation of blood cells. Through the investigation of specific interaction partners of the leukemia-associated, truncated variant of C/EBPa, the research group of Giulio Superti-Furga, Scientific Director at CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, has gained new mechanistic insights into the molecular details of oncogenic transformation by C/EBPa mutant proteins. Florian Grebien, postdoctoral fellow in Superti-Furga´s team and since 2014 group leader at the Ludwig Boltzmann Institute for Cancer Research, found that the short, leukemic C/EBPa mutant can exert its oncogenic functions through a selective interaction with Wdr5, a critical constituent of histone-methyltransferase complexes that promote gene activation. 

Breast cancer cells form metastases – new responsible gene is identified

A particular human gene variant makes breast cancer cells more aggressive. Not only are these more resistant to chemotherapy but also leave the primary tumour and establish themselves in other parts of the body in the form of metastases. An international group of researchers led by William Tse at James Graham Brown Cancer Center,University of Louisville, in cooperation with Lukas Kenner from the LBI-CR has now identified a gene, AF1q, as being substantially responsible for this and recognized it as a possible starting point for more accurate diagnosis and potential targeted therapeutic approaches.

Highly efficient protein production system introduced by researchers from LBI-CR

Recombinant protein production remains a central component of many biotechnological projects. As mammalian proteins frequently require extensive post-translational modification, mammalian cells are often used for recombinant protein production instead of yeast and bacteria. Intuitively, a protein will be best expressed in its native cell type under physiological conditions, where a multitude of
molecular systems work together for efficient production and quality control at various stages, including synthesis and folding, post-translational modifications and subcellular targeting. However, as mammalian cell culture is costly and establisment of efficiently producing cell lines can be a lengthy procedure, productivity is an important determinant.

LBI-CR participates in successful bid for European Training Network

The European Research Initiative of ALK-related malignancies (ERIA) forms the core of a successful proposal for a European Training  Network (ETN). Suzanne Turner of the University of Cambridge, Lukas Kenner (LBI-CR) and Olaf Merkel (Medical University Vienna) formed a consortium around some of the leading researchers focussing in malignancies driven by the oncogene ALK to facilitate the development of less-toxic and more efficacious therapies. The consortium developed a competitive training programme for twelve PhD students, which is complemented by an array of companies.

Jan Pencik receives "Young Investigator Award" of the prestigious Charles Rodolphe Brupbacher Foundation

Klaus W. Grätz (Decan of Medical Fakulty), Georg Umbricht (Stiftungsrat), Michael Kiessling, Hella A. Bolck, Jan Pencik, Phil F. Cheng, Christian M. Schürch, Markus G. Manz (Director Klinik für Hämatologie and Scientific Organisor)

The Charles Rodolphe Brupbacher Foundation bestowed recently their biennial prize to five young investigators, who contributed to their Scientific Symposium 2015. Jan Pencik received one of these awards for his research on "Aberrant STAT3-ARF signaling targets distinct subgroups of lethal prostate cancer".
