Baylor College Scientist Presents Update on Osteogenesis Imperfecta


Dresden, 16.11.2018

Dr. med. Ingo Grafe, a German clinician scientist currently working with the group of Brendan Lee at the Department of Molecular and Human Genetics at Baylor College of Medicine in Houston, Texas, will give a talk on osteogenesis imperfecta on 3rd December at 3 pm in the lecture hall at house 19 (DINZ) in a joint symposium of the Center for Healthy Aging (UCGA) and the Center for Rare Diseases (UCSE) at UKD. He will give new insights into the therapy of the disease and will present novel therapeutic targets for its treatment both in adults and children. The research group of Prof. Brendan Lee is one of the most prestigious and productive genetic bone groups in the US and Dr. Grafe is looking forward to sharing his expertise with both clinicians and scientists here in Dresden.

All physicians, scientists, and students are welcome.

Strong bones and less fat

Strong bones and less fat – Scientists from Dresden and Leipzig identify novel molecular switch of bone and energy metabolism


Dresden, 09.11.2018

The formation of bone and fat is very much interdependent as both tissues originate from the same type of progenitor cells: mesenchymal stem cells. These either evolve into osteoblast, cells that build up bone mass, or into adipocytes, fat cells, respectively. Factors supporting the formation of fat tissue inhibit bone regeneration at the same time and thereby negatively impact bone quality.

A team of scientists from the Universities of Dresden, Leipzig and Ulm has now identified a novel protein controlling this interaction in a study recently published in Science Translational Medicine. CD90/Thy-1, as the protein is named, enhances bone regeneration, while concurrently inhibiting the accumulation of fat tissue. Mice lacking this protein have brittle bone and grow fatter. Furthermore, the scientists showed that both patients with osteoporosis and patients who are overweight exhibit lower serum levels of CD90/Thy-1 than healthy patients. Further investigations will likely reveal, whether this factor can be applied to improve bone quality in patients with overweight in future, or act as a marker for early diagnosis of bone loss.

Bone health is a crucial factor to assure quality of life


Dresden, 01.11.2018

A novel review of Tilman Rachner describes how adjuvant endocrine therapies of breast and prostate cancer impair bone health to reduce risk of fracture. Preservation of bone health still remains a long-term clinical challenge in patients with breast and prostate cancer. Dr. Rachner emphasizes: “Each patient receiving endocrine therapy should be stringently assessed for their individual fracture risk when therapy is initiated, and this risk should be reassessed in adequate intervals or whenever major changes to disease status or treatment occur.”

μBONE – Colonization and Interactions of Tumor Cells within the Bone Microenvironment


Dresden, 01.10.2018

A Germany-wide consortium of cancer and bone scientists started its work on studying the initial colonization of bone by tumor cells and the early interaction with bone cells. To obtain mechanistic insights into these questions, the consortium focusses on breast and prostate cancer. The µbone research alliance will tackle the knowledge gap on bone metastases and reveal innovative mechanistic concepts of bone-tumor interactions for subsequent studies to prevent or cure bone metastases.

New chair “Molecular Bone Biology” of the Medical Faculty Dresden


Dresden, 01.10.2018

Dr. scient. med. Martina Rauner commenced her new position as Professor for Molecular Bone Biology in October 2018. Achieving deeper insights into bone diseases is at the core of her research, which may ultimately lead to the discovery of new ways to treat bone diseases. Focus of her research lies on unraveling interactions of bone with hematopoietic cells including immune cells. Martina Rauner is a trained biotechnologist and due to her broad expertise in bone biology is also the Scientific Director of the Bone lab since 2014. As former chair of the ECTS Academy and New Investigator Committee of the ECTS, her ambition is further to inspire young researchers and to promote their scientific careers and encourage networking and engagement.
