Defects in the packaging of genetic material in malignant brain tumors

Glioblastomas are regarded as particularly aggressive brain tumors. In children with glioblastoma, Heidelberg scientists have now discovered genetic alterations that affect the function of DNA packaging proteins known as histones. In a cell, histones serve as coils around which the DNA wraps. At the same time, histones regulate gene activity. Mutations in histone genes have never before been tied to a disease. The group comprising scientists of…

Histone acetyltransferases HATs and their antagonists the histone deacetylases are important enzymes in epigenetic gene regulation. Scientists discovered new HAT inhibitors that are now being investigated for their potential as anti-cancer drugs.

Single molecules under the laser: How the genetic material is unwrapped

The genetic material found in cells is not in its free state, but is bound to large protein complexes and tightly wrapped. To activate genes that could well play a role in carcinogenesis, the genetic material first needs to be unwrapped and made accessible to other cell components. Using a new biophysical method called single molecule spectroscopy, scientists from the “Biophysics of Macromolecules” division at the German Cancer Research Centre…

Genes and epigenetic mechanisms

The different cell types in a multicellular organism contain the same genome but differ from each other dramatically in both function and structure nerve cells kidney cells etc.. The differentiation of the cells is linked to the identity of their precursors. This then raises the question If the cells destiny is not encoded in the DNA how do they know what to become? The new director of the Max Planck Institute of Immunobiology in Freiburg…

EU supports biophysicists from Ulm to elucidate the structure of chromatin

Human DNA consists of three billion base pairs, which corresponds to a total length of approximately two metres. DNA must be compressed 200,000-fold in order to fit into the tiny nuclei of mammalian cells. The thread-like complex of DNA and proteins is called chromatin. Although chromatin has been widely studied, relatively little is yet known about the spatial and temporal organisation of chromatin in interphase cells.

Neuroblastoma can spread relentlessly or shrink spontaneously. Scientists from the Hopp Children’s Cancer Center Heidelberg (KiTZ), the German Cancer Research Center (DKFZ), the University of Heidelberg and the National Center for Tumor Diseases (NCT) Heidelberg have shown that some malignant neuroblastomas employ a trick to avoid cell death: they use a special mechanism to lengthen the telomeres at the end of their chromosomes.
