DNA methylation patterns differ dramatically between healthy and diseased tissue and thereby can serve as biomarkers, opening a window into earlier detection of disease. In a special issue of the journal Disease Markers published in February 2007, ten articles explore the details and challenges of cancer epigenetics.
Writing in the editorial, Guest Editor Martin Widschwendter (Institute for Women’s Health, University College London) emphasizes that, “The concept of early detection of tumours before they spread and become incurable, represents one of the most important challenges in reducing the impact of the growing burden of cancer worldwide…Altered patterns of DNA methylation can be detected with high sensitivity, potentially providing us with diagnostic, prognostic and predictive information, and can be reversed by appropriate drug treatment. These possibilities make cancer epigenetics a most exciting field of current translational research.”
Four articles document different epigenetic alterations in lung, prostate, ovarian and colorectal cancer. The observation of abnormal methylation in the RASSF1A gene in a broad spectrum of tumors is reviewed by Luke B. Hesson, Wendy N.Cooper and Farida Latif. Heidi Fiegl and Karim Elmasry review how DNA-methylation can form the basis for diagnostics and therapeutic monitors.
Epigenetic silencing of the MGMT gene encoding a DNA repair enzyme was recently found to be of predictive value in a randomised clinical trial for newly diagnosed glioblastoma, reviewed by Peter Hau, Roger Stupp and Monika E. Hegi. The possibility of using epigenetic changes in normal tissue to predict an individuals risk of developing cancer is reviewed by Hengmi Cui.
Biostatisticians Todd A. Alonzo and Kimberly D. Siegmund provide an excellent review about various statistical approaches to analysis of the wealth of information gained by DNA methylation studies.
Finally, Craig A. Cooney discusses the recent emergence of “epigenetic epidemiology” where the causes of DNA methylations might be understood and used to direct epigenetics toward improved health and longevity.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
