... About 41% of the US population is expected to be diagnosed with cancer during their lifetime. In 2009, an estimated 562,340 people died from cancer-related causes. Obesity, lack of physical activity, and poor diet may account for about one-third of these deaths. What is cancer? Cancer is a group of ...

Cancer epigenetics
Cancer epigenetics is the study of epigenetic modifications to the genome of cancer cells that do not involve a change in the nucleotide sequence. Epigenetic alterations are as important as genetic mutations in a cell’s transformation to cancer, and their manipulation holds great promise for cancer prevention, detection, and therapy. In different types of cancer, a variety of epigenetic mechanisms can be perturbed, such as silencing of tumor suppressor genes and activation of oncogenes by altered CpG island methylation patterns, histone modifications, and dysregulation of DNA binding proteins. Several medications which have epigenetic impact are now used in several of these diseases.
