Improvement in epigenetics research by discovery of a major technical error

An error in one in every of the foremost wide used methods in epigenetics, DIP-seq, will cause deceptive results, researchers at Linköping University, Sweden, have shown. This might have major significance within the research field, wherever massive knowledge and advanced methods of deoxyribonucleic acid analysis are used to study immense amounts of epigenetic information. The error may be corrected in previously collected DIP-seq information, which can result in new discoveries from previous studies of human epigenetics. In principle, each cell has the identical deoxyribonucleic acid sequence. However, completely different cell varieties use very different groups of genes. This implies that extra signals are needed to regulate that genes are utilized in every individual cell kind. One variety of such signals consists of chemical teams directly attached to the deoxyribonucleic acid sequence. These chemical modifications of the deoxyribonucleic acid sequence form part of what is ordinarily referred to as the epigenetic code. Epigenetic regulation of genes plays a very important role in traditional human development, however, is additionally related to several diseases, like cancer.

Researchers at Linköping University have now discovered a weakness in one of the most frequently used methods in epigenetic research, DNA immunoprecipitation sequencing (DIP-seq). Put simply, this method is based on picking out the parts of the DNA that carry a particular epigenetic signal. For this, the researchers use various antibodies that recognize a specific chemical structure and bind to it. The antibodies are subsequently sorted and the sequences of the DNA that they have bound to are determined. Nestor's group noticed that certain epigenetic marks always occurred in the same place, even in DNA that shouldn't contain those epigenetic marks at all.
