Researchers from the group of Jop Kind developed a new technique called MAbID. This allows them to simultaneously study different mechanisms of gene regulation, which plays a major role in development and disease. MAbID offers new insights into how these mechanisms work together or against each other. The results were published in Nature Methods.

DNA is the most important carrier of genetic information. Each cell contains approximately two meters of DNA. To ensure that all this genetic material fits into the small cell nucleus, it must be tightly packed. The DNA is therefore wrapped around a special type of protein, a histone. The packages of DNA and histones are called chromatin.

Reading DNA

Chromatin not only ensures that all the DNA fits into the cell, it also determines which parts of the genetic material can be read by the cell. For example, a piece of DNA that is tightly wrapped around the histone is more difficult to read than a piece of DNA that is packed more loosely. Ultimately, the way in which chromatin is folded determines which parts of the genetic material are expressed and which parts are not. This pattern of gene expression differs per cell type. Different genes are active in a skin cell than in a liver cell, for example.

Changes in chromatin

The activity of genes is not always the same: a different pattern of genes may be active in one moment compared to another. That is because the structure of chromatin can change. For instance, changes can occur in the histones, which are called histone modifications. Certain proteins can also bind to the chromatin. Both processes influence the readability of the DNA and therefore the gene expression.

New technique

In recent years, various technologies have been developed to investigate the mechanisms of gene regulation. However, there was still a technique missing to allow researchers to simultaneously look at multiple mechanisms in one cell. The group of Jop Kind therefore designed a new technique: MAbID. With MAbID, researchers can simultaneously study multiple types of histone modifications and the proteins that bind to chromatin.

Working together

“With our new technique, we can see how the different mechanisms of gene expression are connected, for example how they work together or against each other. And the great thing is that we no longer need separate experiments for this, we can study everything at once in each individual cell. That makes the research much more efficient,” Silke Lochs, one of the researchers on the project, explains.


The technology can be widely applied. Robin van der Weide, another researcher on the project, says: “MAbID can help us answer fundamental scientific questions, for example about how gene regulation works during the development of humans or animals. But we can also use it for research into the development of diseases that can be caused by abnormalities in gene regulation, such as cancer.” The versatile new technology can therefore in the future provide important insights into both health and disease.
