The control layer on top of DNA, called the epigenome, determines which genes are turned on, which are turned off, and how active they are. Like a recipe book, DNA contains all the information needed to build a living organism.
The epigenome acts like a chef, deciding which recipe to use, when to use it, and in what quantities. When the epigenetic system malfunctions, cells can grow out of control, leading to cancer.
Previously, scientists studied DNA epigenome and RNA epigenome separately. They believed that these two processes occurred independently, regulating different stages of gene expression.
However, new research by the ULB team demonstrates that DNA and RNA epigenetics work together closely, forming an extremely sophisticated gene control system.
Like a symphony orchestra, each epigenome plays an important role but all work together to create a complete piece of music.
The discovery of this gene control mechanism opens up promising new perspectives in cancer treatment. As cancer cells grow, their epigenetic system often becomes disturbed.
By better understanding how epigenetics work, scientists can develop drugs that target these weaknesses, helping to kill cancer cells without harming healthy cells.
Although more research is needed, the discovery marks an important step forward in the fight against cancer.
The discovery of new gene control mechanisms not only helps us better understand cancer, but also opens the door to more effective, more personalized treatments for each patient.
