Scientists Discover Unique Mechanism for Sugar Control in the Body 0 15

Researchers from the Walter and Eliza Hall Institute of Medical Research in Australia have made an important discovery. They found that a unique protein called ubiquitin can directly "tag" sugar reserves known as glycogen and initiate their breakdown, effectively lowering glucose levels. These sensational results were published in the prestigious scientific journal Nature.

For a long time, it was believed that glycogen metabolism, the main form of sugar storage in the body, was already fully understood and regulated solely by known biochemical processes. However, the new study has radically changed this perception. It revealed a completely different, alternative mechanism that provides the body with remarkable flexibility in managing energy reserves.

At the center of this new mechanism is ubiquitin—a protein that was previously known for its ability to "mark" damaged or excess molecules for subsequent destruction. Scientists have proven for the first time that ubiquitin can bind not only to proteins but also directly to carbohydrates, particularly glycogen. This opens up entirely new horizons in understanding its functions.

During experiments on laboratory mice, it was observed that under conditions of starvation, when the body is in acute need of energy, glycogen levels significantly drop. At the same time, the number of ubiquitin "tags" on glycogen, on the contrary, increases. This compellingly indicates the direct role of this mechanism in activating the breakdown of sugar reserves. Further research has only confirmed that the intensification of this process inevitably leads to a decrease in glycogen content in cellular structures.

The authors of the study emphasize that this discovery paves the way for targeted intervention in the process of sugar accumulation in the body. This breakthrough knowledge could be critically important for developing new treatment methods for various diseases related to carbohydrate metabolism disorders. These include both rare glycogen storage pathologies and much more common ailments such as diabetes, obesity, as well as serious liver and cardiovascular diseases.

Scientists particularly note that existing market drugs, such as "Ozempic," affect sugar levels only indirectly, through complex hormonal pathways. However, the new, revolutionary approach potentially offers the opportunity to act directly on the root cause of glucose accumulation—the glycogen itself. This opens up entirely new prospects in the fight against metabolic disorders.
