Have you ever wondered what role does the nucleolus content of the cell plays? Until now, what we know about the nucleolus is that it is the content of the cell in the center of the nucleus when the cell is in the interphase. However, recently scientists have worked out that the nucleolus plays an essential role in the aging process.

The background of the research story begins in this way. Once upon a time, there was a mutant worm in one of the related experiments. The researchers observed that it lived for about forty-six days. It is in lieu of the survival period of the ordinary oldest worm. The average survival period of the regular oldest worm is approximately twenty-two years.

The researchers found out that a mutated gene was responsible for the lengthening of the survival period of the worm. It gave rise to a breakthrough for the scientists in the aging study. It was observed to be monitored by the metabolic processes. Later, as the researchers carried ahead with these studies, they found that the connecting link was the nucleolus.

The nucleolus is easily observed under the microscope. Take any cell. Trace out the location of the nucleus in that cell. Then search for a little, dark blob inside the core. That’s it. The dark and little blob is what you call the nucleolus. The nucleolus is a part of the nucleus of every cell of every individual body. All the animal cells, including the plants and the yeast cells, have nucleolus within it. The nucleolus has contributed to our understanding of how our cell functions.

Adam Antebi says, “We think the nucleolus plays an important role in regulating the lifespan of animals.” Adam Antebi is a cellular biologist at the Max Planck Institute for Biology of Ageing in Germany. He is also the author of the new review published in ‘Trends in the Cell Biology.’ The further study focuses on the new ways that the researchers have with the role of the nucleolus, especially in aging.
