Researchers at the University of Virginia School of Medicine have discovered that as we age, our cells’ nuclear membranes become misshapen, which stops our genes from working properly.
Nuclear membranes become distorted with age
The DNA in all our cells is the same; however, the cells in our body show a great range of variation and function. How can this be when they have the same DNA? It all comes down to gene expression and which genes are turned off and which are turned on. For example, certain genes must be turned on in a cell for it to be a liver cell; those same genes need to be turned off for it to be a brain cell. If the correct genes are not turned off, problems occur.
