Bits of DNA from mitochondria can skip surprisingly fast into our genome and may reduce lifespan M ost of us remember two things from high school biology: that mitochondria are the powerhouses of ...
A simple prototype cell sorter has grown over time to incorporate technological advances that make it an even more indispensable tool for understanding biology and disease states ...
Smaller nucleoli slow aging, acting as a "mortality timer," while larger nucleoli lead to cell death by destabilizing rDNA. The secret to cellular youth may lie in maintaining a small nucleolus—a ...
This is possible because of careful regulation within the nucleus of each cell and involves thousands of regulatory proteins that localize to precise places in the nucleus. Because the nucleus is ...
