A team led by Professor Stefan H. Stricker at LMU and Helmholtz Munich has demonstrated for the first time that the amount of ribosomal RNA directly regulates cell division, specialization, and stem cell properties. The findings, published in Science, introduce a new CRISPR-based method to control protein production in cells.
The Discovery
Researchers led by Professor Stefan H. Stricker at LMU's Biomedical Center and Helmholtz Munich have directly demonstrated that ribosomal RNA (rRNA) levels regulate key cellular processes. The study, published in Science, shows that rRNA amount determines whether a cell divides, specializes, or retains stem cell properties. This is the first direct evidence linking rRNA to such fundamental decisions.
The Method
The team developed a new CRISPR-based technique to control rRNA production in cells. By precisely modulating rRNA levels, they could influence cell fate decisions. The method allows researchers to experimentally manipulate protein production speed, providing a tool to study cellular regulation.
Implications
The findings open new avenues for understanding diseases where cell regulation goes awry, such as cancer. Controlling protein production could lead to novel therapeutic strategies. The study involved international collaborators and was funded by multiple German research organizations.
What's Next
The team plans to explore applications of the method in disease models. It remains unclear how quickly the technique can be translated into clinical therapies.
