I've started to study the role of miRNA in cancer. Wikipedia says:
Just as miRNA is involved in the normal functioning of eukaryotic cells, so has dysregulation of miRNA been associated with disease.
The first human disease known to be associated with miRNA deregulation was chronic lymphocytic leukemia.
1- What is the difference between dysregulation and deregulation?
2- How are these concepts related to RNA degradation?
