RNR (Ribonucleotide Reductase) is an enzyme that plays a crucial role in the synthesis of DNA. It is responsible for converting ribonucleotides into deoxyribonucleotides, which are the building blocks of DNA.
In cancer, RNR is often overexpressed, which can contribute to the rapid growth and proliferation of cancer cells. This is because cancer cells require a constant supply of DNA building blocks to support their rapid division.
Research has shown that inhibiting RNR can be an effective way to slow down or stop the growth of cancer cells.
