Retinoblastoma: Magnetic Isotope Effects Might Make a Difference in the Current Anti-Cancer Research Strategy.

Human retinoblastoma cells were proven to possess some very unusual DNApolβ species. Being 23.5 kDa monomers, which itself is not common for the DNApolβ superfamily members, these chromatin associated proteins manifests most of the DNApolβ-specifc functional peculiarities making them legitimate targets for DNA repair cytostatic inhibitors.
