The effect of the Rad51 controlled expression of DTA was evaluated following IP injections of Rad51-DTA plasmid in the case of IP tumors (receiving 6 doses of 100 μg plasmid over 15 days) or intratumoral injections to SC tumors (receiving 6 doses of 20 μg plasmid over 28 days). Here, RAD51 is linked to incontinentia pigmenti.
