Induction of cytogenetic adaptive response of mouse bone marrow cells to radiation by therapeutic doses of bleomycin sulfate and actinomycin D as assayed by the micronucleus test.

abstract：:Bone metastasis is an important cause of morbidity in advanced prostate cancer. Bisphosphonates are widely used for the treatment and prevention of osteoporosis, but recently have been observed to be effective in controlling prostate cancer metastasis. Since aminopeptidase N (AP-N) is known to be involved in the metas...
