Epidemiological studies have suggested that regular intake of some non-steroidal anti-inflammatory drugs (NSAIDs) have a
preventative effect against several types of tumors including breast cancer in humans. This present study aims to investigate
the effect of both ibuprofen and aspirin on DNA damage using lymphocytes obtained from breast cancer patients and comparing
the result with lymphocytes from healthy females as a control. Lymphocytes are useful surrogates for cancer cells. Nanoparticles
(NPs) and bulk sizes were used in the Comet and micronucleus assays. 250ng/ml of ibuprofen (NPs and bulk) and 500ng/
ml of aspirin were used as non-toxic doses to treat the lymphocytes. Aspirin, both bulk and nano sizes, showed a significant
reduction in DNA damage in the Comet and micronucleus assays. However, the effect of aspirin nano (P???0.01) was more
significant compared to aspirin bulk (P???0.05). Ibuprofen, in contrast, showed a significant reduction in micronucleus (MNi)
frequency in the micronucleus assay with the nano form (P???0.001) being more significant than the bulk form (P???0.01), whilst
its preventative effect with the Comet assay was insignificant. These observations suggest that NPs have better penetration
through the nuclear membrane due to their smaller sizes compared to their bulk size. Aspirin was more effective than ibuprofen
in the reduction of DNA damage and MNi formation in the Comet and micronucleus assays. NPs were more effective than bulk
sizes. The results are consistent with the view that NSAIDs, particularly aspirin and ibuprofen, could have a promising role in
cancer treatment including breast cancer.
