Abstract | BACKGROUND/AIM: MATERIALS AND METHODS: Cell viability was measured by flow cytometry. DNA condensation (apoptotic cell death), DNA damage, and DNA fragmentation ( DNA ladder) were assayed by DAPI staining, comet assay, and agarose gel electrophoresis, respectively. The expression of DNA damage and repair proteins was assayed by western blotting. RESULTS:
Maslinic acid decreased total cell viability and induced DNA condensation, damage, and fragmentation in HeLa cells. Furthermore, maslinic acid elevated the levels of p-ATMSer1981, p-ATRSer428, p53, p-p53Ser151, p-H2A.XSer139, BRCA1 and PARP at 30-40 μM. However, it decreased the levels of DNA-PK and MGMT. CONCLUSION:
Maslinic acid reduced the number of viable HeLa cells by inducing DNA damage and altering the expression of proteins involved in DNA damage and repair.
