Primary study of the inhibitive effect of naphthalene acetic acid on K562 cell proliferation / 西安交通大学学报(医学版)

ABSTRACT

Objective To explore the effect of naphthalene acetic acid(NAA) on animal cells. Methods K562 cells were treated in vitro with different doses of NAA (0, 50 and 100?mol/L). The cell proliferation, cell cycle, cell division index and apoptosis was observed by means of MTT, cell enumeration, and flow cytometry. The sister chromatid exchange (SCE) and micronucleus were tested. Results The proliferation of K562 cell was inhibited by NAA compared with that of the controls; the cell cycle was arrested at G1, and the cell division index reduced; apoptosis cells increased lightly in NAA experiments; the frequency of SCE and micronuclear formation were increased by NAA treatment. Conclusion NAA has antiproliferative activities on K562 cell.
