ABSTRACT

Objective To investigate the inhibitory effect of celebrex on non-small cell lung cancer and its mechanisms.Methods the inhibitory effect of celebrex on NSCLC were detected by MTT Flow cytometry, electron microscope were used for evaluation of apoptosis and cell cycle block. The expression of P27 KIP1, XIAP were detected by reverse transcription-polymerase chain reaction.Results 1. celebrex inhibited cell survival of NSCLC in a time-dependent and concentration-depended manner, and the effect of celebrex were more pronounced in NCI-H520 than in A549.2.Flow cytometry show that celebrex induced a G0/G1 cell arrest in NSCLC. 3. The result of these apoptosis test' indicate that celebrex caused apoptosis in concentration-depended manner. 4.celebrex increased the expression of P27 KIP1,and decreased the expression of XIAP.Conclusions celebrex inhibited cell survival of NSCLC.Its mechanisms involved in cell cycle arrest and apoptosis.
