Abstract:

AIM: To study the effect of naringin on the growth of non-small cell lung carcinoma cells (NSCLC) and its mechanism. METHODS: SRB method was employed to investigate the inhibitory effect of naringin on the growth of non-small cell lung carcinoma cell lines. Western blot was used to detect the p70S6K expression. The plasmid encoding full length p70S6K was transfected to over-express p70S6K. The small-interfering RNA was used to knockdown p70S6K expression. RESULTS:Naringin inhibited the growth of NSCLC cells, and down-regulated the expression of p70S6K. The over-expression of p70S6K partially abrogated the inhibitory effect of naringin, while knockdown of p70S6K enhanced the effect of naringin. CONCLUSION: Naringin can down-regulate the p70S6K to inhibit the growth of NSCLC cells.

Key words: p70S6K, naringin, non-small cell lung carcinoma cells
