  • Abstract:Background/aims:Periostin is upregulated in non-small cell lung cancer (NSCLC). This study was done to explore the function of periostin in the development of cisplatin (CDDP) resistance in NSCLC. Methods:The effects of overexpression or knockdown of periostin on CDDP sensitivity was examined in A549 cells. The involvement of signal transducer and activator of transcription 3 (Stat3) and Akt signaling in the action of periostin was checked. The in vivo effect of periostin silencing on CDDP susceptibility was determined in a mouse xenograft model. Results:Periostin was significantly upregulated in CDDP-resistant A549 cells, compared to parental controls. Overexpression of periostin rendered A549 cells more resistant to CDDP-induced apoptosis and enhanced Stat3 and Akt phosphorylation and survivin expression. Periostin-mediated protection against CDDP-induced apoptosis was compromised by downregulation of survivin. Furthermore, knockdown of periostin re-sensitized CDDP-resistant A549 cells to CDDP. After CDDP treatment, greater volume reduction was observed in periostin-silenced xenograft tumors than in control tumors, which was accompanied by reduced levels of phosphorylated Stat3 and survivin in periostin-depleted tumors. Conclusion:In conclusion, periostin promotes CDDP resistance in NSCLC cells largely through activation of Stat3 and Akt and upregulation of survivin and thus represents a promising target for overcoming CDDP resistance.
