ABSTRACT
Objective:
To investigate the effect of matrine on increasing the sensitivity of A549/DDP cells to cisplatin by regulating microRNAs.Methods:
Data mining was performed on a microarray dataset (accession ID GSE43249) from GEO database using bioinformatics analysis. Then microRNAs which related to the sensitivity of A549 cells to cisplatin were selected as candidate microRNAs. A549 and A549/DDP cells were cultured in vitro. The expression changes of candidate microRNAs were confirmed by qRT-PCR. The effect of matrine on the level of candidate microRNAs was also determined by qRT-PCR in A549/DDP cells. The level of microRNA-192 (miR-192) in A549/DDP cells was up-regulated by transfecting sequence of miR-192mimic. The CCK-8 assay was used to observe the effect of matrine and (or) miR-192 up-regulation on the sensitivity of A549/DDP cells to cisplatin.Results:
Data miningResults:
showed that there were 11 microRNAs with significant changes in A549/DDP cells compared with cisplatin-sensitive A549 cells (P < 0.05). The changes of miR-192 and miR-194 expression were confirmed in vitro. Compared with untreated A549/DDP cells, matrine treatment reduced the level of miR-192 in A549/DDP cells (P < 0.05). Matrine treatment increased the sensitivity of A549/DDP cells to cisplatin. Up-regulation of miR-192 could antagonize this effect and induce the resistance of A549 cells to cisplatin.Conclusion:
Matrine may increase the sensitivity of A549 cells to cisplatin by inhibiting miR-192.
