Abstract:

Objective

To screen microRNA(miRNA) related to the cell invasion and metastasis in salivary adenoid cystic carcinoma (SACC) cell lines and investigate the effect of miR-181a in the cell invasion and migration in SACC.

Methods

A paired SACC cell lines(SACC-LM/SACC-83) with different cell invasive and migrative ability were chosen. MiRNA array was performed to analyze the different expression of miRNAs in the paired SACC cell lines and identify miRNAs related to the cell invasion and metastasis. Then SACC-LM and SACC-83 were transfected with miR-181a mimics and miR-181a LNA respectively. Wound healing assay and transwell assay were used to observe the changes of the cell migration and invasion ability after transfection. Data were analyzed using the Statistical Package for the Social Science (SPSS), Version 17.0. For all statistical analyses, P <0.05 was considered statistically significant.

Results

MiRNA array showed that the expression of miR-181a in SACC-LM cells was lower than SACC-83 cells. Wound healing assay and transwell assay showed that ectopic transfection of the miR-181a mimics into the SACC-LM cells led to inhibition in the cell invasion and migration (t=-5.235,P <0.05). When the SACC-83 cells were treated with miR-181a LNA, an improvement in the cell invasive and migrative ability was observed (t=7.713,P <0.05).

Conclusions

There are various miRNAs expressing differently in SACC cell lines with divergent invasive and migrative ability. Underexpression of miR-181a could enhance the cell invasive and migrative ability of SACC cells.
