Objectives

To identify the association of fibronectin (FN) extra domain A (EDA) with the progression of salivary adenoid cystic carcinoma (SACC). Accordingly, the exclusion of EDA exon through the CRISPR/Cas9 system was investigated as the rescue for such pro-oncogenic splicing.

Materials and methods

SACC-83 cells were transiently transfected with plasmids containing recombinant EDA, and the cellular growth and motility were then accessed in vitro. Epithelial-mesenchymal transition (EMT) was investigated with immunohistochemistry, Western blot, and real-time PCR analysis. SACC tissues from 81 patients were used to access the associations between EDA+FN and clinical-pathological parameters. CRISPR/Cas9 plasmids containing sgRNA were designed and co-transfected into SACC-83 cells; the effects of EDA knockout on cellular growth and motility were then accessed.

Results

The recombinant EDA exhibited little effect on the proliferation of SACC cells, but significantly promoted the migration and invasion of the cells (P < 0.05), accompanied with upregulated EMT (P < 0.05); consistently, the expression of EDA+FN was positively associated with the metastasis, nerve invasion and recurrence of SACC (P < 0.05). Furthermore, the EDA knockout from the FN gene in most SACC cells resulted in a decrease in cell motility and invasion, as well as prolonged population doubling time, compared with untreated SACC-83 cells (P < 0.05).

Conclusion

The EDA domain significantly promoted the motility of SACC cells, and positively associated with the tumor progression in patients with SACC. Thus, it is a potential risk factor and also a therapeutic target for SACC. The CRISPR/Cas9 system may control a pro-oncogenic splicing process through the exclusion of EDA exon from the FN gene, leading to inhibition of motility, invasion and proliferation of cancer cells."xsd:string
