RSF-1/hSNF2H Promotes the Proliferation and Migration of Adenoid Cystic Cancer Cells
摘要
The study analyzed the expression of remodeling and spacing factor-1 (RSF-1) and human sucrose nonfermenting protein 2 homologue (hSNF2H) in adenoid cystic carcinoma (ACC) of the salivary gland and their relationship with clinicopathological factors. Immunohistochemical methods were used to detect the expression of RSF-1 and hSNF2H in ACC. Immunofluorescence assay was used to verify the relationship between the expression of RSF-1 and hSNF2H. The effects of RSF-1 and hSNF2H on the proliferation and migration of ACC cells were evaluated by using colony formation assay and wound healing assay. Significant differences in the expression of RSF-1 and hSNF2H in various tissue types of ACC were revealed by immunohistochemical methods. The immunofluorescence experiment results showed that RSF-1 and hSNF2H were co-localized in the nucleus. Knockout of RSF1 or hSNF2H suppressed proliferation and migration of ACC cells. In addition, simultaneous knockout of RSF1 and hSNF2H further reduced viability of ACC cells and prevented cell metastasis. The expression of RSF-1 and hSNF2H was high in ACC, which was closely related to tumor tissue type. RSF-1 and hSNF2H can promote proliferation and migration of ACC cells.
