doi: 10.3892/mmr.2019.10610

Figure Lengend Snippet: Rsf-1 expression in melanoma cell lines and Rsf-1 knockdown efficiency. (A) Western blotting and RT-qPCR analysis revealed the endogenous expression levels of Rsf-1 in three melanoma cell lines (MV3, M14 and A375). (B) Western blotting and RT-qPCR analysis demonstrated that Rsf-1 siRNA transfection significantly decreased Rsf-1 expression levels in MV3 and A375 cells, while Rsf-1 plasmid transfection upregulated the protein and mRNA expression of Rsf-1 in M14 cells. Data were presented as the mean ± standard deviation of at least three experiments. *P<0.05 vs. control. Rsf-1, remodeling and spacing factor 1; RT-qPCR, reverse transcription-quantitative polymerase chain reaction; siRNA, small interfering RNA.

Figure Lengend Snippet: Rsf-1 regulates melanoma cell viability and invasion. (A) An MTT assay (96-well plate) revealed that Rsf-1 depletion decreased the viability of MV3 and A375 cells; conversely, Rsf-1 overexpression increased M14 cell viability. (B) A colony formation assay (culture dish diameter, 6 cm) demonstrated that the colony number was reduced in MV3 and A375 cells transfected with Rsf-1 siRNA, while Rsf-1 overexpression promoted colony formation ability in M14 cells. (C) A Transwell invasion assay (24-well plate) revealed that the number of invading cells decreased following Rsf-1 depletion in MV3 and A375, and increased following Rsf-1 overexpression in M14 cells. Data were presented as the mean ± standard deviation of at least three experiments. *P<0.05 vs. control. Magnification, ×200. Rsf-1, remodeling and spacing factor 1; siRNA, small interfering RNA.

Figure Lengend Snippet: Rsf-1 regulates cell cycle progression of melanoma and expression of MMP2, cyclin E and p-IκB. (A) Cell cycle analysis revealed that Rsf-1 depletion increased the percentage of G1 phase cells and decreased that of S phase cells in MV3 and A375 cell groups; Rsf-1 overexpression in M14 cells exhibited opposing effects. (B) Western blotting demonstrated that Rsf-1 depletion decreased the levels of MMP2, cyclin E and p-IκB in MV3 and A375 cell lines. Rsf-1 overexpression upregulated expression of MMP2, cyclin E and p-IκB in M14 cells. Data were presented as the mean ± standard deviation of at least three experiments. *P<0.05 vs. control. MMP2, matrix metalloproteinase-2; p, phosphorylated; Rsf-1, remodeling and spacing factor 1; siRNA, small interfering RNA.

Figure Lengend Snippet: Rsf-1 regulates chemoresistance and the MMP of melanoma cells. (A) An MTT assay revealed that cell viability was decreased following Rsf-1 depletion in MV3 and A375 cells treated with cisplatin. Rsf-1 overexpression promoted cell viability in M14 cells treated with cisplatin. (B) Annexin V/propidium iodide analysis revealed that the percentage of apoptotic cells was significantly increased in Rsf-1-depleted MV3 and A375 cells compared with controls. Rsf-1 overexpression downregulated cisplatin-induced apoptosis in M14 cells. (C) Rsf-1 overexpression reduced MMP depolarization in M14 cells, while Rsf-1 depletion increased depolarization in MV3 and A375 cells treated with cisplatin. Data were presented as the mean ± standard deviation of at least three experiments. *P<0.05 vs. control.

Figure Lengend Snippet: Rsf-1 regulates Bcl-2 expression via NF-κB signaling. (A) Western blotting revealed that Bax expression levels increased, whereas cIAP1, cIAP2 and Bcl-2 expression decreased significantly following Rsf-1 depletion in MV3 and A375 cells. Rsf-1 overexpression in M14 cells exhibited opposing effects. (B) NF-κB inhibition significantly downregulated p-IκB and NF-κB p65 protein levels in M14 cells. NF-κB inhibition also eradicated the effects of Rsf-1 overexpression on Bcl-2 upregulation. Total IκB expression was markedly altered.
