Fasudil, an inhibitor of Rho kinase, is known to suppress tumorigenicity and cancer metastasis. However, the underlying molecular mechanisms of how fasudil suppresses cell metastasis have not been fully elucidated. The purpose of this study was to determine the effects of fasudil on migration and cancer growth and to evaluate Rho kinase activity in the 95-D lung carcinoma cell line. The cytotoxic effect of drugs on 95-D cells was measured by the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Treatment with fasudil inhibited the growth of 95-D cells in a dose-dependent manner, and the IC50 of fasudil was approximately 0.79 mg/ml (95% confidence limits (CL): 0.58-1.11 mg/ml). The total amounts of active MMP2 and MMP9 per microgram of protein when treated with 0.75 mg/ml fasudil and using the gelatinase assay were decreased compared with the control group by about 22.7% (P<0.05) and 65.9% (P<0.01) respectively. Although ABCC1, ABCC3, ABCA3, and ABCC5 were over-expressed at the mRNA level, ABCE1 was the only transporter responsible for resistance in this study. We also found that myosin phosphatase targeting subunit 1 (MYPT1) phosphorylation at Thr-696, which provided direct evidence of Rho kinase activity, was reduced by 29.4% in response to fasudil compared with the control group (P<0.05). Taken together, our findings show that fasudil prevents cancer metastasis by inhibiting the Rho/Rho kinase pathway and that the ABCE1 gene was involved in the migration of 95-D cells.

Osteosarcoma (OS) is the most common primary malignant bone cancer in children and adolescents. Long non-coding RNAs (lncRNAs) have been shown to play significant role in various cancers, including OS. In a previous study, we have reported that a novel antisense lncRNA FOXF1-AS1, also known as FENDRR, could sensitize doxorubicin-resistance of OS cells through down-regulating ABCB1 and ABCC1. Here in, the critical role of FOXF1-AS1 in regulating OS progression was further investigated. Firstly, we found that FOXF1-AS1 and its antisense transcript FOXF1 expression were positively up-regulated in OS tissues and cell lines and correlated with poor prognosis of OS patients. Besides, FOXF1-AS1 as well as FOXF1 silencing significantly inhibited cell proliferation, migration, invasion of OS cells and tumor growth both in vitro and vivo through decreasing the expression of MMP2 and MMP9, whereas enhanced expression of FOXF1-AS1 had the opposite effects. In addition, mechanistically, both of FOXF1-AS1 and FOXF1 could regulate the expression of MMP2 and MMP9 at mRNA and protein levels, whereas FOXF1-AS1 could influence the FOXF1expression but FOXF1 did not have the same effect on FOXF1-AS1. Rescue assay further showed that FOXF1-AS1 overexpression efficiently reversed the knockdown of MMP2 and MMP9 expression induced by si-FOXF1. Thus, we concluded that FOXF1-AS1 may promote migration and invasion of OS cells through the FOXF1/MMP-2/-9 pathway. Taken together, these findings demonstrated the underlying mechanism of FOXF1-AS1 in the regulation of OS progression and provide a novel potential target in the OS therapy.
