Abstract Purpose Capicua homolog protein (CIC) played a broad role in the development of cancer in humans, however, its role in the progression of gastric cancer (GC) specifically has been unclear. This study aimed to explore the expression of CIC and its potential clinical value in patients with GC. Methods The CIC levels in GC tissues and cell lines were examined by quantitative real-time polymerase chain reaction (qRT-PCR). And the in-vitro effects of CIC expression in MGC-803 cells on their proliferation, invasion, and the progression of epithelial-mesenchymal transition were assessed by CCK-8 assays, Matrigel-invasion analysis, qRT-PCR and Western blot assays, separately. In addition, the effects of downregulation of CIC on the activation of PI3K/AKT signaling pathway were measured using Western-blot analysis. Results The results showed CIC levels were lower in GC tissues and GC cell lines, and these lower CIC levels were correlated with tumor differentiation, Helicobacter pylori infection, TNM stage, and patient survival. In addition, CIC overexpression could promote cell proliferation, invasion, and progression of epithelial-mesenchymal transition in MGC-803 cells. Notably, exotic expression of CIC inactivated the phosphoinositide 3-kinase/protein kinase B signaling pathway. Conclusions In conclusion, our finding suggested CIC could serve as a potential diagnostic and prognostic biomarker and a probable therapy target for GC.

Abstract Background The metastasis of oral cancer is one of the main causes of death. However, the mechanisms underlying oral cancer metastasis have not been completely elucidated. Fermitin family member 1 (FERMT1) plays an -oncogene role in many cancers; however, the role of FERMT1 in oral squamous cell cancer (OSCC) remains unclear. Methods In this study, OSCC cells were treated with 5 ng/ml recombinant human Transforming growth factor-β1 (TGF-β1) protein. FERMT1 expression was measured in OSCC cell lines by RT-qPCR and western blotting. The effect of FERMT1 knockdown on the migration and invasion of OSCC cells was evaluated by Transwell assay. The epithelial-mesenchymal transition (EMT) and PI3K/AKT signaling pathway-related mRNA expression and protein levels were assessed by RT-qPCR and western blotting. Results We found that FERMT1 expression was elevated in TGF-β1-induced OSCC cell lines, and knockdown of FERMT1 inhibited the migration and invasion in TGF-β1-induced OSCC cells. FERMT1 silencing inhibited vimentin, N-cadherin, matrix metalloproteinase 9 (MMP-9) expression and promoted E-cadherin expression, suggesting that FERMT1 silencing inhibited EMT in TGF-β1-induced OSCC cells. Furthermore, FERMT1 silencing inactivated the PI3K/AKT signaling pathway in TGF-β1-induced OSCC cells. Activation of the PI3K/AKT signaling pathway reversed the effect of FERMT1 silencing on OSCC cell migration, invasion, and EMT. Conclusions FERMT1 silencing inhibits the migration, invasion, and EMT of OSCC cells via inactivation of the PI3K/AKT signaling pathway, suggesting that FERMT1 is a novel and potential therapeutic target for anti-metastatic strategies for OSCC.
