Author Correction: High FMNL3 expression promotes nasopharyngeal carcinoma cell metastasis: role in TGF-β1-induced epithelia-to-mesenchymal transition
Scientific Reports(2022)
Abstract
Formin-like 3 (FMNL3) plays a crucial role in cytoskeletal mediation and is potentially a biomarker for cell migration; however, its role in cancer metastasis remains unknown. In this study, we found elevated FMNL3 protein expression in clinical nasopharyngeal carcinoma (NPC) tissues. FMNL3 expression positively correlated to the clinical stage, T (tumour), N (lymph node metastasis) and M (distant metastasis) classification of NPC patients. Moreover, FMNL3 positively correlated to Vimentin expression and negatively correlated to E-cadherin expression in clinical NPC samples. In vitro experiments showed that FMNL3 expression was inversely related to NPC cell differentiation status. Overexpression of FMNL3 led to epithelial-to-mesenchymal transition (EMT) in well differentiated CNE1 cells. TGF-β1-treated poorly differentiated CNE2 cells showed changes in EMT accompanied by enhanced FMNL3 expression and cell migration. On the contrary, knockdown of FMNL3 partially attenuated the TGF-β1-promoted CNE2 cell migration, together with associated changes in EMT markers. Finally, knockdown of FMNL3 also weakened EMT in tumours in xenographs. Our study indicates for the first time that TGF-β1/FMNL3 signalling may be a novel mechanism mediating EMT in NPC, which is closely associated with NPC metastasis.
