Abstract
Esophageal squamous cell carcinoma (ESCC) is prone to metastasis and is a leading cause of mortality. The cytoskeleton is closely related to cell morphology and movement; however, little research has been conducted on ESCC metastasis. In this study, we found that the anchoring filament protein ladinin 1 (LAD1) specifically binds to LINC01305 for co-regulating the level of modulating cortactin proteins (CTTN) and neuronal Wiskott-Aldrich syndrome protein (N-WASP) phosphorylation, which mediates cytoskeletal reorganization and affects the metastasis of ESCC cells. Additionally, LINC01305 and LAD1 jointly promoted the epithelial-mesenchymal transition (EMT) process by activating the phosphoinositide-3-kinase-protein kinase B (PI3K/AKT) signaling pathway. Moreover, LINC01305 and LAD1 were related to the late clinical stage and lymph node metastasis of ESCC. Our study demonstrated that LINC01305 and LAD1 are major determinants of ESCC dissemination and revealed a novel molecular mechanism of cytoskeletal reorganization that controls ESCC metastasis.
