Abstract
ABSTRACT Esophageal squamous cell carcinoma (ESCC), a major form of esophageal cancer, is a serious threat to human health. This study was conducted to investigate the pathogenesis of ESCC and find effective therapies to improve it. Protein expression of transfected plasmids was detected by RT-qPCR and western blot. Co-immunoprecipitation assay was performed to verify the binding of LETM1 and KIF14. CCK-8, wound healing and transwell assays were used to assess the proliferation, invasion and migration of ESCC cells. Finally, the angiogenesis was assessed using tubule formation assay. The co-immunoprecipitation results showed that LETM1 could bind to KIF14. The cytological and protein results demonstrated that interference with LETM1 caused downregulation of KIF14 expression, which led to inhibition of proliferation, invasion, migration and angiogenesis in ESCC cells. Taken together, interfering with LETM1 to downregulate KIF14 may become a new target for ESCC treatment.
