Background Esophageal squamous cell carcinoma (ESCC) is one of the most common malignancies and frequent cause of cancer-related death worldwide. Long non-coding RNAs (lncRNAs) play regulatory roles and serve as biomarkers of multiple cancers, including ESCC. Our previous studies have confirmed that lncRNA Kinectin 1 antisense RNA 1 (KTN1-AS1) is highly expressed in ESCC and exerts oncogene function through RBBP4/HDAC1 complex.
Objective Our present study focused on exploring a novel molecular mechanism of KTN1-AS1 in ESCC.
Methods In this study, qRT-PCR assay, Western blot assay, Luciferase reporter assay, and RNA immunoprecipitation assay were conducted.
Results We found that KTN1-AS1 could bind to miR-885-5p in ESCC cells, and miR-885-5p was low expressed in ESCC. Overexpression of miR-885-5p inhibited esophageal cancer cells proliferation and invasion in vitro. Mechanistic analysis demonstrated that miR-885-5p specifically targeted striatin 3 (STRN3), and KTN1-AS1/miR-885-5p promoted the EMT process by Hippo pathway in STRN3/YAP1 dependent manner.
Conclusion To sum up, KTN1-AS1 facilitates ESCC progression by acting as a ceRNA for miR-885-5p to regulate STRN3 expression and the Hippo pathway, and KTN1-AS1 maybe used as a promising therapeutic target for ESCC.
