| Abstract: | Oesophageal cancer (OC) is one of the most fatal malignancies in the world, and chemoresistance restricts the therapeutic outcome of OC. Long noncoding RNA (lncRNA) was reported to play roles in multiple cancer types. Yet, the function of lncRNA in chemoresistance of OC has not been reported. A lncRNA gene, PCAT‐1, showed higher expression in OC tissues, especially higher in secondary OC compared with normal mucosa tissues. Overexpression of PCAT‐1 increased the proliferation rate and growth of OC cells. Inhibition of PCAT‐1 decreased proliferation and growth of OC cells, and increased cisplatin chemosensitivity. In a mouse OC xenograft model, PCAT‐1 inhibition repressed OC growth in vivo. Therefore, PCAT‐1 may potentially serve as a therapeutic target for treating OC. PCAT‐1 promotes development of OC and represses the chemoresistance of OC to cisplatin, and silencing of PCAT‐1 may be a therapeutic strategy for treating OC. |
