Abstract
Prostate cancer-associated transcript1 (PCAT-1) is a novel lncRNA that involved in cell apoptosis and proliferation of prostate cancer. However, the role of PCAT-1 on gastric cancer remains unclear. In the present study, we found that PCAT-1 was increased in gastric cancer tissues and cell lines. Over-expression of PCAT-1 was correlated with poor overall survival in gastric cancer patients. PCAT-1 knockdown through shRNA in AGS and MGC-803 cells inhibited cell proliferation, migration and invasion by regulating CDKN1A. Our data suggested that PCAT-1 could play an oncogenic role in gastric cancer progression. Silencing PCAT-1 is a potential novel therapeutic approach for gastric cancer.
