Abstract
Long non-coding RNA (lncRNA) urothelial carcinoma associated 1 (UCA1) has been reported to be involved in the development and progression of many types of tumors including breast cancer, gastric cancer, and bladder cancer. However, the exact effects and molecular mechanisms of UCA1 in glioma progression remain unclear up to now. In this study, we firstly found that UCA1 was upregulated in glioma tumor samples and negatively correlated with survival time. Then, we investigated the role of UCA1 in human glioma cell lines. Our results showed that upregulation of lncRNA-UCA1 in glioma tissues and cell lines could promote glioma cell proliferation and migration through interaction with miR-182, and knockdown of UCA1 inhibited the proliferation and migration of human glioma cell. In addition, miR-182 dependent inhibitor of apoptosis-stimulating protein of p53 (iASPP) was required in the regulation of UCA1 induced glioma cell proliferation. Taken together, UCA1 might promote proliferation and migration of glioma, to regulate the tumor growth and metastasis via miR-182 dependent iASPP regulation. Therefore, lncRNA-UCA1 could be regarded as a therapeutic target in human glioma.
