Long non-coding RNAs (lncRNAs) have been identified as critical regulators in tumorigenesis. In our present study, we measured the level of small nucleolar RNA host gene 5 (SNHG5) in bladder cancer (BC) tissues and cell lines, and the correlation of the level of SNHG5 with clinicopathological features and prognosis of BC patients was analyzed. Reverse transcription-quantitative polymerase chain reaction was performed to determine the level of SNHG5 in the BC tissues and cell lines. The Kaplan‑Meier method was used to analyze the long‑term survival outcomes. MTT and colony formation assays were applied to assess the influence of SNHG5 on cell proliferation ability. Flow cytometry was used to measure the function of SNHG5 on cell cycle and apoptosis rate. SNGH5 was found upregulated in BC tissues and cell lines and a high level of SNGH5 was correlated with a poor prognosis. Silencing SNHG5 inhibited the proliferation ability of BC cells and such a function was attributed to its influence on cells cycle and apoptosis. Our findings imply that SNHG5 was upregulated in BC tissues and played an important role in BC progression and may be a potential therapeutic target for BC patients.
