The prognostic implications and physiological effect of LINC02875 are unknown in hepatocellular carcinoma (HCC). We sought to examine the prognostic value of LINC02875 in HCC and assessed its role in HCC cellular function. LINC02875 expression was evaluated by RT-qPCR in HCC specimens and cell lines. LINC02875 expression was subjected to assess the correlation with clinical parameters by Chi-squared test and overall survival by Kaplan – Meier curve and Cox regression analysis. The effects of LINC02875 on the biological characteristics of HCC cells were studied by MTS and Transwell assay. LINC02875 was high-expressed in HCC, and this was associated with unfavorable clinical features and poor prognosis of HCC, especially HBV-related HCC. Knockdown of LINC02875 inhibited the proliferation, migration, and invasion of HCC cells. miR-485–5p was a downstream microRNA of LINC02875. LINC02875 affects the prognosis of HCC patients, especially HBV-related ones. LINC02875 represents a suitable therapeutic target for HCC.
