Long non‑coding RNAs (lncRNAs) play a crucial role in cancer development. However, researchers have yet to identify the underlying association between lncRNAs and ovarian cancer (OC). The aim of the present study was to examine the effect of lncRNA RHPN1‑AS1 (RHPN1‑AS1) on OC cells and tissues. Reverse transcriptase‑quantitative PCR (RT‑qPCR) was utilized to quantify RHPN1‑AS1, miR‑485‑5p, and
