Abstract

MicroRNAs (miRs) are essential regulators in the development and progression of cancer. The role of miR-494-3p in endometrial cancer (EC) has not yet been investigated. In the present study, the expression levels of miR‑494‑3p were significantly upregulated in EC tissues compared with adjacent normal tissues. Furthermore, upregulation of miR‑494‑3p in patients with EC indicated poorer prognosis; miR‑494‑3p overexpression significantly promoted the proliferation, migration and invasion of HHUA and JEC cells in vitro. Consistently, inhibition of miR‑494‑3p in HHUA cells significantly suppressed tumor growth in vivo in a xenograft model. Additionally, phosphatase and tensin homolog (PTEN) was revealed to be a direct target of miR‑494‑3p in EC cells. Furthermore, overexpression of miR‑494‑3p inhibited PTEN expression and consequently activated the downstream phosphoinositide 3‑kinase/protein kinase B (PI3K/AKT) signialing pathway. Restoration of PTEN or inhibition of PI3K/AKT pathway also abolished miR‑494‑3p‑mediated proliferation, migration and invasion of HHUA and JEC cells. In summary, the results of the present study revealed the importance of the miR‑494‑3p/PTEN/PI3K/AKT axis in the progression of EC, which may provide novel insight into potential therapeutic targets for the treatment of EC.
