Abstract

Long noncoding RNA placenta‑specific 2 (PLAC2) blocks the cancer cell cycle in glioma, suggesting its tumor‑suppressive role. The present study aimed to investigate the role of PLAC2 in retinoblastoma (Rb). It was found that PLAC2 was downregulated in Rb tissues and was not affected by the development of Rb. PTEN was also downregulated in Rb and positively correlated with PLAC2. In Rb cells, PLAC2 over‑expression resulted in the upregulated expression of PTEN, while PTEN over‑expression did not affect PLAC2 expression. PLAC2 and PTEN over‑expression caused an increased apoptotic rate of Rb cells. PTEN small interfering RNA silencing led to a decreased apoptotic rate and attenuated the effects of PLAC2 over‑expression. Therefore, PLAC2 regulates PTEN in Rb and participates in the regulation of cancer cell apoptosis.
